Nor can the song of the ring-dove, or that of the mourning dove; the latter is so slight in sound that it would not be heard at all were it not so perfectly given. This song is often heard before a storm. There are other good weather prophets who warn us of coming storms. The robin sings a sad, sweet song before the rain. The cuckoo, the bob-white and others give us warning of approaching storms, as do certain owls.
The notes of alarm which the birds use are quite different from their songs. They are always given with a rising inflection and there is a harassed, pathetic quality to those notes. One day I stepped to my front door with a couple of small sparrow-hawks balanced on my finger. They were too small to fly and perfectly harmless, but what happened?
In less than a minute's time, there were at least fifty birds of probably a dozen different species, crying and quitting at the top of their voices, protesting in no uncertain language that I, the friend of birds, had dared bring these robbers and murderers to my front door.
