Howell, T.R. 1950 S. various ssp. 17.5 mi. S. of Quesnel, ft., British Columbia June 13 (cont'd.) this spot at 3:45 P.M. It was very hot, probably around 90° in the shade. The young were very quiet until a parent came up. The ♂ was up first, went in, cleaned the nest to a dead aspen about 20 yds away and began screaming at me. His rectal temper- ature was 41.8°C. In about 6 min. the ♀ came up to the nest and I collected her; she was 42.0°C. I hate myself for leaving the young to starve in the nest, but there is no way I could get to them as the nest is high up in a smooth, large trunk. Only 5.2 miles north is where I saw ruber this morning. Alexandria, 1800ft., 28 mi. S. of Quesnel, B.C. June 13 (cont'd.) At 5:30 P.M. I went up back of the ranch house in an aspen-birch-fir woods and found a nest about 40 ft. up, facing NW, in a mature aspen—a tall one about 14" in diameter. One parent a ♀, I think, is a typical nuchalis, and the other is ruber. Right next to the nest is a large clump of birches that are riddled with workings. Both birds made 3 or 4 visits during a 20 min. interval; the ruber cleaned the nest once. June 14—screams and a couple of tattoos from the aspen grove by the meadow, and again I saw typical nuchalis feeding at an alder. I visited the r-n. nest here, and saw the ruber plainly; it looks perfectly typical.
