Size Comparison
Habitat Comparison
Hawfinch
Deciduous and mixed woodland, orchards, parks, and large gardens with mature fruiting trees.
Northern Gannet
Open ocean and coastal waters. Breeds in dense colonies on steep rocky islands and sea stacks.
Song & Call Comparison
Hawfinch
A sharp, metallic 'tsick' call — the primary vocalization and often all that's heard. Song is a thin, reedy warble. Generally inconspicuous vocally despite its striking appearance.
Northern Gannet
Loud, harsh 'urrah-urrah' grunting and croaking at breeding colonies on sea stacks. Also gives a softer 'karrr' in flight. Large colonies are extremely noisy during the breeding season.
Geographic Range & Migration
Hawfinch
Europe, North Africa, and western and central Asia. Partially migratory, with northern populations moving south in winter.
Northern Gannet
North Atlantic, breeding from Newfoundland and Gulf of St. Lawrence to Norway, Iceland, and Britain. Winters at sea south to the tropics.

How to Tell Them Apart
Hawfinch
Orange-brown head with a black bib and eye stripe. Warm brown back, grey nape, and broad white wing bar. Massive head and bill give a top-heavy appearance.
Enormously powerful, conical, pale bill capable of cracking cherry and olive stones
Northern Gannet
Brilliant white body with black wingtips and a golden-yellow wash on the head and nape. Blue-grey bill with dark lines and pale blue eye-ring.
Long, straight, pointed, pale blue-grey bill with serrated edges
About These Birds
Hawfinch
The hawfinch possesses the most powerful bill relative to body size of any European bird, capable of cracking cherry stones that require a force of 27-43 kg. Despite its distinctive appearance, it is famously shy and difficult to observe. The skull contains special adaptations to absorb the enormous forces generated during seed-cracking.
Northern Gannet
The northern gannet is a spectacular plunge-diver, folding its two-meter wingspan into an arrow shape to hit the water at up to 100 km/h. Air sacs under the skin and a reinforced skull protect it from the impact. Bass Rock in Scotland hosts over 150,000 gannets, the largest single colony of any seabird in the world.
