Order Macrochires: GOATSUCKERS, SWIFTS, AND HUMMING-BIRDS

Family Caprimulgidae: NIGHTHAWKS, WHIPPOORWILLS, ETC.

Medium-sized, mottled brownish, gray, black, and white birds of heavy build.
Short, thick head; gaping, large mouth; very small bill, with bristles at
base. Take insect food on the wing. Feet small and weak; wings long and
powerful. These birds rest lengthwise on their perch while sleeping through
the brightest daylight hours, or on the ground, where they nest.
Nighthawk.
Whippoorwill.

Family Micropolidae: SWIFTS

Sooty, dusky birds seen on the wing, never resting except in chimneys of
houses, or hollow trees, where they nest. Tips of tail feathers with sharp
spines, used as props. They show their kinship with the goatsuckers in their
nocturnal as well as diurnal habits, their small bills and large mouths for
catching insects on the wing, and their weak feet. Gregarious, especially at
the nesting season.
Chimney Swift.
