Also called the wood ibis, the wood stork is one of the largest wading birds found in North America, and it is the only stork
found in the United States. An adult stands about 3.3 feet tall, and its wingspan can reach over five feet.
Its plumage is white, the head is bald and grayish, and its tail, legs and flight feathers
are black. The bill is large, down-curved and pale yellow and can reach up to 9 inches long. On average, wood storks weigh about 7 lb, and though their heavy weight limits their flight distances, they are known to be great acrobats when descending, performing marvelous turns, dives, and roles.
Wood storks prefer to dwell in wetlands, and they can feed and nest in fresh, brackish, or salt water. They prefer to hunt in shallow water or muddy-bottom banks. Diet consists of fish, crayfish, amphibians, and even young alligators and snakes. Prey is caught by submerging its beak about two to three inches in the water and feeling for fish passing by. They are able to startle their prey out of their hiding places by stirring the water with their feet. Wood storks prefer to come together in colonies
during nesting season. The nests are built near the top of trees or shrubs, sometimes as high as 100 feet. Females lay up to five eggs,
and both parents help to incubate the eggs. The eggs hatch after 30 days and
both parents feed and care for the young.
This species is mainly threatened by loss of habitat and change in land use and water levels, especially in Florida's wetlands. The birds depend on these wetlands for nesting and feeding, and they are also subject to predation by other creatures such as raccoons. In the 1930s populations were about 20,000, but
today only about 5500 nesting pairs remain. Wood storks are listed on the Federal List of endangered species and they are also protected under the US Migratory Bird Treaty Act.

Rare white giraffes sighted for the first time in Kenya
A pair of white giraffes have been discovered in Kenya recently by local residents. According to the residents, the beautiful white giraffes were very close to them, extremely calm, and did not seem disturbed by their presence. The residents immediately tipped off conservationists who then found the giraffes in the Ishaqbini Hirola Conservancy, an already established safe space dedicated to the preservation of antelopes in the area.
