Direction: Since birds don’t have houses where do they store food? In their throat. Yes, birds have a bulge below their throat called the ‘storage bag.’ Food stays there and can be coughed up for chicks to eat. Amazing isn’t it? Not having teeth is not an obstacle for birds. They have a special grinding organ called a Gizzard. Food is crushed by the muscles as it sloshes around the gizzard. Some birds swallow grit and small stones, these stay in the gizzard and help to grind the food.
