As I have been out owling before dawn or after dark in Creston in open grassy areas, usually near water, I have been regularly hearing an unknown bird sound. It is often heard overhead, usually meandering around. It is possibly a hunting owl. It is high and nasal, a bit like a high Caspian tern sound. I made a recording with my phone that is a bit fuzzy. You may need headphones to hear it properly. The sound begins right away, but blends into a "laughing" mallard in the background (it is not the mallard--that was in a different direction). Any ideas? I had considered owls, but the sound doesn't match any recordings I have been able to find. I also considered Bittern, but given one of the locations where I heard it, this is unlikely. Barn owls are numerous here, and I have heard them make an unexpected variety of calls. I am wondering if that is a possibility. I've also considered Barn and Short-eared owl, but no recording matches.
The recording is at the bottom of this ebird list. Any ideas?
Hey Jon. Yeah, the phone mic picks up itself quite nicely. I actually mean the sound around 1 second, just before the Mallard comes in. It may also repeat itself later (I don't have headphones with me at the moment to confirm).
