White-tailed Tropicbird

White-tailed Tropicbird: A large bird, white with long black bar on upperwing coverts, outer primaries. Black loral mask which extends through and past eye. Bill is yellow to orange. Tail streamers are white and can be up to seventeen inches long. Legs and feet are yellowish, black webbing on toes.

● Song: "keek-keck", "eeh-oh", "squawk"

● Foraging & Feeding: White-tailed Tropicbird: This bird is pelagic and only comes ashore to breed. It eats small, surface-dwelling pelagic fish and squid by making deep vertical plunge dives into water from air for prey, catching it in its bill, and then swallowing it under water or on surface. It does not follow boats but may express interest in them as flying fish are frequently flushed into flight by moving boats therefore providing easy prey.

● Breeding & nesting: White-tailed Tropicbird: A single white to pale buff egg with brown and purple spots is laid on the ground in ridges of cliffs, crevices, caves, or sheltered by grasses or bush. Incubation ranges from 40 to 42 days and is carried out by both sexes. Both parents care for and feed young.

● Similar species: White-tailed Tropicbird: Adult Red-billed Tropicbird is larger with a slower wingbeat and lacks black patches on upperwing. Immature Red-billed has less distinct barring on the back. Adult Red-tailed Tropicbird also lacks the black patches on the upperwing.

Flight Pattern

Buoyant graceful pigeonlike flight with fluttering wing strokes alternated with soaring glides., Hovers briefly over prey or perch before dipping down to it.

● Range & Habitat: White-tailed Tropicbird: Occurs regularly off the coast of the southeastern United States and less commonly throughout the northern and eastern Gulf of Mexico and tropical eastern Atlantic and Indian Oceans. It originates from breeding colonies in Bermuda, the Bahamas, and the Greater and Lesser Antilles. There are three records of this bird in western North America (southern California and Arizona). Nest sites range from closed-canopy rain forest to barren ground.

4 and 6 letter alpha codes

The four letter common name alpha code is is derived from the first two letters of the common first name and the first two letters of common last name. The six letter species name alpha code is derived from the first three letters of the scientific name (genus) and the first three letters of the scientific name (species). See (1) below for the rules used to create the codes..

Four-letter (for English common names) and six-letter (for scientific names) species alpha codes were developed by Pyle and DeSante (2003, North American Bird-Bander 28:64-79) to reflect A.O.U. taxonomy and nomenclature (A.O.U. 1998) as modified by Supplements 42 (Auk 117:847-858, 2000) and 43 (Auk 119:897-906, 2002). The list has been updated by Pyle and DeSante to reflect changes reported by the A.O.U from 2003 through 2006.
