We have a large winter crow roost in Springfield. I have estimated 20000 birds for our CBC in several years but that may be low. The crows have been roosting here in Springfield for at least 40 years. The city is trying to find more information on crow roosts. I would like information on where other winter crow roosts are in Ohio. If anyone knows where there are other large winter crow roosts in Ohio would you please send me the general location and estimate of numbers.
