discovered. The birds were seen building rapidly on the morning of 

 June 22, but on June 23 they were just as busily engaged carrying the 

 same nest material elsewhere. The new nest was not found. 



No. 5. Pound June 23. In a dense grove of young pines. Nest 

 much like the ones just described, but with a great deal of the moss 

 and not much white fiber. Contained one fresh egg. The nest was 

 deserted when we found it. 



No. 6. Found June 24. In top of a slender pine, about 25 feet 

 from the ground. Nest resting on limbs and against the trunk. Con- 

 tained five young. I '•< ' 



No. 7 (Mus. Vert. Zool. no. 1820). Pound June 24. The only 

 nest discovered that was not placed against the tree trunk. This nest 

 was in a lodgepole pine of larger size than most in this locality, in the 

 fork of one of the larger branches, about three feet from the trunk. 

 Both birds were building here at 1 p.m. At 4 p.m. both birds were 

 seen hard at work carrying the nest material elsewhere. When we 

 ceased watching there was very little of the nest left. On July 5 we 

 happened to pass this place and were surprised to see the nest intact 

 and a bird upon it. It yielded a set of five eggs. This nest is not so 

 bulky as some of the others. Outside diameter, 153 mm. ; inside diam- 

 eter, 77 ; outside depth, 77 ; inside depth, 45. Construction as usual, 

 of twigs, moss, white plant fiber and dry grass. 



No. 8. Pound July 5, about half -finished. In the usual location : 

 against the trunk of a small lodgepole pine, about ten feet from the 

 ground. "We were not able to return to this nest. 



Waxwings were discovered nesting at Doch-da-on Creek, fifty miles 

 down the river, under slightly different conditions from those at Tele- 

 graph Creek. On July 9 two occupied nests were found there, and 

 two apparently of the previous year, all in the same patch of woods. 

 This tract was composed mainly of balsam firs of rather large size, 

 with an admixture of cottonwoods and poplars, and with but little 

 underbrush. While these woods were thus fairly open, they were still 

 much denser than those in which. we found the waxwings nesting at 

 Telegraph Creek. The two occupied nests were less than a hundred 

 yards apart, were exactly alike in location and structure, and when 

 found each contained one fresh egg. Each was near the top of a fir, 

 about twenty-five feet from the ground, supported upon a branch and 

 by surrounding twigs, and close to the trunk. On July 15 one of these 

 nests was taken, together with a set of three eggs. The other contained 

 two eggs, and was left undisturbed. No more eggs were laid in this 

 nest, the female being still incubating the two eggs some days later.
