BLACK PHŒBE.
458. Sayornis nigricans. 7 inches.
Slightly smaller than the above, and much darker, almost black on the head and back with white under parts. Their habits are very much the same as above, frequenting old buildings in villages where a stream is near by, or in localities where insect life abounds. Their nest is made the same as above, and eggs are the same.
OLIVE-SIDED FLYCATCHER.
459. Nuttallornis borealis. 7½ inches.
These are nowhere abundant, and in some parts of the country, especially in the central portions, they are very rare. In the western range, they may be found from Alaska to southern California; for breeding places they seem to prefer swampy land, covered with many dead coniferous trees, mixed in with the green trees; their nests are placed well up in the trees and are made of twigs, loosely put together, and lined with small roots and moss. The three or four creamy white eggs are spotted with brown and lilac, forming about the larger end (.85 × .65).
WESTERN WOOD PEWEE.
462. Myiochanes richardsoni. 6½ inches.
Very much like the eastern variety in looks and habits. To be found breeding from Alaska to Lower California. Their nests are placed on horizontal branches, made of plant down, grass and fibers; very compact, and much resembling a knot on the branch. Three or four white eggs with small spots about the larger end (.80 × .55).
