1908] Grinnell—Biota of the San Bernardino Mountains. 59 
brittle, and his weight sent it crashing to the ground, while the 
eagle had to flap furiously to regain his balance and resume his 
flight. 
On August 2, 1906, we were making our way up the ridge 
between Lost creek and the South Fork, when an adult, and 
almost black, golden eagle alighted, unaware of our presence, 
on a pine stub not more than fifty yards from us. We kept still 
and enjoyed a minute’s close view of his majesty. But he was 
safe as far as our gun was concerned, for we needed no specimens 
of his size to pack through the mountains! 
Falco sparverius sparverius (Linneus). 
American Sparrow Hawk. 
Sparrow hawks were notable for their scarcity in most of the 
region. We found them noticeably common only around the east 
end of Bear lake and the west end of Baldwin lake, where many 
were seen foraging for grasshoppers, August 2 to 4, 1905. One 
was seen on the south slope of Sugarloaf July 3; and on the 
Upper Santa Ana, in the vicinity of our South Fork camp, 6200 
to 6600 feet altitude, I knew of two families being raised both 
in 1905 and 1906. The nest-cavities were in tall dead yellow 
pines. The species was also seen on the lower Santa Ana, June 
11, 1905, and an individual was seen on the desert two miles west 
of Cushenbury sprines, August 11. 
Asio wilsonianus (Lesson). American Long-eared Owl. 
The long-eared owl was met with but onee, at Cushenbury 
springs, 4000 feet altitude, where I ‘‘auxed’’ one as he flew over 
the willow patch on the evening of August 12, 1905. 
Otus flammeola idahoensis (Merriam). 
Dwarf Flammulated Sereech Owl. 
On the evening of July 15, 1905, at Bluff lake, I obtained an 
adult male specimen of this rare species. During the preceding 
two evenings we had repeatedly heard a peculiar note, different 
from that of any other owl we had ever heard. It consisted of 
a single mellow ‘‘whoot,’’ repeated at regular intervals, some- 
thing like the call note of the phainopepla in this respect. These
