Right now it’s High Season for observing peregrine falcons in southwestern Pennsylvania. Most are still courting and conspicuously guarding their territories. But by mid-April they’ll become secretive and hard to find as they incubate eggs.
When a peregrine shows up unexpectedly in March I’m keen to find its nesting territory. On Saturday 14 March an immature peregrine (above) caught my attention at Bear Run Boat Launch at Moraine State Park when he flew in and landed in a tree. He was hunting for ducks and (I think) too young to nest.
We’ve had better luck with peregrines in the established territories — 11 of our 12 sites this month.

Activity in the region:
Cathedral of Learning, Univ of Pittsburgh:
Ecco and Carla nest exchange, 18 Mar 2026 (screenshot from the National Aviary falconcam at Univ of Pittsburgh)Carla laid her first egg of 2026 yesterday morning, 18 March. For the rest of the day she and Ecco took turns making sure the egg did not freeze.
In the 4.5 minute video below Ecco is on the egg when he hears Carla arrive off camera. Watch their postures and listen to Carla’s unusual vocalizations (she almost sounds like a goose at one point). By the end of this clip it is clear that she’s telling him “Time for you to go.”

East Liberty peregrine coming in with prey, 9 March 2026 (photo by Adam Knoerzer)The East Liberty Presbyterian peregrines have been very active lately, particularly when the weather is fine. Adam Knoerzer stopped by on 9 March and saw the male bring in food for the female. She appears to be the same female, 3rd year in a row. On Sunday 15 March he saw “Lots of acrobatic tandem flying from the E Lib pair, loving this wind.”

And a Big Thanks to Jeff Cieslak who has monitored the majority of these sites(!) and for allowing me to use his photos.
