Newly discovered birds in the 2000
Caatinga Antwren (Herpsilochmus sellowi)

This species is an inhabitant of the caatinga, especially mid-humid patches of semideciduous woodland and scrub. It forages predominantly in the middle and upper tree levels, especially where papilionaceous shrubs are present. Individuals of Caatinga Antwren have been known for a long time, but differences were not recognized so they belonged to H. pileatus, the Bahia Antwren. (That species is now considered to be a coastal Bahia endemic. It has atricapillus as closest relative species.) Sellowi has a shorter and narrower bill, pale loral area, short postocular streak, and undertail coverts variably buffy. The female lacks distinct white marks in the crown, but may have buffy feather tips there. Another distinction can be found in the (loud)song: a 2.3 seconds series of notes like that of pileatus, but with twice as many notes, at an even, double pace and slightly higher in pitch.

Foothill Elaenia (Myiopagis olallai)

A new species of New World flycatcher in the genus Myiopagis (Aves, Tyrannidae, Elaeniinae) is described from Andean submontane forest of eastern Ecuador and eastern Peru. It appears to be most closely related to M. caniceps of lower elevations and more distantly to M. gaimardii, with which it is syntopic. (Coopmans P, Krabbe N (2000) A NEW SPECIES OF FLYCATCHER (TYRANNIDAE: MYIOPAGIS) FROM EASTERN ECUADOR AND EASTERN PERU. The Wilson Bulletin: Vol. 112, No. 3 pp. 305-312).
Taiwan Bush-warbler (Bradypterus alishanensis)

A medium-sized, dark brown bush warbler with short, round wings and a longish, broad, graduated tail. Entire upperparts, including head, olive-brown with a rufous tinge; tail more olive. Indistinct and narrow buffy supercilium. Chin and throat white, streaked with black; the rest of the underparts white, washed gray on sides of neck and olive-brown on sides of breast and belly. Flight feathers and tail marginally darker brown than rest of upperparts. Whitish tips of undertail coverts give scaly appearance. Sexes similar. Iris, brown. Bill, black above, pinkish below. Confined to central mountains at 500 – 3,000 m where it is common in cold-temperate bamboo thickets and temperate coniferous forest edges. Inhabits low scrub, weeds and thick grass in mountain regions. Found mostly singly or in pairs. Mostly ground-dwelling; keeps low in dense scrub. Food is mainly insects. Breeding season is from May to July. Nest usually placed in tall grass. Clutch size: 2 eggs. (Rasmussen, P.C.; Round, P.D.; Dickinson, E.C. & Rozendaal, F.G. (2000) A new bush-warbler (Sylviidae, Bradypterus) from Taiwan The Auk 117: 279-289 ).
Scarlet-banded Barbet (Capito wallacei)

19 cm. Very striking, recently discovered barbet. Cap and nape scarlet. Broad white supercilium starting from just in front of eye. Black lores, area below eye and ear-coverts. Scapulars mostly black (yellow “V” in female). Back yellow, large white rump and black tail. Throat and upper breast white, bordered below by a broad scarlet band. Lower breast and belly bright yellow, fading to yellowish-white in undertail coverts. The species is known only from on, or near, the summit of one mountain, where a relatively flat plateau is cloaked in cloud forest between 1,200 and 1,540 m. Epiphytes, especially bryopytes, bromeliads and orchids, cover most of the trunks and large branches of the short trees (10-20 m). The predominant trees near the summit are melastomes and clusias. The forest floor has a deep (up to 1 m) spongy cover of mosses intermixed with leaf litter and soil. The wet, epiphyte-covered montane forest changes abruptly to taller and drier subtropical forest below 1,250 m. There is little human habitation in the watershed, and none above 300 m. Only a small amount of hunting is conducted by infrequent visitors. However, deforestation is extensive on the west slope of the adjacent Cordillera Azul, especially in the drainage of the RÃo Biabo.
