This annual, international event was developed and promoted by Cornell Lab of Ornithology in collaboration with National Audubon Society in 1998. To participate you can join us on our winter bird survey hike. Help us make Ohio a top contributor this year! We will meet at the Aurora Sanctuary at 9:30 in the Bretschneider Park parking lot a few hundred yards east of Page Road on the north side of East Pioneer Trail in Aurora (896 East Pioneer Trail)
