The Canada Waldsänger ( Cardellina canadensis , Syn. : Wilsonia canadensis ) is a small insects eating birds in the family of Waldsänger (Parulidae).
Male Canada warblers have yellow underside plumage with a black-dashed and spotted upper breast. The top is blue-gray. There is a yellow to white eye ring around the eye on both sides of the head. A yellow stripe runs from the eye to the base of the beak. The plumage on the back of the face is black. In the female, the plumage is generally more blunt than in the male and the black parts on the breast are less pronounced. They have a thin, pointed beak. Her legs are pink.
The main food consists of insects that are found in the dense undergrowth. Among other things, snails and fruits are also consumed.
They lay their nests, which are open at the top, on the ground or close above the ground. Dense, low vegetation is important for this. Only the female participates in nest building and the breeding business. Grass, lichen, moss and fibers from roots are used as nesting material. A clutch consists of four to five white eggs that are hatched over a period of around twelve days.
The Canada warblers got their name from their first discovery in Canada . However, they are not limited to Canada. Their breeding grounds are located in the humid mixed forests of Canada via British Columbia and Nova Scotia , to Minnesota , Michigan , Connecticut and further south to Georgia . They spend the winter in northern South America , including Venezuela , Colombia , Ecuador , Peru and northern Brazil . Due to habitat destruction and changes in the forest structure, the numbers of the Canada warbler have declined.
