Many birds are able to change their egg-laying date to cope with variable conditions, new research shows.

The study examined birds and mammals, and found birds in particular showed the ability to find the “optimum” laying date.

However, the research team – led by the University of Montpellier – say this ability may not be able to keep pace with the current rate of climate change.

“The environment is constantly changing, creating variation in natural selection acting on populations,” said Dr Simon Evans, of the universities of Exeter and Oxford. MORE
