In spring, the south of Brazil receives hundreds of species of migratory birds, each one with its characteristics, habits and color compositions, which further beautify our sky.
One of these species is known as the swallow-tailed kite, with the scientific name Elanoides forficatus. They are birds of length between 52 and 66 cm, with wingspan between 120 and 135 cm, being the females larger than the males. The most striking feature is the forked tail, which in flight resembles the shape of a scissor, justifying its popular name.
Despite its considerable size, its diet consists of insects, mainly termites, ants and dragonflies, small lizards, frogs, snakes and other smaller birds, as well as some fruits. They inhabit the edges of forests and fields, usually in groups that can reach up to 30 individuals, being one of the most sociable birds of prey.
Between April and July, populations are concentrated in the Amazon region. In August, migrations to the southeast and south of Brazil begin, in groups of up to hundreds of individuals. Between September and February it is possible to find them in Rio Grande do Sul, in the territories of the Atlantic Forest.
The climatic conditions of this season and the availability of food support its reproductive period. The nests are high up in the trees, usually with two or three eggs, remaining incubated between 24 and 28 days. Both parents take care of the young, which leave the nest at six or seven weeks. As of March, the large groups return to the Amazon.
With these migratory movements, the species contributes to the environmental balance in the regions of occurrence, controlling the growth of populations of various organisms that, in excess, are harmful to environments and their inhabitants.
This year, at Seta Estância Velha, we were able to admire this bird in its migratory season. Clear sky days are ideal for your sighting.
