Another species that is critically endadgered in the wild but rather common in private care is swifts parrot.

Personally, I think that some very popular pet species that are now threatened by illegal capture for pet sale could profit from special breeding centers (in zoos?) that would produce thousands of youngsters and so cover demand and decrease the market price to the point that illegal collection and distribution would just become not viable anymore.
The most prominent species I can think of is Radiated tortoise. It breaks my heart seeing thousands of confiscated animals when we already know enough about its husbandry and breeding and some private people as well as zoos breed them. Just not in high enough numbers. Why not to take the confiscated animals, put them into adequate pens and let them breed to the maximum possible biological rate, incubate all eggs and keep babies in optimum condition so as much of tehm as possible survive and can be sold.
Or the most popular singing birds in SE Asia. Bali mynah is just one of many. Create farms and produce thousands. And illegal capture should slowly dissappear.
Some species with slow reproduction (like Spider tortoises) or difficult requirements (European eels) are not suited for such scenario. Many many others are.

This leads me also to a conflict between heart and head.
Years back, when I have seen horrible conditions under which local Czechs animal traders kept small parrots bought from small Czech private breeders and intended for export to mainly Middle East, I was disgusted and would fight to stop it. But over time, I slowly realised how huge and hungry is the market for pets in quickly growing countries in many parts of S/E Europe and especially Asia is, and I ve come to more pragmatic worldview. Maybe the suffering of those individual parrots, bred for many generations in captivity and to a degree domesticated, more in line with domestic animals like cows or chicken, is maybe a price needed to pay to feed the thirst of pet market. And so replace birds that would be otherwise harvested from wild.
