238 Birds of San Pedro Martir. [zoE 



feet. At Valladares they were given to nesting in all of the 

 deserted mines, and I have found their nests twent}^ feet below 

 the surface of the ground in an old shaft or tunnel. 



Sayornis nigrescens. B1.ACK Phcebe. Quite common along 

 all of the water courses and resident as high as 3000 feet at least; 

 a single pair were nesting at I^a Grulla May 22. 



Contopits borcalis. Olive-Sided Fi^ycatcher. Abundant 

 throughout the pine belt, one in my collection from that region 

 has a large, clear, white patch on the throat, lacking entirely the 

 streaking common to that species. 



Contopiis richardsonii. Western Wood Pewee. Very 

 common in San Pedro; one that had its nest in a large pine over 

 our camp on the night of Maj' 28, kept up a calling at intervals 

 of thirty minutes all night. 



Empidonax cineritius. St. Lucas Fi^ycatcher. Very com- 

 mon all over the mountain, especially along the streams and in 

 the willows. It was evidently nesting at the time of my visit in 

 May, but no eggs were taken. From its preference for willow 

 thickets at this time I would expect to find its nests in such 

 places as E. zvrightii might choose. 



Empidonax pusillus. L,ittle Flycatcher. Seen only 

 during migrations. 



Otocoris alpestris chrysolcBma. Mexican Horned Lark. 

 Along the coast as far as Colnett, at least the horned lark belongs 

 to this race as shown by specimens in my collection. At San 

 Quintin, however, fifty miles further south, pallida is the race 

 met with during the breeding season if not the entire j^ear. Mr. 

 Townsend's types of /a///^a came from the region just east of 

 San Pedro, which with the San Quintin record on the west led 

 me to expect this form from the mountain meadows. No larks were 

 met with, however, until the eastern edge was reached; here a 

 few were taken that were all true chrysolcema. 



Otocoris alpestris pallida. Sonoran Horned Lark. My 

 notes were given to Mr. Bryant and published by him under the 

 name of rubca. It seems, however, from the material I have at 

 present ihiii pallida is the form found at San Quintin during the
