only places in the San Bernardino mountains where the species 
was detected by our party. Yet it doubtless occurs in much of 
the Upper Sonoran chaparral belt on the Pacific foothills of the 
range. 
Heleodytes brunneicapillus couesi (Sharpe). Cactus Wren. 
Cactus wrens were common at the mouth of the Santa Ana 
canon, near Mentone, June 11, 1905, when several nests were 
noted and a bird taken. One nest contained five considerably- 
ineubated eggs, and another held one fresh egg. The species was 
also noted in the wash at the mouth of Mill ereek, July 16 and 23, 
1907. At the desert base of the mountains, at Cushenbury 
springs, August 10 to 14, several were seen among the tree yuceas 
and a moulting juvenal was secured. 
Salpinctes obsoletus obsoletus (Say). Rock Wren. 
The rock wren was the most widely distributed of any bird of 
the region. Even during the breeding season it seemed utterly 
to ignore zone limitations. It was found in full song June 11, 
1905, alone the water flumes in the lower Santa Ana canon, almost 
at its mouth, and several were seen near the mouth of Mountain 
Home ereek, June 9, 1906. On the very summit of San Gor- 
gonio peak, June 18, 1905, a pair held undisputed possession of 
a retreat among the broken blocks of a granite ledge projecting 
above the snow banks. On the 29th of June, as well as on other 
occasions, adults and full-grown young were very conspicuous 
on the same mountain. On the summit of San Bernardino peak 
on July 12 full-grown young were actually abundant. Their 
tameness and curiosity were remarkable. When I sat down for 
lunch they came up almost within arm’s length. They crept 
about among fallen logs in the tamarack and limber pine forest, 
as well as among the rocks of the barren ridges. They were then 
quiet, save for the ‘‘trill’’ note at intervals. Their inquisitive- 
ness made it difficult to seeure specimens. It was hard to get far 
enough away to shoot, without mutilation. As fast as I re- 
treated they would approach, squatting and bowing, as is their 
habit, at every change of position.
