Karen Devens was walking through a wooded area on the University of Florida campus when she saw the bird in late April.
“I’ve seen many cardinals in my life — but apparently not enough,” the South Florida Wildlands Association Facebook post read. “Scientists believe this is a one-in-a-million genetic mutation.”
Other sightings have been reported in Alabama, Florida, Ohio, and Pennsylvania in recent years.
There are only 10 to 12 yellow cardinals in all of North America, according to experts. They have a genetic mutation that causes them to be yellow rather than their classic red. Cardinals live about three years.
