A regent parrot is fully grown at about 40 to 42 centimetres, or close to 16 inches, measured end to end. It shares the long silhouette of its Australian parakeet relatives, pairing that length with one of the gentlest temperaments in aviculture, which makes its size a question about flight space rather than about handling strength.
Where the length sits on a regent parrot
The regent parrot's long, tapering tail provides nearly half its total measurement, while its body stays narrow and its head stays small and fine. Adult males carry the richer yellow-olive colouring, with deeper tones across the back and wings, while females are duller and greener overall, though both sexes share the same slim dimensions. A healthy adult generally weighs in the region of 150 to 190 grams, noticeably more than a princess parrot of similar length because the regent is a little deeper through the chest.
Perches, bars, and feet for a slim bird
For all its length, the regent parrot needs furnishings chosen for a medium parakeet's feet, not a large parrot's. Perches of modest diameter, bar spacing in the medium parakeet range, and feeders it can reach without stretching all follow from its narrow build. What does scale with its length is turning room: a regent that cannot turn without its tail striking wire will wear its best feature ragged, so place perches away from cage walls and corners where the tail sweeps as the bird pivots.
A flier first, a climber second
Regent parrots come from open Australian woodland and mallee country, and their build shows it: they are strong, direct fliers who commute rather than clamber. In captivity that translates to a bird that thrives in a long aviary or flight cage and uses climbing toys politely but without the destructive enthusiasm of a true parrot. If you keep one indoors, daily out-of-cage flight in a safe room is not a bonus for this species; it is how a regent parrot keeps the muscle tone its frame is designed around.
Temperament matched to the frame
The regent parrot's reputation for sweetness is earned: it is a quiet, undemanding bird that rarely bites hard and often becomes confiding once it trusts a routine. That softness pairs with a shy streak in new surroundings, so a newly homed regent may sit still and silent for days, which owners sometimes misread as tameness when it is actually a bird taking stock. Give it cover at the back of the cage, a predictable feeding order, and time, and the same bird usually starts greeting you with soft chattering within weeks.
Choosing a regent with adult size in view
An adult regent parrot is a long, light, quiet commitment that can span decades, and its low noise makes it one of the few 16-inch birds realistic for close neighbours. Check a prospective bird's tail condition, because a clean, unbroken tail signals the spacious, calm housing you want its history to include, and ask what flight access it has had. Keep the answers with the bird's records from the start, so that if a regent parrot ever moves to a new keeper, KinsLe Transferrable Profiles can pass on its full profile, preferences, and past in one piece.
