Generally-speaking, parakeets are 8 to 24 inches in length.  Parakeets have an upright stance when perched; when not flying they move about in the trees using their hooked beak as a climbing aid.  On the ground they walk with a rolling gait, their long tails slightly elevated off the ground.  Both feet are zygodactyl, i.e. two toes in front, two toes behind, a trait shared with [[owl]]s and [[woodpecker]]s.  With the exception of the budgerigar, parakeets use one foot as a "hand" to hold and bring food to its mouth.

Parakeet plumage is also unique in that the brilliant colors are not the result of diet; they are made directly within the feathers by a set of five pigments, or ''psittacofulvins'', a trait found in no other bird species.<ref>http://creation.com/parrot-fashion</ref>
