Range. - A European species which has casually been taken in Greenland. It was liber-ated a number of years ago in Central Park, New York City, and has now become abundant there and is spreading slowly in all directions.

They build their nests in all sorts of locations such as are used by the English Sparrow, wherever they can find a sufficiently large crevice or opening; less often they build their nests in trees, making them of straw, twigs and trash. They lay from four to six pale bluish green eggs; size 1.15 x .85. Two broods are reared in a season.
