This species has an extremely small range confined to mixed tree-fern forest on one small island, where recent surveys have shown it to have an extremely small population. In 1859 Sclater, the famous zoologist wrote in the Ibis, the magazine of the British Ornithologists’ Union: “Oxyurus masafuerae seems to be restricted to the island of […]
Pale-breasted Spinetail (Synallaxis albescens) Science Article 1 abstract I recorded and analyzed vocalizations of Synallaxis albescens from three populations in Venezuela,two continental and one island, to assess the extent of geographic variation for a species of the familyFumariidae. Previous work on geographic variation in suboscines has focused on species of the Tyrannidae. Ialso tested the […]
Black-capped Foliage-gleaner (Philydor atricapillus) Science Article 1 abstract Twenty nine samples regurgitated from the dead-leaf specialist Black-capped Foliage-gleaner (Philydor atricapillus) after administration of tartar emetic were examined to assess the diet of the species. Similarly, samples of invertebrate fauna living in suspended dead-leaf clusters were obtained to estimate prey availability for the birds. Diet was […]
White-chinned Woodcreeper (Dendrocincla merula) Science Article 1 abstract Few studies have been conducted to verify how the structure of the forest affects the occurence and abundance of neotropical birds.Our research was undertaken between January 2002 and July 2004 at the Reserva Ducke, near Manaus (02
Straight-billed Woodcreeper (Xiphorhynchus picus) Science Article 1 abstract Among those few hypotheses amenable to falsification by phylogenetic methods concerning the diversification of the Amazonian biota, three can be singled out because of their verifiable predictions: the riverine barrier, the gradient, and the basal trichotomy hypotheses. I used phylogenetic and population genetics methods to reconstruct the […]
Rufous-tailed Xenops (Xenops milleri) Science Article 1 abstract This paper provides information on the behavior, distribution, and taxonomy of 36 species of rainforest and marsh birds found in the tropical lowlands of southeastern Peru. Most species discussed are little-known forest residents, but some are widespread and common in other regions, occurring in Peru only as […]
