Orange-fronted Plushcrown
Metopothrix aurantiaca
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. Voice: The orange-fronted plushcrown's song is a descending series of three to five high thin notes. Its call is a thin "tsweet-tsweet".

Rusty-winged Barbtail
Premnornis guttuliger
The rusty-winged barbtail is 13 to 14.5 cm (5.1 to 5.7 in) long and weighs 13 to 17 g (0.46 to 0.60 oz). The sexes' plumages are alike. Adults of the nominate subspecies have a pale buffish or brownish buff supercilium and a dark brown stripe behind the eye; the rest of their face is streaked brown and buff. Their crown is dark olive-brown with a faint scallop pattern. The sides of their neck and upper back are brownish with pale buff spots, their lower back is browner and unspotted, their rump is brown with a faint rufescent tinge, and their uppertail coverts are chestnut. Voice: The rusty-winged barbtail is seldom vocal. What is thought to be its song is a fast, accelerating, "'tsi-tsi-tsi-si-si-sisisisisisi". Its call is described as a sharp "tseep" or "tsip" that sometimes runs into a series.
