Sooretama Slaty-Antshrike Thamnophilus ambiguus

Sections

The Sooretama Slaty-Antshrike is a fairly common endemic of coastal eastern Brazil, where it occurs in the understory and midstory of lowland evergreen forest and its edges, as well as in sandy-soil woodland and tall scrub, from the state of Sergipe south to at least Rio de Janeiro. Most easily detected by virtue of its accelerating loudsong, which sounds similar to that of the almost wholly allopatrically distributed Planalto Slaty-Antshrike (Thamnophilus pelzelni); the latter replaces the present species over the interior of eastern Brazil. These two species differ only subtly in plumage too, but there is no suggestion of intergradation between them in their contact zone, in parts of Bahia and probably Minas Gerais. The behavior of the Sooretama Slaty-Antshrike apparently closely recalls that of other slaty-antshrikes. This antshrike takes its unusual vernacular name from the famous Sooretama Biological Reserve, which serves as an important focal point for the conservation of lowland east Brazilian avifauna, and wherein the present species is easily found.
