Abstract:

The U.S. Fish and Wildlife Service regularly conducts marine bird survey efforts along the Atlantic coast of the U.S. The Atlantic Marine Assessment Program for Protected Species maintains the resulting data and other historical survey data. The nature and structure of this data and the survey designs are unique while still lending themselves to a variety of geospatial analysis techniques. Bird diversity along the Atlantic Coast and various other community analyses are examined. Possible models from all available surveys are presented and evaluated for their predictive and explanatory value. Additional covariates are considered to determine if they add precision to the detection rate and abundance estimations. While accounting for natural imperfection in detection, necessary survey modifications and ongoing design changes, methods for reducing the bias in current and future seabird survey estimates are discussed.
