_The Wood-Pigeon_ is not often met with, but it does occur, as in the crest of the arms of Bradbury ["On a wreath of the colours, in front of a demi-wood-pigeon, wings displayed and elevated argent, each wing charged with a round buckle tongue pendent sable, and holding in the beak a sprig of barberry, the trunk of a tree fesswise eradicated, and sprouting to the dexter, both proper "]. [Illustration: FIG. 465.--Martlet.] _The Martlet_ is another example of the curious perpetuation in heraldry of the popular errors of natural history. Even at the present day, in many parts of the country, it is popularly believed that a swallow has no feet, or, at any rate, cannot perch upon the ground, or raise itself therefrom. The fact that one never does see a swallow upon the ground supports the foundation of the idea. At any rate the heraldic swallow, which is known as the martlet, is never represented with feet, the legs terminating in the feathers which cover the upper parts of the leg (Fig. 465). It is curious that the same idea is perpetuated in the little legend of the explanation, which may or may {245} not be wholly untrue, that the reason the martlet has been adopted as the mark of cadency for the fourth son is to typify the fact that whilst the eldest son succeeds to his father's lands, and whilst the second son may succeed, perhaps, to the mother's, there can be very little doubt that by the time the fourth son is reached, there is no land remaining upon which he can settle, and that he must, perforce, fly away from the homestead to gather him means elsewhere. At any rate, whether this be true or false, the martlet certainly is never represented in heraldry with feet. If the feet are shown, the bird becomes a swallow. Most heraldry books state also that the martlet has no beak. How such an idea originated I am at a loss to understand, because I have never yet come across an official instance in which the martlet is so depicted. [Illustration: FIG. 466.--Martlet volant.] Perhaps the confusion between the foreign merlette--which is drawn like a duck without wings, feet, or forked tail--and the martlet may account for the idea that the martlet should be depicted without a beak. It is very seldom that the martlet occurs except close, and consequently it is never so specified in blazon. An instance, however, in which it occurs "rising" will be found in the crest of a family of Smith, and there are a number of instances in which it is volant (Fig. 466). _The Swallow_, as distinct from the martlet, is sometimes met with. A swallow "volant" appears upon the arms usually ascribed to the town of Arundel. These, however, are not recorded as arms in the Visitation books, the design being merely noted as a seal device, and one hesitates to assert definitely what the status of the design in question may be. The pun upon "l'hirondelle" was too good for ancient heralds to pass by. [Illustration: FIG. 467.--Swan.]
