The Buzzards of Hinckley. Every year in the spring, the swallows return to Capestrano, and the buzzards (turkey vultures) return to Hinckley, Ohio. Oddly enough, the buzzards seem to return on the same day each year -- March 15th. The town of Hinckley celebrates with a pancake breakfast, official buzzard sitings, and a lot of other festivities. The event draws about 2000 bird enthusiasts per year. We hiked in Hinckley Reservation on the 14th, a cold and misty day. Up in the treetops the buzzards sat, drying their wings and waiting for their next meal.
