👉 In biology, a "birdmouthed" structure is a type of organ found in birds. It refers to an organ that is typically located at the back of the bird's neck and is often associated with flight or flying. Examples of such organs include the heart, lungs, and beaks (the teeth). These structures are important for providing air and oxygen to the birds' respiratory system, as well as providing food and shelter for them while they are in flight.
