it was unusual to note more than two or three daily and
almost none remained after November 1 [November 1, 1916].

Crow migration.

  Flocks of Crows, bred or breeding further to the north
and migrating southward over or past our farm, were noted
there on October 13 [October 13, 1916] 40+ [in a flock], 14 [October 14, 1916] 9 [in a flock], 26 [October 26, 1916] (large flock), 27 [October 27, 1916] 37 [in a flock] counted, 115 [in a flock] [counted], 28 [October 28, 1916] 37 [in a flock] c. [counted],
November 3 [November 3, 1916] 198 [in a flock] roughly counted, 4 [November 4, 1916] 50+ [in a flock], 11 [November 11, 1916] 40+ [in a flock]. Almost all these
flights occurred between 7 and 10 A.M. The birds composing
them immediately pursued a south-westerly or perhaps even
