Characteristics: This species has a total length of 17 cm (measured from tip of bill to end of tail). This bird has a bull-headed look because of the crest-like plumage and has also a short tail. The bill is slightly hooked and the lower mandible is yellowish. The plumage is dark olive above, but we can distinguish that the wings and the tail are dark gray and the pale gray wing-bars that are fairly hard to see. Then, the throat and the underparts are whitish-yellow, with the sides of the body and the flanks more olive grayish colored. This olive coloration extends across the breast. We can also see a patch of white, extending from behind the wing onto the sides of the rump.
