e Pacific.

This species has grayish upper parts, shading into darker on the wings
and tail, and lighter on the throat and upper breast; the underparts are
yellow, and there is a concealed patch of orange on the crown. They are
very abundant throughout the west, where they have the same familiar
habits of the eastern species, nesting in all sorts of locations such as
would be used by the latter. Their nests are made of plant fibres,
weeds, string, paper or any trash that may be handy, being sometimes
quite bulky. Their eggs do not differ in any particular from those of
the eastern bird, except that they may average a little smaller. Size
.95 x .65.

448. CASSIN'S KINGBIRD. _Tyrannus vociferans._

Range.--Western United States from the Rocky Mountain region to
California, and from Wyoming southward.

This species is like the last except that the throat and breast are
darker. Their habits, nesting habits and eggs are indistinguishable from
those of the other Tyrant Flycatchers, and they are fully as courageous
in the defense of their homes against either man or bird, their notes
resembling those of the common Kingbird of the east.

449. DERBY FLYCATCHER. _Pitangus sulphuratus derbianus._

Range.--Mexico and Central America, breeding north to southern Texas.

This handsome bird is the largest of the Flycatcher family found in the
United States, being 11 inches in length. It has a black crown enclosing
a yellow crown patch; a broad black stripe from the bill, through the
eye and around the back of the head, is separated from the crown by a
white forehead and line over the eye; the throat is white shading into
yellow on the underparts. They are abundant in the interior of Mexico,
but can hardly be classed as common over our border, where they nest in
limited numbers. Their nests are unlike those of any of our other
Flycatchers being large masses of moss, weeds and grass, arched over on
top and with the entrance on the side. The three or four eggs are creamy
white, sprinkled chiefly about the large end with small reddish brown or
umber spots; size 1.15 x .85.
