Families on their Sunday walk can stop by to learn how bats eat huge numbers of insects, pollinate plants including human foods and reseed rainforests, why one in five mammal species is a bat, and why many bat species are in decline and how people can protect their habitat. It is a drop-in table, so children can stay a few minutes or longer between 10 am and 2 pm, with no registration. The program is free and listed for families and scouts. ## Similar picks in Philadelphia - [Skulls, Bones, Horns and Antlers — Ridley Creek State Park](https://grassyknees.com/philadelphia/activities/skulls-bones-horns-and-antlers-ridley-creek-state-park--listing-26588d695ce3e09bed348a75) — Sat, Oct 31 · 10:00 AM – 2:00 PM · Ridley Creek State Park — Multi-Use Trail Outdoor Classroom (stone bridge below the mansion), Newtown Square · Free · checked Oct 20.
