Carlos and Fernando are male flamingos at the Slimbridge wildfowl reserve in Gloucestershire. They’re inseperable, performing mating dances every year and raising chicks.
“They have been known to fight the heterosexual birds and steal their eggs. There is usually a ‘handbags-at-10 yards’ moment where they scrap with the couple before stealing the egg.
“They are very good parents though and behave just as the heterosexual birds do when rearing their young.”
