If you live in the Cincinnati area, keep your eyes out for a large, brown, social bird.
Tucson, the zoo's Harris's Hawk, flew off during a Wings of Wonder demonstration on Sunday and hasn't been seen since, said Cincinnati Zoo spokeswoman Tiffany Barnes.
The bird was born in captivity and may approach humans if she gets hungry, Barnes said.
"They're very concerned," Barnes said of Tucson's handlers. "She's relatively young."
So far, there have been no reports of large birds around the zoo, an emergency dispatcher with the city said Tuesday afternoon.
A Harris's Hawk is a medium to large bird of prey that eats smaller birds, lizards, mammals and large insects. Its habitats include sparse woodland, semi-deserts, marshes and mangroves. Most live in the southwestern United States south to Chile and central Argentina.
