Pa. aviary hoping for penguin mating

Pittsburgh -- Officials at the National Aviary in Pittsburgh say they're hoping a pair of African penguins will mate now that the species has been declared endangered.

The institution is a national leader in protecting the species but has never had a birth at the facility, the Pittsburgh Post-Gazette reported Wednesday.

The species, which has declined from 141,000 about 50 years ago to 25,000 today, was officially declared endangered by the U.S. Fish and Wildlife Service Sept. 28 and by an international conservation body in June.
