1908] Grinnell—Biota of the San Bernardino Mountains. 85 
been noted in the adult European bird. This seems of genetic 
significance. 
We found young and adult nuterackers together foraging in 
small companies of five to ten. They were easily attracted within 
range, by the collector uttering a harsh rasping sound between 
the tongue and roof of the mouth. 
The species was seen on San Bernardino peak July 12, 1905. 
Several were seen on the north side of Gold mountain, 7500 feet 
altitude, August 26. Down on the lower edge of the pinon belt 
at Cactus Flat, 6000 feet, a pair were seen to visit a spring on 
August 16. The species was frequently seen in June and July 
at the head of the Santa Ana near the mouths of Fish ereek and 
South Fork, and down to 6000 feet altitude. It was seen once 
at Bluff lake, and a few were seen at a spring on the north side 
of Sugarloaf at-8500 feet altitude; also a few at a cienaga at the 
north base of the same mountain at 7500 feet elevation. An 
adult male taken August 26, 1905, on Gold mountain, has the fall 
moult nearly completed. 
Eleven specimens were secured. 
Cyanocephalus cyanocephalus (Wied). Pinon Jay. 
The pinon jay was met with only among the arid northern 
ridges and valleys of the San Bernardino mountains. The first 
were met with at the east end of Bear lake, August 13, 1905, 
where a few in company with Brewer blackbirds were moving 
through the pines along the shore. The same day a very large 
flock containing perhaps 100 birds was encountered at the east 
end of Bear valley. In the vicinity of Doble and about the north 
shore of Baldwin lake, 6700 to 7200 feet altitude, pifon jays 
were the most conspicuous birds to be seen during August. They 
seemed to belong normally to the pion belt, although the troops 
when on foraging excursions wandered out on to the meadows 
and sage flats far from conifers of any sort. None were seen 
lower down than Cactus Flat, 6000 feet, on the desert slope, 
where a small flock was seen August 9. This was well within the 
pinons. 
These jays were remarkable for their indifference to a per- 
son’s presence, and unless on the open ground paid little atten-
