Attempted forced copulation by an immature Red-winged Blackbird male: Video evidence from the Grand River Grasslands of Iowa and potential explanations
Forced copulations are a type of sexual coercion that typically occurs when the fitness interests of males and females are in conflict. Forced copulations are rare in most species of birds, and there are only a few reports in passerine species. Here we report the first published observation of an immature Red-winged Blackbird Agelaius phoeniceus male attempting a forced copulation on a nesting Red-winged Blackbird female. We describe the behaviour and discuss potential explanations and implications for our observations.
