bird box in tree at field

[icle is about the receptacle called a box. For other meanings see box (disambiguation).Boxes are highly variable receptacles. When no shape is described, a typical cuboid box may be expected. Nevertheless, a box may have a horizontal cross-section that is square, elongated, round or oval; sloped or domed top surfaces, or non-vertical sides. A box normally may be opened by raising, sliding or removing the lid, which may be hinged and/or fastened by a catch, hasp, or lock. Whatever its shape or purpose or the material of which it is fashioned, it is the direct descendant of the chest, one of the most ancient articles of domestic furniture. Its uses are innumerable, and the name, preceded by a qualifying adjective, has been given to many objects of artistic or antiquarian interest. See more at Wikipedia.org...]
