I am finally posting the rest of our trip details, so I don't get too behind on posting my blogger updates.
On November 25, Alex and I drove to Rokcy Mountain Arsenal NWR. Here we joined a bus tour of the refuge, since most of the refuge is not open to the public. Highlights of the trip were numerous ferruginous hawks circling over prairie dog colonies, in addition to a prairie falcon, that flew right over our bus. Alex spotted a snow goose in a flock of canada geese, and the volunteers that were giving the tour said they had never seen one on the refuge (rare in this part of CO). Mule deer were also in rut and were everywhere. At one point, we had to stop the bus and wait for one to get out of the road; he could not be concerned with the bus, as a female mule deer was on the other side. We also saw shovelers and green-winged teal, the first on our trip.

Next we travelled to Two Ponds NWR. This is a very small refuge in the middle of town, but still had a few good birds. This american kestrel did not seem to be concerned by our presence. Walking along the trails, we spotted house finches, blue jays, and white-crowned sparrows.

We also spotted this partial alabino red-tail hawk. From below, it looked very normal, but its upperwing coverts were mostly white. Alex has better photos here.
