PERCHING BIRDS 
462. Western Wood Pewee. 
Myiochanes richardsoni richardsom. 
Range.— Western United States from the 
Plains to the Pacific, and from Manitoba south- 
ward, wintering south of the United States. 
The nesting habits of this bird are the same 
as those of the eastern Pewee, but their nests 
are more strongly built and generally deeper, 
and without the outside ornamentation of 
lichens. They are saddled upon horizontal 
branches, like those of the preceding, as a 
rule, but are also said to have been found in 
upright crotches like those of the Least Fly- 
catcher. Their three or four eggs cannot be 
distinguished from those of the eastern Wood 
Pewee. 
462a. Large-billed Wood Pewee. Myio- 
chanes richardsoni 'peninsulas. 
Range. — This species which differs from the 
last only slightly, as is indicated by the name, 
inhabits the peninsula of Lower California; its 
nesting habits and eggs will not differ from those of the other Pewees 
Yellow-bellied Flycatcher 
Acadian Flycatcher 
463. Yellow-bellied Flycatcher. Empidonax flaviventris. 
Range.- — North America, east of the Plains and north to Labrador; winters 
south of the United States. 
This species is slightly larger than the Least Flycatcher and is 
more yellowish above and below, the breast being quite bright. 
While common in some districts it is quite shy and frequents 
thickly wooded regions, where it is not very often seen. They 
nest near or on the ground among rocks or roots of fallen trees, 
chiefly in swampy places; the nests are made in bunches of 
moss, hollowed out and lined with very fine grasses. Their four 
eggs are creamy or buffy white, spotted and speckled about the larger end with 
reddish brown and gray; size .68 x .51.

464. Western Flycatcher. Empidonax difjicilis difpcilis. 
Range. — Western North America, from the Rocky Mountain region to the 
Pacific, and north to Alaska; winters chiefly south of the United States. 
This Flycatcher, which is similar to the last, nests in similar 
locations as well as in many others, such as crevices and fissures 
in rocks, holes in banks, cavities in trees, rafters in buildings, 
etc. The nests are variously made, but consist chiefly of fine 
grasses, weeds and fibres. The eggs are as a rule similar to 
Creamy white those of the last species and cannot be distinguished.
