John Stump and I spent a morning out birding under gray skies. Birding was good and we had 4 species of gulls: California, RB, Franklin's and Bonaparte's. Rock and Marsh Wrens were at Smith Reservoir. Best of the day was a flock of 9 Mountain Plovers south of Smith (Costilla County) in a bare soil area. This is the largest flock ever recorded here and the second earliest date for the species in the San Luis Valley. Great day out and about.
