The rounded tail and the rictal bristles extending more than half way over the base of the bill indicate an identity of Chihuahuan Raven, a species not yet on the CFO's official bird species checklist for Larimer County. In recent years, there have been a handful of undocumented reports. In the week of this sighting, several groups of raven had been seen moving around the town of Fort Collins, which is uncharacteristic of the foothills-dwelling Common Ravens. Some of these groups were moving northward, including this photographed individual, which we tracked for over a mile flying north over the plains west of Wellington, about 30 miles from the Wyoming border.
