The crown Waldsänger ( Setophaga coronata , Syn. : Dendroica coronata ), also called Myrtenwaldsänger is a small bird from the kind of tree Waldsänger ( Setophaga ) in the family of Waldsänger (Parulidae). The species is partly as conspecific with the Audubonwaldsänger ( Setophaga auduboni viewed). Both forms meet on their way to the breeding areas in the mountains between British Columbia and Alberta , where they both mix ( hybridize ).
features
The male crowned warbler has a yellow crown spot on the head and yellow flanks. In the eastern form the throat is white, in the western form it is yellow. The back is gray-blue with black spots. The chest is spotted black, in the western form it is a uniform dark gray. The gray-blue wing-coverts are spotted white. The tail feathers have white tips.
The female has duller plumage in both forms. The yellow spots on the flanks are only faintly visible. The top is light brown in the front area. There is a white ring around the eyes.
In both sexes, the rump is yellow (giving its name in English: Yellow-rumped warbler).
