I thought this might be a Marsh Wren being out here in West Texas but the tail and other marking don't match . However this bird is very small like a Bewick's Wren , it was all over this tree like a woodpecker does digging into creases , branch joints and any other tight spot with that tiny bill . Can anyone ID this for me please ? I took this out at Ft.Davis State park in West Texas . Thanks for any help .
