I see that you have not yet photographed a Eurasian Tree Sparrow. It has a very narrow range in Missouri. Sometime when you are in St. Louis with a little extra time maybe you can look for it. It is most usually found along Grants Trail from the southernmost trailhead to Gravios Road. It often is found in Clydesdale Park, which is adjacent to Grants Trail off of Tesson Ferry Road, about a mile from Concord Trinity UMC.
