Bird of the Month

March Bird of the Month: Gynandromorphic Birds

This past February, a very unusual Northern Cardinal was spotted in Erie, Pennsylvania. Its right side is brilliantly red, while its left side is a modest brown, with both sides perfectly split down the middle. The reason for the color split is remarkable; the left side is biologically female, while the right side is biologically male. Genetically, the two halves are as closely related as brother and sister.
