<note>&hand; <i>Aves</i>, or birds, have a complete double circulation, oviparous, reproduction, front limbs peculiarly modified as wings; and they bear feathers. All existing birds have a horny beak, without teeth; but some Mesozoic fossil birds (Odontornithes) had conical teeth inserted in both jaws. The principal groups are: <er>Carinat\'91</er>, including all existing flying birds; <er>Ratit\'91</er>, including the ostrich and allies, the apteryx, and the extinct moas; <er>Odontornithes</er>, or fossil birds with teeth.</note>

<note>The ordinary birds are classified largely by the structure of the beak and feet, which are in direct relating to their habits. See <er>Beak</er>, <er>Bird</er>, <er>Odontonithes</er>.</note>
