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 twenty feet below 
the surface of the ground in an old shaft or tunnel. 
Sayornis nigrescens. BLACK Puaise. Quite common along 
all of the water courses and resident as high as 3000 feet at least; 
a single pair were nesting at La Grulla May 22. 
Contopus borealis. Otive-SIDED FLycaTcHER. 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. 
Contopus richardsont?. WrsteRN Woop PEWEE. Very 
common in San Pedro; one that had its nest in a large pine over 
our camp on the night of May 28, kept up a calling at intervals 
of thirty minutes all night. 
Empidonax cineritius. Sv. Lucas FLYCATCHER. 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 £. wrightii might choose. 
_ Empidonax pusillus. Lr FLYCATCHER. Seen only 
during migrations. 
Otocoris alpestris chrysolema. 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 year. Mr. 
Townsend’s types of pallida 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 chrysolema, 
_ Otocoris alpestris pallida, Sonoran Hornep Lark. My 
notes were given to Mr. Bryant and published by him under the 
name of rubea. It seems, however, from the material I have at 
present that pa//ida is the form found at San Quintin during the
