Summary

I determined the amount of time Greater White-fronted Geese (Anser albifrons frontalis) allocated to various activities from September to May, 1980-1982 at their primary wintering areas in the Pacific Flyway of North America. The length of time spent on roosts during the day was positively correlated to day length. Geese at roost sites spent the majority of their time sleeping (24-46%), alert (17-40%), walking or swimming (6-24%), and in comfort behaviors (3-25%). The amount of time geese fed each day varied little from early autumn to late spring (4.5-4.9 hr), except during mid-winter when minimum temperatures were below freezing (3.9 hr), and immediately before migration in spring (6.3 hr). The proportion of time devoted to feeding [...]
