1978 Walter D. Koenig Melanerpes formicivorus El Batel, Sinaloa, Mexico, 570' elev. (21 January) that it is in this species of pine, that the woodpeckers build granaries. In fact, all the standing trees, including several (6+) snags examined, had a very different type of bark, often furroughed but never the "Yellow Pine" type so beloved by the dear Wickerbills. The closest we came to any storage holes at all was one cut section of a "Yellow Pine" which had 6 or so holes large enough to possibly have been storage & holes at one time. Given this state of affairs, it becomes more comprehensible why there only now appears to be 1 group of perhaps 4 (maybe 5) woodpeckers in this entire area - the granaries of all have (long?) since been cut down. Thus the remaining question may lie more pointedly on how this one remaining group survives. For one thing, it seems inferentially clear that part of their strategy seems to be to range over a very large area, at least during the winter, presumably in search of suitable foraging sites. This is suggested by ① our inability to locate them regularly in the same area ② the calls coming from across the canyon &/or far down the canyon, given our impression that there really can't be more than one group of birds living here ③ José's indication that one can find el Carpintero far down the
