The Barbara J. Mapp Aviary Education Center provides educational programs, allows up-close observation of non-releasable birds of prey, and offers a bird's eye view of the surrounding hillside and wildlife. In addition, interpretive displays on venomous snakes, non-venomous snakes, and turtles are available inside the main building. Constructed as a boardwalk, nestled in the natural area, the facility is wheelchair accessible. The nearby amphitheater provides outdoor seating for our ranger-led educational programs.

Aviary Project Update

The Barbara J. Mapp Aviary Education Center project consists of two phases.

  • Phase I – 550-foot boardwalk and five pens that will be home to four non-flighted raptors and one non-flighted American Bald Eagle. Phase I is complete thanks to a recent $50,000 matching grant from Barbara J. Mapp Foundation and many generous donors.
  • Phase II – a netted Eagle aviary that will house two flighted American Bald Eagles. Friends of Radnor Lake is actively fundraising by seeking grants, corporate partners and private donations to raise the final $100,000 to complete the Eagle Aviary, and related education programs and materials.
