Cogswell 1949 Vermivora celata Dec. 4 - Gray Lodge Refuge, S.W. Butte Co., Calif. In the twigery at the base of a 20 ft. willow tree along Butte Creek here. I heard the characteristic sharp "chip" mote of this species. Squeabing brought it up for a close view by me and by Ken Schulz, who was with us. The bird was only moderately yellow below, with definite but fuzzy dusky olive streaks on the breast; throat + chest more nearly pure yellow. Another (?) bird was heard almost immediately afterward at some distance in the riparian woodland, which here is perhaps 100 ft. deep, with trees not quite giving a closed canopy. [ I note only 1 good "winter" record for the species in Pac. C. Avifauna 27 ]
