Chuuk birds

Noddies, terns and boobies over the lagoon between dives, and the land birds found only in Chuuk, from the black-and-white Chuuk monarch to a white-eye that lives on a single mountaintop.

Seabirds and shore birds

Over the lagoon, on the islets and the reef flats

More than 100 bird species are on the Chuuk checklist, most of them seabirds and migrant shorebirds (Avibase). These are the ones most likely to be seen between dives. Pacific golden plovers and ruddy turnstones turn up on the hotel lawns of Weno, and wandering tattlers on the shores of Dublon (Birdquest 2024).

Found nowhere else

Land birds of the high islands

Ashore on Weno, Dublon and Tol

Chuuk is part of the East Caroline Islands Endemic Bird Area, and its native forest survives only in small patches on the higher reaches of a few islands (BirdLife). Three birds live only in Chuuk (Avibase): the Chuuk monarch, the Chuuk flycatcher and the teardrop white-eye, which is found only on one mountaintop on Tol (Wikipedia). No photos yet on this page; each card links to photos online.

Chuuk monarch Metabolus rugensis

Key marks: A large monarch flycatcher, about 20 cm. Males are almost all white with a black face and throat; females are all black. Both have a pale blue bill (Wikipedia).

At Chuuk: Found only in Chuuk; Endangered, because of the loss of its forest (Wikipedia). A birding group had a singing, displaying pair on Dublon in April 2024 (Birdquest 2024).

Teardrop white-eye Rukia ruki

Key marks: A white-eye of 14–15 cm (Oiseaux.net).

At Chuuk: Found only on the summit of Mount Winipot on Tol, in montane rainforest dominated by the endemic Chuuk poisontree; Endangered (Wikipedia). The largest remaining forest in Chuuk, 0.68 km², is on Tol (BirdLife). Reaching it means a hard climb with a local guide (Birdquest 2024).

Micronesian myzomela Myzomela rubratra

Key marks: A small honeyeater, about 13 cm. Males are scarlet with black lores; females are duller, black or brown with red patches (Wikipedia).
