****:DOVES AND PIGEONS
There are several hundred kinds of doves and pigeons distributed
around the earth, including approximately 150 varieties of domestic pigeons.
They vary from the giant crowned pigeon
of New Guinea to the little Eastern Ground Dove which is about the size
of a bluebird and native to our South Atlantic
and Gulf coasts. The terms "dove" and "pigeon" are used interchangeably
in the common names given them. They have
two peculiarities. One is that, in drinking, they do not sip and raise
their heads as other birds do, but take long draughts.
The other is that their naked helpless young are fed with a secretion,
known as "pigeon milk", from the parents' crops;
later with regurgitated half-digested food. A naturalist, attempting to
raise a young dove by hand, was unable to get it to
eat until he discovered and pressed a little swelling at each corner of
its mouth. Then the mouth flew open and the
throat muscles began to work spasmodically. Apparently, when the old bird
and the young bird interlock bills, these
swellings are pressed and the squab is enabled to swallow. The dove has
become an emblem of peace and love,
probably because of the devotion of a mated pair to each other and to their
young, the familiar strutting, billing and
cooing of the male during courtship, and their gentle timid nature. Doves
and pigeons have been used as messengers
and food since earliest time. In the Bible we are told that Noah sent forth
a dove and, when she returned with an olive
leaf in her mouth, he knew that the water had receded from the earth. The
early Hebrews were commanded to offer
turtle doves and young pigeons as sacrifices in atonement for sin. In 3000
BC the Egyptians were raising them for food.
They were employed by the early Greeks and Romans, and in the first Crusade,
to carry messages -- just as carrier or
"homing" pigeons were used in our two world wars. All of our domestic pigeons
have been developed, by selective
breeding, from the Blue Rock Pigeon -- the Rock Dove which nests in rocky
cliffs along the coasts of Europe. Millions
of domestic pigeons are virtually wild. In many cities they have become
a nuisance but efforts to eliminate them, by city
and park administrations, are defeated by the public which persists in
feeding them. In suburban and rural districts,
flocks commonly fly to and fro in close formation, apparently just for
the fun of it, wheeling in unison like soldiers at
drill. In a previous bulletin we told of the slaughter and extinction of
the Passenger Pigeon which formerly inhabited the
forested regions of this country in billions. Today, except for the Band-tailed
Pigeon of Canada and western U. S., the
Ground Dove, and a few kinds found only in southern Florida or southern
Texas, the only native pigeon is the Mourning
Dove or Turtle Dove. It is a slim brownish bird, smaller than most domestic
pigeons, with long pointed tail and wings,
conspicuous white tips on the tail feathers, and a small black spot behind
the eye. A bird of the open country, it is
valuable because, in addition to waste grain and insects, it feeds chiefly
on weed seeds. Two glossy white eggs are laid
in a nest which is merely a crude thin platform of sticks, usually in a
small tree or tall bush. The turtle dove is one of our
early spring arrivals, and then we hear the low mournful mating call of
the male: "Ooah-cooo-cooo-coo". A few remain
during winter. They rise swiftly from the ground with a twittering whistle
of wings and are swift fliers that travel long
distances to drink and bathe. Migrating in flocks in autumn, they are now
in danger of extermination by excessive
hunting. "The flowers appear on the earth; the time of the singing of birds
is come, and the voice of the turtle is heard in
our land." Turtle? Solomon was not that dumb.
