Cyanocitta cristata. Lake Umbagog, Maine. 1895. At about eight o'clock this morning I was standing on the Sept. 20. hemlock knoll watching some small birds when I heard directly overhead a sound as of a gust of wind blowing through pine woods. As there was no wind at the time I concluded that an Eagle or Blue Heron had swooped down through the trees. But an hour later the mystery was explained when happening to see a dozen Blue Jays rise above the trees I watched them closely Closing in together like so many Blackbirds they ascended in a compact flock by a spiral course to a height of several hun= dred feet and then half closing their wings dashed down a steep incline like so many Falcons at the same time making the loud rushing sound I had heard earlier in the morning. I think that ln both occasions they were intending to start on migration but made "false starts" changing their minds for some reason or other. Cyanocitta cristata. Lake Umbagog, Maine. Migrating. 1897. Early in the afternoon witnessed a migration of Blue Jays. Sept. 22. They came from the woods on the north side of the meadow (Cur- tis Meadow) and rising to a height of from 100 to 300 feet passed out of sight over a wooded ridge to the south. There was one flock of forty-three, another of ten; the others were scattered birds or parties of three to five or six. Some of them turned back and plunged down headlong into the woods from a considerable height as I have seen them do at Pine Point.
