Golden-fronted Greenlet

The golden-fronted greenlet is 11 to 12 cm (4.3 to 4.7 in) long and weighs an average of 9.5 g (0.34 oz). The sexes have the same plumage. Adults of the nominate subspecies have an ochre-olive forehead and a buffy brown crown. Their upperparts are greenish brown that is more yellowish green on the rump. Their wings' coverts are greenish brown and their primaries and secondaries are dull blackish gray with thin greenish edges on the outer webs. Their tail is dull olive-green. Their chin and throat are whitish buff, their breast grayish yellow, and their belly and vent yellowish. Subspecies P. a. saturata has more brightly colored underparts than the nominate, with a stronger buffy or ochraceous wash on the breast. P. a. helvina has a dark reddish brown crown; its upper breast is darker, its flanks greener, and its undertail coverts darker yellow than the nominate's. All subspecies have a brown or black iris, a dusky horn maxilla, a pinkish mandible, and grayish brown or plumbeous legs and feet.

The nominate subspecies of the golden-fronted greenlet is found from Coclé Province in Panama east into northern Colombia. Subspecies P. a. helvina is found in northwestern Venezuela west of the Andes from Zulia east to southern Táchira and northern Mérida. P. a. saturata is found on Trinidad and from eastern Colombia across most of northern Venezuela. The species inhabits a variety of landscapes in the tropical zone including deciduous, gallery, and secondary forest, the edges of evergreen forest, dryer scrublands, and gardens. In elevation it ranges from sea level to 1,000 m (3,300 ft) in Colombia and to 1,900 m (6,200 ft) in Venezuela.

The golden-fronted greenlet's diet has not been fully examined but is known to include insects and spiders. It feeds actively at all levels of the forest, often hanging upside-down to glean prey from leaves. It usually forages in pairs or small family groups and frequently joins mixed-species feeding flocks.
