The flamingo is well-known for its habit of eating with its head upside-down. This behaviour is largely due to the structure of its mouth and the logistics of lowering its long, graceful neck into the water.
The flamingo's oddly shaped bill filters dirt and other inedible objects from food, with the help of hairy projections called mandibles. The flamingo’s tongue helps pump the food-filled water in and out about three or four times a second!
Their diet typically consists of small organisms such as brine shrimp and algae, but this may vary depending on the size and shape of the bill.
