For those who can’t get enough of bird migrations, the Guardian shows the paths for three species: Desertas petrel, Nightingale, and Bewick’s swan. Patterns are changing with climate. On Bewick’s swans:
As Europe warms, Bewick’s swans are making much shorter journeys to ice-free wetlands and agricultural areas in the Netherlands, Germany, Denmark and Poland – known as short-stopping. Britain has lost an estimated 43% of its Bewick’s swans in five years.
About 60 swans are carrying GPS collars on their necks. Tracking data shows that swans adjust their autumn journeys on a daily basis. On colder days, the birds travel bigger distances but if it is warm, they sometimes do not move at all.
That seems not good. At least we can appreciate the illustrations.
