LL Wolf 1964 Journal July 14 Cuernavaca, Morelos, Mexico Up at 0500 (light rain at night - heavy in late afternoon yesterday). Had breakfast + drove out to Cañon de Lobos which is on road to Cuautla. Vegetation wet from rain. I walked up S side of canyon while Birch collected along stream in bottom of canyon. I spent morning looking for Simulitis ruficauda + A. humeralis. Worked mostly on dry hillsides at east end of canyon. Walked up N side very far to South with no luck. Found nest of A. ruficauda with four eggs + nest Gerygoneulus jocosis of Tropythorus plumbeus with 3 eggs. Spent rest of morning watching several groups of A. humeralis. Was stopped by game warden just as returning to car. Had left permits in car so he would check on list to see if we were legal. Back to apartment where spent rest of day to 2030 skinning birds.
