Ordo of Aves

Aves is devided into some ordo. Here the devision of Ordo:

     1.   Stingiformes

They have an almost human appearance, with upright posture, large rounded heads, and large eyes that face forward (most birds have eyes on the sides of their heads). For example is owl. Owls are carnivores, or meat-eaters, and several adaptations make them effective hunters, including a hooked beak for tearing flesh and strong feet tipped with sharp talons, or claws.

2.     Passeriformes

Perching birds (Passeriformes), also known as passerines, are the most diverse of all living bird groups. Perching birds include tits, sparrows, finches, wrens, dippers, thrushes, starlings, warblers, crows, jays, wagtails, swallows, larks, martins, warblers and many others. The estimated 5,500 living species of perching birds account for more than half of all bird species alive today.
Perching birds have a unique foot structure that enables them to grip onto thin branches, twigs, slender reeds and flimsy grass stems. Some species can even grasp vertical surfaces with ease, such as rock faces and tree trunks.
