Where do round-fingered dwells live?

Round-bottomed moths belong to migratory birds that migrate over long distances. The nesting period of these birds takes place in the Arctic, sometimes in more southern territories. Habitat does not extend further south than the 57th parallel of north latitude. Wintering at the fishermen takes place exclusively in the tropical zone. You can regularly meet birds of this species in Italy, when they fly across this country, they rather rarely spend the winter in this area.

Their finch nests are usually settled in the tundra, as well as in the forest tundra. Basically, as a place to live, these birds choose the shores of lakes, as well as marshlands. At the time of wintering birds move to other territories, but they can be found most often in the open sea or on the coast.

How do babies live and behave?

During the nesting period, these birds usually create colonies of a small number of individuals.Nests are mainly settled in low plants, as well as in moss. As a litter, these birds use different leaves and stems. The period of egg laying at the spearheads usually falls on time from the beginning of May to July. On average, females lay 4 eggs in one laying, eggs have an olive tinge and dark spots. After the females lay their eggs, they immediately fly south. Hatching eggs predominantly males, in time, this process takes up to three weeks. Broods have only one per year. After hatching, the chicks independently feed themselves. Already after 20 days, the offspring can fly and swim independently. Males leave offspring as soon as chicks begin to move independently. After this, broods tend to fall apart.

A distinctive feature of this species of birds is how easily they behave in flight. Ditches, besides, love to float. The round-nosed swimmers have a very creaky voice, and they are distinguished by their trust. In the menu of these birds are mostly invertebrates that live in the water. Interestingly, these birds are excellent swim, and can also easily dive due to the rims on their fingers.The process of extracting food comes down to the fact that the little pearl rotates around its axis and stirs up the water around itself. This greatly facilitates the process of capturing invertebrates.

The voice of the representatives of this type serves in different situations, and the cries can be completely different. Most often you can hear from them something similar to the "chirk". Chicks, when worried about something to call a parent, usually shout more softly "chshshshk." When the male seeks to attract the attention of the female in the mating season, he can use the cries of various modifications. It is also important to note that a loud flutter has a certain value in communication between birds, both during takeoff and during landing.
