Snakes
Snakes are found on every continent except Antarctica and range in size from the tiny, 4-inch (10 centimeter) long thread snake to pythons and anacondas of up to 25 feet (7.6 meters) in length. In order to accommodate snakes’ narrow bodies, paired organs (such as kidneys) appear one in front of the other instead of side by side.
The alligator has been described as a ‘living fossil’ from the age of reptiles, having survived on earth for 200 million years. An average American alligator’s weight and length is 800 pounds (360 kilos) and 13 feet (4.0 meters) long, but can grow to 14.5 feet (4.4 meters) long and weigh 1,000 pounds (450 kilos).
Albinism in birds is rare, occurring to any extent in perhaps 1 in 1800 individuals, though near Prypiat, Ukraine most sparrows have slight albinism. Albino birds have white feathers in place of colored ones on some portion of its body. A bird that’s naturally white, such as a swan, goose, or egret, is not an albino, nor is a bird that has seasonally alternating white plumage.
Mockingbirds are a group of New World passerine birds from the Mimidae family, best known for the habit of some species mimicking the songs of insect and amphibian sounds as well as other bird songs, often loudly and in rapid succession.
The Snowy Egret is a small white heron, and the American counterpart to the very similar Old World Little Egret, which has established a foothold in the Bahamas. Adults are typically 24 inches (60 centimeters) long. They have a slim black bill and long black legs with yellow feet. The area of the upper bill in front of the eyes is yellow, but turns red during the breeding season when the adults also gain re-curved plumes on the back, making for a ’shaggy’ effect.
The herons are wading birds in the Ardeidae family. Some are called egrets or bitterns instead of herons. However, egrets are not a biologically distinct group from the herons, and tend to be named differently because they’re mainly white and / or have decorative plumes, and while having the same build as the larger herons, tend to be smaller. Some members of this group nest colonially in trees, others, notably the bitterns, use reedbeds.
Kookaburras, or Cookaburras, are large to very large terrestrial kingfishers native to Australia and New Guinea, with a total length of 11 to 17 inches (28 to 42 centimeters). They’re generally not closely associated with water, found in habitats ranging from humid forest to arid savanna, as well as suburban and residential areas near running water and where food can be searched for easily.
Owls are an order of birds of prey classified in the order Strigiformes, in which there are over 200 extant species, found in all regions of the Earth except Antarctica, most of Greenland, and some remote islands. Owls are mostly solitary and nocturnal, with some exceptions such as the Burrowing Owl. They typically hunt small mammals, insects, and other birds, though a few species specialize in hunting fish.
The ostrich is a large flightless bird native to Africa (and formerly the Middle East), and share the order Struthioniformes with the Emu, kiwis, and other ratites. It’s distinctive in its appearance with a long neck and legs and the ability to run at speeds of about 46 mph (74 km/h) — the top land speed of any bird. The ostrich is the largest living species of bird and lays the largest egg of any bird species.
Penguins are a group of aquatic, flightless birds living almost exclusively in the Southern Hemisphere. Highly adapted for life in the water, penguins have countershaded dark and white plumage, and their wings have become flippers. Most penguins feed on krill, fish, squid, and other forms of sealife caught while swimming underwater. They spend about half of their life on land and half in the oceans.
