Revised Answer (140 words):

The lecture discusses how animals navigate long distances for various reasons, such as breeding or finding food, using different methods like sight and smell. The first example involves mallard ducks, which navigate by observing their surroundings, especially the stars in the sky. These ducks travel at night and rely on star patterns to determine their location and guide their direction as they migrate south during colder weather. The second example is salmon, a type of fish that lays eggs in freshwater streams. Each stream has its own specific smell due to chemicals released by soil and plants. Salmon use their sense of smell to detect these unique chemical cues from the water, which help them locate the exact stream where they were born. By following this distinct scent, salmon are able to return to their birthplace and lay their eggs, ensuring the continuation of their species.
