Definition
A 'guillemot' is a type of seabird belonging to the auk family (Alcidae), particularly within the genus *Cepphus* and *Uria*. They are known for their slender bodies, pointed bills, and excellent diving skills. Think of them as the sleek, torpedo-shaped divers of the bird world. Guillemots typically nest in large colonies on rocky cliffs. They are important members of marine ecosystems, feeding on fish and crustaceans.
