Here is a gay flamingo couple that adopted a baby flamingo that had been deserted by its birth mother (or is it "hatch mother"?).
Carlos & Fermando with their new bundle of love
According to the Daily Mail,
When a newly-hatched flamingo chick was abandoned by its mother and father, the search for surrogate parents did not take long.
Carlos and Fernando, the only gays in the bird sanctuary, were the automatic choice.
They'd apparently been trying to steal babies before they became legal adoptive parents. They even had a rebirthing to strengthen their bond.
They just stuffed the little baby bird back in an egg, taped it up, and made him peck his way out all over again.
