Abstract
We carried out a study in a dry or semideciduous Chiquitano forest in the Lomerío region, one year after it had been selectively logged. We assessed species richness, diversity, relative abundance, and guilds of birds (126 individuals, 32 species) captured with mistnets in logging gaps and in adjacent undisturbed areas. Species richness, diversity, and abundance diminished consistently from large to small gaps and to unlogged sites, although differ-ences between treatments not always were statistically significant. The insectivores Thamnophilus sticturus, Cnemotriccus fuscatus and Thryothorus guarayanus were the most frequent birds in thelarge gaps, whereas Thamnophilus sticturus, Sittasomus griseicapillus, Thryothorus guarayanus y Basileuterus culicivorus were the most frequent birds in small gaps and unlogged sites. Fromeight examined guilds, only the abundance of sallying species showed a significantly higher abundance in gaps, while the remaining guilds did not show preferences for any of the treatments. Logging activities after one year apparently did not have a strong impact on the birdcommunities of this study area. However, qualitative changes in the bird community could be sosubtle as to be noticed only after many years.
