1978 Walter D. Koenig Melanerpes formicivorus 26m.E. El Salto, Durango, Mexico 8650' elev. (18 January) to the car, I heard the definitive kanit (we have yet to have a waka anywhere in Mexico) and I soon discovered a bird near the road. It was a ♀, and she obligingly flew down low (7' off the ground) into an oak on a dead limb and proceeded to peck away and eat part of an acorn. After watching for a minute I walked over, scaring her away, and climbed up into the tree itself to look at the spot. There was evidence of acorn-eating in several nooks and crannies (old acorn shells, acorn cups) but no stores. I walked around the area a little but saw no granary. The woodland here (and most likely the general AW situation) was quite similar to the next spot we stopped, however, so I'll defer a detailed description until then. Santa Barbara, 27m.W. Durango (35m E. El Salto), Durango, Mexico. elev. 7900 feet. [27 miles along the road from the Durango PEMEX] Here we finally hit the jackpot, when, after chasing a Scrub Jay for a bit, I turned upon an Acorn Woodpecker and followed him to a real, true-to-life, granary, complete with stores and all. I proceeded to search an area of land perhaps 1/4 mile by 1/8 mile, looking for other granaries or birds. Later in the day, on our way back from Durango, I did the same thing just a little further up the road. I also looked at the trees carefully and took some pictures
