. Annual report of the New York State College of Agriculture at Cornell University and the Agricultural Experiment Station. New York State College of Agriculture; Cornell University. Agricultural Experiment Station; Agriculture -- New York (State). Rural School Leaflet 112! sort of box may be selected by a pair of bluebirds for their home, but the one that looks most like the old hollow liinb in the orchard will prove most attractive. The entrance hole should be made on one side near the top, and should be about an inch and a half in diameter. No nesting material should be placed in the box, unless perhaps a little sawdust in order to make it seem more like a real cavity. When the bluebirds have once found the box, they may return to it year after year. The bluebird builds a well-fonned nest of rootlets and grasses, and from three to five pale blue eggs are laid in it. Both birds take turns sitting on the eggs, which hatch in less than two weeks. The young remain in the nest about two weeks longer; and for some time after they have left the nest, they are fed in the trees by their parents. Before the}^ are able to shift for themselves, however, the parent birds begin a second nest. Occasionally they pull out the first nest and build the second in the same box, but oftener they move to another site; so that it is always well to provide more than one box. The 3'oung bluebirds when they leave the nest do not resemble either of their parents, for their backs are marked with whitish and their breasts have dark spots. In the latter respect they show their relationship to the true thrushes, all of which in some plrunage have spotted breasts. In the late summer and fall the bluebirds gather in scattered flocks, often associating with chipping sparrows, and are found all through the open farming country. Their call at this season, tur-ree, tur-ree, while quite as friendly as the note of spring, has just a tinge of sadness, and seems as much a part of the fall months as are t
