If you look carefully, you'll spot holes in the trunk. Woodpeckers like this tree because it is nice and soft and easy to make holes in. They store nuts in the holes. Isn't this neat? you get a nice picture session and national geographic education all in one. I should also mention the burn marks on the trunk. These trees are naturally fire resistant since they're full of resins and tannin. Meaning if you chewed on the trunk you'd stain your teeth nasty yellow I think... The acorns this tree produces rely on fire to clear the underbrush, and open up in extreme heat to liberate their seeds unto the nice, clean fertile burnt-out soil beneath. One plant's poison is another plant's... meat? err.
