Chestnut-hooded Laughingthrush (Pterorhinus treacheri)

About the Chestnut-hooded Laughingthrush

The chestnut-hooded laughingthrush (Pterorhinus treacheri) is a species of bird in the laughingthrush family Leiothrichidae endemic to Borneo. Described by the British ornithologist Richard Bowdler Sharpe as a distinct species in 1879, it was subsequently considered a subspecies of the chestnut-capped laughingthrush until 2007, when it was again raised to species status by the ornithologists Nigel Collar and Craig Robson. It is 22–24 cm (8.7–9.4 in) long, with a chestnut brown head and chin, with grey feathering on the top of the head. The upperparts and the side of the neck are slaty-grey, with a long white wing patch. The throat, breast, and upper belly are dull yellowish-brown, with purer grey flanks and a reddish-brown vent, lower belly, and thighs. It has a yellow half eye-ring behind and below the eye, while the tail has a blackish tip. Both sexes look similar, while juveniles are duller than adults.
