Серый бананоед Crinifer concolor

Unusual gray turaco with a long tail and towering crest. The flight is hesitant, and the tail flops up and down. Usually in small groups, which often perch up conspicuously on trees and bushes. The calls include a series of grumpy yelps, and the classic nasal “go-waaay” call. Similar in shape to other go-away-birds, but there is little overlap in range, and easily separated by the uniformly gray coloration.
