Orange-fronted Plushcrown

The orange-fronted plushcrown is 11 to 12 cm (4.3 to 4.7 in) long and weighs 10 to 12 g (0.35 to 0.42 oz). The sexes have the same plumage. Adults have an orange forehead ("front") and yellow lores, eyering, and supercilium; the last becomes greenish yellow behind the eye. They have a faint greenish olive line through the eye and greenish olive ear coverts. Their crown, back, rump, and tail are greenish olive, with the rump being somewhat paler. The "plush" of the crown is usually not apparent in the field. Their wings are dark olive fuscous with pale yellow edges on the coverts and flight feathers. Their throat is yellow and the rest of their underparts are dull yellowish green that is slightly paler on the belly. Their iris is brown to dark brown to gray, their maxilla black, their mandible black to gray, and their legs and feet bright yellow-orange to yellow. Juveniles have little or no orange and yellow on their face. It is the only species of furnariid with yellow/greenish plumage and yellow legs, in which it resembles a tanager or warbler.

The orange-fronted plushcrown is found in southeastern Colombia's Putumayo and Amazonas departments, eastern Ecuador and Peru, Beni Department in northeastern Bolivia, and from them into western Brazil east to the lower Juruá and upper Purus rivers. It inhabits forest along rivers and islands in them, mature secondary forest, and the edges of clearings in várzea and terra firme forest. It is seldom far from a river. In elevation it generally ranges from 150 to 650 m (490 to 2,100 ft); in Colombia it reaches only 500 m (1,600 ft).

The orange-fronted plushcrown feeds mostly on arthropods and has once been observed feeding on fruit. It typically forages in pairs or small groups that are thought to be families, and occasionally joins mixed-species feeding flocks. It usually forages from the forest's mid-storey to its canopy, gleaning prey from leaves and twigs often by hanging acrobatically from them.
