They are almost entirely black, and have a conspicuous crest on top of their head, vaguely resembling an umbrella (hence their common name). All have an inflatable wattle on the neck which serves to amplify their loud, booming calls This wattle may reach a length of 35 cm (14 in) in the Long-wattled Umbrellabird, but is smaller in the two remaining species, and covered in bare, bright red skin in the Bare-necked Umbrellabird. Females resemble males, but are noticeably smaller and have a reduced crest and wattle.
Of the three species, two, the Long-wattled and Bare-necked Umbrellabird, are threatened by habitat loss and, to a lesser extent, hunting.
The Bare-necked Umbrellabird is the largest passerine in its range and is found in Costa Rica and Panama:
