arts of the wings and
tail, and their quills are reddish. Neither sex has the red crescent on
the back of the head, except in the case of hybrids between the two
species, but the male has red moustache marks. There are no differences
in the nidification between this species and the preceding, but the eggs
of this average a trifle larger (1.15 x .90).

413a. NORTHWESTERN FLICKER. _Colaptes cafer saturatior._

Range.--Pacific coast, breeding from Oregon to Alaska.

This is a much darker variety of the Red-shafted Flicker, but its
nesting habits or eggs do not differ in any way.

414. Gilded Flicker. _Colaptes chrysoides._

Range.--Arizona and southward through Mexico to southern Lower
California.

This pale species has the yellowish lining to the wings and tail as in
the Flicker, but has a pale cinnamon brown crown, no crescent on back of
head, and the male has red moustache marks. It is a common species in
all localities where the giant cactus abounds, and shows a preference to
nesting in these strange growths, to any other trees. Their habits are,
in all respects, the same as those of the other Flickers and their eggs
cannot be distinguished. Size 1.10 x .90.

414a. SAN FERNANDO FLICKER. _Colaptes chrysoides brunnescens._

Range.--Northern Lower California.

This is a slightly smaller and darker variety of the Gilded Flicker.

415. GUADALUPE FLICKER. _Colaptes rufipileus._

Range.--Guadalupe Island.

Similar to the Red-shafted Flicker, but with the crown darker and the
rump a solid pinkish white. They are common in a large cypress grove in
the middle of the island, but rarely found on any other portions. The
eggs have been described by Mr. Walter E. Bryant, who found them
breeding on the island, to be indistinguishable from those of the others
of the genus.

GOATSUCKERS, SWIFTS, AND HUMMINGBIRDS.

Order XVI. MACROCHIRES.

GOATSUCKERS, Family CAPRIMULGIDAE.

Goatsuckers are long winged birds, with small bills, but with an
extraordinarily large mouth, the opening of which extends beneath and
beyond the eyes. They are chiefly dusk or night fliers, their food
consisting of insects which they catch on the wing. Th
