Evaluations of Techniques for Estimating Fall Age Ratios of Canada and Snow Geese

Higgins, Kenneth Frederick

… checks for estimating productivity of lesser snow geese (Anser caerulescens caerulescens) and small Canada geese (Branta cnadensis hutchinsii-parvipes complex) was studied at Sand Lake and Tewaukon National Wildlife Refuges during fall, 1965 and 1966. Age-ratios obtained from flock counts …

Effects of body size on goose behavior: lesser snow goose and Ross's goose

Jonsson, Jon EinarRenewable Natural Resources2022

Body size is highly variable among geese, both at intra- and interspecific levels. Interspecific variation in several behaviors has been attributed to differences in body size in geese: incubation constancy, tendency to maintain family units, and time spent foraging. Body size has important …
