Ducks can live between 2 and 12 years, depending on the species. They are found on every continent except Antarctica. Ducks have no nerves or blood vessels in their feet so they cannot feel hot or cold, and they have three eyelids. A male duck is called a drake, female ducks are called hens and baby ducks are ducklings.
Historically, these birds have been known as “giant” Canada geese and are the largest geese in the world. Most adults weigh between 5 and 14 pounds, with some weighing up to 20 pounds. Females weigh slightly less than males. In the early 1900s, giant Canada geese nearly became extinct. Geese mate for life, which can be anywhere from 10 to 25 years. Baby geese, called goslings, have been known to follow just about anything that moves, from dogs to humans, mistaking the creatures for their mother.
Magpies can reach 16 to 18 inches in length and 7 to 9 ounces in weight. They are easily recognized, black-and-white-colored birds. Upper parts of the body and wings are black with iridescent green, purple and blue sheen. The belly, parts of the wings, flanks and rump are covered with white plumage. Magpies recognize themselves in mirrors and will eat just about anything, including bird eggs and chicks. A group of magpies is called a parliament.
Trumpeter swans nearly became extinct in the late 1800s because people hunted the birds for their skins and quills. In 1933, only 77 trumpeter swans were breeding in Canada and only 50 in the United States. There are now approximately 20,000 trumpeter swans in the world. Swans live for approximately 20 to 30 years. Baby swans are called cygnets. Swans usually mate for life, though “divorce” does sometimes occur, particularly following nesting failure, and if a mate dies, the remaining swan will take up with another.
