In Golden Gate Park. San Fran- 

 cisco, while the white-crowned 

 and golden-crowned sparrows are 

 busy on the lawns, faint notes 

 come from the undergrowth, 

 which on investigation proves to 

 be astir with flocks of diminutive 

 bush-tits, though their gray coats 

 disguise them so well that unless 

 you look sharp the oak leaves 

 .seem to be merely rustling in the 

 wind. When watched carefully 

 the little balls of feathers are seen Fig. 58G. 



to be busily looking for insect eggs quite after the fashion of their 

 larger chickadee cousins. Flitting from branch to branch they fly 

 up to light upside down on the underside of a bough, and then 

 without taking the trouble to turn right side up drop down back- 

 wards to catch upside down on the tip of another twig, where they 

 bend double over the terminal buds looking for food. 



In southern California, where the California bush-tits ])reed very 

 abundantly, their long gray hanging nests are common objects as you 

 ride about among the oaks, so common that the birds, which might 

 well be overlooked but for their nests, are known familiarly as 

 ' hang-birds.' 



In a ne.st which came to grief, apparently i)ulle(l down ])y its own 

 weight, I counted over three hundred little feathers in addition to 

 a mass of tine L-'rav moss and oak blossoms.
