This is for all you bird call sleuths out there. A bit after dusk, I had a bird in central Illinois respond to a saw-whet tape. It sounds just about identical to the smack call of a Brown Thrasher, and there's a single (what I thought was unreliable) report from earlier this week, but this is a frequently visited spot so I thought it would have been detected by now if it was there. That said, I'm curious if there's any other species this could be. Thanks.
