The Wheatear is a European bird, but this sub-species is found in Greenland and occasionally in Labrador.

Their habits are about the same as those of the Bluebird. They feed upon insects, larvæ, fruits, berries and some seeds. They are essentially ground birds and are usually found in rocky country.

Nest.—Their nests are made of grasses, hair or any rubbish obtainable, and are hidden in the innermost recesses of crevices among rocks, in deserted Bank Swallow nests or even in rabbit burrows.

The four to six eggs are pale greenish blue, a little brighter in shade than those of the Bluebird. They measure .94 × .60

These beautiful, gentle and well-known birds spend the winter in the southern parts of the United States and north to the snow line; some more hardy than the rest are found throughout the winter in southern New England.

Call.—A short sweet warble; song, a continued warbling.

Nest.—In holes in trees, particularly in orchards, in bird boxes or crannies about the buildings. The bottom of the cavity is lined with grasses for the reception of the four or five pale bluish eggs, which measure .84 × .62.
