Some Common Birds in Their Relation to Agriculture
Beal, F. E. L. (Foster Ellenborough Lascelles)
Birds -- United States
Although the cherry bird is not a great insect destroyer, it does some
good work in this way, since it probably rears its young mostly upon
insect food. On the other hand, it does not devour nearly as much
cultivated fruit as has been asserted, and most, if not all, of the
damage can be prevented. The bird should therefore be considered a useful
species, and as such should be accorded all possible protection.
THE CATBIRD.
(_Galeoscoptes carolinensis._)
The catbird (fig. 18), like the thrasher, is a lover of swamps, and
delights to make its home in a tangle of wild grapevines, greenbriars,
and shrubs, where it is safe from attack and can find its favorite food
in abundance. It is found throughout the United States west to the Rocky
Mountains; occurs also in Washington, Idaho, and Utah, and extends
northward into British America. It winters in the Southern States, Cuba,
Mexico, and Central America.

The catbird always attracts attention, and the intruder upon its haunts
soon understands that he is not welcome. There is no mistaking the meaning
of the sneering voice with which he is saluted, and there is little doubt
that this gave rise to the popular prejudice against the bird; but the
feeling has been increased by the fact that the species is sometimes a
serious annoyance to fruit growers. All such reports, however, seem to
come from the prairie country of the West. In New England, according
to the writer's experience the catbird is seldom seen about gardens
or orchards; the reason may possibly be found in the fact that on the
prairies fruit-bearing shrubs which afford so large a part of this bird's
food are conspicuously absent. With the settlement of this region comes an
extensive planting of orchards, vineyards, and small fruit gardens, which
furnish shelter and nesting sites for the catbird, as well as for other
species, with a consequent large increase in their numbers, but without
providing the native fruits upon which they have been accustomed to feed.
Under these circumstances, what is more natural than for the birds to
turn to cultivated fruits for their supplies? The remedy is obvious;
cultivated fruits can be protected by the simple expedient of planting
wild species or others which are preferred by the birds. Some experiments
with catbirds in captivity showed that the Russian mulberry was preferred
to any cultivated fruit that could be offered.
