Selanden, 1954 65 Temascaltepec, 5500 ft. June 3 Real de Arriba and Temascaltepec is similar, but above Real de Arriba it is more humid and there are good stands of oaks with some epiphytes on them. Actually except for the riparian vegetation and several of the gulies sloping from the canyon sides - it is rather dry here. There is a good carpet of grass on the flat near the river and a good cover of herbaceous elements. The life-zone here is either upper or lower Sonoran - probably at lower edge of Upper Sonoran. (Photos 5,67 - Roll 28 are of camp 1 mi. E Temascaltepec.) I hunted for 4 hours from camp along slope of canyon up to Real de Arriba and then back to camp along the stream. In a thick stand of oaks & broad leafed trees on the slope I saw Atlapetes curriculi - rucha, blue mockingbird (very common), Turdus assimilis, Melozone kieneri, and up on top of the canyon wall I shot a Canyon Wren. In a stand of dry pines I took a Bewick's Wren and saw billed falconry; Aemophila supercans is fairly common in the canyon as is Catharus. Collected huge series of melecids of two types on herbaceous vegetation near our camp. The melecids were flying - almost in a swarm - and seemed to be heading toward one particular pair of herbs - but we saw them on other vegetation also. (Several photos of melecids perching leaves and #12 of the roll showing the Volcan from the summit.)
