In suitable loculities throughout California, as else- 

 where in the United States, the Yellow-headed Black- 

 bird breeds abundantly. The interior valleys east of the 

 Coast Range are his favorite haunts ; there, except dur- 

 ing the nesting season, he may be found picking up insect 

 food in the newly harrowed ground. Grasshoppers, big 

 black wingless crickets, all sorts of marsh insects, and 

 the larvsD and eggs of beetles form his bill of fare ; and 

 much does the farmer owe to his good services. When 

 the winter rains have ceased and the warm spring sun- 

 shine floods the valleys, the large flocks of these hand- 

 some birds leaving the farms and fruit ranches betake 

 themselves to the tule marshes, where their noisy wooing 

 can be heard far and wide. While the male rocks and 

 sings on the tall reeds, the soberly gowned fenuile is 

 busy building a nest among the swaying rushes. First 

 she brings heavy, wet pond-weed and marsh-grass, and 

 with it winds several of these together, weaving it in 

 and out and making a firm sui)port for the superstruc- 

 ture. Bits of dried rushes and last year's tule are 

 twisted in to form the walls, which are then warmly 

 lined with tlu^ finer marsh-grass and pond-weed. No 

 feathers or other animal nuitter are used in it, but occa- 

 sionally a little plant down, as iftlic blossom had ri[)ened 

 after having been caught accidentally in the weaving.
