White-tailed Tropicbird

Identification

The white-tailed tropicbird is a striking seabird that lives up to its name with predominantly white plumage and an unmistakable long tail. Adults measure 71–80 cm in length, but their extremely long central tail feathers effectively double their total length, making them appear far more elongated than their modest body size suggests. The wingspan ranges from 89–96 cm. Key identifying features include a distinctive black band across the inner wing, a black eye-mask, and an orange-yellow to orange-red bill. Males tend to have proportionally longer tail streamers than females. Juveniles are duller, lacking the elegant tail plumes, sporting a greenish-yellow bill instead, and displaying finely barred plumage on the back.

Range & Habitat

This is the smallest member of the tropicbird family and the only species found across multiple tropical ocean basins: the Atlantic, western Pacific, and Indian Oceans. The white-tailed tropicbird nests on tropical islands throughout its range, with populations extending as far north as Bermuda, where local residents affectionately call it the "longtail." Six recognized subspecies occupy different regions, including populations across the tropical Indian Ocean, the western Pacific, the Caribbean, and isolated island colonies at Ascension Island, Fernando de Noronha, Christmas Island, and Europa Island in the Mozambique Channel. While breeding is confined to islands, these birds disperse widely across open ocean when not nesting and are occasionally spotted far from their typical range.

Behaviour & Diet

White-tailed tropicbirds are specialist hunters that feed primarily on flying fish, squid, and crabs, typically hunting in pairs. They employ a dramatic hunting technique, diving from heights up to 20 meters to catch prey—a method similar to that of gannets. Flying fish are captured in mid-air, while other prey are caught at or near the water surface. The birds often hover above the ocean before swallowing their catch and taking off again. Despite their ocean-dwelling lifestyle, they are surprisingly poor swimmers. These birds breed on tropical islands, laying a single egg directly onto the ground or a cliff ledge, rather than building a nest. Unusually, they do not follow a yearly breeding cycle; instead, they can breed again just 5 months after an unsuccessful nesting attempt or 10 months after successfully raising a chick, depending on climate and site availability. Their distinctive call is a high, piercing screech: keee-keee-krrrt-krrt-krrt.

Best Time & Places to See It

White-tailed tropicbirds can be observed year-round in tropical ocean regions, though breeding seasons vary by location and individual breeding cycles. Birdwatchers and wildlife travelers should focus on tropical island breeding colonies, particularly in the Caribbean, Bermuda, and across the Indian and Pacific Oceans. The species has recently begun nesting on Little Tobago alongside red-billed tropicbirds, offering an opportunity to compare tropicbird species. Spotting them at sea requires patience and offshore travel, though their distinctive silhouette and white plumage make them relatively conspicuous when present.

Photography Tips

Photographers should look for this species hovering over clear tropical waters, where the white plumage and striking black wing markings create strong contrast. The dramatic plunge-diving behavior offers dynamic action shots. Approach slowly from a distance, as these birds can be wary. The long tail streamers are a signature feature—try to capture them fully extended in flight for the most compelling images. Early morning light often works best for highlighting the white plumage and orange-yellow bill details. Breeding colonies on islands provide excellent opportunities for close-range photography of perched birds, nesting behavior, and interactions between pairs.
