Captive parrot welfare: what an expert consensus ranks at the top of the list
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
With so much advice out there on how to set up a parrot's space, it's hard to know what actually weighs on its welfare and what's a minor detail. A study published in late 2024 asked international experts directly, using a rigorous consensus method. Our setup guidance is gathered in the bird bedding and habitat category.

How did this study build its ranking?
A study by Chalmers, Cooper and Ventura, published in 2024 in the journal Animal Welfare, followed a modified Delphi method: 26 experts and sector professionals first rated a list of welfare issues by severity, duration and prevalence; 14 participants then agreed or disagreed with that ranking in a second round; finally, 7 participants refined the hierarchy through discussion workshops, reaching 86% consensus (6 of 7 experts agreeing with the final ranking).
What tops this ranking?
The issues judged highest priority, in order, were lack of owner knowledge and support, social isolation, then housing, followed by the opportunity to express natural behaviors, nutrition, normal behavioral development in young birds, the absence of a long-term life plan, abnormal behaviors, the lack of bird-specific veterinary training, and finally insufficient enforcement of regulation.
What this study does not show
A priority ranking is not a direct measurement of any individual bird's welfare: it reflects expert opinion on the potential severity of each issue, not an assessment of specific animals. The Delphi method aims for consensus, which can smooth over genuine disagreement between specialists with different approaches. The expert sample stays small (7 participants in the final round), even though the method is well recognized for this kind of question when no large-scale statistical data exists.
What this means for setting up a parrot's space
- Housing ranks right after social isolation in this list: a well-suited cage doesn't make up for a bird left to itself, but it remains a top-priority lever once human presence is already covered.
- Check placement as much as size: these two factors are often treated separately even though they fall under the same top-ranked issue, detailed in our guide to cage placement: mistakes to avoid.
- Compare a cage against an aviary based on the space actually available rather than price alone, a trade-off covered in our guide to cage or aviary, which to choose.
Frequently asked questions
Why does owner knowledge rank above housing?
Because an otherwise adequate setup stays ineffective if the owner doesn't know how to use or adapt it to their bird's real needs, per the reasoning of the experts consulted.
Is nutrition really ranked below housing in this consensus?
Yes in this ranking, but the gap between the two stays narrow: the experts place both among the top-priority issues, well ahead of the bottom of the list.
Does this ranking hold for every parrot species?
The study reasons at the level of the captive parrot in general, without breaking down a species-specific hierarchy. Find all our guides in the bird hub.
