R.E.Johnson 1966 Journal West Fork Yaak River, 5000 ft, Lincoln Co., Montana (unt.) July 9 Ames, Moore, & I drove down to Pete Creek and collected at about 4000 ft. They moved up slope and saw Black-headed Grosbeaks & Orange-crowned Warblers. I stayed along the stream bottom which is filled with a tall mixed forest of Western Red Cedar, Douglas Fir, Grand Fir, Engleman Spruce, Western Hemlock, Western White Pine. Understory included alder, thimbleberry, gooseberry, Fairy bells, & Ferns. I collected 3 adult Yellow-bellied Sapsuckers feeding young in a streamside snag. The hole was 40 ft. up & was West facing. Two of the adults were females and one was a male. Two Empidonax flycatchers were collected from the tops of streamside conifers. They moved back & forth between tree tops, usually remaining over 50 ft above the ground (or water). Each gave the typical Hammond "slurp" note periodically. Russell prepared one & I, the other. They behaved similarly to those I collected at Spar Lake (prepared by Russell). A ♀ Rufous Hummingbird dove at me in a small streamside clearing. Russell prepared the specimen. I also collected a Mountain Chickadee, a Golden-crowned Kinglet, two Red-breasted Nuthatches and 2 Frogs in this habitat. After 9 P.M., Dave Conard spotted a bat over the road near camp and we all went out after bats, the first we had seen. Two high flying Silver-haired Bats & one low flying Brown Bat were shot. We're not sure who
