How fast can a sun conure fly?

Generally conures range in size, but most of them are like small parrots. Some are about 10 inches head to tail, some are 12; it all depends on the kind that you want. If it's the cage size you're concerned about, conures do need a lot of room to flap their wings and play around. They are very comical and charismatic creatures, and like to have room to play and be silly. The minimum size cage for a conure should allo him/her enough room to stretch their wings.
It depends on the type of conure(jenday, sun, green cheek) but conures are usually about 9-10 inches including their tail feathers.
There are many types of conures in the world of parrots. They range in size from small (black capped conure), to medium in size. Some conures have recently been reclassified out of the aratinga sub category; the Queen of Bavaria conure is one of those and has also been renamed to The Golden Conure.

The average size for a conure is approximately 10 to 12 inches from top of head to end of tail.

Conures can be identified by a bare white eye patch of skin around the eye only. They have both light and dark colored beaks and feet.

They are one of the hardiest breeds of parrot, and although they are loud, they are really great 'starter' birds for the person who wants a companion parrot.
