Abstract
The majority of female Red-winged Blackbirds (Agelaius phoeniceus) given exogenous estradiol responded to playback of male song with copulation solicitation. Nine females given no exogenous estradiol all failed to give any displays in response to playback. We conclude that estradiol treatment is necessary to elicit response to playback in captive female Red-winged Blackbirds. Given the task of discriminating full conspecific song from a partial song, females treated with a double dose of estradiol showed a degree of discrimination nearly identical to that shown by females treated with a single dose. Variation in estradiol dosage appears not to have a strong effect on discrimination.
