My friends at Brandywine Ace Pet & Farm (the hardware store at the intersection of Route 926 and Pocopson Road) wrote to tell me that they hold a "bluebird chat" at the store every other Wednesday at 10 a.m. (There is one on July 19.) It's a roundtable discussion led by Ken Liester from the Pennsylvania Bluebird Society. Those who attend qualify for discounts on bluebird houses, feeders and seed. No registration is required.
I probably shouldn't mention cats and birds in the same item, but this hardware store offers a wonderful selection of cat food, including the aptly named "Fussie Cat," which Clarence prefers paws-down over any other brand of canned cat food.
