The color red will elicit an "aggressive response" from a male red-wing. If the male bird enters another red-wing's territory, he will re-arrange his wing feathers so the red part will be covered. Red-wings return to the same nesting place year after year. I have read that one male will nest with three or four females simultaneously. I have never observed more than one female in a male's territory, however. The "aggressive response" includes a display of the red on the wing and a characteristic series of calls. If the latter are recorded and played back to the male red-wing, it will make him think another male is in his territory and cause him to display.
