Two special guests will make Carrie Barron’s presentation a fitting climax to the third annual American Birding Expo on Oct. 1 at the Greater Philadelphia Expo Center, 100 Station Ave., Oaks, Pennsylvania.

Joining Barron during her presentation on Birds of Prey, set for 2 p.m., will be an eastern screech owl and a great horned owl. In her program, Barron, assistant director of the John James Audubon Center at Mill Grove, Pennsylvania, explores the adaptations that have made these birds the “lord predators of the sky.” These birds are unrivaled when it comes to finding food because of their eyesight, feet for holding prey and beak for tearing into the flesh.

After a guided nature walk at 7 a.m., attendees will move inside the Expo hall at 10 a.m. with the start of the day’s festivities. Children can enjoy a coloring station, participate in a birding scavenger hunt or try their luck at a game of Nature Wheel-of-Fortune. They can also get a real “feel” for the nature of things at the Please Touch Nature Table. Ages 16 and younger are admitted free.
