VOL. IV. | Birds of San Pedro Martir. 243 
were seen as high as 4ooo feet and were probably nesting at that 
altitude. 
Guiraca cerulea eurhyncha. WESTERN BLUE GROSBEAK. 
Very common in all the coast valleys from San Quintin north- 
ward; usually seen in the region of cultivated fields and willow 
thickets. They were seen in the San Telmo up to within a 
short distance of the mountain. 
Passerina amena. V,Azvit Buntinc. Abundant with the 
preceding species, with which it was often seen; one or two were 
seen on top of the mountain. ; 
Piranga ludoviciana. Y,OUISIANA TANAGER. Quite com- 
mon; not seen above 7000 feet. 
Progne subis hesperta. WESTERN MARTIN. Very common; 
nesting in colonies from Valladares, 2500 feet altitude, through- 
out the pines. 
Petrochelidon lunifrons. Ciirk SwaLLow. Common in 
colonies from the coast to the top of the mountain; they were 
found nesting on the sides of huge granite boulders in meadows 
of La Grulla May 13, and later on the eastern side. 
Chelidon erythrogastra. BARN SWALLOw. A few were noted 
on top of the mountain; more common along the coast. 
Tachycineta thalassina. VIOLET-GREEN SWALLOW. Very 
abundant from Valladares to the top of the mountain; nesting in 
hollow pines throughout the region visited. On May 19 a 
large number of females gathered about camp attracted by the 
feathers of some mallards that had been shot for the table. 
Usually the coveted feather was secured without the ceremony 
of alighting, the bird hovering over the pile until a feather was 
selected, and then securing it by a dainty dip of the head and 
immediately dashing off to the nest. A day or so later I shot a 
junco from a tall pine, which in falling detached a number of 
feathers. These were almost instantly secured by a flock of 
these swallows, and before a feather had reached the ground they 
were all appropriated with the exception of one long white 
rectrix which was several times caught and as often rejected. 
Ampelis cedrorum. CkDAR WAXWING. Rather common 
about Valladares, where a specimen was secured May 4. I
