Pitlka 1946 Oct. 13 El Batel, 70 km. NE Mazatlan, 5100 ft., Sinaloa and others undoubtedly peculiar to the Mexican mountains. Thru bog Rubus (blackberry), Rosa, and the madrone suggest Californian woodlands; the oaks are of kinds not occurring in California; large-leaved, more open, and taller trees; the pines are long-needled, the needles drooping gracefully. Poke-berry plants are common and suggest the deciduous forest margins. Mixed in are many strange species of undoubted southern affinity, as bush-composites, the epiphytic growths of bromeliads, orchids, lichens, and mosses, and several species of trees, including an acacia. None of us saw any sign of Cyanocorax dickeyi, though the type locality is in full view west of us from the hillside a short distance above camp. I met a young Mexican with whom I tried to converse, but was able to learn only that the "huaracas blanca y azul" occurred "arriba." Later Starker spoke to him and arranged to have him collect quail, Jays, and a few other species which we particularly want. In the late afternoon, the Mexican—Alberto Labrador- brought in two, and said he'd obtained them along the ridge above our camp. They are indeed spectacularly colored birds.
