Some Common Birds Useful to the Farmer (1926 edition)
Beal, F. E. L. (Foster Ellenborough Lascelles)
Birds -- United States
In summing up from an economic point of view the character of the food of
the California jay, it must be conceded that it is not all that could be
wished. Its taste for birds' eggs and fruit is entirely too pronounced,
and at present the species is superabundant in California. While the
natural food supply of the bird has been lessened by bringing the woods
and brushy canyons under cultivation, the same areas have been planted to
fruit, and naturally the jay takes the fruit as an acceptable substitute.
A considerable reduction of the bird's numbers would appear to be the
only effective remedy.
THE PHŒBES.
Among the early spring arrivals to their northern homes none is more
welcome than the phœbe (fig. 18). The common phœbe[48] breeds
throughout the United States east of the Great Plains, and winters from
the South Atlantic and Gulf States southward. Its western relative, the
black phœbe,[49] is found from Texas west to the Pacific coast, which
it occupies as far north as Washington, replacing through most of this
region the common or eastern form.
[48] _Sayornis phœbe_.
[49] _Sayornis Nigricans_.
Though naturally building its nest under an overhanging cliff of rock
or earth, or in the mouth of a cave, the preference of the eastern
species for the vicinity of farm buildings is so marked that in the more
thickly settled parts of the country the bird is seldom seen at any
great distance from a farmhouse, except where a bridge spanning a stream
affords a secure spot for a nest. Its confiding disposition renders it a
great favorite, and consequently it is seldom disturbed.
The phœbe subsists almost exclusively upon insects, most of which are
caught upon the wing. An examination of 370 stomachs showed that over 89
per cent of the year's food consists of insects and spiders, while wild
fruit constitutes the remainder. The insects belong chiefly to noxious
species, and include many click beetles. May beetles, and weevils.
Other beetles, belonging to 21 families that were identified, make up
10.65 per cent. They appear to be eaten very regularly in every month,
but the most are taken in spring and early summer. May is the month of
maximum consumption, with 20.43 per cent. Beetles altogether amount to
15.3 per cent, which places them second in rank of the items of animal
food. The notorious cotton-boll weevil was found in six stomachs taken
in the cotton fields of Texas and Louisiana, and five individuals of the
strawberry weevil were taken from one collected in Texas. Many other
beetles contained In the stomachs are equally harmful, but are not so
widely known. Such are the corn leaf-beetle, which feeds upon corn; the
12-spotted cucumber beetle, and the striped cucumber beetle, both of
which seriously injure and sometimes destroy cucumber and squash vines;
and the locust leaf miner, which is sometimes so numerous that all the
locust trees over large areas are blasted as by fire.
