Zonotrichia leucophrys 10. July 26 6172 Chalot (College + Chalot) Oakland, Alameda Co. Calif. Jim Mulligan live-trapped 2 ad. ♀♂ which he brought to me. He said both had been singing. Both birds had enlarged testes, but were in early stages of the annual molt. The first (843) had almost all lower back feathers nearly full grown - many of these fell out with the remnants of sheaths on them. The other (844) was similarly molting on the back, and the primaries as well. The left wing had prim. 1+2 in sheath, 1 large, the rt. wing had 1+2 similar to left, + additionally the 3rd prim was just through the skin. Left P-3 was not yet dropped. No molt of secondaries or crown or breast on either bird.
