Prong-billed barbet

The prong-billed barbet (Semnornis frantzii) is a distinctive, relatively large-billed bird native to humid highland forest of Costa Rica and western Panama.

The prong-billed barbet is 17 to 18.5 cm (6.7 to 7.3 in) long and weighs about 60 to 70 g (2.1 to 2.5 oz). Its bill is silvery gray to bluish with a dark tip; a notch on the tip of the mandible provides its English name. The maxilla has a hooked tip and a notch on the side. Adults have a dull golden brown crown, brownish olive nape and upper back, and olive green lower back, rump, and uppertail coverts. Males have a glossy black tuft of feathers at the rear of the crown; females lack it. Both sexes have dull slaty black lores, cheeks, and chin. The sides of their head, their neck, and their upper breast are buffy olive that becomes yellowish on the lower breast. Their belly's center is pale yellow and their flanks dull grayish with a pale yellowish wash. Their tail is dull green and their wings dusky. Immatures are overall duller than adults and the black areas of the adult's face are grayer in immatures.
