Some Common Birds Useful to the Farmer (1915 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.

[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.
