240 Birds of San Pedro Martir. [ZOE 
Carpodacus mexicanus frontalis. Housk Frncu. Abundant . 
resident in all of the lower valleys; on San Pedro a few only 
were found upon our arrival, May 5, but they soon became 
abundant, especially about the meadows. Specimens from that 
region are not materially different from Southern California skins 
in my collection. : 
Spinus trist’s. AMERICAN GotprincH. A few winter about 
the base of the mountain. 
Spinus psaltria, ARKANSAS GoLpFINcH. A common resident 
about the northern part of the peninsula reaching the lower slope 
of the mountain. 
Spinus lawrencet, LAWRENCE'S GOLDFINCH. Common with 
_ the preceding species; not seen above 4ooo feet on San Pedro. 
Spinus pinus. PINE SISKIN. Well distributed through the 
pines on San Pedro, but undoubtedly not common; no nests 
were found. 
Ammodramus sandwichensis alaudinus, WESTERN SAVANNA 
Sparrow. A few winter about the base of San Pedro. 
Ammodramus rostratus. LARGE BILLED SPARROW. Very 
common in fall and winter all along the coast, but never wander- 
ing far from salt water. It is considerable of a mystery to me to 
locate the nesting grounds of this species. Thousands of birds 
are seen in all of the salt marshes along the coast from the north- 
ernmost limit of its range. No decrease is noticed in their 
numbers until the nesting season approaches, when they suddenly 
disappear and are not again noticed until August, when they 
make their appearance with young, and are common about the 
old haunts until the following spring. 
On one occasion Mr. A. M. Ingersoll discovered at San Diego 
a bird carrying food for its young, but was unable to find the 
nest owing to the great distance to which the bird flew with its 
load. On the beach in April, 1887, I shot a female at San 
Ramon that had undoubtedly left her eggs but a few moments 
_ before. As the birds were scarce at that point and I was unac- 
quainted with the rarity of their eggs, I made no effort to find 
their nests, and, although I have patiently searched for them 
. ever since, I have never again seen birds during the nesting
