The Adult Size of a Timneh Parrot
A fully grown timneh parrot reaches about thirteen inches in length from crown to tail tip, making it a compact but substantial medium parrot. The timneh is the smaller of the two African grey types: a Congo grey stands noticeably taller and heavier, while a timneh has a stockier build, darker charcoal plumage, a maroon-brown tail rather than a scarlet one, and a pale horn-coloured upper beak instead of solid black.
Weight tells the story better than length with a timneh. A healthy adult carries a firm keel bone under a well-muscled chest, and a bird that feels light or sharp-boned at handling time deserves a weight check on a gram scale. Owners who weigh a timneh weekly on a perch scale catch slow declines long before the eye can see them, which matters because this species hides illness skilfully.
Wingspan and Why It Changes the Cage Decision
The wingspan of a timneh parrot is roughly double its body length, and that single fact should drive the cage decision. A cage that fits the bird standing still can still be too small once the timneh stretches both wings, turns around on a perch, or flaps for exercise. Bar spacing must suit a timneh's head width, perches should vary in diameter for foot health, and the longest dimension of the cage matters more than decorative height.
Inside that cage, a timneh needs room for separated zones: a sleeping perch placed high, food and water bowls away from droppings, and hanging toys positioned so tail feathers are not constantly brushing bars. Tail damage in a young timneh is often a cage-size signal rather than a behaviour problem. A play stand outside the cage, with its own toys and food cups, extends the bird's usable territory during out-of-cage hours.
Growth From Youngster to Full Size
A timneh parrot reaches close to adult dimensions within its first couple of years, though the bird keeps filling out in chest muscle and confidence well after the tape measure stops moving. Young timnehs have darker eyes that lighten with maturity, smoother beak surfaces, and a clumsier flight style while wing strength develops. A hand-reared youngster may look fully grown while still depending on its owner for reassurance and routine.
Growth in a timneh is therefore measured in behaviour as much as inches. The juvenile that steps up to anyone becomes the selective adult that chooses one or two people, and the cage and handling plan should anticipate that adult personality rather than the easy baby stage. Buying for the grown bird — its wingspan, its beak strength, its decades of adult life — is the decision that holds up.
Planning Space for the Grown Bird, Not the Baby
Planning space for a grown timneh parrot means budgeting floor area for a wide cage, a play stand, and safe flying room with windows covered or marked while the bird learns the layout. A timneh in full flight is fast and heavy-bodied, and early collisions are a real risk in a new home, so short supervised flights between two stands are a safer start than opening the cage in an unfamiliar room.
It also means thinking about the beak that comes with that body. An adult timneh can splinter soft wood quickly, crack hard nuts, and damage door frames or furniture during out time, so supervised freedom and sacrificial chewing blocks are part of housing an adult of this size. Record the setup that works — cage dimensions, favourite perch heights, flight routines — so anyone helping with the bird copies it exactly. If your timneh ever moves to a new home, KinsLe Transferrable Profiles carries those size and setup details across with the bird.
