Hoary-throated Spinetail - Poecilurus kollari

Hoary-throated Spinetail (Poecilurus kollari)
(aka Rio Branco Spinetail, Synallaxis kollari)

Roraima, Brazil
July 2001

The Hoary-throated Spinetail has a very small range along the upper rio Branco and other rivers in the extreme north of Brazil and adjacent Guyana. It is known from only six sites and is currently classified as Endangered by Birdlife International.

Its habitat seems restricted to riverine forest with dense undergrowth and tangly vines although we did find one bird in rather more open, bushy vegetation overhanging marshland.

The only illustration found is in Threatened Birds of the World, Page 351.

However, the birds photographed here show some marked differences from this illustration particularly with regard to the distribution of brown and grey on the head.

We believe that the white tail feather on the bird in the first photo is probably due to a lack of pigmentation in the case of this individual.
