desire to look at flying birds, requiring that I stop, take off my sunglasses, ... etc. But also because I am not very coordinated on skis. Afterall, it's my second time ever, and here I am, in the boondocks trying to play Dog the Skiing Game. It doesn't work, especially without any way for the skis. At 1900 I gave up after my 9th fall + returned on foot. The snow deteriorated during the morning anyway, melting fast and furiously. At 1500 the temp was +3°C (+1). But a 10°/mph NW wind picked up also, and thick clouds cause air to lay over a solid overcast. Anything but another strong Easterly gale .... Back to migration: perhaps the most satisfying aspect of this event is that we see individuals arrive. Not only were there more seen on the ground yesterday, but this morning when I went out there were just one C. pusilla by the airstrip. 60 min later there were Fluvialis dominica, squatarola, C. mauri and Limnodromus scolopaceus. An hour after that these species were all displaying, however briefly, by the airstrip.
1600 hrs - I returned to the airstrip to see what new arrivals might be found, and amazingly, not only are there no new birds, but I was hard put to find any! The whole nature of the day has changed. A NW wind is blowing strong and the sky is 100% overcast. Few birds are flying. None are displaying. What a rude change. Temperatures at 1600 = 3°C with melt crust on the tundra.

Definitely a warming trend going on. Temperature at 0500 was -2°C. By 1200 it rose to 5°C. Thin fog at 0500, burning off by 0800. Slight wind from E at dawn, increasing gradually to 10 mph by 1200. The morning was gorgeously dripping with melting snow. Today's movement of birds was not equal to yesterday, but it had the same shelter-stelter quality to it. Calcarius in flocks, but even more dispersed + singing. A group of 4 C. mauri by the (Wend) of the runway, in an unceasing flight display, chasing each other up and down the creek, stopping every so often to feed on exposed tundra hummingbirds. I remained around camp until 1830 waiting for the NARL plane to appear to carry me off to Barrow. During the a.m. I tagged local shorebirds, concentrating on Calidris mauri (our Tapi hog and C. mauri spacecount). By 0900 the wind was strong enough to [illegible]
