Olor columbianus (Ord). Whistling Swan. Transient and winter resident, formerly common, now rare. Many specimens are on record; at least four were taken in winter.
No subspecies recognized.
Olor buccinator (Richardson). Trumpeter Swan. Formerly occasional migrant, no longer occurs in Kansas. All specimens from Kansas alleged to be of this species are actually Whistling Swans. The early sight records seem valid, however, and the species should remain on the state list.
No subspecies recognized.
* Branta canadensis. Canada Goose. Common transient; some winter in suitable places. This species was found nesting along the Missouri River near Atchison by early explorers. Modern breeding records probably pertain to captives or their descendants.
Subspecies in Kansas: B. c. moffitti Aldrich, B. c. leucopareia (Brandt), B. c. minima Ridgway, and B. c. hutchinsi (Richardson) have been collected in Kansas. Additionally, subspecies interior Todd and parvipes (Cassin) probably pass through the state but no specimens have been saved. Canada Geese of widely varying size are regularly seen in migration.
Branta bernicla. Brant. Accidental. Several sight records and one specimen: unsexed bird (KU 7490), Leavenworth County, November 15, 1879, A. Lange. Some hunters refer to immature Blue Geese as "brant." Orville O. Rice saw 4 brant 2 miles north of Burlington, near the Neosho River, Coffey County, March 24, 1955, that appeared to be Black Brant, Branta nigricans (Lawrence).
Subspecies in Kansas: B. b. hrota (Müller).
Anser albifrons. White-fronted Goose. Regular transient throughout state, more common in central and western parts.
Subspecies in Kansas: A. a. frontalis Baird.
