Researchers at Powdermill Nature Reserve find rare bird showing male and female plumage

A team of researchers at Powdermill Nature Reserve in Rector caught and banded a rare Rose-breasted Grosbeak gynandromorph on Sept. 24. Gynandromorphs are genetically part male and part female, and in this case, that line runs roughly down the middle of the bird with male characteristics on the right side and female characteristics on the left. Rose-breasted Grosbeaks are sexually dimorphic, meaning that males and females have different plumage colorations.
