These flamingoes look very different to the usual bright pink that most people are used to seeing but their pink colouring comes from the carotenoid pigment in the shrimp and spirulina that forms the main part of their diet. I can only assume that these salt marshes are lacking in these shrimp to give them their beautiful bright pink plumage.
seen on las salinas in Calpe, spain. a protected area for waterbirds.
mostly Juvenile birds with the exception of one showing a small patch of pink.
