htly larger than the last. There are no differences
between the nesting of this form and the last and the eggs are not in
any way different.

SWALLOWS. Family HIRUNDINIDAE

611. PURPLE MARTIN. _Progne subis subis._

Range.--Breeds throughout the United States and temperate British
America; winters in South America.

These large, lustrous, steely-blue Swallows readily adapt themselves to
civilization and, throughout the east, may be found nesting in bird
houses, provided by appreciative land owners or tenants; some of these
houses are beautiful structures modeled after modern residences and
tenanted by twenty or thirty pairs of Martins; others are plain,
unpainted soap boxes or the like, but the birds seem to take to one as
kindly as the other, making nests in their compartments of weeds, grass,
mud, feathers, etc. They also, and most commonly in the west, nest in
cavities of trees making nests of any available material. During June or
July, they lay from four to six white eggs; size .95 x .65.
Data.--Leicester, Mass., June 16, 1903. 5 eggs in Martin house; nest of
grasses.

611a. WESTERN MARTIN. _Progne subis hesperia._

Range.--Pacific coast from Washington south.

The nesting habits, eggs, and birds of this form are identical with
those found in the east.

611.1. CUBAN MARTIN. _Progne cryptoleuca_.

Range.--Cuba and southern Florida (in summer).

Slightly smaller than the Purple Martin and the eggs average a trifle
smaller.

612. CLIFF SWALLOW. _Petrochelidon lunifrons lunifrons._

Range.--Whole of North America, breeding north from the south Atlantic
and Gulf States.

These birds can easily be recognized by their brownish throat and
breast, whitish forehead and buffy rump. They build one of the most
peculiar of nests, the highest type being a flask shaped structure of
mud securely cemented to the face of a cliff or under the eaves of a
building, the entrance being drawn out and small, while the outside of
the nest proper is large and rounded; they vary from
