the same vicinity with the Least Terns. Evan Davis took full sets of 

 three eggs each at Newport Beach on May i ('97), and on the same 

 day took two young. O. W. Howard took a set of three slightly in- 

 cubated eggs, July 7 (,'95). These indicate the extent of the breeding 

 season, the average being about the first of June. Full sets are almost 

 always of three. 



105— ~2Si. ALgialitis montana (Towns.). 



MountaiQ Plover. 

 Common winter visitant on the interior fields and pasture lands. 

 At times large numbers are offered in the Los Angeles game markets. 



lOt^ — 28.^. Arenaria mela?iocephala (Vig.). 

 Blacl^ Turnstone. 

 Two immature specimens were taken by F. Stephens in the latter 

 part of March, '93, on Catalina Island. I noted it in the same locality 

 toward the last of December, '97. J. W. Daniel, Jr., writes me that he 

 took a specimen at Redondo Beach, June 14, '96. 



107 — 2p2a. Oreoriyx pictus plumiferiis (Gould). 

 Pluroed Partridge. 

 Common resident in the mountainous districts from the highest 

 summits to the foothills. Most numerous in the heavy growth of 

 scrub oak and manzanita which covers the southern slopes of the 

 higher mountains. The " Mountain Quail," as it is locally termed, is 

 not ea.sily flushed and as it generally remains on the steep hill-sides in 

 the almost impenetrable brush, it does not afford much sport to hunters. 

 In time of heavy snow in the mountains, these birds appear in consid- 

 erable numbers in the lower foothills, and individuals have even been 

 seen in Pasadena, three miles from the base of the mountains. The 

 breeding season begins in April. H. Iceland found a nest in the Linda 

 Vista hills west of Pasadena, May 7, '97. It contained ten eggs of the 

 Plumed Partridge and four eggs of the Valley Partridge; all were fresh. 

 The Plumed Partridge was flushed from the nest. I have taken young 

 apparently but a day or two old, on Pine Flats, as late as July 15. 



108 — 2g^a. Callipepla californica vallicola Ridgw. 



Valley Partridge. 

 Abundant resident throughout the countj' except the higher 

 mountains and marsh lands. The range of this species and the Plumed 

 Partridge overlaps in the foothill regions, but the two species never 

 flock together. The Valley "Quail" is //z^ game bird of Southern 

 California. It is particularly abundant in the vicinity of vineyards, 

 and is said to do considerable damage to the grape crop. The breed- 

 ing season begins in April and extends nearly through the summer. 

 H. Robertson took a set of nine fresh eggs near Los Angeles, Aug. 9, 

 '97. Full sets vary from 9 to 23 eggs, usually 15 to 17. 



109 — 2g5. Callipepla gambelii ( Gambel) . 



Gambel's Partridge. 

 H. S. Swarth took an adult male near Los Angeles, Sept. 16, '96. 

 This species occurs regularly not more than fifty miles northward and but 

 a little further to the eastward, so the probabilities are that this bird
