While I was photographing the Pine Grosbeaks, I noticed movement out of the corner of my eye. It was this Brown Creeper foraging up the side of a tree. It is so well camouflaged that, without the movement, I might not have noticed it. Brown Creepers always fly to the bottom of a tree and work their way up to the top, often circling the tree as they go. They have stiff tail feathers to brace against the tree and their sharp, decurved beak is perfect for plucking small insects and insect eggs from the crevices in the bark.
