Article summary

The mild weather during March (especially at the end of the month) allowed the migration that began in February to continue; sometimes dramatically, as in the case of Common Cranes Grus grus and Red Kites Milvus Milvus. From the first 10 days the passages of many species increased, including those species returning from Africa (Garganey Anas querquedula, Black Stork Ciconia nigra, Black Kite Milvus migrans, and Mediterranean over-winterers). By contrast, the month of April was chilly, rainy and windy. This weather resulted in many returns and migration bottlenecks (e.g. Wrynecks Jynx torquilla and Common Swifts Apus apus). Flocks of Shovelers Anas clypeata, Eurasian Teal Anas crecca, Ring Ouzels Turdus torquatus, Bramblings Fringilla montifringilla, and even some Common Cranes, stayed longer than usual. The last of the over-wintering Rough-legged Buzzards Buteo lagopus stayed until 21 April.The very mixed weather of late April – early May resulted in many birds in passage making stopovers. Among them were a number of rare visitors: Booted Eagle Aquila pennata, Spotted Crakes Porzana porzana, Short-toed Lark Calandrella brachydactyla, Citine Wagtail Motacilla citreola… The influx of Whiskered Tern Chlidonias hybrida appears to be attributable to the severe drought that prevailed in southern Europe. Movements continued into late May. Thus the first European Nightjar Caprimulgus europaeus was reported only on the 19th, and Little Bittern Ixobrychus minutus on the 29th. During the spring there was not a single report of the Great Reed Warbler Acrocephalus arundinaceus, only one Corncrake Crex crex was heard, and fewer and fewer Turtle Doves Streptopelia turtur were seen. None of the spring-time Short-eared Owls Asio flammeus appears to have nested.
