All our songsters belong to this order, and the term " Song Birds" is sometimes employed as synonymous with Perching Birds. But this practice is confus- ing, as many of these birds (including the en- tire Flycatcher and Crow families) do not sing at all. In size they range from very small birds (Kinglets, 4 inches long) to medium, — the Crow family being the only one with species much larger than the Robin.
