Populations of ten Amazonian bird species were sampled on opposite banks of the Rio Teles Pires, a headwater stream of the Rio Tapajos, in the Alta Floresta region, northern Mato Grosso, Brazil. The river is 100-300 in wide in this region. We fo[...]

Aerial flycatching-the lightning-fast seizure of flying small birds in the beak of larger, not normally predatory birds, only a few cases of which are treated in the literature-is here described and discussed for white storks (Ciconia ciconia) a[...]

Birds have brains that are comparable in size to those of mammals. However, variation in relative avian brain size is greater in birds. Thus, birds are ideal subjects for comparative studies on the ecological and behavioral influences on the evo[...]

We tested for morphological convergence in conifer specialists among 88 passerines belonging to seven different phylogenetic lineages by discriminant factor analysis. We found a parallel trend among the seven lineages in body mass and digital pa[...]

The Passeridae are characterized by possessing a neomorphic preglossale bone in the tongue and a uniquely enlarged M. hypoglossus anterior forming part of the "seed-cup" used to orient and hold seeds in position when they are being husked. The p[...]
