Abstract:

In 1979 and 1980 we surveyed nesting passerine bird densities within the Bureau of Land Management's (BLM) Snake River Birds of Prey Study Area in southwestern Idaho. The BLM wished to estimate bird densities so that they could evaluate the importance of individual vegetation types to the production and maintenance of bird populations. We derived bird densities using line transect survey techniques. Line transect sampling uses statistically sound procedures and unlike the numerous ad hoc survey techniques in the ornithological literature, allows estimation of sampling variance. Without some measure of variance it is impossible to judge the precision of the density estimates and compare densities between times and areas.
