Tringa canutus Linnaeus. Knot. The latest date of occurrence of this compara- 
tively rare migrant during the spring migration in this state that has been recorded is 
May 10, as given in “The Game Birds of California”. There are, however, in the Acad- 
emy collection a number of specimens of adults of this species taken in Alameda Coun- 
ty, supposedly on the San Francisco Bay shore, between May 10 and 24, a male and two 
females having been taken on the latter date. The plumages of these specimens are 
in all stages between winter and breeding. 
Pisobia maculata (Vieillot). Pectoral Sandpiper. There are very few records for 
California of this species and the two males taken by R. H. Beck near Los Bafios, Mer- 
ced County, on September 15 and 18, 1908, and a female from Point Sur, Monterey Coun- 
ty, taken by E. W. Gifford on September 9, 1911, add materially to the meager list of 
occurrences. 
Ereunetes ‘mauri Cabanis. Western Sandpiper. This species is an abundant 
spring and fall migrant along our coast and to a certain extent in the interior as well, 
wintering from San Francisco Bay southward. The return movement from its northern 
breeding grounds has been usually recorded as reaching the latitude of San Francisco 
toward the end of July, but there are many specimens of both sexes in the Academy 
collection taken as early as July 13 to 15, all adults from Alameda County, and four 
males from Monterey taken July 16. Incidentally there are numerous juveniles taken 
in August. 
Totanus flavipes (Gmelin). Lesser Yellow-legs. The Academy is singularly for- 
tunate in having seven specimens of this bird of California take, as there are but nine 
other occurrences recorded within the state’s borders. Of the seven, one male and one 
female were taken on September 21, two males and two females on October 6, 1908, 
near Los Bafios, Merced County, and one male on August 19, 1907, on Monterey Bay. 
As this species can only be distinguished from its close relative, the Greater Yellow- 
legs, by its smaller size, and as both species are wary and difficult to approach suffici- 
ently close to admit of positive identification, the Lesser Yellow-legs may have occasion- 
ally been mistaken for the commoner form. It is probably not as rare a migrant in this 
state as absence of records would imply, and a systematic and continued search for it 
in proper localities would in all likelihood develop this fact. 
Numenius americanus Bechstein. Long-billed Curlew. In “The Game Birds of 
California” this species is mentioned as occurring in the San Joaquin Valley throughout 
the year, but is not recorded as breeding there. The Academy collection contains spe- 
cimens from Merced County, taken in July and August. The above authority also gives 
it as migrating southward along the California coast in July, and says that these birds 
“. .. do not seem to reach inland spots such as the shores of San Francisco Bay until 
August or September...” This statement is rather contradicted by the presence in 
the collection of a male taken in Alameda County, July 15, 1910, and two females from 
the marsh at Alviso, Santa Clara County, taken on July 27, 1909. 
Aegialitis semipalmata (Bonaparte). Semipalmated Plover. This bird is a very 
common migrant along the coast of California and there are abundant records. Among 
the specimens in the Academy collection, however, are several which help to determine 
the time of arrival in the San Francisco Bay region of the south-bound migrants from 
their breeding ground in the north. Most of the published records of this species at 
this period of migration are from southern California, but there are two females in the 
Academy taken in Alameda County, on July 13, 1909, and several in early August. 
Archibuteo lagopus sancti-johannis (Gmelin). American Rough-legged Hawk. 
There is one specimen of this rare visitant to thig state in the collection, this being a 
male taken near Los Bafios, Merced County, on December 1, 1908. 
Most of the above records were made by R. H. Beck and BE. W. Gifford at 
times when they were occupied in collecting more or less steadily in one spot, 
and they clearly prove that protracted observations in suitable localities would 
result in many additions to our geographic and seasonal records for the state 
of California. 
San Francisco, California, November 27, 1920.
