Egg measurements for three endangered species

January 1, 1972

From 1967 through 1969, external dimensions of the eggs of three endangered species of birds were measured. Included were 33 eggs of the Whooping Crane (Grus americana), 158 eggs of the Aleutian Canada Goose (Branta canadensis leucopareia), and 809 eggs of the Masked Bobwhite Quail (Colinus virginiana ridgwayi). In the literature, there are only scattered reports of small samples of Masked Bobwhite Quail and Whooping Crane eggs and, to the best of our knowledge, no measurements of Aleutian Canada Goose eggs have been reported. The information presented herein is intended to augment knowledge of these three threatened forms of North American wildlife. We wish to thank members of the staff of the Endangered Wildlife Re- search Program for assistance in gathering the data.
