The northern gannet

Their beak is long, strong and conical with a slight downward curve at the end. The front part has a sharp edge. In adults, the beak is blue-grey with dark grey or black edges. It is brownish in immature birds. The northern gannet’s eyes are large and point forwards, they have a light blue to light grey iris surrounded by a thin black ring. The four toes of their feet are joined by a membrane that can vary from dark grey to dark brown. There are yellow lines running along the toes that continue along their legs, these lines probably have a role in mating. The rear toe is strong and faces inwards allowing the birds to firmly grip onto vertical cliff faces.
