Northern Gannet
Morus bassanus
Large seabird of the Atlantic with long, pointed bill, wings, and tail. Adults bright white with cream-colored head and black wingtips. Takes several years to reach adult plumage; juveniles are all sooty-brown and slowly acquire more white as they mature. Nests in enormous colonies on cliffs in the North Atlantic. Spends most of its life at sea, although often fairly close to land, so they are often visible from shore or on whale watching boats. Dives torpedolike into the ocean for fish. Gathers in large feeding flocks, but sometimes solitary.

Bare-crowned Antbird
Gymnocichla nudiceps
Scarce and rather shy antbird of evergreen forest, second growth thickets, and overgrown plantations in humid tropical lowlands. Usually in pairs, on or near the ground, where often accompanies army ant swarms to capture prey flushed by the ants. Male is black with white wingbars with bright blue naked skin on crown and around eyes. Female is rusty brown overall with bright blue naked eyering.

Cuban Emerald
Riccordia ricordii
A pugnacious hummingbird that feeds on flowers and insects and is sometimes found flycatching. Inhabits a broad range of habitats. Often tame around humans. The long-tailed male is swathed entirely in iridescent green and has a distinctive red base to the bill, except for a white patch below the belly and a white spot behind the eye. The female is metallic green above, dingy white below, and has a relatively long, forked tail. The female Bee Hummingbird is much smaller, shorter billed, shorter tailed, and is iridescent turquoise above unlike the Cuban Emerald. Female Ruby-throated Hummingbirds have shorter, unforked tails with white on the tail tip. Vocalizations include a prolonged jumbled series of high-pitched squeaks and buzzes and a high-pitched but descending “tsee, tsee, tsee, tse, tse.”
