had eaten 77.7 per cent of animal food and 22.3 per cent of vegetable matter. Fifty per cent of the animal matter consisted of bloodworms, 25 per cent of Planorbis snails, and 5 per cent of _Corixa reticulata_. The vegetable matter consisted entirely of seeds, of which those of Compositae formed 33.3 per cent, _Sesban emerus_ 30 per cent, and _Persicaria portoricensis_ 36.7 per cent. In addition to food, the stomachs contained mineral matter (coarse red sand) forming 32.5 per cent of the stomach contents. _Behavior._--Lucien M. Turner, who has had abundant opportunity to observe this species in Ungava, writes in his notes: The flight of these birds is remarkably firm and swift, generally in an undulatory manner and swerving to the right or left often with the body inclined to one side, the wing nearly perpendicular, alternately presenting the upper and lower surface of the body. Just before alighting the wings are raised until the tips nearly touch over the back and for a moment held outstretched and then slowly folded. The bird is quite active while searching for food and seldom remains more than a few seconds in a spot, where it constantly picks here and there for the minute organisms which form its food. During this time all is activity and quite in contrast to the interval while the tide is high and the bird is on the high land resting and digesting its food. Here it is more sleepy and less easily disturbed. The eyesight of these sandpipers is certainly very acute, as they are able to detect the presence of a person at a long distance and give a twittering, snipey note, otherwise regardless of approaching danger. In all their doings the utmost harmony seems to prevail. The only object of their lives seems to be to gather food. No sooner does the water begin to ebb than a few of these birds will swish over some point of land with merry twittering, eagerly scanning the bank for the least appearance of mud now being exposed. By the time the tide has half ebbed myriads of these birds are sweeping back and forth along the river. As the water shallows over well known bars, and scarcely has the water shoaled enough to permit the birds to alight without swimming, than as many sandpipers as can collect on the place eagerly alight and begin probing the ooze for food. The lowering water is followed by the thronging birds to the last inch.
