Did you know that hummingbird is the smallest bird in the world. There are more than 300 varieties of them, and the smallest hummingbird is called "hummingbird-bee", this bird is only 7 centimeters long and weighs 2 grams; the largest representative of the hummingbird is called the "gigantic hummingbird", its length is 21 centimeters and weighs about 20 grams.
Researchers of nature also awarded other representatives of this family with very beautiful names: "hummingbird", "snow-capped hummingbird", "hummingbird", "emerald neck", "fire topaz", "flying amethyst".
At first glance, these birds are very delicate and fragile, nevertheless they are the most hardy in the entire animal world. Hummingbirds are found in a wide variety of climates: Arizona, the coast of Nova Scotia, Argentina, even Alaska. Fun fact: hummingbirds
live only in the New World.
The average length of a hummingbird is 5, 7 centimeters, and most of the body is occupied by the tail and beak. Weighs
hummingbird approximately 1.5 grams. The length of the largest member of this family is 20 centimeters. Live
hummingbird about 9 years old.
The hummingbird has an incredibly developed heart, its volume is three times the size of the stomach and takes up half of an already tiny body. This is due to the fact that these birds lead a very mobile lifestyle, and also have a very fast metabolism. Note also that hummingbirds have several times more red blood cells than other representatives of birds.
The hummingbird's heart beats at an incredibly high rate, 500 beats per minute (and it can
rest, and in some species it can reach 1000), and during the life of this crumbs, the heart contracts 4.5 billion times, which is almost twice as many beats as the human heart beats in 70 years.
Tiny hummingbirds consume 100 times more food per unit of weight than elephants. The metabolic rate of these birds is so high that even a six to eight hour interval between meals would threaten them with death from exhaustion, but this does not happen: the hummingbird's body seems to freeze at night - their temperature drops from the usual forty-forty-five degrees to ambient temperature, metabolism slows down 10-15 times. And in the morning the hummingbirds "come to life" again and begin tirelessly to get food.
Hummingbirds fly at a speed of 80 kilometers per hour, while they make 810 flaps of their wings.
in one second. The wings move so fast that they are almost invisible. They hover motionlessly over the flower only due to the incredible speed of their wings.
With the help of a camera that can record brief moments, an interesting moment was captured when the hummingbird entered its peak. As a result, stunning data were obtained: the bird's speed is 400 of its bodies per second. If we compare the speed and body length of a hummingbird, it turns out that their ratio is much higher than that of a fighter with the afterburner turned on and a space shuttle when passing through the earth's atmosphere. At the moment of exiting the peak, the hummingbird shows such instant braking, which is beyond the control of other living organisms that conquer the air.
These little birds never mate. Family responsibilities fall entirely on
The "shoulders" of the female. She builds the nest herself and further brings up the chicks. The female hummingbird usually lays two eggs and very rarely one.
The only time a hummingbird was found on the territory of the Russian Federation. Buffy hummingbird
discovered in 1976 on Ratmanov Island (Bering Strait).
