The Silberkopf-Breitschnabeltyrann ( Platyrinchus platyrhynchos ) is with a body length of 7.5 centimeters a smaller representative of the family of tyrants .
Appearance
The species has a thick, round head with a broad, short beak that is black in the upper part and white in the lower part. The neck is very short. The back plumage and the head are black. The belly is yellowish in color. The white chin area is particularly noticeable.
distribution and habitat
The silver-headed broad-billed tyrant is found in the rainforests of northern South America and the Amazon region. There, this species inhabits the forest floor and the lower levels of the jungle trees.
Way of life
The birds live together as pairs and roam the jungle in search of insects and spiders. When there is a lot of food, the birds form small groups.
Reproduction
To build a nest, the female uses tree ferns and other plant fibers, which she builds into a spherical nest with spider silk. The nest is created in the forks of higher trees, usually 1 to 2 meters above the forest floor. The female only lays 2 eggs, 2 days apart. The breeding business is done by the female alone. The male supports the young birds, which leave the nest after 2 weeks.
Danger
Due to its further distribution and since no endangerments are known for this species, the IUCN classifies this species as ( Least Concern ) not endangered.
Subspecies
There are four known subspecies:
- Platyrinchus platyrhynchos platyrhynchos ( Gmelin, JF , 1788) - The nominate form occurs in eastern Colombia via Guyana to northern Brazil .
- Platyrinchus platyrhynchos senex Sclater, PL & Salvin , 1880 - This subspecies occurs in eastern Ecuador , eastern Peru , northern Bolivia and the extreme west of Brazil .
- Platyrinchus platyrhynchos nattereri Hartert & Hellmayr , 1902 - This subspecies is common in the south-central Amazon region of Brazil.
- Platyrinchus platyrhynchos amazonicus von Berlepsch , 1912 - This subspecies occurs in the eastern Amazon region of Brazil.
Etymology and history of research
Johann Friedrich Gmelin described the silver-headed broad-billed tyrant as Todus [] platyrhynchos . In 1805 Anselme Gaëtan Desmarest introduced the new genus Platyrinchus for the silver-headed broad-beaked tyrant. This name is derived from the Greek words "platys" πλατυς for "broad" and "rhynkhos" ῥυγχος for "beak". The specific epithet has the same origin. The Latin »senex, senis« means »old person« and refers to the gray hair color of older people. "Amazonicus" refers to the Amazon region. »Nattereri« is a tribute to the Austrian natural scientist Johann Natterer .
