Abstract

A skull deformity resulting in death of a herring gull chick (Larus argentatus) is described in detail. The bones of the skull and upper jaw were twisted, assymetrical and of unusual size or absent. The lower jaw had an almost “spoon-like” external appearance and lacked normal articular surfaces.
