1912 BIRDS OF SOUTHERN CALIFORNIA 37 



September and leaves in April and the first part of May. Non-breeding birds 

 are frequently seen during the summer months. 



121. (243a) Pelidna alpina sakhalina (Vieillot). Red-backed Sand- 

 piper. 



Common migrant along the coast, occasional on inland ponds. Less plenti- 

 ful in mid-winter. Most abundant in fall from September 15 to November 1, 

 and in spring from April 10 to May 7. I saw several birds of this species at 

 Nigger Slough, Los Angeles County, May 19, 1906, and found them common 

 at Alamitos Bay, December 19, the same year. 



122. (247) Ereunetes mauri Cabanis. Western Sandpiper. 

 Abundant migrant on both fresh and salt water marshes. A few remain 



through the winter. The fall migration occurs in September and October, and 

 the spring migration mostly between April 1 and May 10. C. B. Linton found 

 this species fairly common at San Diego Bay during November, December 

 and January, 1906-7. J. H. Bowles noted it at Santa Barbara, December 5, 

 1909, and February 28, 1910 (Condor xiv, 1912, 9). Mr. Bowles also saw 

 fourteen birds in the same locality, July 11, 1910. 



123. (248) Calidris leucophaea (Pallas). Sanderling. 



Common in flocks on sandy beaches from August 15 to May 15. Occa- 

 sional in summer. Most abundant in spring and fall, the majority of the spe- 

 cies wintering to the southward. C. B. Linton noted this bird on San Nicolas 

 Island as late as May 30, 1910, and I found it fairly common at Hyperion, Los 

 Angeles County, May 31, the same year. H. S. Swarth took a specimen at Re- 

 dondo, Los Angeles Count)', June 4, 1897 (Grinned, Pub. 2, Pasadena Acad. 

 Sci., 1898, 17). 



124 (249) Limosa fedoa (Linnaeus). Markled Godwit. 



Common migrant along the coast, a few remaining in the fall as late as 

 December. The first of the species begin arriving from the north early in 

 Jul)-, and they occur along the beaches in spring as late as the middle of June. 

 H. S. Swarth saw this bird at Alamitos Bay, Los Angeles County, May 16, 

 1901, and Bradford Torrey saw one bird at Santa Barbara, June 4, 1910 (Con- 

 dor xii, 1910, 204). J. H. Bowles saw a bird in the latter locality, Tune 15, 

 1911 (Condor xiv, 1912, 9). 



H. S. Swarth saw the Marbled Godwit at Terminal Island, Los Angeles 

 County, in December, 1899, and C. B. Linton found it common around San 

 Diego Bay as late as December 5. 1906. W. W. Cooke informs me that he 

 does not consider the presence of this species in early December to be proof of 

 its wintering in southern California as there is much southward migration after 

 that time. I have seen no California records for January or February. 



125. (254) Totanus melanoleucus (Gmelin). Greater Yellow-legs. 



Common along the coast and on fresh water ponds during migrations. Less 

 common in mid-winter, north at least to Santa Barbara. Seen occasionally 

 during the summer. Arrives in September and October and leaves mostly in 

 April. G. F. Morcom saw this species at Nigger Slough, Los Angeles County.
