370. (759c) Hylocichla guttata nanus (Audubon). Dwarf Hermit 

 Thrush. 



Common winter visitant from the foothills to the coast and on the Santa 

 Barbara Islands. Xoted by J. Grinnell near Pasadena from October 10 (1896) 

 to -May 9 (1896) (Pub. 2, Pasadena Acad. Sci.. 1808. 51). C. B. Linton and 

 myself found it plentiful on Santa Cruz Island in November and December, 1907. 

 and Mr. Linton noted it on San Nicolas Island. March 30. 31, 1910. He also 

 found it common on San Clemente Island from October to April (Condor x, 

 1908. 86). 



371. (759d) Hylocichla guttata slevini Grinnell. Monterey Hermit 

 Thrush. 



Occurs in migrations; so far noted only in the spring, as follows: Five speci- 

 mens by F. S. Daggett near Pasadena, April 8 to 26, 1896 (Condor in, 1901, 

 131). Male by H. W. Marsden near Redlands. San Bernardino County. April 

 16, 1903 (Bishop, Condor vn, 1905, 143). 



372. (759e) Hylocichla guttata sequoiensis (Belding-). Sierra Hermit 

 Thrush. 



Breeds in the mountains above 6000 feet, south to the San Bernardino 

 Range. Winters south to Lower California and Mexico. J. Grinnell found this 

 hermit thrush common in the canons among the north spurs of San Gorgonio 

 Peak, San Bernardino Mountains. Many nests, both old and new, were found 

 in June. 1905 and 1906, above 6300 feet altitude. A nest found in Fish Canon, 

 7000 feet, June 16, 1905, contained four eggs in which incubation was nearly com- 

 plete. Nests found June 18 and June 30, 1905, in South Fork Canon, contained 

 half-grown young. June 12, 1906, Mr. Grinnell found a set of five considerably 

 incubated eggs in South Fork Canon and on June 25, a set of four moderately 

 incubated eggs was found in the same canon. On June 15, 1907, a nest contain- 

 ing two eggs with the parent sitting, was found in the same locality. The next 

 day there were three eggs in the nest, which proved to be the full complement 

 (Univ. Calif. Publ. Zool. v, 1908, 130). 



373. (761a) Planesticus migratorius propinquus (Ridgway ). Westi-:rx 

 Robin. 



Common summer resident in the mountains from 5000 to ( K)00 feet altitude, 

 south at least to the San Bernardino Range. More or less common winter visit- 

 ant to the lower country, south to San Diego and probably occasionally crossing 

 the Mexican line. Breeds mostly in May. Noted by J. Grinnell in the vicinity 

 of Pasadena from October 5 (1897) to April 17 ( 1897) ( Pub. 2, Pasadena Acad. 

 Sci., 1898, 51 ). Observed by W. M. Pierce near Claremont, Los Angeles Count}-, 

 as late as May 3 (1903), and one bird seen by L. Belding at Campo, San Diego 

 County. May 14. 1884 (Land Bds. Pac. Dist., 1890, 256). F. Stephens informs 

 me that the Robin is abundant in the vicinity of San Diego during severe win- 

 ters, but during many winters is not noted at all. In June, 1907, 1 noted several 

 nests containing young birds at Pear Valley, 6750 feet altitude in the San Ber- 

 nardino Mountains. J. Grinnell took a set of three eggs in which incubation was
