_Spring._--The spring migration of this sandpiper is not extensive. Many birds have remained all winter on or near their breeding grounds in the Aleutian Islands; others have wintered along the coast as far south as Washington. D. E. Brown tells me that they remain on Destruction Island until May 1 and that they have been seen on Forrester Island as late as June 15. H. S. Swarth (1911) found them "very abundant" on Kuiu Island during his stay there from April 25 to May 6; he writes: In company with the black turnstone and some other waders, they frequented the broad mud flats, which, at low tide, extend over hundreds of acres at this point. As the tide advanced their feeding grounds became more and more restricted, until, as the last available spot was covered, the whole flock departed, with roar of wings, to some jutting rocks at the mouth of the bay, there to remain, preening their plumage and resting, until the receding waters again exposed the mud banks. The flocks seen at this place comprised many hundred individuals, and it is curious that the species was observed absolutely nowhere else. Herbert W. Brandt says in his notes from Hooper Bay: The Aleutian sandpiper is a common transient visitor in the vicinity of Point Dall and is said by the natives to be a breeding bird in the mountain fastnesses of Cape Romanzoff. This species was first identified by us on May 18, but it may have arrived a few days earlier because up to that time we did not suspect its presence. It associated itself with the red-backed sandpiper, to which in the field it has a marked superficial resemblance and in consequence we may have overlooked it. These birds at that time travelled in bands of from 20 to 40 individuals and at low tide fed on the ice-bound sea beach that was then exposed, but when the high water came in and up to the wall of shore ice, thus covering their feeding grounds, they moved back along the open river margins and marshy pond borders. From May 23 to May 28 they were very common, when suddenly they departed, only to reappear in early July. The natives are very positive in their assertions that this island dweller breeds in the rugged mountains about Cape Romanzoff, but as we did not visit that area we could not authenticate their statements, nor did we learn anything of its nidification.
