LL Wolf 1964 Journal August 6 Cuernavaca, Morelos, Mexico Up at 0530. After breakfast drove north on R. 95- like toward Mexico City. Stopped at km 60 in cut-over pine-oak woodland. Looked for Rusty Sparrows with no luck. The shrub layer is nearly continuous (may be too dense for Rustys). Possibly excluded by Pipilo erythrophthalmus +1 or Atlapetes - the Pipilo is extremely abundant. Left at 0830+ drove back toward Cuernavaca to km 64 when we camped last year. This area is 700+ ft. lower & much more open. Found at least three singing Rusty Sparrows, but unable to follow any for any time. Drove back to km 60 at 1030. Watched mixed flock of birds moving thru oaks + Arbutus sp. Composed of Black-created Brushfinch as nucleus, with Mexican Chickadees, Olive + Red Warblers, Hairy Woodpecker, + two woodcamps. Also seemed to be some flycatchers - Mitrephanes phaeocercus + Contopus pertinax associated. Moved on uphill + found another flock- moving thru low oaks + shrubs. - Again Coelopterus melanoctis was the major species by number. Also Bell's Warbler, Hairy Woodpecker, Brown-throated Hawk (2), Olive Warbler (2), Red Warbler (3+), Rufous-sided Towhee (2), + Hutton Vireo (2). Dick returned to car at 1420 + we drove back to Cuernavaca where spent rest of day preparing specimens. The pine-oak forest at km 60 has been cut more since last August + there were piles of freshly cut wood + the sounds of more cutting during the morning. In places the shrub layer is dense providing habitat for Pipilo, 2 species of Atlapetes (galeatus + virenticeps) + Toxicostoma ocellatum. But it won't be too long before the larger pines + oaks are gone.
