Thick-knees

Thick-knees are crow-sized birds, related to waders and bustards, most of which live in dry places (but some live on river and lake sides and on coastal beaches).

One species in the UK and Europe, but a few others in Australasia, south-east Asia, Africa and South America. They share features including large, bulging eyes (useful at dawn and dusk when they are most active), rather short, stout, pointed bills and strong yellow legs. They are noisy birds at dusk.
