Size Comparison
Habitat Comparison
Northern Fulmar
Open ocean and sea cliffs. Breeds on cliff ledges and grassy slopes on northern coastlines. Pelagic outside breeding season.
Roseate Spoonbill
Shallow coastal lagoons, estuaries, mangroves, and freshwater marshes. Nests in colonies in trees and shrubs.
Song & Call Comparison
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.
Roseate Spoonbill
Low, grunting and guttural croaking sounds at nesting colonies. Generally quiet. Alarm calls are softer croaks. Vocalizations lack melodic quality; purely functional colony sounds.
Geographic Range & Migration
Northern Fulmar
North Atlantic and North Pacific oceans. Breeds from the Arctic south to Britain, France, and New England.
Roseate Spoonbill
Southeastern United States, Caribbean, Mexico, Central America, and South America to Argentina.

How to Tell Them Apart
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
Roseate Spoonbill
Vivid pink body plumage with darker carmine on the wings. Bare greenish-grey head. White neck and back. Intensity of pink depends on diet.
Long, flat, spatulate greyish bill used for sweeping through shallow water
About These Birds
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.
Roseate Spoonbill
The roseate spoonbill is the only spoonbill species in the Americas and one of the most striking wading birds in the Western Hemisphere. Like flamingos, their pink color comes from carotenoid pigments in their crustacean prey. Nearly hunted to extinction for their plumes in the 19th century, they have recovered substantially.
