Abstract 1
Despite an overall advancement in breeding area arrival, one of the latest spring arrivals in northwest Europe since 1950 of several trans-Saharan songbird species occurred in 2011. Year-round tracking of red-backed shrikes and thrush nightingales revealed that the cause of the delay was a prolongation of stopover time during spring migration at the Horn of Africa, which was affected by extreme drought. Our results help to establish a direct link at the individual level between changes in local climate during migration and arrival and breeding condition in Europe thousands of kilometers further north.
Засуха задерживает соловьев и сорокопутов на местах остановок на Африканском Роге. Это определили с помощью геолокаторов.
Молодцы парни, отличное прямое подтверждение того, что мы показали с помощью корреляции осадков на местах зимовок в Африке и сроков прибытия птиц на места размножения.
