Grey Silky-flycatcher

Ptiliogonys cinereus

Small34 gForest

The grey silky-flycatcher is 18.5 to 21 cm (7.3 to 8.3 in) long. It is a slender bird with a prominent crest and a long tail. Adult males of the nominate subspecies P. c. cinereus have dusky lores, a white patch above the lores, a thin white eye-ring, and a white or brownish white chin and cheeks on an otherwise blue-gray head and crest. Their upperparts are blue-gray. Their flight feathers are black. Their central pair of tail feathers are black and the rest have a black base, a white upper half, and black lower half. Voice: The grey silky-flycatcher's song is "a warbled series of chuck notes, high seep notes and quiet whistles". It also makes a loud "tu whip, tu whip" whose second note is higher-pitched and more emphatic, a "dry chi-che-rup che-chep", a "nasal k-lik", and a "rattling note in flight".
