1978 Walter D. Koenig Melanerpes formicivorus Santa Barbara, 27 m. W. Durango, Durango, Mexico, elev. 7900' (18 January) logged sometime ago). The shrubs were primarily a Manzanita with some other various kinds mixed in. I only saw 2 kinds of pine, both fairly common and codominant. The first was quite a lot like Yellow Pine, and is most likely Montezuma Pine. The bark is identical, and it was in the bark (and dead wood) of this species alone that I found storage holes and stored acorns. This pine has 3 rather long needles per fascicle, rather large cones that grow in clusters (2+4) around the limb, and is rather densely leaved. The second pine has darker bark, shorter needles, and small cones, looks rather like a lodgepole pine, and was not used at all by the woodpeckers. As for the oaks, there appeared to be 3 species. The first had leaves very like a Golden Oak, but had very small acorns [→ O like so]. It was quite common, far more so than either of the other 2 species. Every stored acorn I looked at (≈50) was most likely from this species, and all storage holes noted were correspondingly minute. I did not notice any trees with acorns still in the canopy, though some had quite a few on the ground below them. The second species was present in fair/poor numbers, but included a few large individuals. It looked rather like a Blue Oak, especially the bark and the leaves, which were somewhat large for your average douglasii however. No acorns were found. The third was
