Some Common Birds Useful to the Farmer (1915 edition)
Beal, F. E. L. (Foster Ellenborough Lascelles)
Birds -- United States
The Steller jay[46] much resembles the eastern bird, but it is more shy
and retiring and seldom visits the orchard or vicinity of the ranch
buildings. Stomach examination shows that its food does not radically
differ from that of the eastern blue jay. As is the case with that
bird, a very considerable part of the food consists of mast, together
with a little fruit and some insects. The insects are largely wasps,
with some beetles and grasshoppers. The jay also eats some grain,
which is probably waste or volunteer. No complaints, so far as known,
are made against this bird. Until it shall become less wary it is not
likely to trespass to a serious extent upon the farmer’s preserve.
[46] _Cyanocitta stelleri._
The California jay,[47] although of a different genus, more nearly
resembles its eastern relative in food habits and actions. It freely
visits the stockyards near ranch buildings, and orchards and gardens.
As a fruit stealer it is notorious. One instance is recorded where
seven jays were shot from a prune tree, one after the other, the dead
bodies being left under the tree until all were killed. So eager were
the birds to get the fruit that the report of the gun and the sight
of their dead did not deter them from coming to the tree. In orchards
in canyons or on hillsides adjacent to chaparral or other cover great
mischief is done by this bird. In one such case an orchard was under
observation at a time when the prune crop was ripening, and jays in a
continuous stream were seen to come down a small ravine to the orchard,
prey upon the fruit, and return.
[47] _Aphelocoma californica._
Fruit stealing, however, is only one of the sins of the California jay.
That it robs hens’ nests is universal testimony. A case is reported
of a hen having a nest under a clump of bushes; every day a jay came
to a tree a few rods away, and when it heard the cackle of the hen
announcing a new egg it flew at once to the nest. At the same time the
mistress of the house hastened to the spot to secure the prize, but in
most cases the jay won the race. This is only one of many similar cases
recounted. The jays have learned just what the cackle of the hen means.
Another case more serious is that related by a man engaged in raising
white leghorn fowls on a ranch several miles up a canyon. He stated
that when the chicks were very young the jays attacked and killed them
by a few blows of the beak and then pecked open the skull and ate out
the brains. In spite of all efforts to protect the chicks and kill the
jays the losses in this way were serious.
