The cerulean flycatcher (Eutrichomyias rowleyi) is a medium-sized (up to 18 cm long), blue passerine with bright cerulean blue plumage, a bare white orbital ring, dark brown iris, bluish black bill and pale blue-grey below. The young has a shorter tail and grey underparts. It is the only member of the monotypic genus Eutrichomyias. Although it resembles a monarch flycatcher, it is actually related to the fantails.
Taxonomy and systematics[]
The scientific name commemorates the British explorer and ornithologist George Dawson Rowley. The cerulean flycatcher was originally described in the genus Zeocephus, and was known as the cerulean paradise-flycatcher. Alternate names include Cerulean flycatcher, 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.[2] This finding was accepted by the IOC, who renamed the species from "cerulean paradise-flycatcher" to just "cerulean flycatcher".[3]
Distribution and habitat[]
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.
Behaviour and ecology[]
Food and feeding[]
Its diet consists mainly of insects and other small invertebrates.
Threats[]
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.
