A Dixon 1947 Journal June 22. Yellowstone River, 7 mi NE Glendive, 2000ft, Dawson Co, Mont. Cottonwoods. At the edge of a meadow, brush waist high chiefly Symphoricarpos extending ±100 feet toward dense stand of young willow. Many dead branches above bushes. I noted an Eastern Kingbird frightened from its perch on one such branch as I approached. When 25 yards past this point I heard a call & noted the Eastern Kingbird and a Western Kingbird perched on adjacent branches. I collected the latter (♀ no 46). Possibly nesting in nearby cottonwoods although mate or neither bird seen in area. I worked through an area of cottonwoods which grow more or less in rows parallel to the river. Undergrowth variable, either willow staves a waist high Symphoricarpos - Rosa. Red-eyed Vires singing in Cottonwoods. Noted a Sparrow Hawk at the edge of the meadow & gave perched in cottonwood. Lazuli Bunting or singing from higher perch in brush patch. Collected a ♀ Yellow Warbler (no 51) in dense stand of young willow. Missed shot at mate. At this time called up pair of HouseWrens, Chats, Redstarts as well as of Yellow Warbler. Found nest presumably of this Warbler as I collected within a few yards of it and ♀ remained in area. Nest cup-shaped similar to nests of this species seen previously - located in fork of willow 2" in diameter about
