The National Aviary, which runs a livestream camera of the nest, says Red was admitted to the Humane Animal Rescue of Pittsburgh's Wildlife Center for treatment, where he was also diagnosed with elevated lead levels.
Red, a young peregrine falcon that hatched in the nest on top of Pitt's Cathedral of Learning this spring, is in the care of humans after he apparently suffered a collision and then tested positive for lead exposure.
The National Aviary has two baby Guam Kingfishers, known as sihek in the indigenous CHamoru language. The male Guam kingfisher hatched on April 19, while the female hatched on May 12. On May 27, the male chick took his first flight.
