Canada goose
The Canada goose, known scientifically as Branta canadensis, is a large bird commonly found in North America and parts of Europe. Recognizable by its gray-brown plumage, black neck, and distinctive white cheek patch, this bird measures between 30 and 43 inches in length. Canada geese are known for their impressive migratory capabilities, flying in V-formations at speeds up to 62 miles per hour and covering distances of 1,500 miles in a single day. These herbivorous birds primarily feed on land, consuming berries, leaves, and crops such as oats and corn, and can spend up to 12 hours a day foraging.
Socially, Canada geese are often seen in large flocks, which are structured into family groups. They are known for their strong pair bonds, mating for life and often returning to the same nesting sites each year. Breeding typically occurs in spring near water bodies, with females laying up to 10 eggs in a nest made from grass and twigs. After hatching, goslings are precocial and can swim almost immediately. The male plays a significant role in protecting and nurturing the young until they are capable of flying at around six to seven weeks old. This species exhibits fascinating behaviors and social structures that contribute to its well-known presence in various habitats.

Canada goose
A flock of loudly honking Canada geese flying overhead in a V-formation is common in North America. Some species of these large birds migrate great distances each year, reaching speeds of up to 62 miles (100 kilometers) per hour and traveling up to 1,500 miles (2,400 kilometers) in a single day.

The gray-brown plumage of the Canada goose is a well-known sight on the waterways and in the fields of North America and parts of Europe. Its chest and underside are white, while its long neck and small head are black. From one ear to the other, running underneath the chin is a broad, white band. A Canada goose may measure between 30 and 43 1/3 inches (76 and 110 centimeters), depending on the species. The smallest species, like the crackling goose, weighs around 4 1/2 pounds (2 kilograms) while the giant Canada goose may weigh nearly 14 1/2 pounds (6 1/2 kilograms). On average, Canada geese weigh 6 1/2 to 24 pounds (3 to 11 kilograms). The powerful wings that carry the migrating goose across its range may reach 6 1/2 feet (2 meters) from tip to tip.
Canada geese feed for up to 12 hours each day, eating most of their food on land contrary to other species in the Anseriformes order. The herbivore eats berries, leaves, stems, roots, flowers, and seeds. In the winter when there is less food available, they eat crops like oats, soybeans, and corn. They also eat aquatic vegetation by tipping their tails up in the air and their head down beneath the water.
Flocks may have as many as several hundred geese and are divided into strong family groups. The members of a flock feed, roost, and migrate together for most of the year. The geese become more aggressive and territorial shortly before and during breeding season. Geese form pairs and mate for the first time when they are two to four years old. The male and female mate for life and remain together year-round. Some of these pairings may last 24 years, the maximum life span for Canada geese. One pair reportedly stayed together for 42 years.
Breeding most often takes place near the water in the spring. A low pile of grass, leaves, and twigs forms the nest, which the female usually builds near water. The pair may reuse the same nest each year. The female incubates the eggs for one month and hatches up to 10 chicks, called goslings. The male helps care for and protect the goslings after they hatch. Goslings can swim immediately. Six to seven weeks after hatching, the goslings fledge, or can fly, because all their flight feathers have developed.
