The Solitary Tinamou ( Tinamus solitarius ), also called Einsiedlertao or Macuco-tinamous bird called, is a species from the family of Tinamous (Tinamidae). It is native to two subspecies ( T. s. Solitarius and T. s. Pernambucensis ) in central Brazil , in southeastern Paraguay and in northeastern Argentina .
description
The adult birds reach a size of 42.5 to 48 cm. The weight is up to 1500 g for the males and up to 1900 g for the females. The head is black. The black top is tightly banded. The chest is gray. The belly is light. The back and wings are yellow-brown with dark banding. The top of the young birds has white spots of varying density, especially on the wings. The chicks are cinnamon in color. In the subspecies Tinamus solitarius pernambucensis , the color tends to be bright yellow. The banding is more pronounced on the neck. His voice consists of set monosyllabic tones that are sometimes reminiscent of telephone tones.
Habitat and way of life
The greyish tinamu prefers moist, warm tropical and subtropical forests. But it can also be found in regions with cold seasons on sandbanks. He avoids virgin forests with undergrowth and with fragmented and inconsistent pasture areas. Each bird claims a territory of 30 hectares of primary forest. It occurs at altitudes from 0 to 1200 meters above sea level. Its food, which it prefers to eat in the evening, consists of seeds of the rhombus family, milkweed family, bottle tree family, berries and other small fruits as well as beetles and other invertebrates. Occasionally it also preyed on frogs. Gray-tipped tinamus are kept in human care where they can reach an age of twelve to fifteen years.
Rearing boys
The gray tine tinamus have a polygamous way of life. The choice and construction of the nest is the job of the male. The nest is in a hollow on the ground and is padded with leaves. Six to fourteen greenish-blue to turquoise-colored eggs are laid in an interval of initially one day and then three to four days. The male incubates the eggs for 19 days. The chicks' flight feathers begin to grow on the second day. The juvenile plumage comes after 25 to 28 days and after three months the birds are fully grown.
Danger
The gray titinamu has become quite rare due to overhunting and habitat loss. In 1971 there were only 100 specimens of the subspecies from Pernambuco. It can only be found frequently in individual protected areas. Large parts of its living space are shrinking more and more, which is due to the expansion of cities, roads, agriculture, the population and industrialization.
