Common Starling
Open countryside, farmland, parks, and urban areas. Forms enormous communal roosts in winter, especially in urban environments.
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 Starling
A complex mimic: rattles, whistles, clicks, and squeaks mixed with imitations of other birds. Song is a continuous medley. Also gives harsh 'scheer' alarm and chattering.
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 Starling
Native to Europe, western Asia, and North Africa. Introduced to North America, South Africa, Australia, and New Zealand.
Northern Fulmar
North Atlantic and North Pacific oceans. Breeds from the Arctic south to Britain, France, and New England.

About These Birds
Common Starling
The common starling is famous for its murmurations — vast swirling flocks of thousands that create mesmerizing patterns in winter skies. An accomplished mimic, it can imitate other birds, car alarms, and phone ringtones. Introduced to North America by a group intent on establishing every bird mentioned by Shakespeare.
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.
