Passerina amoena June 18. Yellowstone River, 7 mi. NE Ellendive, 2000 ft., Dawson Co., Montana. Completely overcast, raining steadily, with intermittent breaks. I noted a ♂ singing singing from top of a boxelder in a clearing at one end of the woods (boxelder + elm) west of camp. Clearing was roughly 150 feet square with several isolated trees; undergrowth was almost entirely Symphoricarpe 2-2½ feet high with some Rosa and Ribes also. I was unable to collect this individual but later shot one (perhaps same bird). At 11:30 I noted 2 ♂♀ present at the south end of the clearing near a brush pile. A ♀ was perched on the brush pile and one ♂ dropped down beside the ♀, pausing momentarily and flying upward to perch. I was unable to see what happened then but shot the ♀ after the ♂ flew up. I couldn't locate ♀ & both ♂♂ left area. Another ♂ was singing at the edge of the woods adjacent to the meadow. He shifted his song perch frequently, keeping to trees within a few yards from the edge of the woods. The ♀ appeared once in rose thicket between the woods and meadow. June 21. Yellowstone River, 7 mi. NE Ellendive, 2000 ft., Dawson Co., Montana. I collected a ♀ (204) today, one of a pair called up by hissing. As also noted yesterday, the ♂ was more conspic- uous than the ♀; in the former case I was unable to get a shot at the ♀.
