1908] Grinnell—Biota of the San Bernardino Mountains. 1g3} 
found near the mouth of Fish ereek, June 16, 1905, contained 
five fresh eges. It consisted of finely shredded bark strips and 
was located in a deserted flicker’s hole in an incense cedar nine 
feet above the ground. Other nests containing eggs or young 
were found in cavities of dead pines from five to twelve feet 
above the ground. 
Full-grown young in small flocks became numerous by July 
5th. The species was common about the meadows at Bluff lake 
in July and up to September 4. Adults and young were ex- 
tremely numerous in August at the north base of Sugarloaf, 
around the north side of Baldwin lake, about Gold mountain and 
through Holeomb valley. 
A series of twenty-nine specimens was taken, most of them 
being juvenals. Of the ten adult males, but one (No. 6741) has 
the back continuously blue, this being one of the main characters 
of the subspecies anabelae lately ascribed to California by Mr. 
Ridgway (Bds. N. & Mid. Am., Part IV, 1907, pp. 150-152). 
The same specimen shows the chestnut pectoral patch almost, but 
not quite, completely divided by blue medially. This example is 
a July bird and much worn. I believe that wear has a good deal 
to do with the extent of the chestnut. A fresh fall bird is broadly 
chestnut both dorsally and pectorally; but examination of the 
individual feathers, which are blue and then chestnut towards 
their tips, shows that judicious clipping with the scissors would 
make an example of anabelae out of it! Yet the character of 
ereater size of southern California birds is quite evident in the 
San Bernardino series as compared with northern specimens, and 
it may be that these will prove separable on this character alone. 
It is obvious that taking into account all the characters they are 
intermediate between anabelae of the San Pedro Martir moun- 
tains of Lower California and occidentalis of the northwest coast 
region. I am putting them under the latter name for the present. 
Sialia currucoides (Bechstein). Mountain Bluebird. 
The mountain bluebird proved to be fairly common about 
Doble and Baldwin lake, 6700 to 7000 feet altitude, in August, 
1905. <A full-grown juvenal was taken on the 8th, and adults 
at that time were in the midst of the fall moult. An adult male
