The beech tyrant ( Empidonax virescens ) is a small insectivorous bird that belongs to the family of tyrants . Like some of their very similar relatives, often only distinguishable by their voice, beech tyrants look out for flying insects from branches, which they then capture with a short but agile flight.
features
The beech tyrant reaches a length of up to 15 cm. The wingspan is 23 cm, the weight is 11 to 14 g. The beech tyrant is characterized by its olive-brown breast and black and white piebald wings.
distribution
The beech tyrant breeds in the east and southeast of the United States and in southeast Canada from the province of Ontario to the Great Lakes area . In winter he moves to South America. During bird migration it can be found from eastern Mexico via Guatemala, Belize, Honduras, El Salvador, Nicaragua and Costa Rica to Panama and on the Caribbean islands such as the Bahamas or Cuba. He moves into winter quarters in Colombia, Venezuela and Ecuador.
Habitat and way of life
The beech tyrant prefers the deciduous deciduous forests during the breeding season. He likes to be near water.
The female builds the relatively flat nest in the fork of a branch, it is lined or held together with spider silk and other fine webs produced by insects. The nest can often be recognized by the fact that individual stalks or nest material hang down on the sticky threads. When the 2–4 young birds have fledged, the female already begins a second brood. Regularly put Brown-headed cowbird eggs in the nests of the book tyrant. But only 16% of the young cowbirds reach the age at which they can leave the nest, which is less than in the nests of other birds.
