Survey designs and statistical methods for the estimation of avian population trends

On 12-13 April 1988 a workshop on the analysis of avian population trends was held at the Patuxent Wildlife Research Center in Laurel, Maryland. The workshop was cosponsored by the Branch of Migratory Bird Research of the Patuxent Wildlife Research Center and the Office of Migratory Bird Management. During this workshop, we hoped to bring together some of the biologists and statisticians that coordinate and analyze data from major bird surveys to discuss recent advances in analytical methods of estimating population trends, one to discuss analytical methods, and one to consider population trends of a selected species: scissor-tailed flycatchers(Tyrannus forficatus), for which a data set from the North American Breeding Bird Survey had been distributed to participants before the meeting.
