Atee in a bulletin issued by the bureau
Of biological survey, United States de-
partment of agriculture. More than
sixty species of them occur In North
America. True to their name they
frequent the shores of all bodies Of
water. large and small. but many OF
them are equally at home on plains
and prairies.
Throughout the eastern United
States shorebirds are fast vanishing.
While formerly numerous species
swarmed along the Atlantic coast and
in the prairie regions, many of them
have been so reduced that extermina-
ton seems imminent The black-bel-
lied plover or beetlehead, which oc-
Cured along the Atlantic seaboard In
great numbers years ago, is now seen
only as q straggler. The golden plover.
once exceedingly abundant east Of the
great plains, is now rare. Vast hordes
of long-billed dowitchers formerly win
tered in louisiana; now they occur
only in infrequent -focks of half
dozen or less. The Eskimo curlew
within the last decade has probably
been exterminated and the other cur
LEWIS greatly reduced. In fact. all the
larger species of shorebirds have suf-
fered severely.
So adverse to shorebirds are present
conditions that the wonder Is that any
escape In both fall and spring they
are shot along the whole route Of their
migration, north and south. Their
habit of decoying readily and per-
sistently. coming back in flocks to the
decoys again and again. In spite OF
murderous volleys, greatly lessons
their chances of escape.
The breeding grounds Of some Of
the species In the United States and
Canada have become greatly restrict
ed by the extension Of agriculture. and
their winter ranges In South America
have probably been restricted in the
same way.
Unfortunately. shorebirds lay fewer
eggs than any Of the other species
generally termed game birds. They
deposit only three or four eggs. and
hatch only one brood yearly. Nor are
they in any wise immune from the
great mortality known to prevail
among the smaller birds. Their eggs
and young are constantly preyed upon
during the breeding season by crows.

than two young for each breeding pair.
It Is not surprising. therefore. that
birds of this family. with their limited
powers Of reproduction. melt away
under the relentless warfare waged
upon them. Until recent years shore
birds have had almost no protection.

The protection Of shorebirds need
not be based solely on esthetic or SEN
timental grounds, for few groups OF
birds more thoroughly deserve protec-
ton from IN economic standpoint.
Shorebirds perform an important serv-
