KDixon 1947 Journal 55. June 19. Yellowstone River, 7 mi NE Glencoe, 2000 ft, Dawson Co, Mont. I proceeded along east bank of stream to some willows beyond the meadow. Willows were slender trees 12-15 feet high forming a very dense stand. The only birds present were Redstarts, several of which I called up by hissing. I proceeded inward away from the stream into a floodplain growth of the same willow (more widely spaced) and a tangle of Rosa, Ribes, and tangled dead limbs and branches many of them prostrate, with tall Cottonwoods above. Here I noted a pair of Yellow Warblers & collected the singing 07. This species, like the Redstart is attracted by hissing. I also called up an Ovenbird, which hopped up on the ground, but failed to collect it. I collected a ? Black & White Warbler which was singing in a dead tree. Its song was preceded by a call note 'trip'; the song was dry and did not carry far 'kee-sa'-'see'. When skinned, this bird (no 30) had white cysts about 1/8" long in muscles of legs, back and facial area. In this habitat, I also noted Redstarts, Red-eyed Vireo, Chat, but no Yellowthroats. In thicket of Prunus, I collected a Spotted Towhee (no 34) singing from perch to which it dropped from higher on the shrub after hissed. Noted a Robin flying past camp in late afternoon and a Nighthawk flying a yard or so above grass at dusk. Cloudy and windy in evening. Nocte head.
