A cardinal that appears to be half-female and half-male was recently spotted in Pennsylvania.
Jamie Hill, a birdwatcher for 48 years, documented the unusual sightingin a Facebook poston Sunday.
"I had a once-in-a-lifetime, one in a million bird encounter!" he wrote.
A friend of Hill's had told him about an "unusual bird" seen at a bird feeder in Grand Valley in Warren County.
The creature was bright red like a male cardinal on one side and brownish white like a female on the other.Hill flocked to the location to see the northern cardinal for himself — and immediately recognized it as a bilateral gynandromorph, meaning one side of it is male and the other female.
