House Wren (Troglodytes aedon), photographed on Bodega Head on 14 September 2014
I loved the subtle barring on the wings. The Birds of North America account said the coloration of the upperparts could be described as brown, cinnamon olive brown, or "Prout's brown." I wasn't sure what Prout's brown was, but eventually located a definition that said it was a dark olive brown. Which do you think is the best match?
