Pros and cons of the BRI2 risk assessment method for wildlife strike management at Italian airports

Montemaggiori A & Eminente C.
Presentazione World Birdstrike Association Conference 2016 - Amsterdam, Decembre 5th-9th | 2016 |

Abstract

In 2011 ENAC (Italian CAA) released new standards regarding prevenCon of wildlife strike hazard at Italian airports regulaCng tasks, responsibiliCes, reporCng, environmental assessment, monitoring, operaCng procedures, training and risk assessment. At the same Cme a new standard for the wildlife strike risk assessment was introduced. The Birdstrike Risk Index (BRI2) takes into account the ecological characterisCcs of the wildlife communiCes present in each airport area, the local history of wildlife strikes, their effects on flight, the number of aircraQ movements, etc., and enable the comparison of results among different airports. AQer four years, the outcomes of this “new deal” at Italian civil airports will be presented. Pros and cons of the BRI2 will be discussed, and data about yearly risk level, number of wildlife strikes, wildlife presence, etc. will be provided. Two cases of clear evidence of the importance of the environmental management around the airports will be discussed.

Wildlife strike: relevance and solutions of a safety problem

Montemaggiori A
Presentazione III Congresso Nazionale sulla Fauna Problematica - Cesena, Palazzo del Ridotto - 24-26 Novembre | 2016 |

Abstract

Collisions between aircrafts and wildlife, mostly birds, are a serious hazard to aviation and have resulted in the loss of at least 245 aircraft and 276 lives in civil aviation since 1988. Non catastrophic wildlife strikes cause significant operational costs to the aviation industry as a result of repairs to damaged aircraft, delays and cancellations, insurance claims etc. The number of recorded wildlife strikes is increasing all over the world. In USA civil aviation this number has increased 7.4-fold from 1,851 in 1990 to a record 13,668 in 2014; in Italy increased from 348 in 2002 to 1,279 in 2015. The total cost to world commercial aviation has been conservatively estimated at $1.5 billion per year; the USA civil aviation industry, on average, spends $193 million every year, while at least €40 million is the annual cost of wildlife strike in Italy. Many populations of large bird (and mammal) species commonly involved in strikes have increased markedly in the last few decades and adapted to living in urban environments, including airports. The resident Canada goose (Branta canadensis) population in the USA and Canada increased from about 1.0 million to 3.6 million from 1990 to 2014. During the same time period, the North American snow goose (Chen caerulescens) population increased from about 2.6 million to 6.2 million birds. In Italy the breeding population of yellow-legged gull (Larus michahellis), one of the species most involved in wildlife strikes (birdstrikes), together with European kestrel (Falco tinnunculus) and common swift (Apus apus), doubled in the last 20 years. Most wildlife strikes occur in Italy from May to August, and during the morning. 81.8 % of them occur below 300 ft of altitude and 64% during landing of the aircraft. In order to manage the hazard, the International Civil Aviation Organization (ICAO) requires national aviation regulators to ensure the implementation of effective wildlife management policies on the airfields and their surroundings. In Italy ENAC (Italian CAA), through its Bird Strike Committee, provides detailed guidelines and regulations that meet all aspects of the problem such as reporting, environmental assessment, monitoring, operating procedures, training and risk assessment, by clearly identifying roles, tasks and responsibilities. Since 2011 the Italian airport operator has been given the task to monitor and identify potential sources for wildlife attraction also in the vicinity of the airport, and a standard for the wildlife risk assessment was introduced. This takes into account the ecological characteristics of the wildlife communities present in each airport area, the local history of wildlife strikes, their effects on flight, the number of aircraft movements, etc., and enable the comparison of results among different airports. In the presentation wildlife strike relevance, mitigating solutions and their updated results are showed in detail at national level.

Gli Storni di Roma

Abstract

È una notizia che circola da giorni: la città di Roma preda di una miriade di storni che mettono in crisi la viabilità cittadina dopo aver reso scivoloso il manto stradale con le loro deiezioni. I numeri degli esemplari presenti a Roma forniti in questi giorni è variabile, così come le misure adottate per contrastare un fenomeno molto comune in tante metropoli del mondo. Quanti sono gli storni che vivono a Roma e perché solo adesso costituiscono un problema? Parliamo di un milione di esemplari. Lo storno è un animale molto adattabile e ha una serie di vantaggi a vivere in folti gruppi. Durante il giorno si reca nella campagne a cercare cibo e la notte torna in città, dove le temperature sono più alte, comportandosi come una sorta di pendolare al contrario. In tutto il mondo è in corso una “guerra allo storno”, portata avanti con i metodi più bizzarri, dall’introduzione di alcuni falchi nell’ecosistema fino, addirittura, alla dinamite, utilizzata in Belgio. Tuttavia è bene considerare soluzioni di altro tipo, inquadrando meglio il fenomeno, come ci ha spiegato Alessandro Montemaggiori, ornitologo dell’Università “La Sapienza” di Roma, in questa intervista. Ma le soluzioni dovrebbero non farci rinunciare a un grande spettacolo. I foltissimi stormi di storni sul cielo di Roma, che compatti disegnano geometrie variabili e affascinanti, rappresentano uno spettacolo straordinario che non è sfuggito a molti documentaristi internazionali.

On how much biodiversity is covered in Europe by national protected areas and by the Natura 2000 network: insights from terrestrial vertebrates

Maiorano L, Amori, G, Montemaggiori A, Rondinini C, Santini L, Saura S., Boitani L.
Articolo scientifico Conservation Biology. doi: 10.1111/cobi.12535 | 2015 |

Abstract

The European Union has made extensive biodiversity conservation efforts with the Habitats and Birds Directives and with the establishment of the Natura 2000 network of protected areas, one of the largest networks of conservation areas worldwide. We performed a gap analysis of the entire Natura 2000 system plus national protected areas and all terrestrial vertebrates (freshwater fish excluded). We also evaluated the level of connectivity of both systems, providing therefore a first estimate of the functionality of the Natura 2000 system as an effective network of protected areas. Together national protected areas and the Natura 2000 network covered more than one-third of the European Union. National protected areas did not offer protection to 13 total gap species (i.e., species not covered by any protected area) or to almost 300 partial gap species (i.e., species whose representation target is not met). Together the Natura 2000 network and national protected areas left 1 total gap species and 121 partial gap species unprotected. The terrestrial vertebrates listed in the Habitats and Birds Directives were relatively well covered (especially birds), and overall connectivity was improved considerably by Natura 2000 sites that act as stepping stones between national protected areas. Overall, we found that the Natura 2000 network represents at continental level an important network of protected areas that acts as a good complement to existing national protected areas. However, a number of problems remain that are mainly linked to the criteria used to list the species in the Habitats and Birds Directives. The European Commission initiated in 2014 a process aimed at assessing the importance of the Birds and Habitats Directives for biodiversity conservation. Our results contribute to this assessment and suggest the system is largely effective for terrestrial vertebrates but would benefit from further updating of the species lists and field management.

Articolo scientifico Bollettino dell’Associazione Romana di Entomologia, 69 (1-4): 1-5. | 2014 |

Abstract

IIxodes (Ixodes) festai Rondelli, 1926 è una zecca poco conosciuta di cui si ignorano gli aspetti biologici ed ecologici, la diffusione, il rischio sanitario associato e le caratteristiche degli sta- di immaturi. In questa nota viene riportato il ritrovamento di quattro esemplari della specie, tutti di sesso femminile, catturati in Sardegna in provincia di Cagliari, due nel 2007 e due nel 2014. Le catture, che hanno avuto carattere occasionale, sono state effettuate su Turdus merula e su T. philomelos, specie aviarie migranti parziali. Gli esemplari sono stati identificati dal punto di vista morfologico e costituiscono un contributo alle rare segnalazioni della specie, che ad oggi costitu- iscono gli unici dati sulla sua diffusione in Italia. È importante sottolineare che questa specie ne- cessita comunque di ricerche ulteriori anche sul ruolo potenziale come vettore di agenti patogeni.

Abstract

First successful reproduction of Black Stork Ciconia nigra in Latium (Central Italy)

Since 2002 Black stork attempted to breed unsuccessfully in a deep forested canyon in Viterbo’s Province (Latium). On 10.08.2014 three juveniles successfully left a big nest built on Quercus ilex grown up on a side of the canyon. It is the first time the species successfully reproduces in Central Italy, while present only in Piedmont (N. Italy) and in Campania, Apulia and Basilicata (S. Italy).

L'ultimo volo di Martha, la colomba migratrice

Albicocco C, Occhipinti S (a cura di)
Intervista Moebius Radio 24 - 11 Marzo | 2014 |

Riassunto

Tre miliardi di esemplari in un unico stormo. Una straordinaria peculiarità che faceva della colomba migratrice la specie di uccello più numerosa al mondo. Faceva, perché ora non esiste più. L’ultimo esemplare è morto cento anni fa esatti, nel 1914, in uno zoo americano. Si chiamava Martha ed era l’unica testimonianza vivente di una specie, Ectopistes migratorius, portata all’estinzione dalla follia umana. Così l’ornitologo JJ Audubon descrive la scena terrificante della strage di uno stormo di colombe migratrici a opera dell’uomo: "Quando si accesero le torce lo spettacolo che si appalesó ai miei occhi era tanto incredibile quanto orrido. Gli uccelli colpiti si ammassavano a terra, intorno ai tronchi, formando grandi mucchi. Qua e là i rami cadevano per il peso degli uccelli posati, trascinandosi dietro alcune vittime. Tutto intorno a me c’era tumulto, furore e pazzia. Non si notava neanche più il rumore dei fucili. Mi rendevo conto che qualcuno aveva sparato solo quando vedevo il cacciatore ricaricare il suo fucile. Nessuno si azzardava a entrare nel bosco: tutti uccidevano dai margini. Anche i maiali erano ancora nei recinti: il loro intervento era previsto solo per l’indomani... Il silenzio si reimpadroní dei boschi solo verso l’alba. Poco prima che il sole spuntasse, le colombe sopravvissute si levarono in volo, proseguendo la migrazione, mentre l’ululato dei coyote, dei lupi ci ricordava che non eravamo gli unici predatori nel bosco. A quel punto anche gli uomini osarono avventurarsi nel bosco, fra le colombe morte, quelle ferite, quelle moribonde, quelle mutilate. Gli uccelli vennero raccolti, messi in mucchietti ordinati, finché ciascuno si impadroní di tanti quanti ne potesse ragionevolmente accatastare. Poi si lasciarono liberi i maiali, perché si nutrissero di quelle che rimanevano al suolo".
Ermanno Bencivenga, filosofo dell’università di California e autore di numerosi saggi, ha ricordato la scomparsa di Martha in un articolo recentemente apparso sull’inserto della Domenica del Sole 24 ore. Con Bencivenga e con Alessandro Montemaggiori, ornitologo de La sapienza di Roma, raccontiamo la storia di questa specie straordinaria. Tanti americani in quel primo settembre del 1914 piansero davanti alla voliera vuota di Martha, incommensurabili le lacrime versate in seguito per la scomparsa di migliaia di specie, ma la lezione non l’abbiamo ancora imparata.

Modelling the response of European breeding birds to climate change: combining expert-based and statistical approaches

Montemaggiori A, Guisan A, Thuiller W, Zimmermann NE, Maiorano L
Presentazione XVII Convegno Italiano di Ornitologia - Trento 11-15 September| 2013 |

Riassunto

Climate change is emerging as the greatest threat to natural communities in most of the world’s ecosystems, with mid- and long-range scenarios expected to produce greater extinction rates than habitat loss, currently deemed the top threat to biodiversity. One in eight species of bird is pushed towards extinction by climate change, according to the latest assessment of the IUCN. Time shifting and alteration of phenology, shifting and shrinking of geographical distributions and community disruption are only some of the direct and indirect consequences of climate change on bird populations. This has been clearly demonstrated by many long-time scale field studies and species- and location-specific analyses. Effects of climate change on breeding bird species are often predicted by projecting into future climate scenarios the current species’ climate niche, as estimated with correlative species distribution models. Although widely used and, often, highly successful, these models (and the related projections) are generally calibrated considering only climate variables, without accounting for habitat, biotic interactions and dispersal distances. In order to build more realistic scenarios for changes in the distribution of species breeding in continental Europe, we propose a modeling approach based on the combination of state-of-the-art bioclimatic models, with expert-based habitat suitability and distance to current distribution. Thus, for each species, we developed three layers: a) a bioclimatic model calibrated with an ensemble forecasting approach, considering six climatic variables (annual mean temperature, annual precipitation, mean temperature of the coldest month, growing degree days, summer and winter precipitation) and species’ occurrences according to EBCC Atlas’ 50 x 50 km cells with semi-quantitative data and high coverage completeness; b) an expert-based habitat suitability model which considers land use (Globe Cover), elevation (SRTM) and distance to water (as mapped by CCM21 database) and c) the distance from the present distribution of the species, mapped according to BirdLife. Assuming that the three layers are largely independent, we calculated for each species a final model of the relative probability of presence by multiplying the three maps. We evaluated the reliability of the models using independent points of presence collected mainly in Italy, Spain, UK, Sweden, and Norway. In particular, we calculated the Boyce index (an index of the calibration capacity of the models) for both the classical bioclimatic model and for the final model of relative probability of presence. Our results clearly demonstrate that our approach produces more accurate and better performing models compared to simple bioclimatic ones. Combining our approach with future scenarios for land use and climate, it will be possible to build more robust models showing potential changes in species distribution. Furthermore, it will be possible to incorporate also models of species’ biotic interactions and dispersal distances, providing a biologically richer outcome.

Threats from climate change to terrestrial vertebrate hotspots in Europe

Articolo scientifico PLoS ONE 8(9): e74989 | 2013 |

Riassunto

We identified hotspots of terrestrial vertebrate species diversity in Europe and adjacent islands. Moreover, we assessed the extent to which by the end of the 21st century such hotspots will be exposed to average monthly temperature and precipitation patterns which can be regarded as extreme if compared to the climate experienced during 1950-2000. In particular, we considered the entire European sub-continent plus Turkey and a total of 1149 species of terrestrial vertebrates. For each species, we developed species-specific expert-based distribution models (validated against field data) which we used to calculate species richness maps for mammals, breeding birds, amphibians, and reptiles. Considering four global circulation model outputs and three emission scenarios, we generated an index of risk of exposure to extreme climates, and we used a bivariate local Moran’s I to identify the areas with a significant association between hotspots of diversity and high risk of exposure to extreme climates. Our results outline that the Mediterranean basin represents both an important hotspot for biodiversity and especially for threatened species for all taxa. In particular, the Iberian and Italian peninsulas host particularly high species richness as measured over all groups, while the eastern Mediterranean basin is particularly rich in amphibians and reptiles; the islands (both Macaronesian and Mediterranean) host the highest richness of threatened species for all taxa occurs. Our results suggest that the main hotspots of biodiversity for terrestrial vertebrates may be extensively influenced by the climate change projected to occur over the coming decades, especially in the Mediterranean bioregion, posing serious concerns for biodiversity conservation.

New standards for preventing wildlife strike hazard at Italian airports: results of the first year of application

Montemaggiori A, Ciotta U, Grillanda R, Eminente C
Presentazione XXX International Bird Strike Conference - Stavanger, Norway: 25-29 June | 2012 |

Abstract

In December 2011 ENAC (Italian CAA) released new standards regarding prevention of wildlife strike hazard at Italian airports (Regolamento per la Costruzione e l’Esercizio degli Aeroporti and Circolare ENAC APT-01B). Providing detailed guidelines, the new rules regulate all aspects of the problem such as reporting, environmental assessment, monitoring, operating procedures, training and risk assessment,. Moreover roles, tasks and responsibilities are clearly identified. For the first time the airport operator has been given the task to monitor and identify potential sources for wildlife attraction in the vicinity of the airport. At the same time a new standard for the wildlife risk assessment was introduced (BRI2) to replace the out of date previous one (number of yearly strikes out of 10.000 aircraft movements). BRI2 takes into account the ecological characteristics of the wildlife communities present in each airport area, the local history of wildlife strikes, their effects on flight, the number of aircraft movements, etc., and enable the comparison of results among different airports. How this new standard changes the overall picture of Italian airports in terms of wildlife risk assessment is showed in the present contribution.

Birdstrike Risk Index (BRI2): a new approach to the wildlife strike risk assessment

Poster XXX International Bird Strike Conference - Stavanger, Norway: 25-29 June | 2012 |

Abstract

An ecological approach to wildlife strike risk assessment was implemented and the resulting algorithm (BRI2) was used to assess the wildlife risk at Italian airports (http://bit.ly/HbiNNK). The BRI2 takes into account the ecological characteristics of the wildlife communities present in each airport area, the local history of wildlife strikes, their effects on flight, the number of aircraft movements, etc. The main achievement is a site-specific analysis that avoids flattening wildlife strike events on a large scale while maintaining comparable airport risk assessments. The Birdstrike Risk Index (BRI2) is a sensitive tool that provides different time scale results allowing appropriate management planning. The methodology applied has been developed together with the Italian Civil Aviation Authority (ENAC), which decided to introduce it as the new standard regarding wildlife strike risk assessment at Italian airports (Regolamento per la Costruzione e l’Esercizio degli Aeroporti and Circolare ENAC APT-01B).

Il cuculo volò sul nido altrui

Gallavotti B (a cura di)
Intervista Moebius Radio 24 - 21 Giugno | 2011 |

Riassunto

Non ha dubbi il piccolo beccamoschino africano, chiamato anche prinia: quell'uovo non è suo. E quindi passa decisamente all'azione. La posta in gioco è troppo alta: se quell'uovo si schiudesse, il nido avrebbe un piccolo abitante abusivo, che quasi certamente determinerebbe la morte di tutti i pulcini nati dalle uova del legittimo proprietario del nido. Un nuovo studio dell'università di Cambridge svela sorprendenti segreti della lunghissima lotta fra i beccamoschini africani e i tessitori parassiti che da tempo immemorabile ne insidiano le covate, ed è anche l'occasione per ricordare l'analogo duello che nelle nostre foreste vede protagonisti, nel ruolo dei cattivi, i cuculi.

Wildlife strike risk assessment in several Italian airports: lessons from BRI and a new methodology implementation

Soldatini C, Albores-Barajas YV, Lovato T, Andreon A, Torricelli P, Montemaggiori A, Corsa C, Georgales V
Articolo scientifico PLoS ONE 6(12): e28920 | 2011 |

Riassunto

The presence of wildlife in airport areas poses substantial hazards to aviation. Wildlife aircraft collisions (hereafter wildlife strikes) cause losses in terms of human lives and direct monetary losses for the aviation industry. In recent years, wildlife strikes have increased in parallel with air traffic increase and species habituation to anthropic areas. In this paper, we used an ecological approach to wildlife strike risk assessment to eight Italian international airports. The main achievement is a site-specific analysis that avoids flattening wildlife strike events on a large scale while maintaining comparable airport risk assessments. This second version of the Birdstrike Risk Index (BRI2) is a sensitive tool that provides different time scale results allowing appropriate management planning. The methodology applied has been developed in accordance with the Italian Civil Aviation Authority, which recognizes it as a national standard implemented in the advisory circular ENAC APT-01B.

Interview Moebius Radio 24 - 12 Febbraio | 2010 |

Abstract

Sulle tracce delle sterne codalunga (Sterna paradisaea, Sterna Artica), gli scienziati hanno scoperto che questi uccelli coprono 35.000 chilometri in 2-3 mesi per spostarsi da un Polo all'altro del pianeta, per poi tornare indietro alcuni mesi dopo. Ciascuna tappa di queste migrazioni poi può durare fino a 500 chilometri e alla fine della sua esistenza una sterna può aver coperto tre volte la distanza di un viaggio di andata e ritorno per la Luna: non male per un passeriforme del peso di poche decine di grammi! Ci siamo fatti raccontare questa epica migrazione, e il modo in cui noi umani riusciamo a seguirla, da una protagonista: una sterna codalunga in procinto di iniziare la travesata, affiancata dall'esperto ornitologo Alessandro Montemaggiori.

Conservation of migratory species and their processes

A panel of experts elaborated a proposal for an efficient strategy of conservation of the migratory species in Italy. Within birds raptors, passerines and waterfowl were considered. Conservation measures were proposed for migrating invertebrates, freshwaters fishes, cetaceans and bats. Eight targets were identified to reduce main threats for migratory species: habitat loss and degradation, legal and illegal shooting, infrastructures’ impact, climate change, toxics, monitoring.

Il problema del birdstrike in italia: situazione attuale e scenari futuri

Riassunto

Birdstrike in Italy: Present and Future

The risk of birdstrike is a serious problem all over the world. In January 2009 a flock of Canadian geese did force an Airbus A320 jet to crash-land on the Hudson River in New York, while in November 2008 a B-738 jet crashed in Roma Ciampino because of Starlings. In North America, Italy and most of the other countries bird strike haz- ards are dramatically increasing (in USA during 2009 more than 10.000 birdstrikes occurred, while in Italy they were 912), also because the populations of many bird species have increased dramatically since the last twenty years. In Italy the breeding population of Larus michahellis, one of the most involved species in birdstrikes, to- gether with Kestrel (Falco tinnunculus) and Swift (Apus apus), doubled in the last 20 years. Most birdstrikes occur between May and September and during the morn- ing; 67% of them occur below 300 ft of altitude and 64% during landing (34% dur- ing take-off). The Bird Strike Committee Italy is the task force dealing with this is- sue since 1987. It is an ENAC (Italian Civil Aviation Authority) operative structure and since then collected many data from more than 40 airports. It achieved many re- sults, especially under the reporting point of view, and for the next future is planning several activities in order to mitigate and better monitor the birdstrike hazard in Italy.

Beyond falconry between tradition and modernity: a new device for bird strike hazard prevention at airports

Battistoni V, Montemaggiori A, Iori P
Atti Convegno XXVIII International Bird Strike Committee Meeting - Brasilia - 24-28 November| 2008 |

Riassunto

Most accredited studies in Italy and all over the world emphasize the problems related to traditional falconry used as a means against bird hazard at airports. Some negative features of using falcons are the impossibility to be employed during some periods of the year and adverse weather conditions, unforeseen animal behaviour, their biological needs, the tight dependency on the falconer and the limited employment over the day. Above all, high costs play a key role due to the value of the animals, to their training, to the number of birds necessary to be effectively operated on a medium/large size airport and finally to the employment features. The attempts to use remote-controlled model aircrafts instead of real falcons proved to be unsuccessful because of the habituation effect it produced on other birds, that are certainly harassed by the device, but do not recognize it as a natural bird of prey, whose hunting area must be avoided. So it is the frightening effect that is missing, upon which also other dispersal methods are based, such as distress calls or predator effigies. The use of full scale bird of prey accurate reproductions, engine powered and fully remote-controlled, seems to have reached the goal to match the natural predator effectiveness with employment flexibility, cost reduction and mass production.

Temperature and rainfall anomalies in Africa predict timing of spring migration in trans-Saharan migratory birds

Saino N, Rubolini D, Jonzén N, Ergon T, Montemaggiori A, Stenseth NC, Spina F
Articolo scientifico Clim Res 35:123-134 | 2007 |

Riassunto

The long-term advance in the timing of bird spring migration in the Northern Hemisphere is associated with global climate change. The extent to which changes in bird phenology reflect responses to weather conditions in the wintering or breeding areas, or during migration, however, remains to be elucidated. We analyse the relationships between the timing of spring migration of 9 species of trans-Saharan migratory birds across the Mediterranean, and thermal and precipitation anomalies in the main wintering areas south of the Sahara Desert and in North African stopover areas. Median migration dates were collected on the island of Capri (southern Italy) by standardized mist-netting during 1981 to 2004. High temperatures in sub-Saharan Africa (Sahel and Gulf of Guinea) prior to northward migration (February and March) were associated with advanced migration. Moreover, birds migrated earlier when winter rainfall in North Africa was more abundant. The relationships between relevant meteorological variables and timing of migration were remarkably consistent among species, suggesting a coherent response to the same extrinsic stimuli. All these results were obtained while statistically controlling for the long-term trend towards the earlier timing of spring migration across the Mediterranean that has been documented in previous analyses of the same dataset, a trend that was confirmed by the present analyses. In conclusion, our results suggest that thermal conditions in the wintering quarters, as well as rainfall in North African stopover areas, can influence interannual variation in migration phenology of trans-Saharan migratory birds, although the ecological mechanisms that causally link meteorological conditions to the timing of migration remain a matter of speculation.

Articolo scientifico Ornis Svecica 16, 27-33 | 2006 |

Riassunto

Some migratory birds have advanced their spring arrival to Northern Europe, possibly by increasing the speed of migration through Europe in response to increased temperature en route. In this paper we compare the phenology of spring arrival of seven trans-Saharan migrants along their migration route and test for patterns indicating that migration speed varied over the season using long-term data collected on the Italian island of Capri and at Ottenby Bird Observatory, Sweden. There was a linear relationship between median arrival dates on Capri and at Ottenby. The slope was not significantly different from one. On average, the seven species arrived 15 days later at Ottenby compared to Capri. There was a (non-significant) negative relationship between the species-specific arrival dates at Capri and the differences in median arrival dates between Capri and Ottenby, possibly indicating a tendency towards faster migration through Europe later in the season. To what extent different species are able to speed up their migration to benefit from the advancement of spring events is unknown.

The importance of bird monitoring at airports: the case of Fiumicino, Roma

According to a simple - but effective - methodology to monitor bird community and scaring devices adopted and tested at Fiumicino Airport (Roma) since 1989, the information gathered during the period 1989-90 and the period 1995-96 were compared. The obtained results show a decrease in the presence of Gulls (Larus cachinnans and Larus ridibundus) of more than 80%; Starlings (Sturnus vulgaris) decreased of 74,7% and Lapwings (Vanellus vanellus) of 24,2%. These results strongly highlight the importance of a continuous monitoring effort of the avian community at airports, in order to better calibrate and implement the bird-avoidance strategy, and to check the obtained results.

Spring migratory routes of eight trans-Saharan Passerines through the central and western Mediterranean; results from a network of insular and coastal ringing sites

Pilastro A, Macchio S, Massi A, Montemaggiori A, Spina F
Articolo scientifico Ibis 140: 591-598 | 1998 |

Riassunto

Detailed information on spring migration routes of songbirds across the Mediterranean is still scanty. Results are presented here from a study on the occurrence of eight Palaearctic-African migrants across the western and central Mediterranean based on ringing data collected during the Progetto Piccole Isole, a co-ordinated project based on standardized mist netting at 21 islands and coastal stations. The species were Melodious Warbler Hippolais polyglotta, Icterine Warbler Hippolais icterina, Bonelli's Warbler Phylloscopus bonelli, Wood Warbler Phylloscopus sibilatrix, Pied Flycatcher Ficedula hypoleuca, Collared Flycatcher Ficedula albicollis, Red-backed Shrike Lanius collurio and Woodchat Shrike Lanius senator. Their capture frequencies were expressed as the frequency of each species relative to the total number of migrants ringed at each station in order to correct for differences in capture effort between stations. For most species, the detailed, quantitative results confirmed the scanty information available so far, whereas in the case of Melodious Warbler and Bonelli's Warbler, evidence of undescribed and unexpected migration routes was found. These results suggest that standardized mist netting provides an important method for studying the migratory routes of small birds, in particular for those species which are not frequently ringed in their breeding and wintering grounds.

Back from Africa: who's running ahead? Differential migration of sex and age classes in Palearctic-African spring migrants

Spina F, Massi A, Montemaggiori A
Articolo scientifico Ostrich 65:139-150 | 1994 |

Riassunto

The differential migration of sex and age classes in 16 species of Palearctic-African migrants during their northward spring journey through the Central Mediterranean has been investigated from a large data set collected on 4 Italian islands during the “Progetto Piccole Isole”. Species investigated were: Euro Nightjar Caprimulgus europaeus, Barn Swallow Hirundo rustica, Yellow Wagtail Motacill flava. Common Redstart Phoenicurus phoenicurus, Whinchat Saxicola rubetra, Northern Wheatear Oenanthe oenanthe, Black-eared Wheatear O. hispanica, Subalpine Warbler Sylvia cantillans, Whitethroat S. communis, Blackcap S. atricapilla, Collared Flycatcher Ficedula albicollis, Pied Flycatcher F. hypoleuca. Golden Oriole Oriolus oriolus, Red-backed Shrike Lanius collurio, Woodchat Shrike L. senator, Ortolan Bunting Emberiza hortulana. The seasonal trapping patterns of males and females have been analysed both from the total samples and on a yearly basis. Males have been found passing earlier than females in 14 out of 16 cases, with differences reaching the level of significance in 13 out of 16 species. In the selected species, although the general trapping patterns may vary significantly among years, a temporal gap between males and females remains a fairly constant feature. In a subsample of 13 1 adults are found to migrate earlier than yearlings in 18 or 26 cases (significant differences found in 12 cases), with a slightly higher incidence of earlier movements of adult birds in females than males. This strategy seems to be another feature of spring migration, as confirmed by more detailed analyses referred to samples collected on single years and/or sites.

Atti Convegno XXII Bird Strike Committee Europe Meeting - Vienna - 29 August- 2 September| 1994 |

Riassunto

In order to give to each aerodrome a rough risk value regarding the potential bird hazard, recoveries of ringed birds (data from Italian Ringing Scheme) have been used. Six Italian International airports were selected as example sites (Milan, Venice, Genoa, Roma, Cagliari and Palermo) and recoveries around each site were analyzed. For each bird species a risk value was calculated considering weight, strike statistics, habitat and behaviour. Examples of montly and seasonal risk scales are shown for selected sites. This kind of analysis can be a usefull tool in order to give important information for bird strike hazard prevention.

Articolo scientifico Die Vogelwarte 37 (Sonderheft): 1-94 | 1993 |

Riassunto

In 1988, the Istituto Nazionale per la Fauna Selvatica (formerly Istituto Nazionale di Biologia della Selvaggina) - Italian Ringing Scheme within EURING, Started a project to investigate the patterns of sea crossing by passerine migrants coming from their winter quarters in spring, lite main aims of this project, called Progetto Piccole Isole (Small Islands Project, PPl) are: a) to define the seasonal migratory patterns of different species and categories of migrants; b) to study the daily migratory patterns, in order to clarify if a non stop or intermittent flight strategy is used, with special reference to long-distance migrants; c) to investigate the geographical origin of the bird's which migrate through the Mediterranean in spring, and identify the different populations involved; d) to analyze the physical conditions of birds at different stages of sea crossing, and define the role played by the small islands as resting areas; e) to identify the main problems the migrants face while crossing the Mediterranean in spring, in terms of habitat and food availability, with special attention to conservation aspects. The project has been regularly running since 1988 on a constantly increasing number of sites within the Mediterranean. In this paper we will present some general results which originated from the first two years of the project, and referred to the 4 islands which could fully cover both ringing periods.

Winter song activity of birds in a mediterranean area

During December and January 1987-88 fully singing birds have been recorded in a Lathyro-Quercetum cerris wood, and in a meadow, in a Mediterranean woodland near Roma. Only the breeding species showed a full song activity, with a significant correlation between singing activity and density of birds (n° breeding pairs/10 ha) in the wood, and between n° of records (songs) and ten-day periods in Great Tit, Wren and Serin. The last two species, recorded in both area, singing only in wood (the breeding habitat). A progress in sing activity seems to happen in Short-toed Treecreeper and Blackcap too, according to the seasonal progress. Therefore we suggest that the winter singing activity, has a precocious breeding territory’s defense significance, instead of winter feeding territory’s defense.

Abstract

Der Vogelbestand am Internationalen Flughafen Fiumicino in Rom ist von 1989 bis 1991 in einem Projekt untersucht worden, das von der Abteilung Operative Sicherheit der römischen Flughafengesellschaft vergeben wurde. Es wurden Linientaxierungen durchgeführt, und mehr als 1.700 tägliche Erfassungsbögen wurden ausgefüllt. 88 Vogelarten wurden beobachtet, davon 37 Nichtsingvogel- und 51 Singvogelarten. Weißkopfmöwe (Larus cachinnans), Lachmöwe (Larus ridibundus), Kiebitz (Vanellus vanellus), Star (Sturnus vulgaris) und Nebelkrähe (Corvus corone cornix) waren die für das Vogelschlagrisiko bei Start und Landung wichtigsten Arten. Daten über deren Aufenthaltsort, Anzahl, Anwesenheitsperioden, Schwarmbildung, Standortansprüche, tageszeitliches Auftreten, Ansprechen auf Vergrämungsgeräte usw. sind über zwei Jahre gesammelt worden. die gesamten Ergebnisse der Untersuchungen werden gegenwärtig verwendet,, um ein völlig neues Vergrämungsprogramm zu entwickeln.
