Howell, T.R. 1950 S. varius ssp. 29 mi. SW of Princeton, May 28 (cont'd). apparent reason and flew off. ft., British Columbia I was close by, but half behind a large tree, and quite motionless. The ? n. remained for a few moments, then flew off also. I feel sure this is the same r-η. pair as is nesting up higher on the slope, but there is no way to be absolutely certain. I went up on the more western slope at about 4:00 P.M. Around 4:30 or 4:45 (I forgot my watch) I heard yelps, and saw a nuchalis at the nest site described several days ago. More yelps-- the bird flew over to a large dead tree about 75yds away, where another nuchalis was - squawks. One, apparently a δ, crossed out approached the other lengthwise on a branch, squawking, fluttering his wings, bobbing slightly, crown feathers raised. The other was not receptive, and did not assume a copulatory pose. I am not even sure it was a ?, but there was no sign of aggression. They hatched crossed out around, and the same actions were repeated - no copulation. One flew off, the other paused, followed, the flew far off up the slope and I lost track of the other. Neither went to the nest site in the next 20 min, and I left, about 5:15 A.M. 50 mi. SW of Princeton, ft., B.C. May 29- Here at 4:27 A.M. - overcast, drizzly. First tattoo, 4:52; 5:01 - repeated several times until 5:20. It was then getting really light, but
