season. ‘The character of the ground at San Ramon, where a 
few were undoubtedly nesting, was a broad sand beach, covered 
with drift-wood, flanked by a few sand dunes, back of which was 
a series of small lagoons of brackish water, thickly grown to 
tules. The eggs of this species which are frequently offered to 
the public by local collectors of Southern California have, so far 
as my observations have gone, always been taken from the nests 
of A. belding?. 
Zonotrichia leucophrys. WHITE-CROWNED SPARROW. 
Zonotrichia leucophrys intermedia. INTERMEDIATE SPARROW. 
Zonotrichia leucophrys gambeli. GAMBEL’S SPARROW. All 
of the white crowns are abundant about the base of San Pedro 
during the winter months, and a few are to be seen in the pines 
during migrations. But few specimens were taken and the 
comparative abundance of the different species was not deter- 
mined. 
Zonotrichia coronata, GOLDEN-CROWNED SPARROW. Quite 
common during the migrations with the white crowns but seems 
to winter farther south than the bulk of these species. All of 
the coronata taken in April were moulting and unfit for specimens. 
Spizella socialis arizone. W¥STERN CHIPPING SPARROW. 
Very abuxdant about the base of the mountain and resident; one 
was shot at 7000 feet elevation May ro. 
Spizella atrigularts. BLACK-CHINNED SPARROW. Rather 
common in the hills from the coast to the base of the mountain. 
I have no specimens from the pine belt, but am sure that its song 
was heard in May, 1887, at 10,000 feet elevation. 
_Junco hyemalis thurbert. THURBER’S JUNCO. It is quite 
- probable that all of the Lower California records of oregonus 
belong to the present species. I found them about the base of 
Gan Pedro in winter with /ownsend?, and met with them in the 
Burro Cafion north of Ensenada April 23, the past season. 
Junco townsendi. "TOWNSEND'S Junco. Very abundant 
throughout the pine region of San Pedro, only reaching the 
lower elevations in winter. ‘The past season the juncos were © 
found building upon our arrival in the pines, May 5, but no
