Howell, T.R. 1948 8 mi. N. and 13 mi W. of Canby, 4700 ft., Modoc Co., Calif. May 21 (cont'd) - I had now made a semi-circle and was back at camp; I turned west and walked along the edge of the Hackamore Reservoir. The vegetation on this shore is sagebrush and very small pine trees. Juncos, Chipping Sparrows, Audubon Warblers, Black-throated Gray Warblers. Empidonax ©, and Green- tailed Towhees were abundant; Black Terns were in good numbers over the water, a few California Gulls passed over, two Canada Geese were visible from the shore, and several Barn Swallows fed low over the water. Robins were in small numbers in the pines. I encountered a flock of warblers moving along the shore in the manner of migrants; most were Audubon and Black-throated Grays, but there were a few Townsends and Pileoloteds. The Townsend Warbler I collected was slightly fat. A Pygmy Nuthatch called loudly from a large dead stub. I watched him investigate an old woodpecker hole and then collected him. Several Mountain Chickadees passed through the trees calling but not singing. I turned southward again and walked to the same area mentioned in yesterday's notes which is somewhat cleared but with numerous large dead trees. Flickers were about and calling; I located a White-headed Wood- pecker (a ♀) and collected it; no others of this species were seen today. Fox Sparrows
