Many of the most common species of migratory birds including nightingales, willow warblers and yellow wagtails are already spending an extra two months in Europe each migration season.
A study by experts at Durham University published in Global Change Biology has examined 50 years of bird-sighting data from the Gambia and Gibraltar.
It found that by arriving at migration destinations later in the autumn and leaving earlier in the spring, trans-Saharan migratory birds are spending an average of 50-60 more days a year in Europe.
