product of the institution's own activities afield, 364 sets, 1410 eggs, all from California; 

 and the income from gifts and exchanges, which was 555 sets, 2001 eggs, of which 421 

 sets, 1576 eggs, domestic and 134 sets, 425 eggs, foreign — a gross total for the season 

 of 919 sets, 3411 eggs. The Director also reported that an actual count had shown 

 20,655 eggs on hand January 1st, 1920, together with nests estimated at 2000 (of which 

 1400 on display). 



The detailed account given below covers the period March 1st, 1919 to March 1st, 

 1920. The brief report of the Museum's own activities is grouped under expeditions 

 rather than accessions, and comment is purely oological. The general account of the 

 1919 field work will be presented in a later issue of the Journal. 



March 18-April 25, 1919. Expedition to Santa Cruz Island. Collectors W. O. 

 Dawson and Robert Canterbury participating. Chief results, a small series each of 

 Island Shrike (Lanius ludovicianus anthonyi) and Raven (Corvus corax sinuatus).

Nest and Eggs of the Golden Warbler, Wilsonia pusilla chryseola 



By E. Raymond Driver 



Eggs of the latter average fully as large as those of mainland birds. The_ claim of 

 C. c. clarionensis, therefore, is discredited. Two sets of Thryomanes bewicki nesophi- 

 lus Oberholser, taken. 



April 7-16, 1919. Trip to eastern San Luis Obispo County, W. Leon Dawson, 

 assisted by Giles E. Dawson. Chief results a handsome series of eggs of Pica nuttalli, 

 together with two nests entire, now installed in the Museum. Also two sets of 

 Prairie Falcon (Falco mexicanus) obtained, one of the "white" type, and the other 

 nearly as dark as a Duck Hawk's. 



April 26-May 15, 1919. Work about Santa Barbara, chiefly by Dawson, Jr., and 

 Canterbury. The former brings in a set 1/17 of the California Woodpecker (Melaner- 

 pes formicivorus bairdi), unquestionably the product of a single pair of birds; and the 

 latter a set, n/5, of the Western Lark Sparrow (Chondestes grammacus strigatus) of
