Habitat Comparison
Northern Fulmar
Open ocean and sea cliffs. Breeds on cliff ledges and grassy slopes on northern coastlines. Pelagic outside breeding season.
Ruby-throated Hummingbird
Deciduous and mixed forests, woodland edges, gardens, and parks with flowering plants. Migrates across the Gulf of Mexico.
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.
Ruby-throated Hummingbird
Soft, high-pitched chattering and twittering 'chee-dit'. Also produces a thin 'tik' call in flight. Wing beats create an audible high-pitched humming buzz during hovering.

Ruby-throated Hummingbird
Metallic green upperparts and greyish-white underparts. Males have a brilliant iridescent ruby-red gorget that appears black in poor light. Females lack the gorget.

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.
Ruby-throated Hummingbird
The ruby-throated hummingbird is the only breeding hummingbird in eastern North America. These tiny birds beat their wings about 53 times per second and can fly backwards, sideways, and even briefly upside down. They make an extraordinary non-stop 800 km crossing of the Gulf of Mexico during migration.
