The Red-breasted Nuthatch is the same familiar slate- 

 gray bird in California that he is in the oak groves of 

 Illinois or the forests of Maine. In California he follows 

 the footsteps of spring up into the mountains, and makes 

 his nest in the natural cavities of dead trees, coming 

 dovra to milder levels when the snow flies. Yet he is a 

 hardy little fellow and loves the cold, and only the de- 

 crease of insect life induces him to seek a fatter larder 

 elsewhere. The nesting habits of this species are essen- 

 tially like those of the slender-billed nuthatch.
