Have a nice day to all and thanks for your comments. JYB
A boldly-patterned warbler of second growth woods, the American Redstart frequently flashes its orange and black wings and tail to flush insect prey from foliage.
Cool Facts
The American Redstart is not particularly closely related to the Painted Redstart and the other redstart warblers of the Neotropics. They all are similarly patterned and forage in similar ways, flashing their tails and wings to startle insect prey. In other parts of the world other unrelated species of birds look and act similarly, such as the fantails of Australia and southeastern Asia.
A young male American Redstart resembles a female in plumage until its second fall. Males in the gray and yellow yearling plumage will try to hold territories and attract mates, singing vigorously. Some succeed in breeding in this plumage, but most do not breed successfully until they are two years old.
The male American Redstart occasionally is polygynous, having two mates at the same time. Unlike many other polygynous species of birds that have two females nesting in the same territory, the redstart holds two separate territories up to 500 m (1,640 ft) apart. The male starts to attract a second female after the first has completed her clutch and is incubating the eggs.
