One more warbler from 2017 files. OK, so the perch is too big for the bird, or vice versa. This was taken from a blind at Laguna Seca ranch, and presumably the perch was a setup intended for larger birds, but this little guy found it. He was probably attracted to bits of suet on the branch, some of which is still visible.
