Big Garden Beak Watch

Beak deformities in wild birds are unusual, with fewer than one in 200 adult birds thought to be affected. However, a number of reports from BTO Garden BirdWatchers have caught our eye and we are keen to find out more about the deformities being seen in British and Irish gardens.
