Howell, T.R. 1950 S. varius ssp. 24 mi. SW of Princeton, ft., British Columbia May 30 (cont'd) - 4:56 - r to nest tree, looks in hole on east side, then to nest, looks in 4 times, goes in. 5:24 - n. flies right to nest, squawks; r. looks out, goes back in. N. hitches to one side, waits. In about a minute r. squeezes out, pivots, seems to catch a claw. N. comes up, waits for him to get out of the way: he leaves, n. goes in. 5:34 - screams; n. looks out; after several attempts, n. squeezes out, drops to the branch 3 ft below the nest. 5:25 - n. leaves. I leave too. Neither bird seems to remove anything from the nest, and I presume it is finished. They don't stay in the nest enough to be incubating, I don't think, but they keep going in from time to time. 50 mi. SW of Princeton, ft., B.C. May 31 - 7:40 A.M. - still ice, heavy frost; clear. I went along the lower part of the west slope, following the direction of the creek which runs from the southwest. Just off the road, at 7:45, I saw a nuchalis, in the area where they were yesterday morning. It tattooed several times, then flew over towards the creek. About 1/2 mile or more from the road, at 9:30, I chanced to see a sapsucker fly up into a big dead tree. It was nuchalis. After 15 min of quiet crosswise perching, it flew about 200yds east to a very large, barkless dead tree with a number of holes in it, near the creek. I kept the glasses on it, and was barely able to see it go into a southwest facing hole about 30 ft. up.
