Birds treat vertebrate warm-blooded animals, their distinctive feature is presence of plumage and wings. The most part of birds practically carries out all life in a condition of flight. At height they hunt, breed and even sleep. Speed of flight plays a large role for representatives of this class of animals.
The fastest bird on the planet
Two views – a falcon Sapsan and a black martin fight for the right to be called the fastest bird on the earth. However two of these representatives of the bird's world are considered as the best in two different types of speed. The falcon Sapsan gathers the largest speed in dive, and the black martin leaves no chance for a falcon in horizontal flight.
Falcon Sapsan
This is a small bird of family falcon. By the sizes she reminds a crow, only plumage at it light gray color. The beak and claws of a falcon are intended for hunting and a razdelyvaniye of meat of animals. According to measurements of biologists, this bird in the diving flight is capable to gather the speed of 322 km/h that c is equated to 90 m/. This fastest being on the planet. Such prompt speed is necessary for a falcon for hunting. Having noticed the victim, he does not pursue it, and rises over it, puts wings and dives down. At right angle to the earth the falcon stoops down on the victim and sticks into it the long claws.
The diving blow of a falcon Sapsan so strong that even at large birds at collision the head sometimes flies away.
Black martin
Though the black martin also does not gather so amazing speed as a falcon, but in horizontal flight it does not have equal. This small bird is capable to gather horizontal speed over 160 km/h. Plumage of a martin is painted in dark-brown color with slightly metal outflow. The black martin in Northern and Central Asia and also in some areas of Central Europe meets. Most often this bird can be noticed in big cities.
The black martin can be in a condition of flight up to 4 years. In air he drinks, sleeps, eats and copulates.
Fast giant or serogolovy albatross
It is necessary to mark out the real giant in the world of the flying birds – a serogolovy albatross. According to observations of scientists, this large bird is capable not only to gather flight speed in 150 km/h, but also to dive behind production into the sea on depth up to 8 meters. The albatross eats squids, fish and mollusks. Serogolovy albatrosses have one more unique property – in their stomachs fat which remains in the top compartment of digestive body is laid. With its help the bird is protected from opponents, feeds baby birds and also supports activity during distant flights.
