Pitchea 1943 Dendroica nigrescens June 16-18 Zuni E Hayfork, 2400 ft., Trinity Co., Calif. Occurs in mixed pine-oak woodland of moderate height. It appears to prefer a predominance of deciduous trees together with scattered underbrush (Ceanothus and manzanita). Most abundant dry, woodland-covered on low ridges west of Big Creek. June 18 On one of the low ridges west of Big Creek, mentioned above, I stood in one spot and heard five different males singing from various, separate parts of the woodland about me. Earlier, I had observed several adults feeding young out of the nest, and it occurred to me that the continued singing of the males might mean that these birds were preparing for a second brood. I took one female feeding well-grown fledgling (#535). Her ovary showed three enlarged yolky ova, one 4mm in diameter and two 7mm in diameter. This appears to confirm the probability of two-broodedness in this species at least in this region.
