Two Male Flamingos Successfully Hatch Egg as Foster Parents at San Diego Zoo

The lesser flamingos, both in their 40s, have been alternating brooding duties and feeding their chick crop milk.

The two male lesser flamingos were given a real egg after successfully caring for a fake one earlier this year.
The chick, born late last month, is thriving under the care of its foster dads.
Flamingo chicks are initially fed crop milk from their parents' upper digestive tract, a process that can temporarily drain the color from the parents' feathers.
The foster fathers have been alternating brooding responsibilities and ensuring the chick is well-fed.
Same-sex bird parenting has been observed in various species, including flamingos, penguins, and vultures.
