On June 5 and August 29 Magpies were noted commonly in Montana along the Oregon Short Line, nearly to Monida, Fremont County. I had expected to find them common in Fremont County, but not a single one was ob- served during the summer. I was told that they had been common in former years, and I found a number of old nests in willow thickets, near springs. but there were none of recent make. 51. Cyanocitta stelleri annectens. Black-headed Jay. Occurs sparingly in the heavily wooded canyons throughout the county. 52. Corvus brachyrhynchos hesperis. Western Crow. Not common.
