A pair of gay flamingos have adopted an abandoned chick, becoming parents after being together for six years, a British conservation organisation said Monday

Carlos and Fernando had been desperate to start a family, even chasing other flamingos from their nests to take over their eggs at the Wildfowl and Wetlands Trust (WWT) in Slimbridge near Bristol.

But their egg-sitting prowess made them the top choice for taking an unhatched egg under their wings when one of the Greater Flamingo nests was abandoned.

The couple, together for six years, can feed chicks by producing milk in their throats.

"They were rather good at sitting on eggs and hatching them so last week, when a nest was abandoned, it seemed like a good idea to make them surrogate parents."

Gay flamingos are not uncommon, she added.
