⢠Duskys are most commonly mistaken for Tavernerâs and cacklers due to similarities in size and body shape and coloration. It breeds farther northward and westward than does the Canada Goose. Boston. maxima) has been recorded in Washington as a rare winter visitor. In contrast, the Dusky Canada goose population remains at relatively low numbers, with 2007 breeding population ⦠On the east coast, the most common subspecies would be hutchsinii (Richardson's). [83], In 2000, the North American population for the geese was estimated to be between 4 million and 5 million birds. and Wildlife. However, most subspecies of the cackling goose (exclusive of Richardson's cackling goose, B. h. hutchinsii) are considerably smaller. Salinity plays a role in the growth and development of goslings. [27], Canada geese were introduced as a game bird into New Zealand in 1905. Alfred A. Knopf, New

The distinctive and well-known Canada goose is a North American native that has been extensively introduced to UK, Scandinavia, and North Sea nations from Denmark to France, Russia and Ukraine, as well as New Zealand. Its first director, Harvey K. Nelson, talked Forrest Lee into leaving Minnesota to head the center's Canada goose production and restoration program. If one dies, the other may find a new mate. [40][41], Known predators of eggs and goslings include coyotes,[42] Arctic foxes (Vulpes lagopus), northern raccoons (Procyon lotor), red foxes (Vulpes vulpes), large gulls (Larus species), common ravens (Corvus corax), American crows (Corvus brachyrhynchos), carrion crows (in Europe, Corvus corone) and both brown (Ursus arctos) and American black bears (Ursus americanus).[18][43][44][45][46]. As soon as the goslings hatch, they are immediately capable of walking, swimming, and finding their own food (a diet similar to the adult geese). In the past, the Cackling Goose was considered to be either the same species (conspecific) or a subspecies of the Canada Goose.In July 2004, the American Ornithologists' Union's Committee split them up into two separate species based on genetic studies and differences in size, voice and breeding habitat: the larger bodied Canada Goose ⦠The Canada Goose is a highly variable species which has long caused headaches for taxonomists. A small, short-necked, stubby-billed goose. [citation needed][36] The early migrants have a tendency to spend less time at rest stops and go through the migration much faster. Likely to fly low and can decoy small flocks. Canada geese belong to subfamily Anserinae. The Canada goose also eats beans and grains such as wheat, rice, and corn when they are available. Canada Geese can respond to external climatic factors by adjusting their laying date to spring maximum temperatures, which may benefit their nesting success. Canada Goose Complex. Cackling Goose (Branta hutchinsii minima) photos by Larry Jordan. The various subspecies of Canada goose range in size from 2 kg (4.4 pounds) in the cackling goose (B. canadensis minima) to about 6.5 kg (14.3 pounds) in mature males of the giant Canada goose (B. canadensis maxima). [55] Canada geese are quite wary of humans where they are regularly hunted and killed, but can otherwise become habituated to fearlessness towards humans, especially where they are fed by them. In the United States, the Canada goose is the second-most damaging bird strike to airplanes, with the most damaging being turkey vultures. [37], Flying in the V formation has been the subject of study by researchers. Due in part to the interbreeding of various migratory subspecies with the introduced nonmigratory giant subspecies, Canada geese are frequently a year-around feature of such urban environments. There are also resident Atlantic coast populations, such as on Chesapeake Bay, in Virginia's James River regions, and in the Triangle area of North Carolina (Raleigh, Durham, Chapel Hill), and nearby Hillsborough. The following guide to Canada Goose sub-species is copied nearly word
[29], Like most geese, the Canada goose is naturally migratory with the wintering range being most of the United States. Branta was a Latinised form of Old Norse Brandgás, "burnt (black) goose" and the specific epithet canadensis is a New Latin word meaning "from Canada". They are all distinguished by a black head and neck with white cheeks and chin strap. should be directed to either the Oregon or Washington Department of Fish
[61] Addling goose eggs and destroying nests are promoted as humane population control methods. As you can likely tell, the cackling goose looks remarkably similar to the Canada goose. Their large size and tendency to fly in flocks may exacerbate their impact. The seven subspecies of this bird vary widely in size and plumage details, but all are recognizable as Canada geese. The smallest cackling goose, B. h. minima, is scarcely larger than a mallard. In general, the subspecies nesting farther north are smaller in size and darker in color to the west. Figure 1. Discover high quality jackets, parkas and accessories designed for women, men and kids. Size and shape are best identification clues; note more rounded head, shorter neck, and smaller bill on Cackling. [65] In both countries, commercial transactions such as buying or trading are mostly prohibited and the possession, hunting, and interfering with the activity of the animals are subject to restrictions. If I assume that the Canada Goose is of the western moffitti subspecies that is common in the west then, from Figure 2 in the Sibley Guide the expected ratio would be about 1.66. Canada geese live on farm ponds, lakes, and marshes. However, seven subspecies of greater Canada geese exist in North America ranging in weight from approximately 3 to 24 pounds. Houghton
[33], During the second year of their lives, Canada geese find a mate. The geese were first introduced in Britain in the late 17th century as an addition to King James II's waterfowl collection in St. James's Park. This is recorded from the many tagged geese which frequent the East Coast. They may then bite or attack with their wings. North America : widespread; Subspecies. Ducks, Geese and Swans of North America. Madge, S and H. Burn. They were introduced in Germany and Scandinavia during the 20th century, starting in Sweden in 1929. Owing to its adaptability to human-altered areas, it has become one of the most common waterfowl species in North America. Yet their successful recovery has led to a backlash against them in many areas. The British Ornithologists' Union followed suit in June 2005.[9]. The white-cheeked geese of North America were long considered to make up just one highly variable species, Canada Goose. It is believed that the body sends out more T4 to help the goose's body with this long task by speeding up the metabolism and lowering the temperature at which the muscles work. [14] The British longevity record is held by a specimen tagged as a nestling, which was observed alive at the University of York at the age of 31. In contrast, the Dusky Canada goose population remains at relatively low numbers, with 2007 breeding population counts estimated at 10,000 birds. They are all distinguished by a black head and neck with white cheeks and ⦠Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. Wing appearance narrow and long in relation to body.

There is a small backward projecting hook on ⦠Raftovich, R.V., Chandler, S. C. and Wilkins, K.A. Their taxonomy has been confused by the introduction of mixed subspecies, and will likely remain unclear for a long time. Most of the species that prey on eggs also take a gosling. The success of this common park species has led to its often being considered a pest species because of its excrement, its depredation of crops, its noise, its aggressive territorial behavior towards both humans and other animals, and its habit of begging for food (caused by human hand feeding).
