Ducks display a significant capacity for learning and memory, as evidenced by their nesting habits and ability to track food sources over long distances during migration.Ducks have an excellent sense of smell, being able to detect food from up to 4 miles away and recognize up to 20 different odors.Ducks do have a septum, a divided wall in the nasal passage behind the nostrils and between the two nasal chambers.
The duck’s ‘nose’ is referred to as a bill, made up of bones called coronals and covered in hard keratin and small feathers.Ducks can hold their breath for about 8 to 10 minutes, during which their blood circulates back to the heart and enters body tissues, effectively creating a ‘gill-like’ system that allows them to breathe through their bills.A special valve in the nostrils prevents water entry when the duck dives, protecting the nasal passage.Ducks possess two nostrils on the top of their bills that stay moist, aiding their ability to smell underwater and identify food.They are capable of closing their nostrils when they dive underwater to prevent water from entering. Ducks have an excellent sense of smell, which they use to locate food and sense danger.
These are located on their beaks, and they allow ducks to breathe. Ducks don’t have noses in the way humans do, but they do have nostrils, also known as nares.
