Geese names
Branta canadensis
EOL Text
A chemical called methiocarb is being used on grass to prevent geese from grazing on it in some areas. Methiocarb makes the geese feel sick, but thus far has not resulted in any deaths. The toxic effects of this chemical are still being researched. Over 200 geese have been killed by the chemical parathion in Texas. Golden eagles and bald eagles have been seen eating the bodies of geese that have been killed by parathion which means it could potentially be very dangerous for them as well.

Global Range: (>2,500,000 square km (greater than 1,000,000 square miles)) Breeds from central and southeastern Alaska east across northern Canada and southern Victoria Island to western Melville Peninsula, northeastern Manitoba, northern Ontario, northern Quebec, and southern Baffin Island (recently naturally established in western Greenland) south to southwestern British Columbia, northeastern California, northern Utah, south-central Wyoming, South Dakota, Kansas, northern Arkansas, western Kentucky, southern Ohio, Pennsylvania, northern Virginia, and Maryland. Breeding populations in the southern prairie states were extirpated, but many have become reestablished. Birds in eastern states south of Great Lakes and Massachusetts result from relatively recent natural southward extension of breeding range and to great extent from introductions. Feral populations resulting from introductions may occur almost anywhere in the United States (AOU 2004).
Winters from the southern part of the breeding range through most of the United States and into northern Mexico. Introduced and established in Great Britain, Iceland, southern Scandinavia, and New Zealand. Accidental in Hawaii, Greater Antilles, and the Bahamas.
This goose feeds on aquatic vegetation and grasses. It has become an agricultural pest in some areas where it moves from water bodies to fields in order to feed (3). Although often aggressive, this goose is gregarious, occurring in flocks during winter and breeding colonially on larger water bodies (5). The nest, a down-lined scrape, is typically situated among vegetation (5). During early April between 5 and 6 (up to 11) white eggs are laid. The female incubates the eggs for 28-30 days, while the male guards the nest close-by (5). Both sexes care for the young, which fledge after around 9 weeks, and stay with the parents throughout the winter (5).

The Canada goose was introduced to England around 300 years ago. It is now the most familiar goose in Britain (3). This large goose has a long black neck, and a black head with a prominent white patch, which forms a strap around the throat that extends onto the face (2). The body is brown, with paler underparts. The sexes are similar in appearance; juveniles can be identified as the throat-strap is brownish, and the head and neck are duller (2). This vocal goose produces a range of deep honking calls (2), a loud 'aa-honk' in flight and hissing sounds when threatened (5).

Canada Geese are found throughout North America. There are four subspecies (or populations); each is found in a different area of North America. These subspecies are the southern, northern, western and Aleutian-Canadian populations. The southern population ranges from 60 degrees north latitude to the Rockies and Atlantic Ocean. The northern population ranges north of 60 degrees north latitude in the Arctic and Subarctic. Canada geese travel to the southern parts of the United States during the winter. The western population is found along the coasts of Alaska and British Columbia. The Aleutian-Canadian population is rarely found. A general trend in all subspecies is that they they spend summers in the northern parts of North America, especially Canada, and migrate south to areas of the United States in the winter months.

After its introduction as an ornamental species, the Canada goose did not spread away from parks and stately homes until after the Second World War (3). It has since increased greatly in numbers, and its range has expanded throughout Britain (3), although it is not as common in Scotland and Wales (5). Its natural range occurs throughout Canada and northern USA. It has also been introduced to Ireland, Sweden, Finland and Norway (5).

Comments: Various habitats near water, from temperate regions to tundra. In migration and winter, coastal and freshwater marshes, lakes, rivers, fields, etc. On Admiralty Island, Alaska, commonly perches in trees. In the eastern U.S., common on lawns adjacent to water in urban-suburban areas.
Breeds in open or forested areas near lakes, ponds, large streams, inland and coastal marshes. The nest is built on the ground or on an elevated place (muskrat house, abandoned heron's nest, rocky cliffs, etc.) (Terres 1980). Usually returns to nesting territory used in previous year.
Canada geese have good eyesight, which is necessary for flight. They must move their heads in order to see all the way around themselves. However, their eyes are close to their crowns on the side of their heads, enabling them to see more than 180 degrees (closer to 270 degrees) horizontally and vertically. They have mostly monocular vision. Canada geese have excellent hearing and the ears are located on the side of its head. Canada geese often use body movements to communicate with each other. These geese also have the ability to make at least 10 different calls
Communication Channels: visual ; tactile ; acoustic

Canada geese have black necks, bills, and heads with a white strap under their chins and occasional white patches on other parts of their body. The body of Canada geese is usually brownish-gray although subspecies have slightly different colors. In some of the smaller subspecies the body is dark brown in color whereas, in some of the larger subspecies, the body is a light gray. The subspecies also differ in their average weights. Underneath, the colors are much lighter and almost white on the tail. During flight the tail shows a white semi-circle just above the black tail. Females look similar to males, but may be slightly smaller.
Canada geese have strong, tapered bills that are bordered with lamellae. Lamellae are teeth-like projections of the bill that are used to cut vegetation. Their feet are black. These geese have large wings that can be used as weapons by thrashing them at intruders. The wingspan of Canada geese ranges from 127 to 173 cm.
Goslings, or young Canada geese, are yellow with some greenish-gray coloring on top of their heads and backs. Goslings in different subspecies are slightly differently colored. Goslings of the darker subspecies have a brownish olive or blunt yellow coloring while those of the lighter subspecies are lighter and brighter in color. These colors fade as the gosling grows into the adult color pattern. All goslings have black or blue-gray bills and legs that become darker as they age.
Range mass: 1100 to 8000 g.
Range length: 90 to 200 cm.
Range wingspan: 127 to 173 cm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: male larger
