found jit least up to the pine limit. Except in evincing at all times a marked 

 preference for pine timber, rarely indeed alighting on any of the deciduous 

 trees, its habits and notes seem to corresjDond pretty closely with those of 

 Sphyropicus nuchalis. 



The stomachs of all the specimens examined contained nothing but 

 insects and larvaj. As, however, the structure of the tongue is identical 

 with varitis, the species may possibly, in winter and spring, when other food 

 is scarce, feed upon the inner bark of the deciduous trees, as the common 

 sapsuckers (S. varius and varieties) are well known to do. I never noticed 

 anything, however, which would lead me to suppose this. The nest men- 

 tioned above was dug to the depth of seven inches, and was one and three- 

 fourths inches in diameter. The egg shells had not been removed; and 

 one which is little damaged shows their similarity with those of varius, 

 but appears a trifle larger.
