Yellow-rumped Warbler

Female Kron Warbler ( Dendroica chrysoparia )

The Kron Warbler ( Dendroica coronata ) is a small bird in the family of warblers ( Parulidae ), which originally consisted of two different types. For one, this was the eastern myrtle warbler and on the other the western Audubon's Warbler. Both forms take on their way to their breeding grounds in the mountains between British Columbia and Alberta each other, where they both mix ( hybridize ), so that both species were summarized by this observation to one species.

Features

The male Kron Warbler has a yellow Kronfleck on the head and yellow flanks. In the eastern form, the throat is white, in the western form it is yellow. The back is the eastern Kron Warbler at the front of gray blue, in the rear of black gray brown to almost black. On the gray-blue elytra he has white spots and the tail feathers are yellow stripes and white tail tips. The front area at the western Kron Warbler is dark gray. The female has a duller plumage in both forms. The yellow spots on the flanks are only slightly visible. The top is light brown in the front area. To the eye there is a white ring.

Nutrition

They feed mainly on insects. In winter, fruits and berries are eaten.

Reproduction

During a breeding season in an upwardly open cup-shaped nest, two nests are often raised. A clutch consists of four to five eggs, which are hatched in a period of twelve to thirteen days. After about ten to twelve days the chicks fledge.
