Resident but not in large numbers. C. A. Keeler (3) recorded this species 
from San Nicolas. On San Clemente it is rather rare and confined to the north- 
west coast. C. B. Linton (9) found an unfinished nest there March 20, 1907, and 
I saw a single bird March 27, 1915, the only one during a three weeks stay. At 
Catalina I have seen occasional birds during April, and J. Grinnell (4) noted 
three in December, 1897. It was present, but not in numbers, on Santa Cruz 
when A. van Rossem and I were there in late April, 1911. A nest which we kept 
under observation contained pipped eggs April 26. Linton (10) found it fairly 
common here during November and December, 1907. C. P. Streator (6) took 
two adults on Santa Rosa in July, 1892. 
114. Myiochanes richardsoni richardsoni (Swainson) 
WESTERN Woop PEWEE 
Contopus richardsonii (1) Grinnell, Pasadena Acad. Sci., 1, 1897, pp. 10, 15. 
Horizopus richardsonii (2) Mearns, Bull. U. S. Nat. Mus., tyr, 1907, p. 142. 
Contopus richardsoni richardsoni (3) Linton, Condor, x, 1908, p. 127. 
Myiochanes richardsoni richardsoni (4) Willett, Pac. Coast Avif., 7, 1912, p. 64. 
A not uncommon migrant. L. M. Huey (MS) shot a female on the Corona- 
dos, May 18, 1913, and the same day saw about four others flyeatching from the 
large boulders near the water. On San Clemente, J. Grinnell (7) saw one June 
3, 1897, and considers that although rather late in the season, it was a migrant. 
He took a female on San Nicolas Island, May 20, and a male on the 23rd. C. B. 
Linton (3) states that he heard several among the pines of Santa Cruz Island in 
December, 1907, but collected no birds. As this is two months after they leave 
southern California, and there is not another winter record for the state, it is ex- 
tremely likely that Linton was mistaken in supposing that the notes which he 
heard emanated from this species.
