Here is another telltale bird sign that you can find rather easily in the winter. Any guesses as to what species made these massive marks on this tree? The Pileated Woodpecker is a large, crow-size bird and as such it creates astonishingly huge holes with its big bill. Even though they are conspicuous birds when seen they can be tough to find in the first place because they have such large territories. If you cannot see them flashing by through mature woodlands try listening for their laughing call or finding these reminders of their presence.
