Domestic rooster (Gallus gallus domesticus)
The Zoo is home to one rooster, Jerry, who came to the Zoo in 2011.
Status in the wild
IUCN Least Concern, though the species in the wild has never been quantified.
Domestic chickens are found throughout the world in captivity.
As omnivores, these birds eat a lot of grains as well as soybeans, corn, grass, worms and insects.
- All chickens are descendants from one type of bird, the red jungle fowl (Gallus gallus). They were first raised in captivity at least 5,000 years ago.
- Dominance behavior is displayed by the raising of the head and tail. Other aggressive or dominance behaviors are wing flapping and crowing.
- The red jungle fowl lifespan is about 25 years, but the Phoenix rooster, like many domestic roosters, can live up to 10 years.
