turally it was essentially similar to the one just described. 

 Dimensions of cavity were: diameter 55mm. (2%8 inches), depth 

 37mm. (l^g inches). A nest found on June 2 contained four 

 eggs and was built of weed stems, bits of dry grass, and lined 

 with weed seed, cowhair, and a bit of rabbit fur. Four other 

 nests found varied in height above the ground all the way from 

 304 to 608 mm. (12 to 24 inches). Of seven nests examined, 

 four contained sets of four, the others sets of three eggs. The 

 first nest was noted May 28 at Quinn River Crossing, the last 

 June 11 on the flats at Thousand Creek. 



As a rule the nests were found by the flushing of the sitting 

 bird. Frequently the parent remained close at hand during the 

 investigation of the nest, often with the feathers of the top of 

 the head elevated and the wings drooping, at intervals uttering 

 a weak "chip." On other occasions the bird would fly heavily 

 away, keeping close to the ground. Once at least the disturbed 

 parent disappeared from view entirely and did not utter a note. 



About the middle of July the appearance of the scores of 

 young ones became noticeable, and Spizella breweri was more 

 than ever in evidence. In certain sage-covered meadows about 

 the head of Big Creek there were hundreds, if not thousands, 

 of the birds. On the broad Leonard and Big Creek flats August 

 4 they were observed in vast numbers, a large proportion of 

 those seen and collected at this time being birds of the year. 



Several flocks were observed in willows along a creek, twit 

 tering together in a most amicable fashion. This peculiarity 

 reminds one of the intermediate and white-crowned sparrows, 

 which, especially in the evening twilight, may be heard singing 

 in a similar manner. 



Junco oreganus thurberi Anthony 



Sierra Junco 



A full-fledged juvenal female Sierra junco was flushed from 



a small pine in a canon near the Duffer Peak meadow (8400 feet) . 



It was rather shy and flew into a tall dead pine. The only note 



it uttered was the low ' ' cheek ! check ! ' ' call-note. 



A second juvenal was noted taking a bath on the edge of a 

 small lake on the same meadow.
