1908] Grinnell_—Biota of the San Bernardino Mountains. — 127 
vireos, and warblers, which were foraging high above in some firs, 
cedars and pines, on a shaded north slope, when I became aware 
of the presence of some smaller birds. Two specimens were ob- 
tained which proved to be Regulus satrapa olivaceus, a species I 
had never expected to find in the region. There must have been 
at least eight individuals scattered about through the tree tops, 
but their great height from the ground prevented my shooting 
any more. Their oceasional faint lisping notes were barely 
audible above the moan of the pines, and altogether these kinglets 
were about the most difficult to follow up of any bird met with. 
One of the specimens (male, No. 7961, Coll. J. G.) is in complete 
juvenal plumage with the sooty olive crown, and the other (male, 
No. 7962) is a bird-of-the-year in nearly full annual plumage. I 
cannot discern the slightest differences between these and corre- 
sponding plumages from Sitka and elsewhere in the northwest 
coast belt. 
This constitutes the southernmost reeord for California, and 
moreover most certainly marks a breeding station. 
Regulus calendula cineraceus Grinnell. Ashy Kinglet. 
The ashy kinglet was not common anywhere and might have 
been easily overlooked, if special pains had not been taken to 
detect its presence. It was much oftener heard than seen; for 
the loud ringing song of the male carried a long distance.’ But 
it is difficult to discern the singers even when one ean trace their 
notes, for they usually keep far up in the heavy foliaged tops 
of the firs. The species seemed to be confined to the extreme 
upper Transition and Boreal zones. Kinglets were noted each 
year in June and July in Fish creek canon at about 7000 feet 
altitude. Here in one particular cluster of tall silver firs two 
male birds’ could be heard answering one another almost any 
time. We spent hours watching for clues as to the nesting site, 
but in vain. The birds were also noted at Dry lake, June 21 
and 22, and at the upper South Fork cienaga, 8500 feet altitude, 
June 27; and at Bluff lake in July and again the last of August 
the species was with certainty observed. Three males were se- 
cured. These specimens present the characters of the race cin- 
eraceus of the arid mountains of the southwestern United States.
