Davis. 1940. Sparks Lake, Deschutes Co., Oregon. July 12. of very close approach before flushing. This P.M. Silly collected a Lincoln sparrow. I collected and skeletonized an immature ♂ Herizoreus. July 13. A.M. collected in willows at north end of Sparks Lake. Birds noted were: Spotted sandpiper, young; ring-billed gull, American batten, Brewer and redwing blackbirds, Intescient warbler, song lnioli, and Savannah sparrows, olive-sided and Traill flycatchers, violet-green swallow, killdeer. Most of the other birds previously noted about camp were also seen. Collected Rana on lake shore, along margins of creeks flowing into lakes. They are not found in the creeks proper, which have a hard gravel bottom affording no shelter, but rather in small blind outpocketings of the creek, which contain sluggish, warmer water. The bottom of these outpocketings is of two types: a) deep silt, easily penetrated by the frogs as they jump in; or b) dense alga, also affording protection. I flushed a littern from the edge of one of these places, where it was evidently hunting frogs. It flew about 70 yds. to a branch 30' up in a live lodgepole pine, & then, when I approached within about 20' of the tree, flew out over the meadows surrounding the lake, & lit some 200 yds. away. Collected a Rana in the grass at edge of Satan Creek where it flows past our camp. Also a Channophis in a hard flat in the willows at north end of Sparks Lake. Evidently feeds on the very young Rana which are plenti- ful in the grass between the clumps of Salix. Dr. P.M.
