Howell, T.R. 1946 Branta canadensis Dec. 14. Sacramento National Wildlife Refuge, Glenn Co., Calif. — There were at least two races of this species observed here — leucopareia and minima. The former is about the size of a white-front, and is somewhat pale on the breast; the latter is only a little larger than a mallard, brownish (and hence darker) on the breast, quite short-billed, and with a high-pitched note. The races seemed to mix with one another indiscriminately, and occasionally with flocks of snows and white-fronts. They preferred the drier stubble fields, and were observed picking gravel out of the road.
