This condor nest, known as the Pole Canyon nest, is located in a remote canyon near the Hopper Mountain National Wildlife Refuge. The parents of the chick in the Pole Canyon nest are mom #563 and dad #262. Dad #262 was laid in 2001 and was the first viable egg laid in the wild since the reintroduction program began. He was actually one of two eggs laid to a trio (male #100 and females #111 and #108) but was brought into captivity to ensure proper incubation. He hatched at the Los Angeles Zoo and was released back to the wild a year later in 2002. Mom #563 hatched at the Oregon Zoo in 2010. This is their first nesting attempt together, but both have nested previously with mates who are now deceased. A single egg was laid in this nesting cavity, and the chick hatched on April 10, 2019.
