Limited geographic variation in the vocalizations ofa neotropical furnariid, synallaxis albescens

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 […]

Foraging and diet composition of the black-capped foliage-gleaner (philydor atricapillus)

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 […]

MOLECULAR SYSTEMATICS, PHYLOGEOGRAPHY, AND POPULATION GENETICSOF XIPHORHYNCHUS (AVES: DENDROCOLAPTIDae) IN THE AMAZON BASIN

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 […]

OBSERVATIONS OF SOME UNUSUAL RAINFORESTAND MARSH BIRDS IN SOUTHEASTERN PERU

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 […]
