Flamingos are pink because of what they eat, and dolphins enjoy getting high.

Flamingos Are Not Actually Pink

If you have ever visited a zoo, you probably have stark memories of the hot-pink birds that often balance on one leg. Nevertheless, flamingos are naturally grey, and their feathers turn pink because of the shrimp that they eat.

For a long time, flamingos living in zoos were grey, and zookeepers could not figure out why. When scientists realized that the reason was that they were not eating brine shrimp, zookeepers began supplementing the flamingos’ diet so that they would have the brilliant pink feathers that so many of us associate with them.
