History of Peregrine Falcons at the Cathedral of Learning
Peregrines have nested at the University of Pittsburgh's Cathedral of Learning for 12 years. Dorothy began nesting here in 2002 with her first mate, Erie. In the fall of 2007, when Erie disappeared, another male (Erie II, or E2) showed up. Dorothy fledged a total of 22 chicks in seven years with Erie and another 20 chicks with E2. Her last nesting attempt, in 2015, was unsuccessful, and in November 2015 a new female appeared at the nest box with E2. We assume that Dorothy finally succumbed to the effects of her very old age (almost 17 years old) for a wild Peregrine.
A replacement female for Dorothy, known as "Hope," did not have to come from very far away. She tried, mostly unsuccessfully, to nest at the Tarentum Bridge (about twelve miles away as the falcon flies) for several years. Presumably, E2 somehow made his unmated status known--perhaps with conspicuous flight and vocal behaviors--and Hope decided to join him in Oakland at the Cathedral of Learning. They have been seen courting numerous times on the nest cam, and viewers around the world are very hopeful that E2 and Hope will successfully pair-bond and nest this coming spring!
