Cerulean Flycatcher

Eutrichomyias rowleyi

An unmistakable, fairly large blue flycatcher confined to Sangihe island. Entirely pale blue, with a paler belly and a conspicuous white eye-ring which is the most striking identification feature. Juveniles are gray-brown on the head and gray underneath, lacking blue. Singles and pairs can be found in forest understory, particularly where there are steep-sided valleys and streams. Joins mixed-species flocks. Most regular call is a “chew-chew-CHEW-CHEW-CHEW,” louder at the end. Also gives single “tuk” notes.

分类信息

The scientific name commemorates the British explorer and ornithologist George Dawson Rowley. The cerulean flycatcher was originally described in the genus Zeocephus, and until recently was known as the cerulean paradise-flycatcher. Alternate names include Rowley's flycatcher and Rowley's paradise-flycatcher. Although initially classified in Monarchidae, a 2017 study involving sequencing of DNA from the type specimen found that it was a member of the fantail family Rhipiduridae, being classified in the basal subfamily Lamproliinae (sometimes considered a distinct family) along with Chaetorhynchus and Lamprolia. This finding was accepted by the IOC, who renamed the species from "cerulean paradise-flycatcher" to just "cerulean flycatcher".

分布与栖息地

The cerulean flycatcher is endemic to the island of Sangihe, off North Sulawesi in Indonesia. Previously known only from a single specimen collected in 1873, this rare bird was rediscovered in October 1998 around forested valleys of Mount Sahendaruman in southern Sangihe.

Its diet consists mainly of insects and other small invertebrates.<p>Due to ongoing habitat loss, a small population size, and limited range, the cerulean flycatcher is evaluated as Critically Endangered on the IUCN Red List of Threatened Species.

Southern Variable Pitohui

Southern Variable Pitohui

Pitohui uropygialis

A fairly large bird of mainly secondary lowland and foothill forest edge. As the name suggests, a variably plumaged bird. Males mostly have a black hood, wing and tail with belly and back, chestnut or orange-brown. Males and females of some races have a brown head. Very similar to Hooded Pitohui, but Southern Variable is usually found at lower elevation and has black rather than brown above the base of the tail. Song, a varied, jumbled warble.

Fiscal Flycatcher

Fiscal Flycatcher

Sigelus silens

A large pied flycatcher that is most commonly mistaken for Southern Fiscal. However, the upright stance and slender unhooked bill are distinctive flycatcher traits, and the pattern of white in the flight feathers and basal windows of the tail is diagnostic. The female is duller than the male. Singles and pairs frequent a variety of open country habitats, including gardens, parks, shrubland, and woodland, where they perch conspicuously and hawk insect prey from the ground or aerially. The species is mostly silent but occasionally it utters a thin high-pitched song. The similar Southern Fiscal is more robust than the Fiscal Flycatcher, with a chunky hook-tipped bill, a white V-pattern on the shoulders, and a long tail with white outer feathers.

White-throated Swift

White-throated Swift

Aeronautes saxatalis

The only swift in U.S. and Canada that is not all-dark; white throat, breast, and patches on sides of rump are unique. Longer tail than Vaux's Swift. Narrower wings and different flight style than swallows. Found most commonly around rocky cliffs in deserts; ventures more extensively during nonbreeding season. Listen for its descending series of harsh, screeching notes.
