| 2 | Flight feather moult in Western Marsh Harriers during autumn migration显示文摘Background:Most of long-distance migratory raptors suspend moult during migration but detailed information is patchy for most of the Palearctic species.The aim of this research is to verify if active moulting in migrating Western Marsh Harriers occurs and to quantify the extent of moulting along the season focusing on primary feathers.Methods:During a whole post-breeding migration at the Strait of Messina in Southern Italy,we gathered information about symmetrical flight feather moult from 221 adults by taking pictures of raptors passing at close range.Results:We found active moulting primaries during autumn migration in 48.4% of our samples.Slight differences on the extension and timing among sex classes were recorded during the season,with adult females showing a more advanced moult stage than adult males.Conclusion:The finding that the extension of the suspended moult was already defined in migratory individuals might be explained as an adaptation to minimize the energy required for moulting during migration. | Juan Ramírez Michele Panuccio | 2019 | Avian Research2019，10，1： | 1 |
| 3 | Migration of the Western Marsh Harrier to the African wintering quarters along the Central Mediterranean flyway:a 5-year study显示文摘Background: The Western Marsh Harrier(Circus aeruginosus) is a partial migrant with the populations from Eastern and Northern Europe migrating south to sub-Saharan Africa. During the autumn migration, that is peaking in Septem ber, harriers move on a broad front heading SW and undertake long sea-crossings en route to their wintering quarters, passing in substantial numbers through Italy and Malta with the highest concentrations recorded at the Strait of Messina. Most of the individuals migrating across the Strait are heading for the wintering quarters in Africa, while fewer spend the winter in Sicily.Methods: In a 5-year study(2011-2015), between 26 August and 30 September, we determined age and sex of autumn migrating harriers through this flyway. In 2014 we determined, by marine radar and optical range finder, the flight altitude of migrating harriers.Results: A total of 10,261 Western Marsh Harriers were counted during the whole study, with an average of 2052 per autumn season. Adults outnumbered juveniles and males outnumbered females. Harriers flew at lower altitudes during the morning while large flocks flew lower than single birds or small flocks.Conclusions: Our observations are consistent with previous surveys and confirm that adult males have a tendency to migrate over a long distance, while substantial numbers of adult females and juveniles do not head for the wintering quarters in Africa. Finally, flight patterns recorded can be explained by a more pronounced flapping flight of Western Marsh Harriers during migration. | Nicolantonio Agostini Michele Panuccio Alberto Pastorino Nir Sapir Giacomo Dell’Omo | 2017 | Avian Research2017，8，3： | 1 |
| 4 | Mining citizen science data to explore stopover sites and spatiotemporal variation in migration patterns of the red-footed falcon显示文摘Citizen scienee data have already been used to effectively address questions regarding migration,a fun dame ntal stage in the life history of birds.In this study,we use data from eBird and from 3 additional regional citizen scienee databases to describe the migration routes and timing of the red-footed falcon Falco vespertinus in the Mediterranean region across 8years(2010-2017).We further examine the seasonal and yearly variation in migration patterns and explore sites used during the species migration.Our results suggest that the autumn passage is spatially less variable and temporally more consistent among years than in spring and that birds migrate faster in spring than in autumn.The species seems to be more prevalent along the Central Mediterranean during spring migration,probably as a result of the clockwise loop migration that red-footed falcons perform.There was a high variation in annual median migration dates for both seasons as well as in migration routes across years and seasons.Higher variation was exhibited in the longitudinal component thus indicating flexibility in migration routes.In additi on,our results showed the species'preference for I owl a nds covered with cropla nd and mosaics of cropland and natural vegetation as stopover sites during migration.Stopover areas predicted from our distribution modeling highlight the importance of the Mediterranean islands as stopover sites for sea-crossing raptors,such as the red-footed falcon.This study is the first to provide a broad-scale spatiotemporal perspective on the species migration across seasons,years and flyways and dem on strates how citize n science data can inform future monitori ng and conservation strategies. | Anastasios Bounas Maria Solanou Michele PANUccio Sanja BARisic Taulant Bino Kiraz Erciyas-Yavuz Petar Iankov Christina Ieronymidou Christos Barboutis | 2020 | Current Zoology2020，66，5： | 0 |
