Male American Redstarts

Warblers — small, active, insect-eating birds — are often referred to as the “butterflies of the bird world” due to the striking breeding plumage of many of the males.  One warbler that’s hard to overlook due to its brilliant orange and black plumage is the male American Redstart.  Like most warblers, it is a very active feeder, flitting from branch to branch looking for insects.  However, it also occasionally feeds like a flycatcher — perching and flying out to capture insects in mid-air, giving you the opportunity to get a good look at it.

The breeding behavior of the American Redstart is of particular interest, in that not only is the male occasionally polygamous, as are many other bird species, the two females he mates with at the same time do not nest in the same territory.  The male holds two separate territories that can be separated by as much as a quarter-mile.  The male begins attracting a second female after the first has completed her clutch and is busy incubating the eggs.  Perhaps the bird world would benefit from a “Me Too” movement.
