Pittsburgh bird watchers said a bald eagle is believed to have hatched in the city for the first time in more than 200 years.

Ornithologist Bob Mulvihill and other monitors who have spent two months monitoring a mated pair of bald eagles said the male eagle was seen carrying a small mammal to their nest Sunday and feeding it to what they believed to be a newly hatched eaglet, the Valley News Dispatch, Tarentum, Pa., reported Monday.

The experts said the chick cannot be seen from the ground due to the massive size of the nest, but it is expected to leave the nest in early July.

Peter Nye, a retired wildlife biologist from the New York Department of Environmental Conservation, said the Pittsburgh birth is a good sign for Pennsylvania's eagle population.

"It means statewide that the eagle population is doing well and that there is a good food supply," Nye said.
