Which bird forms suction with its mouth when drinking?

• A. Blue Jay
• B. Sparrow
• C. Mourning dove
• D. Crow

Answer: (C)

When birds drink, they use different techniques. Some create suction with the mouth and throat, pulling water in like a tiny pump, while others simply lap water with the tongue and bill. The mourning dove is known for this suction method: it forms negative pressure in the mouth and throat to draw water up into the mouth as it swallows. This suction-driven drinking is a characteristic behavior of doves and pigeons, setting it apart from many other birds that drink by dipping and lapping with the tongue. That’s why mourning dove is the best choice here.
