Reliability of the Breeding Bird Survey: Effects of restricting surveys to roads Reliability of the Breeding Bird Survey: Effects of restricting surveys to roads

Breeding Bird Surveys (BBS), which are widely used to monitor trends in avian populations (e.g. Robbins et al. 1989, Sauer and Droege 1993), are conducted along roads but are used to infer changes in regionwide populations. Such inferences may be inaccurate if trends in habitat along roads differ from regionwide trends. For example, if forest cover regionwide remained constant but forest...

Point count length and detection of forest neotropical migrant birds Point count length and detection of forest neotropical migrant birds

Comparisons of bird abundances among years or among habitats assume that the rates at which birds are detected and counted are constant within species. We use point count data collected in forests of the Mid-Atlantic states to estimate detection probabilities for Neotropical migrant bird species as a function of count length. For some species, significant differences existed among years...

Sample size and allocation of effort in point count sampling of birds in bottomland hardwood forests Sample size and allocation of effort in point count sampling of birds in bottomland hardwood forests

To examine sample size requirements and optimum allocation of effort in point count sampling of bottomland hardwood forests, we computed minimum sample sizes from variation recorded during 82 point counts (May 7-May 16, 1992) from three localities containing three habitat types across three regions of the Mississippi Alluvial Valley (MAV). Also, we estimated the effect of increasing the...
