What is Barrow's Goldenney?
Barrow's Goldenney is a type of duck common to Canada, Greenland, Iceland and the North United States. This duck usually winter in mountain areas and spends their reproduction period around the lakes, where the fish -eating populations are small or non -existent. The scientific name for Barrow's Goldenneye is Bucephala Islandica .
Medium duck, Barrow's Goldenney diameters between 17 and 19 inches (43-48 cm) in length. Both unresolved man and female look very similar, with dark brown heads, gray backs and wings, white chest and abdomen and small triangular accounts. Breeding males, however, have a dark purple, almost black, head with a white crescent near their accounts. Their back and wings are black, with square white marks on each side and white secondary feathers on the wings. For this reason, they tend to avoid water bodies with many insect fish, so they do not have a high competition for a selected food source. To capture his prey, Barrow'sGoldenneye is immersed under water from the surface position. Sometimes the whole flock is immersed by Unison.
Long life, the maximum age that has ever been a record for Barrow's Goldenney, was 18 years old. Females mature later than many other ducks - usually do not start to behave until they reach three years. The couple are formed after the courtship process and are dissolved after the woman puts eggs. However, Bondy is usually re -occupied in the next reproduction period.
nests are usually built in tree cavities and are lined with feathers. Females usually return to their homes to behave, and once a suitable nesting point is found, they often use the same caits year after year. Normally the woman puts six to 12 eggs and incubates them alone. From time to time, the female will lay eggs in another nest and the egg owner will take care of the eggs. Once the eggs hatch, the ducklings are mobile after two days. Young fledge in eight or nine weeks.
Although the mother takes care of her ducklings until they enjoy, the young need little care. The ducklings are very independent, able to find food on their own. However, all ducks are provided with some parental care and women will take care of more than one young when young found themselves without a mother.
