We spent the greater part of one day in following them
in order to ascertain what they did with the great quantity
of food which they carried off. We supposed that we should
find them hoarding it somewhere in a hollow tree or similar
place; but this proved not to be the case. On the contrary,
they took it various distances and to various places, rarely
or never, so far as we could ascertain, depositing two loads
in the same place. They would place a mouthful of oat meal
perhaps on the horizontal branch of a large hemlock, three or
four crumbs of bread on the crotch of a dead stub, a large
piece of bread on the imbricated twigs of living fir. On one
occasion we saw one deposit four beans carefully on the top
of an old squirrel's nest high up in an arbor vitae tree. My
men climbed to a number of places where the birds were seen
leaving their load in order to make sure that they really did
this. Sometimes they went only two or three hundred yards
back into the woods behind the camp; at others we followed
them for upwards of a mile. They were very sly about making
their deposits, and, if they saw us watching , would either
drop their loads or fly on until out of sight. They had, how-
ever, two regular roads which they followed, and their depos-
its were made along the line of one or the other of these.
On these roads they had regular resting-places in which they
alighted for an instant before pushing on. These resting-
places were ordinarily about one hundred yards apart, While
at work they were very sly as a rule, rarely uttering more
than a low, scolding note, but if displeased or disappointed,
as, for instance, when the food was covered by a blanket,
they would fly up into the trees above the camp and scream
in shrill and apparently angry tones for several seconds at
a time.
After these Jays had been working steadily for about a
week, a third appeared. He was evidently a stranger and was
regarded with dislike and suspicion by the other two who ne-
glected no opportunity to bully him to the utmost. As a
rule, he submitted to this treatment very mildly, waiting
until the other birds were gone, and then taking his turn.
Rather curiously he followed the same route however as the
others, and apparently deposited his loads in very much
the same places.
