Gary Weston and I returned to Boulder County continuing our search for Chihuahuan Ravens. Our search centered around Valmont Reservoir area and northeastern Boulder County. Again we gathered many photographs, video, and audio (to be studied later).
We cannot say that we found any Chihuahuan Ravens.

Bryan Ehlmann and I returned to Boulder County in search of prospective Chihuahuan Ravens. We photographed many ravens, videotaped their flight patterns to study later, and recorded audio whenever possible.
Today’s 8 hour search focused around Lafayette, Louisville, and Superior (southeastern Boulder County).
We cannot say that we found any Chihuahuan Ravens. Several dozen Common Ravens and many American Crows were picked out. Perhaps after we study our collections?
We missed the White-throated Sparrow at Waneka Lake (Greenlee Preserve) also.
