The patient predator : foraging and population ecology of the Great Blue Heron Ardea herodias in British Columbia / by Robert W. Butler.: CW69-1/86E

This report presents the results of a six-year study (1986-91, including five breeding seasons and four winters) of the diet, food availability, foraging behaviour, use of habitats by age-classes and sex-classes, spacing of breeding colonies, and survival of the Great Blue Heron Ardea herodias on the Pacific coast of British Columbia. The general thesis of this study is that the availability of food energy largely dictates when herons use foraging habitats, the time of year that they breed, and which individuals survive.--Abstract
