I just read today that the population of Rose-Ringed Parakeets on the small island of Kauai appears to have doubled in less than a decade! What has gone wrong for humans has gone right for the birds? The humans though are losing income for themselves and products for their communities and beyond. The birds have a thriving flock.
What I humbly suggest is a capture program and sponsor big cages(aviaries) of small populations of the birds throughout the U.S. and perhaps other countries. These cages could be at places in public such as parks and zoos, even potentially at large shopping centers, big offices buildings too? Perhaps if done correctly, they can be used as part of an education program that talks about wild birds, farming, humanity’s responsibilities, being a pet owner and more. Maybe the youngest of birds can be domesticated and sold to private owners to help sponsor them all?
Are they good pets? Looks like if you spend enough time and attention with them. More information on Spruce Pets website Indian Ringneck Parakeet (Rose-Ringed Parakeet): Bird Species Profile (thesprucepets.com)
If you are daring group, you could even sponsor a small sized aviary at a local school, college, hospital with these birds. Perhaps hire junior zoo keepers, youth zoologists to care for them?
