February Twenty-fourth
Some migrants fly in compact flocks of hundreds, like the ducks, for example, while others, like the swallows, spread out. Then, again, there are birds that arrive in pairs or singly. With still others, the male precedes his mate by a week or ten days. Not infrequently a flock of birds containing several different species will be seen. This is particularly true of the blackbirds and grackles.
