Representatives of the genus of the goldfishes living on the meadows are famous for greenfinchs ordinary. This little bird differs fervent trill, which bestows on everyone. Spring becomes especially pleasant at times, filled with a chime of bird polyphony. The singing of the greenfinch is so resonant that it seems that it is she who awakens nature and calls spring to change the winter cold. Anyone who has managed to see a greenfinch will no doubt say that this bird stands out not only for its trills, but also for its glorious plumage. Although it was for the voice of a century ago that it was often called the canary people. However, the bird has nothing to do with this species, since it has its roots in the family of finches. This fact is confirmed by numerous studies of ornithologists.
Bird description
The appearance of the bird correlates with its name, because it is the characteristic plumage of bright yellow and green hues that is characteristic for it, which has acquired an olive tide in the sun, which was the cause of its name. The usual “robe” for a bird often has a rim along the wings of a contrasting yellow color.
According to the body size, greenfinches are small-sized birds. For clarity, they are compared with sparrows, which they barely exceed in size.
What other distinctive features are peculiar to birds of this species? Firstly, greenfinches are owners of a rather large head, a thickened beak, painted in light colors, and a dense body. Secondly, the tail of the bird is narrowed and has a darker color. If we look at individual feathers, we can note the heterogeneity of the distribution of colors on them: by the end they become lighter. The bird's eye iris is colored in various shades of dark colors. The weight of an adult individual does not exceed 35 g, the length of the body often varies depending on the subspecies, in general, reaching 18 cm.
The distribution area of birds
Representatives of this species participate in seasonal migrations, which they resort to due to the need to wait through the winter season at southern latitudes. As noted earlier, bird singing distinguishes it from other birds. Hear the voice of greenfinches can be in the early months of spring. However, the greatest activity of the birds is reached in April and May, which is due to the onset of the mating season, which is important for any living organism. The musicality and melody of singing is achieved by a bird through the skillful alternation of trills, chirping and chirping. The length and sonority of the voice can create the impression that the greenfinch is not in a hurry, sings monotonously.
Such singing begins male individual. In the pre-dawn hours, the male takes off to the highest branches of the nearby tree and loudly leads his melody.To attract the attention of trills and chirping of the bird, they are accompanied by take-offs that raise it above the foliage. In this way, the male demonstrates the diversity of color plumage. If birds eat, their roll call is a low whistle.
Nutrition and breeding features of birds
Food, part of the diet zelenushek, indicates their simplicity. The basis of food birds is popular among people who are fond of veganism, germinated wheat. In addition, birds are happy to peck seeds, grass and buds. Occasionally they pay attention to insects. If a large seed is found, then before eating it, representatives of this species will first carefully peel it, reducing it in size. If possible, the birds do not neglect treats, the favorite of which are juniper berries.
With the onset of spring, the birds start breeding. Nest construction is done by females. Their birds are placed on the trees. The main condition that the birds try to observe when choosing a place for the future nest is its distance from people. That is why the nests of greenfinches can appear at about 5 meters from the surfaceland. The shape of the nest is like a bowl, woven from small twigs and roots, covered with grass, leaves and moss. In the created nest, the female greenfinch lays eggs painted in light colors with brown specks, the number of which does not exceed 6 pieces. The incubation period of greenfields takes about 14 days. Feeding the female is engaged in the male. After the birth of chicks, the extraction of food and the search for food falls on the shoulders of the male too.
Flight of birds
In March, the birds are preparing for the spring flight. In the habitats of the Zelenushka populations during this period, loud trills are heard, signifying a quick migration of birds. During June and July, individuals are grouped and in flocks looking for food on the outskirts of cities, where forests have grown and fields are spread out.
The main flight is accomplished by green zealots, like other species, in the autumn period. Usually, migration occurs in September or October. A rare case is a flock of birds, continuing the "journey" in the winter months. The main criterion for choosing a new habitat for birds is the amount of food. During migration, greenfinch survives a molt that lasts for three months.
Life in captivity
There are precedents for catching zelenushek people. Her resemblance to the canary and the clear voice often became the cause of detention in captivity. The trusting birds, called “forest canaries”, are easy to tame, live peacefully in a cage. The period of adaptation of the bird to "captivity" lasts several weeks. Its ending can be judged by the fact that the bird begins to sing. It is easier for them to adapt if they live in a cage with other members of their own species or other friendly birds that do not threaten the life and health of greenfinches. The Zelenushkas themselves are distinguished by their loving nature. They do not quarrel and get along easily with any neighbors.
They feed the birds finely chopped fruits, cereals or mixtures of grains, seeds of plants, as well as berries. Note! It is important that feathery pets always have clean and fresh water, as it is an essential component of the normalization of the digestive system.
On average, birds live for a long time - the life span of greenfinch reaches 8 years. However, this directly depends on the quality of the conditions that the owners create for the bird living under their supervision.If you take care of the bird, without neglecting the important rules, it will be able to please you for 12 years.
Interesting Facts
