Krista Menzel's letter is a fine example of yet another in an endless string of attempts by "animal welfare" organizations to make the victims responsible for acts perpetuated against them.
Menzel failed to mention in her letter that there are hundreds of thousands of parrots who enjoy happy lives in captivity. What seems to be the determining factor for captive parrots is not so much their nature but the unwillingness of some owners to fully understand the nature of the obligation they assume when they decide to add a parrot to their home environment.

When I discovered an almost complete lack of information in the scientific literature about the parrot genus I keep (Pionus parrots), I founded a nonprofit organization to conduct joint scientific/avicultural research of the genus in its natural habitats in South America.

Partly as a result of our work, Pionus parrots are seldom, if ever, seen inhabiting rescue facilities. Animal rights enthusiasts fail to realize that wild parrots in natural habitats frequently choose to associate with humans; the species are not as incompatible as the term "wild" implies.
