Lanceolated Monklet

The lanceolated monklet is 13 to 15 cm (5.1 to 5.9 in) long and weighs 19 to 22 g (0.67 to 0.78 oz). It is entirely warm brown with scale-like buffy markings above. It has white bristles around the base of the large bill, and white "whiskers", which are actually tufts of feathers. Its lores and a half ring behind the eye are white. The wings and the top side of the tail are dark brown and the tail's underside is gray. Most of its underparts are white with heavy black streaks; the center of the belly is unstreaked and the vent area has an ochre tinge.

The lanceolated monklet is found in several disjunct areas. One is the Caribbean slope in Costa Rica and into west central Panama. Another extends from west central Colombia south to west central Ecuador. The largest area includes eastern Ecuador, southern Colombia, western Brazil, and eastern Peru. It is also found in a few locations in Bolivia. It inhabits a variety of landscapes including the edges and natural clearings of primary and mature secondary forest, small forest patches, shade coffee plantations, and lowland and montane evergreen forest. It tends to occur in the mid- and upper vegetation levels. In elevation it mostly occurs between 300 and 1,500 m (980 and 4,900 ft) but can be found as high as 2,100 m (6,900 ft).

The lanceolated monklet hunts from a perch, typically 4 to 8 m (13 to 26 ft) above the ground, and sallies from it for its insect prey. Its diet also includes berries. It sometimes follows mixed-species foraging flocks.
