About the Osprey Nest at Oregon Law

Eugene is known for its rain and clouds – but not for fish dropping out of the sky. Osprey legend is that in 2014, while the birds were nesting at the historic Hayward field, they dropped their lunch – which happened to be trout – on unsuspecting runners. It was at that point in time that the University had the nest moved across the street to its current location at Oregon Law. The Osprey’s soon adapted, and within two weeks, they moved to their new nest.

The nest currently rests on a 52-foot-galvanized steel lamp post retrofitted to be a platform. In 2018, the School of Law installed a video camera atop the osprey nest perch to offer a bird’s eye view in real time of the nesting osprey. This unique view was made possible through gifts by friends and alumni in honor of retired Dean Margaret “Margie” Paris, the first woman to hold the deanship at Oregon Law. Since being installed, more than 170,000 visitors have viewed the live stream.
