Many Oregonians are familiar with Acorn Woodpeckers, which are easily recognizable by their clownish black and white faces, red heads, and noisy calls. They live in social groups and have an interesting mating system that involves multiple males and females sharing one nesting cavity and raising chicks together.
Acorn Woodpeckers also share their food storage systems, called granaries. According to Cornell’s Bird Academy, each woodpecker “…group works together to maintain and defend its acorn collection…reused over generations to store the winter food supply.” Granaries are not rare, but the Touvelle State Recreation Site, which runs adjacent to the Rogue River east of White City, houses an especially impressive one, with thousands of acorns inserted from the top of the tree to the bottom. It is easily found near the parking lot. Drive to the far end of the lot and face the restrooms located at the top of the hill that edges the lot. The tree — a dead trunk devoid of limbs — is located to the left of the restrooms, not far from the curb.
Although not odd, the rest of the Recreation Site is worth a visit. There is an easily walkable nature trail that winds along the side of the river, and then loops through meadows and a seasonal wetland. It is a good place to look for winter birds, swallows in the summer, and the ubiquitous woodpeckers. A nice place to picnic, there are picnic tables and benches. It is quiet during weekdays. A $5.00 entrance fee is charged.
The map (above, left) shows the location of the park relative to Medford via Hwy 62 (from the I-5 exit) or Table Rock Road (from Biddle Rd.) west of the Medford Airport.
To provide some detailed anatomy, the pictures at left and right show views of a section of a granary tree that was felled in Bear Creek Park.
Manor residents can find an even closer granary tree. This tree, located at the side (library) entrance into the Manor Building, has become a beloved natural icon, and a spirited and successful protest was launched when consideration was being given to removing the tree. Granted, the tree is dead and several limbs have been removed or fallen off. Its days are numbered so locals should enjoy it along with the Acorn Woodpeckers that may frequently be seen on the tree. This more humble tree also is pictured below. — Anne
I don’t know that I consider the tree more humble –dilapidated, perhaps. Several views of the RVM granary tree are shown below. Real snacks for acorn-eaters. Who are the other local consumers? Squirrels and other rodents, although they might have trouble getting around the defenses of a “social group” (a.k.a. militia) of woodpeckers. Turkeys especially like the acorns that fall in the streets where the cars crush the shells. And bears. Do woodpeckers attract bears? I don’t know, but if I come upon a tree that has big scratch marks as well as little holes containing acorns, I will probably redirect my nature study to some other location. — Bob
