Nightingales at risk due to shorter wings caused by climate crisis

Migration to European breeding grounds from Africa is harder due to evolutionary changes

The nightingale was feted by John Keats as a "light-winged Dryad of the trees". But the much-celebrated small bird with a beautiful song may be increasingly endangered because its wings are getting shorter.

The nightingale makes an epic journey from sub-Saharan Africa to breed in Europe each summer but there are barely 7,000 nesting pairs left in England.
