What is a double -screw cormorant?

Double -screw cormorant (FALACROCORAX auritus) is a slender black and white bird that can be found in both fresh and salty water. These habitats range from the North American coastal waters to the Lake inland and the Greeks of Central America. Bahamas and Mexico are also home to this kind of Cormorant. During the winter months, these cormorars migrate to warmer temperatures and often see them to fly together in a V-shaped formation. Young cormorars with double screwing have white feather breasts that disappear when the bird matures. The orange yellow housing on the neck and two feathered combs on the head distinguish this cormorant from other cormorant species. These feathered combs, which can be either black or white, are present when the cormorant matures and is ready for breeding.

Adult men and women look similarly as well as a thin account with a hook down to the tip. Are also almost completeThey black with a curved neck and a long tail. This long tail acts as a rudder when the cormorant with a double scratching floats and immerses underwater. Webbed Feet on the cormorant quickly drives water.

This cormorant only swims with his head above the water and can dive into 25 feet (762 cm) in search of prey. This bird lacks oil glands that would normally cause its feathers. Because its feathers absorb water rather than repel it, the cormorant is more capable of diving to greater depth in the search for food. As soon as the bird leaves the water, it must stand upright and spread the wings to allow them to dry.

The diet with a double screw consists mainly of fish either of fresh water or salt water. They also feed on shrimp, small amphibians and invertebes. When feeding large fish, the cormorant emerges with the fish in the beak and place it so that the fish can be all over the association.

The period of reproduction for cormorant with a double screw is from mid -April to mid -June. The man and female breeding of the couple are gathered with sticks and twigs to build a nest high on a tree or on a cliff. Cormorars living in coastal waters can use seaweed to build their nests.

Female cormorank usually puts three to four blue chalk eggs that will be incubated in a nest for about a month. Once the eggs hatch, the chickens and the female cormorant will take care of the chickens. The chickens should be ready to leave the nest in 35 to 40 days. Cormorars with double screwing are very versatile and have been able to adapt and survive in various stations.
