Most birds migrate at night; and a continued warm rain followed by a clear warm night is sure to bring a host of new arrivals. If you listen on moonlight nights, you can often hear their chirps and calls as they pass over. During foggy weather many meet with accidents by getting lost and being blown out to sea, or by flying against monuments, buildings, or lighthouses.

Mr. Chapman tells us that, when migrating, birds fly at a height of from one to three miles, and that our Eastern birds leave the United States by the way of the Florida peninsula. They are guided in their flight by the coast-line and the river valleys.

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.
