unnatural?

Here’s one in the eye for those people who say gay couples adopting is “unnatural”.

A pair of flamingos in Britain, who happen to be a gay male couple, have just become surrogate parents for an abandoned egg. Apparently, gay flamingos are not uncommon, and this couple has a well-known affection for stealing other flamingos’ eggs to raise. See more about this pink couple (pun intended) here.

If it happens in nature, who are we to call it unnatural?
