The bluebird is not always a migrant, except in the more northern portions of the country. Some representatives there are always with us, but the great majority winter south and drop out of the spring procession on its way northward, the males a little ahead of their mates, which show housewifely instincts immediately after their arrival. A pair of these rather undemonstrative matter-of-fact lovers go about looking for some deserted woodpecker's hole in the orchard, peering into cavities in the fence-rails, or into the bird-houses that, once set up in the old-fashioned gardens for their special benefit, are now appropriated too often by the ubiquitous sparrow. Wrens they can readily dispossess of an attractive tenement, and do. With a temper as heavenly as the color of their feathers, the bluebird's sense of justice is not always so adorable. But sparrows unnerve them into cowardice. The comparatively infrequent nesting of the bluebirds about our homes at the present time is one of the most deplorable results of unrestricted sparrow immigration. Formerly they were the commonest of bird neighbors.
