The life cycle of sparrows can be divided into stages and despite the fact that many people die in the first year of life, if they survive, they usually exceed one year of life. In general, this bird has a life expectancy of three to five years, as it spends the first year of life.
Hummingbirds are one of the smallest bird species in the world. It is native to America and is the only bird that can fly backwards. Their wings can be defeated between 12 and 90 times per second, depending on the size and especially the species of sparrows.
There are over 300 species of hummingbirds, although they share some characteristics: they have the most metabolism of any homeothermic animal, they can go into the torper to conserve energy, they can use stimuli in their visual areas. They are very sensitive, show a steady flight - yet strong winds - and can learn vocals through mimicry.
In the most common species, such as Colibri coruscans, the life expectancy is 3 to 5 years. The hummingbird that is known to live the longest is the one who lived 12 years; It rang at the age of one and was re-rated at the age of 11.
The herd of red-necked sparrows, which is famous for living in North America, is known to be the longest sparrows species and can live up to 8 years.
Hummingbirds are found in species that move to warmer areas during the winter months. Once spring arrives, the hummingbird returns to its territory to reproduce. This withdrawal occurs late in the month of March. Males return to their territory approximately eight days before females
When females begin to arrive, males strike in the air to attract them. In this way, they reach a height of about 15 meters before moving at full speed and make patterns and figures in the air. The sound of the male s wings is like a buzzing sound and together with their twitter they arouse the interest of females.
After mating, the female of the sparrows will have little or nothing to do with the male for nest construction and positioning of the eggs. In this way, the adult female hummingbird builds a cup-shaped nest without assistance from the mal
Hummingbird females deposit a maximum of three white eggs in their nests. These eggs are shaped like coffee beans or peas, in which the smallest eggs are deposited by any bird of the world.
Sometimes a female can lay a single egg, but rarely deposit more than two. This is because there are two numbers of offspring that can take care of a female. If there were three of them, they would have died at an early age.
Hummingbirds, like humans, are considered an altruistic species, that is, when they are born, they are completely dependent on their mother for long periods of time to survive.
In this way, the maximum height of two centimeters to a baby at birth and the safety of body temperature and weaning will depend on the mother for several days.
