contained three heavily incubated eggs. Another June 13, held 
four small young. The nests were all located in the canon bot- 
tom in rose bushes or sage, six inches to three feet above the 
ground. The lazuli bunting was also seen near the head of the 
South Fork, at nearly 8500 feet altitude, though only once, and 
the bird may have been a straggler. It was common in migra- 
tion at Cushenbury springs and Cactus Flat on the desert slope 
of the mountains, August 9 to 18, 1905. Nineteen examples were 
taken. (See pl. 16s.) 
Piranga ludoviciana (Wilson). Western Tanager. 
The western tanager was a common species throughout the 
Transition zone, being perhaps most numerous at its lowest 
border. It was numerous along Mountain Home canon, and 
along the upper Santa Ana from Seven Oaks to Fish creek and 
South Fork canons, where it was noted as high as 8000 feet 
altitude. A nest was found at the mouth of Fish creek, 6500 
feet, on the 17th of June, 1905. This nest was twelve feet from 
the ground at the end of a drooping branch of the Jeffrey pine, 
and contained four eggs in which incubation was at an advanced 
stage. Another nest, found June 13, 1906, was thirty feet from 
the ground in a silver fir, and held three fresh eggs. 
The species was not seen above the fir belt at any point; but 
toward the latter part of August immature individuals were noted 
down into and below the pinyon belt. At Cactus Flat, August 
14 to 17, and at Cushenbury springs August 13, 1905, many 
tanagers were seen migrating; and again, August 21, at the north 
base of Sugarloaf, many were observed. In July tanagers were 
moderately common at Bluff lake and around Bear lake. At the 
latter place they were feeding upon the berries of the western 
juniper. None of the species were seen in the mountains any- 
where after August 22. Nine specimens were obtained. 
Progne subis hesperia Brewster. Western Martin. 
We were surprised to find the western martin a very rare 
species in the San Bernardino mountains. In fact we saw it but 
onee, near the east end of Bear lake on August 2, 1905, when a
