Journal 6 February 1979. MUZ Berkeley CALIF count at Beertop Canyon near upper Tamaras Canyon in Texas Ranch, (Gymnops) had seen & juvs. there californians in morning, 6:00 gto. from then on some observers camped. He had good colorpints of the juvs, then w. (4 ASA 400 Kodachrome film) 500 mm lens or Nikon 35 mm camera (could be used to identify indivs. by ordering pattern & shot R primary (+/- 0?) on one). He collected fresh experiment at carcass (freshly small part eaten); analysis showed very high levels estrogen, higher than any test in god bird. Fry hypothesis that DDT has estrogenic affects & high doses might cause a bird to retain immature plumage beyond usual period of years. No empirical data for other cultures yet, however. Argued w. Fry against capture & possibly made some progress. 9 February 1979. Friday. Departed Berkeley about 5:00 and drove via To San Luis Obispo C., CALIF. hwy 5 to Cholame & Cl-McMillan ranch.
