Some Common Birds Useful to the Farmer (1926 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. This 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.
