ROCKY MOUNTAIN CREEPER. 
726b. Certliia familiar is montana. 5y 2 inches. 
Range.—Prom Alaska, in the Rocky Mountains, to southern 
California and Mexico, breeding throughout its range. A 
quiet, small, brown colored bird of the deep woods, where 
its lisping note may be heard, if the air is very quiet, and 
one is looking for bird life. When found, it will generally 
be climbing up the trunk of some tall tree, searching the 
crevices of the bark for the small insect life on which it 
feeds; when near the top, a downward flight to the base of 
another tree. Always flying down, and climbing up. Their 
nest is placed in the loose bark, and is made of fiber, moss 
and grass. They lay from four to seven white eggs, spotted 
with chestnut (.58 x.48). 
SLENDER-BILLED NUTHATCH. 
727a. Sitta carolinensis aculeata. 6 inches. 
Range. —Pacific coast region, from British Columbia to 
southern California. These are similar to the White-breasted 
bird of the east. Unlike the above, although these are tree 
climbers, they are as often found coming down the tree 
as climbing up. They build in cavities of various kinds of 
trees, laying five or six white eggs, quite heavily marked with 
brown and lilac (.80 x.60).
