Description
The blue-bearded helmetcrest is about 11.5 cm (4.5 in) long. It has a short straight bill. The male has a long black and white crest and a mostly dusky face with a buffy-white "collar". Its upperparts are olive green. Its throat has a thin white "beard" with a purplish blue center stripe. The rest of the underparts are dingy buff with olive spots that blends to buffy white on the undertail coverts. The tail is moderately long and forked. The upper side of the central tail feathers is bronzy olive and the rest are white with reddish bronze fringes and tips, and the underside is cream with wide olive tips. The adult female is similar to the male but lacks the crest and beard, is overall duller, and has a white throat. Juveniles resemble the adult female but without the white throat.[6]

The blue-bearded helmetcrest is found only in the isolated Sierra Nevada de Santa Marta of northern Colombia. It inhabits páramo grasslands at elevations between 3,000 and 4,800 m (9,800 and 15,700 ft).[6]
