1978 Walter D Koenig Melanerpes formicivorus El Batel Durango Hwy, Sinaloa Mexico elev. 5700' (20 January) We walked around various trails here until nearly 1600, seeing quite a few interesting birds but no sign (!) of acorn woodpeckers, anywhere (not even any calls elsewhere!). We were greeted upon our return, unfortunately, with a smashed rear window and the looting of Paris suitcase and a lantern. The vegetation here was cursurally (?) described previously. Some increased detail on the 2 pales is available on the back of these sheets. There is also, as it happens, a rather rarer 3rd species of oak, I think, one with extensive white powder on the underside of the leaves. I have no further information on it, however. 21 January Today we were led around the area by José Angel, who we met yesterday while trying to do something about our smashed window. He knows the Acorn Woodpecker (el Carpintero) well, and we eventually- were able (with some difficulty, as our Spanish is not even rudimentary) to convey our desire to see trees with stored acorns in them. He proceeded to take us up around the hills above Batel, taking us especially to at least one spot, where there were several beautiful oaks in a clearing, claiming (not unreasonably) that there were Woodpeckers here, but that there storage tree (looked for in vain) has been cut down 2 months before by loggers.
