Migration is often not so obvious in the autumn as it is in spring with summer visitors ‘disappearing’ gradually, often without notice. Winter visitors tend to arrive over a longer time period and are not in such a rush as spring migrants; the urgency of the breeding season is not there. It’s a really exciting time though, with winter thrushes, flocks of geese and swans arriving and the dispersal of raptors to their wintering grounds.
Recording the departure dates of migrants is often considered more difficult than noting arrival dates. By submitting lists regularly to BirdTrack we will be able to get a clear picture of the timing and pattern of departure of summer visitors.
