5-23-17: American Redstarts in Porcupine Mountains Wilderness State Park, MI,U.P.




Male American Redstart





The males sometimes have two mates at the same time.  While many other polygamous bird species involve two females nesting in the same territory, the redstart holds two separate territories that can be separated by up to a quarter-mile.  




Female American Redstart
The male begins attracting a second female after the first has completed her clutch and is incubating the eggs.
