Habitat Comparison
Blue Jay
Deciduous and mixed forests, parks, and suburban areas. Highly adaptable to human-modified landscapes.
Northern Gannet
Open ocean and coastal waters. Breeds in dense colonies on steep rocky islands and sea stacks.
Song & Call Comparison
Blue Jay
A harsh, ringing 'jaay-jaay-jaay'. Also mimics Red-tailed Hawk and other species convincingly. Gives soft, liquid 'bell' calls and gurgling whispers in flocks.
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
Blue Jay
Eastern and central North America from southern Canada to the Gulf Coast. Some populations migrate irregularly.
Northern Gannet
North Atlantic, breeding from Newfoundland and Gulf of St. Lawrence to Norway, Iceland, and Britain. Winters at sea south to the tropics.

About These Birds
Blue Jay
어치는 화려한 깃털과 큰 울음소리로 알려진 까마귀과의 대담하고 지능적인 구성원입니다. 가을마다 수천 개의 도토리를 저장하기 때문에 참나무 나무의 중요한 산포자입니다. 복잡한 사회 행동으로 먹이통에서 다른 새들을 겁주기 위해 매의 울음소리를 흉내 내기도 합니다.
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.
