R. K. Selander, 1954 33 May 9 Vicinity of Iguicar de Malamuros, Puebla Along stream near our tent I collected a pair of Thryothorus felix - in scrubby growth beneath Taxodium trees - They stayed well down in the bushes - the ♀ had a brood- patch. About 40 feet away I saw a Canyon Wren working out of a large crack in the face of a vertical rock cliff - the bird flew into the Taxodium tree adjovent to the cliff after I fired and missed. Saw a pair of Melanotis caeruleus along river valley as if they had a nest nearby. Also along the river are Sporophila torquata, and Contopus sp. Red-wing blackbirds common along road from camp to Malamoros. Barn swallows common & some cliff swallow also, Chordeiles acutipennis fairly common - fly at dusk. Also heard call of A. minor. We drove to an spot near Chinela and hunted in the morning for cootus wrens. Aimophila humalis common. Also Toxostoma curirostre, Chordeiles acutipennis. Skinned birds in afternoon then drove along highway, making several stops S of Malamoros for cootus wrens (no species accounts). No rain this evening. Hooded skells in afternoon - we are running out of ammunition so it will be necessary to buy a supply of .410 ammunition in Puebla and re-load these shells with dust shot. I gone home 50 16 gauge shell cases & 100 .38 cases in exchange for 3 Kilos of small shot which I could not buy in Puebla.
