Have a look at this article.
Among the responses there is this... "Problem is the species are not a native bird. because of that, diseases from these birds can and will effect our native bird populations. I understand the whole save the parrot movement. I know Parrot lives Matter. We have to protect all our native species of bird and allowing a non native bird species into the foreign environment is a mistake. What is so nice since there is no hunting regulations on non native birds I can and will hunt these birds down and kill them kill them all"
Does this guy have a point or no?
Is it climate change maybe eg. South Texas becoming tropical?
