|Yellow-browed Antwarbler Hypocnemis hypoxantha
(aka Yellow-browed Antbird) cantador-amarelo
|Cristalino Lodge, Mato Grosso,
The Yellow-browed Antwarbler is distributed in the western part of the Amazon Basin east to the rio Negro north of the Amazon and east to the upper Juruá south of the Amazon. There is a disjunct population (race ochraceiventris) between the Tapajós / Teles Pires and the rio Xingu. See the distribution map at Birdlife International.
|It is found mainly in lowland and foothill forest though ochraceiventris is sometimes found in more edge
habitats and bamboo patches.
It is superficially similar to Warbling Antbird H. cantator but has a yellow rather than white supercilium.
|This species was only discovered at Cristalino in 2004 and seems to be confined to a very small patch of rather open forest at the top of the Serra trail. One would expect it to belong to the sub-species H. h. ochreceiventris but I could find virtually no evidence of ochre on the flanks of the pair that we observed.|
|Note that the second bird, seen here in photos 4 and 5,
has almost no streaking on the breast. It also has a hint of pale pink around the gape so I think that it may be an immature bird.
