White-fringed Antwren (Formicivora grisea)
|
 |
Brazil The White-fringed Antwren is found from Colombia through the Orinoco Basin and into the coastal areas of the Guianas, in the Amazon Basin south of the river Amazon and along coastal eastern Brazil south to Rio de Janeiro.
|
 |
It inhabits similar but denser scrubby habitats as its congener, the Rusty-backed Antwren (F. rufa). Like the Rusty-backed, it is usually seen in pairs gleaning on leaves. It is relatively confiding but may be difficult to see given the dense nature of its habitat. |
 |
The male has greyish-brown upperparts with a blacker tail showing broad white tips. It has a white supercilium, a bold white wing-bar and white spots on the wing-coverts. Below, it is mainly black with a broad white strip extending from the supercilium along the sides and flanks. The male in the second photo is moulting its tail feathers. |
 |
The female is generally browner but there are a variety of plumage patterns which is one factor leading to the belief that more than one species may be involved. Photo 4 is a female of the nominate sub-species F. g. grisea. There are illustrations in Ridgely & Tudor, Volume 2, Plate 20 and in Hilty & Brown, Plate 28. |
