538 OKNITHOLOGY. 



stems of fine grasses, instead of beautiful lichens and mosses, matted 

 together with spiders' webs, and with but a slight admixture of other sub- 

 stances. All its habits, however, especially its deportment, are exactly 

 those of G. virens, while the eggs of the two species are scarcely, if at all, 

 distinguishable. 



At Sacramento we observed in this bird a remai-kable display of attach- 

 ment to its favorite haunts, especially to the place where the nest is built. 

 The nest and eggs of a pair had been taken and the female killed as she 

 flew from the nest; several days afterward, upon revisiting the locality, 

 and happening to look up at the site of the former nest, we were sur- 

 prised to see a new one already completed in the very same spot, the male 

 having found another mate. When we climbed to the nest the male exhib- 

 ited more than usual anxiety, and upon returning the following day it was 

 found to be abandoned, and the only egg it contained broken.
