Suddenly a light of jade flashed, the wings flapped gently and disappeared in the air, an illusion appeared quickly to make it impossible to determine whether it was a bird or an insect. Fortunately, that moment came up again, this time in a better perspective and it could be confirmed that it was exactly a bird - Hummingbird , an intermediate " product " of the process. evolution between insects and birds.

People found this hummingbird in the Americas. According to biologists, hummingbirds have many different varieties and change colors according to geographical regions to adapt to the environment and climate conditions there. Of the 330 species, only 16 have been identified as originating from northern Mexico, the rest cannot be verified because they are known as migratory birds. Their journey may reach 2,500 miles (more than 40,000km): from Alaska to the country of Argentina, from the Arizona desert to the coast of Nova Scotia, from the lowlands in the forests of the Brazilian territory to the Andes .

They live wherever they can be. According to scientists, hummingbirds normally raised in cages can live for 17 years. This is amazing compared to a simple organ structure in a small body with an average weight of only 5-6 grams. The heart is tiny but averages 500 beats per minute (while parked). It is estimated that within 17 years the heart beats about 4.5 billion times - almost twice as much as the total beat of a 70-year-old person.

The birds are so flexible when they live, but when they die, their hollow bones are quickly decomposed and never fossilized. That is why no fossil specimens of this bird have been found, although they have been around for a long time.
