Common Kingfisher
Clear, slow-flowing rivers, streams, lakes, and ponds with suitable perching and nesting banks. Requires clean water with good fish populations.
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 Kingfisher
A sharp, penetrating 'chee' whistle given in flight, often the first indication of its presence. Short, shrill single note as it darts low over rivers. Contact call is a rippling …
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

Long, straight, dagger-like dark bill — orange base on the lower mandible in females
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 Kingfisher
The common kingfisher is a dazzling jewel of waterways, its iridescent blue plumage caused by light refraction in the feather structure rather than pigment. These birds inspired the design of the Shinkansen bullet train in Japan — the shape of their bill was copied to reduce sonic booms when trains exit tunnels.
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.
