Bursal depths of lesser snow and small Canada geese

January 1, 1969

Bursa of Fabricius depths of 88 lesser snow geese (Anser c. caerulescens) and 69 small Canada geese (Branta canadensis hutchinsii/parvipes complex) were measured. Bursal depths were unreliable indicators of age-classes of lesser snow geese and small Canada geese; previously, the same had been found to be true for large Canada geese (B. c. interior). Regression in size or closure of the bursa first occurred at 17-20 months of age (yearlings) in lesser snow geese and small Canada geese, but at 29-32 months of age (2-year-olds) in large Canada geese.
