L. Umbagog. 1890. Perisoreus canadensis. copy I set Will Sargent to following our Jays to-day while my cook Oct.25, put out a lot of large pieces of biscuit for them. Sargent traced them about a half a mile to a dense white spruce swamp. Here he found two of their store houses. One in the top of a pine stub where a piece of wood was started off at an angle 17 contained about a pint of biscuit & brown bread. The other in a larch stub in three peck holes of either Colaptes or Hylotomus, the three holes all crammed full of bread packed tightly, in all nearly a quart. He saw the Jays carry the bread to both stores and they saw that he saw them. In fact they caught him in the act of climbing the trees. This about noon. He went back to the stubs & found them in the act of removing the last pieces of bread from both. After they had finished this task they came to camp again & worked till dark. He says they alighted regularly on the tops of the tallest trees to reconnoitre before visiting their hoards in the swamp. Will Sargent again followed our Canada Jays this afternoon, and found two more of their store houses, each containing a pint Oct.26, or more of biscuit, beans etc. One was in the angle at the point where a leaning stub touched another, the other within a large scale of semi-detached berk on a dead hemlock. He watched both places for sometime. Each seemed to be visited by one bird only. The one that used the scale of bark as a store house, packed each piece of bread with some care first fitting it in place and then tamping it in solidly with its bill, the other merely dropped its loads into the crevice. 29
