A COMPARISON OF POINT COUNTS AND SOUND RECORDING AS BIRD SURVEY METHODS IN AMAZONIAN SOUTHEAST PERU

We tested the ability of sound recordings relative to that of point counts to estimate species richness in the Tambopata Reserve in southeast Peru. We tested the effect of two environmental factors (estimated richness and presence of noisy species) and two attributes of species (abundance and foraging height) on estimates of species richness made by point counts and sound recordings. Sound recordings are preferred to point counts when richness …
