Watch the Progress of the First Peregrine Falcon Egg Laid at the Cathedral of Learning

In early March, Hope, a female Peregrine falcon, laid her first egg of the season at the University of Pittsburgh’s Cathedral of Learning nesting site in Oakland. 

Peregrines typically lay their eggs two days apart. The male and female take turns incubating the eggs, with the female incubating more often than the male. However, the parents won’t start incubating until the second-to-last egg is laid.

Peregrine falcons continue to be listed as an endangered species in Pennsylvania because their population has not recovered sufficiently at their natural cliff nest sites. There are currently eight nesting pairs in the Pittsburgh region, all of them residing on human-made structures.

“Over the coming days and weeks, viewers from around the world will be logging on to await the appearance of additional eggs, and, if all goes well, the hatching of the chicks,” said National Aviary Ornithologist Bob Mulvihill. “The FalconCam provides remarkable insights into this species, giving viewers an up-close view of these raptors as they develop, mature, and fledge.”
