Pinker Flamingos Are More Aggressive Than Pale Flamingos

00:01:37

Did you know that bright pink flamingos are more aggressive than their paler rivals when fighting over food? Pink feathers are a sign of good health in flamingos and a flush of color can also mean they’re ready to breed. Pinker flamingos can be more aggressive when feeding as they’re healthier and have more energy to fight. Colour plays an important role in this. The color comes from carotenoids in their food, which for lesser flamingos is mostly algae that they filter from the water, Dr. Paul Rose, University of Exeter. Dr. Rose studied the birds in different feeding situations and found that captive birds should be feed in a wide space. His study found that foraging doubled when the birds were fed in the outdoor pool and there were little displays of aggression. When the birds were fed indoors from a bowl they spent more time fighting than eating. Dr. Rose believes feeding flamingos in a wide-open space encourages natural foraging and reduces aggression. When keepers changed to this method of feeding the flamingos become more relaxed and had pinker feathers.
