A same-sex flamingo couple at an English zoo has welcomed a fluffy new family member.

Curtis and Arthur, two male Chilean flamingos at Paignton Zoo in Devon, are the zoos first same-sex pair to successfully hatch and raise a chick together, the organization announced Monday on social media .

Zoo staff members arent entirely sure how the two got their egg, but the most likely scenario is that the egg was abandoned by another couple and then adopted by Curtis and Arthur, bird curator Pete Smallbones said in a news release .
