Researchers in Switzerland have found that
bird species which migrate short distances may be benefitting from climate change prolonging the feeding + breeding conditions that suit them.
Conversely,
bird species which migrate long distances may be becoming increasingly threatened by climate change.
This is because climate change appears to be altering the weather conditions wide-ranging birds encounter
before, during + after their migration. With some species no longer being as well adapted to, or synchronised with, the conditions they encounter during their travels as they once were and thus breeding less successfully...
