Song & Call Comparison

An eerie, drawn-out rasping shriek 'shreeeeee' — not a hoot. Also gives hissing, snoring, and bill-snapping when disturbed. Chicks call with a persistent rasping hunger call.
Northern Fulmar
A nasal, cackling 'kak-kak-kak-kak' or grunting 'uh-uh-uh' at the nest and colony. Less melodic than petrels. In flight gives occasional single nasal calls.

About These Birds
Barn Owl
The barn owl has the most asymmetrical ears of any owl, giving it the finest auditory localization ability in the animal kingdom. It can catch prey in complete darkness using sound alone. The barn owl's distinctive heart-shaped face acts as a parabolic dish, funneling sound to its offset ears.
Northern Fulmar
The northern fulmar is a long-lived seabird that can survive over 40 years. It defends its nest by projectile-vomiting a foul-smelling stomach oil at intruders, which can mat the feathers of predators and cause fatal loss of waterproofing. Fulmars have expanded their breeding range dramatically southward over the past two centuries.
