Doves resemble Wild Pigeons, but are much smaller, and their rapid flight is accompanied by the whistling sound of wings, while the flight of the Wild Pigeon is said to be noiseless.

During the nesting season they may be found in pairs, generally in open woodlands or tree-bordered fields. They also visit roads and lanes to dust themselves. The sweet, sad call of the male has won for this species its common name; it consists of several soft was, which may be written : Coo—o-o, all-CI)o—0-0-—coo-0~0— corHJ—o. Under favor- able circumstances these notes may be heard at. a distance of at least two hundred and fifty yards: they are littered slowly and tenderly, and with such apparent depth of feeling that one might. easily imagine the bird was mourning the loss of his mate, instead of singing a love- song to her.

At this season one or both birds maybe seen performing a peculiar aerial evolution. Ascending to a height of about thirty feet. they fly for some distance in an unnatural manner. and then, after a short sail. return to their perch. When engaged in this performance they very closely resemble : Sharp-shimied lIawk.

After the nesting season Doves gather in flocks of varying size and frequent grain and corn fields. During the day they visit the near- est supply of fine gravel. which they eat in large quantities as an aid to digestion. In some lo 'alities. soon after sunset, they regularly re- pair in numbers to some favorite place to drink, and then retire to their roosts.
