Habitat Specialization by Birds in Western Amazonian White-sand Forests

In the Peruvian Amazon, white-sand forests are patchily distributed and restricted to a few localities in the North. Although recent studies have documented patterns of habitat specialization by plants in these unique forests, very few studies of the fauna of these habitats have been conducted. The species composition of the avifauna of the white-sand forests at six localities in the region was...

The mystery of nocturnal birds in tropical secondary forests

Spatial relationship of resident and migratory birds and canopy openings in diseased ponderosa pine forests

A method is described for predicting the spatial distribution of individual birds using presence data. The approach is demonstrated using a statistical habitat association model developed for resident and migratory birds on a 12 ha plot of ponderosa pine (Pinus ponderosa) heavily infested with southwestern ponderosa pine dwarf mistletoe (Arceuthobium vasinatum subsp. Cryptopodum (Englemann) Haw...

Density and community structure of breeding birds in Macedonian pine Pinus peuce forests in Bulgaria

Breeding bird density and community structure in Macedonian pine forests were studied during 3 successive years (2004-2006) in the Pirin national park, Bulgaria. Bird sampling, using point counts, recorded 2583 birds belonging to 31 species. The relative density was computed for the most abundant 20 species by the DISTANCE software. The results show that Macedonian pine forests hold significant...
