R.K. Selander, 1952 40 August 20 Cuernavaca, Morelos to Pie de la Cuesta, 30ft, Guerrero, Mexico. two hour stop near Mexcala, Guerrero in desert area (Arid /Other Tropical zone?) to collect meloids. Got 4 or 5 species in one place. Searched for [illegible] cactus wrens (C. jocosus) for short while. Heard (C. jocosus ?) or C. humilis one! but unable to locate. [Saw a 7 also mexicana near Sacasoyuca, Guerrero]. Near Mexcala noted a white-winged dove and several parakeets (sp.?). Birds very rare here. Noted a flock of sparrows in mesquite bushes - like a zonotrichia, but light brown dorsally then Z. leucophrys and black & white head markings much more bold and distinct. = Aimophila agammata (=ruficauda) Notes rather wren-like. Saw many S.inea. Made a short stop 8 mi. S Mexcala, 3000 ft, Guerrero where I hunted about 20 minute for wrens. (There are 7 June skins of C. humilis in the Moore Collection from 7 mi. S Mexcala.) Saw no wrens - Took photographs of the area. Noted here white-winged dove, [Columbina aurifrons, and parakeets (sp.?)] -- Continued along highway, noting ravens (sp) at Zumpango. Stopped at Chilpancingo and located Wilmet W. Brown at the Hotel Mexico. Talked with him for two hours. He said cactus wrens are uncommon around Chilpancingo, but "abundant" at Pie de la Cuesta". He has a collection of ~ 2000 skins of Guerrero birds which he is trying to sell.
