This is a shot I took back on January 7, 2016, at the Ridgefield NWR, in the Ash tree forest. I’m not great at wren identification but I’m thinking this one is a Bewick’s Wren, with it’s pure white eyebrow. The bird was climbing around this portion of the tree when it stuck its head out of the tree cavity.
