A SUMMER HOME OF THE CALAVERAS WARBLER

The female Calaveras sits very tight, but when once dislodged she 

 instantly disappears; and she returns, if at all, only after the lapse of a 

 tedious interval. Even then she approaches with the greatest caution, 

 ready to dart away again at the first movement of the intruder. In 

 this connection, according to Mr. Bowles, the male has a very curious and 

 amusing habit. If he sees his mate after she leaves the nest, instead of 

 joining her and consoling her in her misfortune, he promptly gives chase 

 in the most furious fashion, driving her from bush to bush as though 

 she had wilfully deserted their treasures. 



As near as we can determine the Calaveras Warbler nests but once 

 in a season in California. Five eggs make the usual set complement, 

 and deposition occurs from May 20 to June 20, according to altitude. 

 Ceanothus cordulatus, snow-bush, is a favorite cover, according to Mr. 

 Chester Barlow, in the middle Sierras; and C. velutinus further north. 

 A favorite lining is soap-root fiber wherever this is obtainable, but dried 

 grasses, horsehair, and feathers are w r elcome elsewhere. Nests are still 

 rare in collections, and are likely to remain so w r hile California chaparral 

 offers such ample asylum to the birds.
