Summary
Description
This paper summarizes the results of the third of a fiveyear study on the breeding biology and habitat requirements of geese nesting at Kokechik Bay, Alaska. Data were collected from May 1st to July 7th, 1984. The primary objectives of this field season were to: observe the behavior of emperor geese and cackling Canada geese in spring; continue the study of the comparative nesting ecology of geese, with emphasis on how the choice of habitat varies between species and among successful and unsuccessful nesting pairs; continue the study of clutch size in emperor geese emphasizing the occurrence of intraspecific nest parasitism and factors influencing its occurrence; and the incubation behavior of geese and the ecological significance of that behavior.
