The Brookfield Zoo says a 48-year-old female gorilla named Alpha has died from kidney problems.Alpha was born in the wild and brought to Brookfield in 1963 when she was about two years old. Over the last few weeks, keepers at the zoo noticed a change in her behavior.

Alpha was euthanized after zoo veterinarians discovered that she was in the late stage of kidney failure due to her advanced age.

She was one of the oldest female gorillas in a North American zoo.
