240 Birds of San Pedro Martir. [zoe 



Carpodaciis incxicanus fronialis. House Finch. 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 tristis. American Goldfinch. A few winter about 

 the base of the mountain. 



Spinus psaltria. Arkansas Goldfinch. A common resident 

 about the northern part of the peninsula reaching the lower slope 

 of the mountain. 



Spinus lawrencci. Lawrence's Goldfinch. Common with 

 the preceding species; not seen above 4000 feet on San Pedro. 



Spinus pimis. Pine Siskin. Well distributed through the 

 pines on San Pedro, but undoubtedly not common; no nests 

 were found. 



Ammodraimis sandzcichensis alaudinns. Western Savanna 

 Sparrow. A few winter about the base of San Pedro. 



Ammodramus rostratus. I^arge 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
