A lot of hawks
From Lamar to the Oklahoma boarder I saw 5 Red-tailed, 2 Ferruginous and 2 unidentified (sitting with sun behind them as I drove by)in this 80 mile stretch, a pretty good hawk/mile ratio.
Though this blog deals with southeast Colorado, I have to report a drive I took just a short distance from Colorado. I drove 19 miles south of Colo to Boise City, Oklahoma. Then I turned east on US64 to Guymon, Oklahoma. In that 60 mile drive I saw 4 light Ferruginous Hawks (3 imm and 1 ad), 2 Red-tailed Hawks and 3 unidentified hawks (too distant)--that's an even better hawk/mile ratio. I believe many of these (and those above) hawks were migrating. This particular stretch of highway has a good deal of what appeared to be native gras/mile frequency. sland.
I also had a male Ring-necked Pheasant fly across the road in front of my car, causing me to slow to avoid hitting it.
