Howell, T.R. 1950 S. various ssp. 50 mi. SW of Princeton, ft., British Columbia May 30 (cont'd). -catching, but went to the ground occasionally. Finally, about 11:50, the ruber flew far up the creek, to the southwest, and the S nuchalis followed. They went over the shoulder of the ridge, then came up again, and worked back towards me. Again they went off [illegible] to the southwest, finally across the creek to far over on the green side, where I saw the two in the very top of a dead spruce over 200 yds away. I could barely make them out. Then the ruber went farther southwest, and I lost sight of it; the nuchalis remained in the tree a few moments, then went a little to the east, and I lost sight of it too. At least 1/4 mi. was involved in this activity, which lasted until 12:05. I would guess that this is the territory of a nuchalis pair (both were typical), although it is a large one. The ruber may have wandered up from the west, but its unwilling- ess to leave may mean that its own territory is not far away, although far enough so that no defensive attitude was aroused. The weather was almost completely clear. 29 mi. SW of Princeton, ft., B.C. May 30 (cont'd) At 3:15 I was by the r-n. nest. 4:03 - r. arrives, looks in 3 or 4 times, preens, flies off. 4:15 - n. up from 100yds down the slope; squawks at the nest, hitches above it, flies off 30 yds up the slope, gives 3 yelps.
