LLW01F 1964 Journal August 17 16 1/2 mi. SW Matatlan to Tehuantepec, Oaxaca, Mexico Up at 0520. After breakfast I went out to record Bridled Sparrows while Duke collected. Bridled Sparrows do very little chattering in dust, but the ♀ spends a fair amount of time singing from elevated - usually dead - perches. & sometimes comes up into nearby shrub & calls also. Packed up car & drove south in completely overcast weather to 6 1/2 mi. SW. Totolapan where stopped to collect Bridled Sparrows. Area is Acacia + Cardaba castio- dominated hillsides. In places the canopy is nearly closed. It is very dry & there is little herb layer on the rocky hillsides. Found 3 family groups with on young each. Young stub-tailed, '2 tail, & full grown. One ♀ had no feathers left body good patch & was undergoing postnuptial molt, but the other was emerging for a 2nd breeding attempt. Also got ♀ w/ recently ruptured follicles. Drove on along Pan Am Hwy & stopped by Oridge to skin. Were soon forced by rain to leave. Ran into intermittent rain for then until dropped onto coastal plain NE of Tehuantepec. Arrived at Tehuantepec at 1730 + took room at Hotel Tehuantepec. Finished Skinning birds including a Roadside Hawk Dick shot enroute at 2030. Then to supper & wrote notes. Finally to bed at 2200 in hot, humid weather.
