Light blue flamingo1/23/2024 Their diet is rich in red pigments including astaxanthin, phoenicopterxanthin, and phoenicophorbium from algae and shrimp. The most brilliant red feathers occur in Chilean flamingos. Key carotenoids that determine flamingo colors Carotenoid The specific types and ratios of carotenoids influence the resulting color. When flamingos eat these carotenoid-containing foods, the pigments are partially broken down in the liver and deposited into the birds’ feathers, beak, and legs. Zeaxanthin – Yellow pigment in many plant/algae sources.Lutein – Yellow pigment found in plants and algae. Phoenicophorbium – Red alkaloid unique to brine shrimp.Phoenicopterxanthin – Red pigment unique to halophilic algae.Canthaxanthin – Orange/pink pigment from algae.Beta-carotene – Red/orange pigment in algae and brine shrimp.The most common carotenoids ingested by flamingos include: Over 600 carotenoids exist, but only about 50 are found in typical flamingo foods. Since animals cannot synthesize carotenoids on their own, they must obtain these pigments from food sources. Carotenoids are organic compounds produced by plants and algae. Mate rituals include posturing displaysįlamingos acquire their vibrant colors from carotenoid pigments in their diet.Other carotenoids create pink, orange, yellow.Large flocks at saline and alkaline lakes.To understand flamingo colors, we first need to know some fast facts about these funky-looking birds: Taxonomy Let’s explore why blue would be an anomaly in the flamingo world! Fascinating Flamingo Facts While wild flamingos span the pink and orange color spectrum, no natural flamingos exhibit blue hues.
