Similar to but slightly 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.

Family HIRUNDINIDÆ 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 × .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 [Illustration 374: White.] [Illustration: Purple Martin.] [Illustration: White.] [Illustration: Cliff Swallow.] [Illustration: left hand margin.] Page 373 this typical nest down to plain mud platforms, but are all warmly lined with grass and feathers. In some localities, cliffs resemble bee hives, they having thousands of these nests side by side and in tiers. Their eggs are creamy white spotted with reddish brown; size .80 × .55 with great variations. Data.--Rockford, Minn., June 12, 1890. Nest made of mud, lined with feathers; placed under the eaves of a freight house. 612.1. CUBAN CLIFF SWALLOW. _Petrochelidon fulva._ Range.--West Indies and Central America; accidental on Florida Keys. 613. BARN SWALLOW. _Hirundo erythrogastra._
