Howell, T.R. 1950 S. varius ssp. 22 mi. E of Hope, ft., British Columbia May 24 (cont'd). Not until 8:45 did I find the rubber that has a territory here. One was feeding on a hemlock about 8 in. in diameter. Hemlocks and balsams seem to be favored. The bird moved around from tree to tree, usually sticking to hemlocks, but not at all strictly. It made several flycatching forays out over the road, and finally moved down 170 yds where it did the same thing, and finally alighted in a small clump of willows. Here it tapped and did more flycatching, then flew to a huge live fir. There were screams, and the bird disappeared. It is annoying not to be able to find this nest as the birds are so obviously close to it. This is an area of really huge timber, though, and it is very easy to lose sight of a bird on just a short flight. I left at about 10:15 A.M., stopped and listened at 50 mi. SW of Princeton, but heard nothing. 29 mi. SW of Princeton, ft., B.C. May 24 (cont'd) - At the r-n nest at 3:15 P.M. At 3:28 I arrived, looked in several times, went in. Occasionally he threw out chips, or screamed from the nest. After about a/2 hour he came out and hitched up to the top of the tree and stayed for 15 min. before flying off. I heard yathws twice from that direction, and some yelps, but neither bird came to the nest again while I remained, which was until 5:15 P.M.
