180 VAN DEXBURGH — BIRDS OF SANTA CLARA CO., CAL. [Nov. 17, 



1893, ^i^<^ ^^'^s seen almost daily until September 10. In November 

 and December, 1889, immense flocks passed southward, almost 

 without intermission for days at a time. 



Hespe7'ocichla ncevia. Varied Thrush. 



It usually is not until several weeks after the arrival of our other 

 winter birds that the varied thrush appears at Los Gatos (Jan. 5, 

 1889; Dec. 24, 1889; Dec. 9, 1893). Often it is very common, 

 but during the winter of 1889-90 I saw only three. My latest 

 dates are March 22, 1888, and March 30, 1890. 



Sialia mexicana occidenialis. Western Bluebird. 



This bluebird is a common resident. Its nests may be found 

 from the middle of April until June. In winter it associates with 

 Lawrence's warbler and the pine, green-backed and willow gold- 

 finches. 



Sialia arctica. Mountain Bluebird. 



The mountain bluebird sometimes occurs as a rare winter visit- 

 ant.
