176 VAN DENBURGH — BIRDS OF SANTA CLARA CO., CAL. [Nov. 17, 



Vireo gilviis. Warbling Vireo. 



It is usually early in April that this vireo arrives at Los Gatos. 

 By the middle of that month it becomes common, and a little 

 later nest building begins (April i8, 1890; April 27, 1889). Its 

 eggs are usually four, sometimes only three, and may be found 

 throughout May and the greater part of June (April 26, 1890; 

 June 20, 1889). 



Vireo huttoni. Hutton's Vireo. 



This is a fairly common winter resident near Los Gatos. I 

 believe it retires to the coast to breed. 



Helminthophtla celata luiescens. Lutescent Warbler. 



It usually is not until about the ist of April that this warbler 

 becomes common, although individuals arrive a week or two earlier. 

 In this vicinity their nests seem always to be built upon the ground ^ 

 and those of several years often are not more than a few inches 

 apart. Nestlings may be found from the last week in April until 

 the end of June (April 25-June 30, 1889). Four or five eggs are 

 laid. 



Dendroica cEstiva, Yellow Warblei. 



This is a common summer resident and breeds abundantly, 

 especially on the floor of the valley, in June. 



Dendroica aiiduboni. Audubon's Warbler. 



This warbler occurs in large numbers, from October on through 

 the winter. It is most frequently seen in companies, often with 

 the western bluebird and the various goldfinches, and feeds, to 

 some extent, on grapes. 



Dendroica townsendi. Townsend's Warbler. 



A few specimens of this warbler have been taken at Santa Clara 

 by Mr. J. M. Hyde. I regard them as stragglers from the redwood 

 region near the coast, where this bird is common during migrations. 



Geothlypis tobniei. Tolmie's Warbler. 



I have only one record of this warbler. On May 17, 1890, I 

 came upon a fine male in the foothills west of Los Gatos. Seven 

 days later, in the same place, I saw both male and female car- 

 rying food. Doubtless they had a nest, but careful search failed 

 to reveal it.
