 Dear students, in this topic we shall discuss the animal navigation and migration behaviors. Migration is a regular long distance change in location which involves navigation or traveling over long distances. During this migration, animals travel through many unfamiliar territories and environments which they have not previously encountered. Dear students, the stimuli for migration include seasonal droughts, harsh weather conditions, hot summers, or cold winters. Different animals in the stimuli area have long distance migration. The migratory behaviors are observed in a wide variety of birds, fishes, butterflies, gray whales, and many other animals. The navigational abilities of the animals rely on several sensory cues or signals which guide them in orientation and finding their path or way. Some types of cues used by animals are not perceivable by human beings. These types of cues, which are used by animals, include sun compass, celestial cues, arts magnetic field, visual auditory, and alfactory cues for migration and navigation. We shall discuss all these cues one by one. First of all, let's talk about sun compass. Sun compass is used to track the position of an animal relative to the position of sun on the sky. The sun's relative position changes during the day. Animals adjust for these changes through a circadian clock. The circadian clock is an internal mechanism that maintains a 24-hour active-rhythmic cycle. But animals understand the sun's movement in this way. The nocturnal navigators cannot use sun compass, rather they use celestial cues. These celestial cues have stars, moon, etc. One of the most important celestial cues that animals use is the North Star, which has a constant position in the night sky. Some long-distance migrants have magnetic sense, so they navigate by sensing the position relative to the arts magnetic field. Many birds also use visual auditory and alfactory cues to find their path to their destination where they migrate. These visual cues have certain landmarks, as well as a plane of polarized light in the visual cue. Other than this, there are certain types of sounds in the auditory cues and certain types of orders are used as alfactory cues.
