Pretty neat and extremely rare.
The bird was identified as a Rose-breasted Grosbeak. Male and female Grosbeaks are distinguished by their color: males have pink "wing pits," while females are yellow-brown.
The sides of this bird's body were different colors.
This genetic variation is known as gynandromorphism ("gyne" is Greek for female; "andro" means male, and "morph" means variety).
Due to its rarity, scientists don't know much about how gynandromorphism affects the bird's life.
"There probably aren't any advantages to it," Lindsay said. "It will definitely impact its ability to mate. We don't know if that female side has a functional ovary. If it does, and it is able to attract a male mate, it could reproduce."
