I located the birds nesting in Rich County(Monte Cristo Mountains) while watching the Williamson's Sapsucker's on 7/8/07. Beautifully dainty little birds. Appear to still be in the incubation stage. I was amazed how tightly the nest had been woven together, it appeared as smooth as a tightly woven piece of wool.
