Breeding hybrids good or bad ?

I have been reading over the last couple of days a debate of sorts taking place on the emotive subject of breeding hybrids (crossed parrot close related species). In the case in question it was a Macaw hybrid which are often the most popular ones bred. However there are sometimes cockatoo or Amazon parrot hybrids bred. And sometimes this is done intentially in order to breed a more unusual parrot variety and sometimes it just is a case of a person producing a hybrid as a result of difficulty in finding pure species of the same type.

In America, hybrid Macaws are quite sort after and do generate a demand for them which generates quite high values. In Europe there seems to be less demand for them although on the otherhand perhaps they have not been purposely bred here quite so much.

Some people are vermently again such crossing of these parrots as it appears to be medddling with nature, but on the otherhand there is much evidence of crossing of similar species in nature anyway (although this is evolution over a long period).

I breed Caiques as my particular interest  and certainly there is evidence that the separate suspecies (of which there are 5) have evolved by hybridisation of perhaps only 2 original species. I have seen Black -headed caiques (from the wild) with some green thigh feathers and Yellow Thighed caiques with green thigh feathers and even Yellow Thighed Caiques with Yellow Tailed feathers. Naturally some of the territories of these parrots overlap which must give rise to hybridisation.

I also have a pet Caique which was crossed from a Green Thigh and Yellow Thighed breeding pair, as at the time I could not find a suitable mate for a Green Thighed cock Caique which I had so I mated him with a Yellow Thighed hen and the same year they had babies which were hybrids. These of course are not particularly sort after so don't have a high value but I can see how sometimes breeding hybrids can be incidental to keeping parrots rather than as an intentional outcome.

But of course some hybrids are bred quite intentional to generate a high value in much the same way as mutation coloured parrots are. My personal view is that keeping parrots in captivity is of course not the same as parrots living in the wild. Most private breeders are keeping them in collections because of their scarcity and value, so breeding hybrids and mutations is just another extension of the hobby. Certainly these parrots should not be introduced to wild populations, but in truth they would not survive in the wild if someone tried to do it. And my opinion is that the number of hybrids that are bred in comparison with the number of natural parrots do not really effect the balance of nature.
