PITTSBURGH — Three new residents are living on the 40th floor of the University of Pittsburgh's Cathedral of Learning.

The newest members of the university community are three peregrine falcons that hatched Wednesday.

The National Aviary's director of conservation and field research, Todd Katzner, says that minutes after the white fluffy birds were born the two parents were in the nest, keeping the chicks warm as egg shells flew about.

The aviary has a camera trained on the university nest. Footage can be viewed online at www.aviary.org.

Peregrines became endangered decades ago due to the use of pesticides.
