Yellow-billed tropicbird

The White-tailed Tropicbird breeds on tropical islands laying a single egg directly onto the ground or a cliff ledge. It disperses widely across the oceans when not breeding, and sometimes wanders far. It feeds on fish and squid, caught by surface plunging, but this species is a poor swimmer. The call is a high screamed keee-keee-krrrt-krrt-krrt.

The Yellow-billed tropicbird is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

single record of the Yellow-billed Tropicbird (Phaethon lepturus catesbyi) listed from Gettysburg, Pennsylvania, there may be added an additional record from that state. A female of this tropical form was recovered at Nanticoke, Luzerne County, on 16 October 1954, by Mr. David M. Christian. The specimen is now no. 457964 in the collection of the U.S. National Museum.-GoRa^ M. Boa,m, U.S. National Museum, Washington 25, D.C. More

the Yellow-billed Tropicbird (Phaethon lepturus), the Red-billed Tropic- bird (Phaethon aethereus), and the Red-tailed Tropicbird (Phaethon rubri- cauda) (Peters, 1931). There are five recognized subspecies of Phaethon rubrlcauda (rubricauda, westralis, roseotlncta, melanorhynchos, and roths- childi). The subspecies rothschildi from the Hawaiian Island chain was described by Mathews (1915) from 13 specimens from Laysan and Niihau in the Leeward Hawaiian Islands. More

known as the Yellow-billed Tropicbird, which co-exists with the Red-billed Tropicbird on Ascension where it is approximately twice as abundant as its larger relative. It has been observed that the moulting of the flight feathers of Ascension’s sea birds and breeding rarely occur at the same time. This is most probably due to the nutritional requirements of replacing feathers and the decreased flight efficiency during moulting. More

Yellow-billed tropicbird Phaethon lepturus & red-billed tropicbird Phaethon aethereus Globally there are three species of tropicbird, all of which have tropical distributions.

YELLOW-BILLED TROPICBIRD Phaethon lepturus The three species of tropicbird all have tropical distributions. Two species are found in the tropical Atlantic and both breed on Ascension Island, with the majority of both species breeding on Boatswainbird Island. The most numerous is the Yellow-billed Tropicbird, or Boatswainbird (so called because its call is likened to that of a Bosun's whistle) after which the island was named. More

of Yellow-billed tropicbirds and 500 pairs of Red-billed Tropicbirds breed on Ascension. The Yellow-billed Tropicbird can be separated from the Red-billed Tropicbird by several characteristics: - the bill colour, if it can be seen, is a giveaway - the Yellow-billed Tropicbird has two thick, black, bars on each wing, while the inner wing of the Red-billed Tropicbird is finely barred black. - the Yellow-billed Tropicbird is a smaller bird than the Red-billed Tropicbird.

Longtail (Bermuda), Bosun Bird, Yellow-billed Tropicbird, Phaéton à bec jaune (French), Rabijunco cola blanca (Spanish) Systematics The White-tailed Tropicbird is the smallest, most common and most widely distributed of the three species of Phaethon. Five subspecies of Phaethon lepturus are recognized, two of which occur in the Atlantic. Wing length, size, patterns of black in the primaries, and bill color are the main characters used to separate subspecies. P. l. More
