This Nuthatch is an abundant resident throughout the extensive pine 

 woods of the West, following them in their upward range on the mountains 

 to nearly or quite their limit. Like its eastern representative, it is found 

 frequenting many of the deciduous trees, though it evinces a more marked 

 predilection for the pines. Its habits and notes are so similar to those of 

 the eastern bird that a history of the one would answer perfectly well for 

 the other.

The Red-bellied Nuthatch appears to be of rather uncommon occur- 

 rence in the far West. It was not detected by oitr parties in Utah, though 

 found by Mr. Ridgway in the Wahsatch Mountains in June, where he 

 states it was not common. In the pine woods near Fort Garland, Southern 

 Colorado, I found it breeding in June, and, though less abundant than either
