Rarely Discussed: What do we actually know about parrot welfare?
We read research about parrots all the time. So when we say that companion-parrot welfare is under-researched, what exactly do we mean? We decided to dig into that question.
In a systematic review published in 2024, researchers searched three major scientific databases for published research that might provide measurable information about the welfare of captive parrots.
They found 1,848 unique records.
That sounds like a lot.
But those 1,848 records were not 1,848 studies that all demonstrated something about parrot welfare. They were the records identified by the search that might be relevant.
After duplicates were removed and the researchers screened the studies against their criteria, 98 studies remained for the review.
And this is where things get interesting.
Of those 98 studies:
48 involved laboratory parrots.
21 involved companion parrots.
10 involved zoo parrots.
The remaining studies involved breeding facilities, rehabilitation centers, shelters, multiple settings, or could not be assigned to a setting.
So yes, there is research on captive parrots.
But the next question is: what kind of research, on which parrots, and measuring what?
Across those 98 studies, researchers identified 1,512 potential welfare outcomes.
Only 572 were both statistically significant and considered feasible enough to potentially be used as welfare indicators.
And when they looked specifically at companion parrots, only 68 of those significant and feasible outcomes—4.49%—came from companion-parrot research.
That does not mean only 4.49% of parrot research is about companion parrots.
It means that, within this particular systematic review of research that could provide usable welfare indicators, companion parrots accounted for a very small proportion of the evidence that met those criteria.
Because we often say “research shows” as though all parrot research can be applied equally to every parrot.
But a study involving a laboratory parrot does not automatically tell us how a parrot living in a home experiences its environment.
A study involving one species does not automatically tell us what happens in another.
And a study measuring cognition, reproduction, disease, or physiology may be fascinating and scientifically valuable without actually answering the question:
“How do we know whether this companion parrot is experiencing good welfare?”
The 2024 review didn't conclude that we know nothing about parrot welfare.
It concluded that the evidence is uneven, concentrated in certain species and settings, and still insufficient to validate many potential welfare indicators for companion parrots.
Since then, researchers have continued working on the problem.
Expert-consensus research has helped identify which welfare indicators may be important and feasible to assess, and that work has contributed to the development of PsittaWel, a welfare assessment tool specifically designed for companion parrots, published in 2026.
And even PsittaWel's researchers identify the need for further research to establish the reliability of the indicators.
In other words, the science is developing.
That matters to us at Papayago Rescue House.
Because sometimes we observe the same thing repeatedly across our population, but discover that there isn't published research directly answering the question.
Does that make our observation scientific proof?
No.
Does it make the observation worthless?
Also no.
It means we have practice-based evidence that needs to be described honestly as such.
We should be able to say:
“We have published research supporting this.”
Or:
“Research from another setting suggests this may be relevant.”
Or:
“We have repeatedly observed this in our own population, but we do not yet have published research establishing it.”
Those are different statements. And knowing the difference is part of being evidence-based.
Maybe the most important lesson isn't that we don't know enough about parrots.
It's that we need to know what kind of evidence we actually have before we decide what it means.
Because good parrot care isn't about pretending we have all the answers.
It's about knowing what we know.
Knowing what we don't know.
And being willing to keep asking better questions. We have so many.
