T. Code 1958 Calcarius picta 3 August Okfilek Lake - two or three were seen around camp in the early morning. Later in the clay tree were shot in the flood plain and several others were seen at the bases of the lateral fans coming out of the walls of the valley. This species is very much shy and more difficult to approach than is lapponicus, a fort first noted last year on the Yogo. Last year I never saw one that I had seen picta, but now that I have specimens in hand, I am sure that I did see them at the Yogo. The conspicuous white rump "sleeve" and the conspicuous white outer tail feathers make a striking pattern in flight that clearly marks them at distances from the more confederate coloured lapponicus, now largely in winter plumage. 9 August Okfilek River - a few seen each day - always in rather low areas - flood plain, uppers were stowed on shore of the alluvial fans but not high up on the sand - not on the walls of the valley and not in the high country transversed on the 9th.
