Grauer's Broadbill

Pseudocalyptomena graueri

A unique dumpy green flycatcher-like broadbill with a buffy crown, a black eye-stripe, and a powder-blue throat and vent. Juvenile duller. A scarce resident found singly and in pairs in the lower canopy and at middle levels of primary Albertine Rift Forest between 1760 and 2500 meters of elevation, preferring the edges of clearings. Highly localized, occurring in two isolated populations in Bwindi (Uganda) and Itombwe/Kahuzi (Democratic Republic of Congo), and inexplicably absent from ideal intervening habitat. May join flocks, but inconspicuous unless calling its soft high-pitched tinny “tsit-tsit,” repeated multiple times, and a rapid “tseet-tsit-tsit-sit-sit-it-it” in flight. 

识别特征

It is bright green with a blue throat and vent and a small bill, quite unlike those of other broadbill species. Adults have finely black-streaked buff crowns and narrow black eyestripes.
