Size Comparison
Habitat Comparison
Common Raven
Diverse habitats from Arctic tundra to deserts, mountains, forests, and coastlines. Avoids dense urban areas but thrives near human activity.
Northern Fulmar
Open ocean and sea cliffs. Breeds on cliff ledges and grassy slopes on northern coastlines. Pelagic outside breeding season.
Song & Call Comparison
Common Raven
Highly varied: deep resonant 'kraa-kraa-kraa', hollow 'tok-tok', liquid 'klonk', and wing-whooshing. Among the most intelligent corvid callers; uses calls contextually in groups.
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.
Geographic Range & Migration
Common Raven
Holarctic distribution across North America, Europe, Asia, and North Africa. The most widely distributed corvid.
Northern Fulmar
North Atlantic and North Pacific oceans. Breeds from the Arctic south to Britain, France, and New England.

How to Tell Them Apart

All black with a glossy purplish-blue iridescent sheen. Shaggy throat hackles, long wedge-shaped tail, and large robust build distinguish it from crows.
Large, powerful, curved black bill
Northern Fulmar
Light morph: white head and underparts with grey wings and back. Dark morph: entirely grey. Tube-nosed bill and stiff-winged flight distinctive at sea.
Yellowish hooked bill with prominent tubular nostrils on top
About These Birds
Common Raven
The common raven is among the most intelligent birds, demonstrating tool use, future planning, and social manipulation in scientific studies. In many cultures, ravens feature prominently in mythology as creators, tricksters, or messengers. Their complex vocalizations include over 30 distinct calls.
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.
