Early in August they were fairly common at Hemet Lake. 

 Here they frequented certain open, gravelly areas near the 

 shores of the lake, where there was a thin growth of low weeds 

 in which the birds fed in scattered flocks of eight or ten. 



Twenty-six specimens were taken, from the following points : 

 Cabezon, five adults (nos. 1636-1640), Hurley Flat, one (no. 

 1641). Schain's Ranch, one (no. 1865), Banning, two juvenals 

 (nos. 2041, 2042). Kenworthy, five adults (nos. 2306, 2307, 2310- 

 2312), Vandeventer Flat, one adult (no. 2308) and one Juvenal 

 (no. 2309), Tahquitz Valley, one immature (no. 2849), Hemet 

 Lake, nine immatures (nos. 2957-2965). The Tahquitz Valley 

 and Hemet Lake specimens are all in complete first winter 

 plumage, no adults being secured after the post-nuptial molt. 

 The female taken with the set of eggs near Vandeventer Flat 

 (no. 2308) is distinctly marked with black on the chin, quite 

 as conspicuously as many male birds. 



Junco oreganus thurberi Anthony 

 Sierra Junco 



A common species in the higher parts of the mountains, from 

 the lower edge of Transition upwards. The lowest point at 

 which juncos were seen was Schain's Ranch (4900 feet). At 

 Strawberry Valley, Tahquitz Valley, and Round Valley, and in 

 the Santa Rosa Mountains, both at Garnet Queen Mine and on 

 the ridge from Santa Rosa Peak to Toro Peak, they were numer- 

 ous. 



Two nests were found at Schain's Ranch, June 22. They 

 were in like situations, on the ground, near small streams, and 

 well hidden in the shrubbery. One contained two eggs and two 

 newly hatched young, and the other held three incubated eggs. 

 Another nest was discovered in Tahquitz Valley, July 21. This 

 was placed in a depression in a bank, adjoining a little stream, 

 and concealed by overhanging grasses and ferns. As large young 

 were seen by the third week in June, it accordingly seems prob- 

 able that a second brood is sometimes raised. On Thomas Moun- 

 tain. August 16 to 20. they were gathered in relatively large 

 flocks. Specimens taken at this time were well advanced in the 

 annual molt.
