Nauvoo 4/29

12:00-3:00: I continued my day off with a trip out to Nauvoo, near fish creek. Blue bird boxes produced one nest of 5 eggs. House wren also using one or two boxes. Heard scarlett tanagers, saw barn swallows, tree swallows, sarp-shinned (could I ID a merlin??)heard an oven bird but could not locate. He seemed to be up a bit too high in a tree so I question this ID.
