Flamingos

The BBC has a great story up now, about a couple of gay male Flamingos acting as surrogate parents to a chick. You can find the story here. Apparently they had been trying to steal other birds eggs to raise, and after seeing a nest abandoned the keepers decided to give them the abandoned egg to raise. In another curious part of the tale it turns out that male Flamingos can also produce milk, from their throats, so they can feed the chick until its beak develops enough for it to filter feed.
