Animal identification using a means of marking is a process done to identify and track specific animals. It is done for a variety of reasons including verification of ownership, biosecurity control, and tracking for research or agricultural purposes.
Animals tend to incorporate several types of navigation techniques, like magnetic orientation and landmarks, to their repertoire in order to perform normal navigation or to migrate. When animals use the sun for compass orientation, they must compensate for the apparent movement of the sun with the help of their internal clock .
Animal navigation is the ability of many animals to find their way accurately without maps or instruments. Birds such as the Arctic tern, insects such as the monarch butterfly and fish such as the salmon regularly migrate thousands of miles to and from their breeding grounds, [1] and many other species navigate effectively over shorter distances.

Among them is the family Cathartidae (New World vultures) which the American Ornithological Society (AOS), the Clements taxonomy, and BirdLife International's Handbook of the Birds of the World place in its own order, Cathartiformes.
In sanguineous animals this is the region about the heart; for all sanguineous animals possess a heart, and both movement and the dominant sense-perception originate there. As for movement, it is clear that breathing and in general the process of cooling takes its rise here, and that nature has supplied both breathing and the power of cooling ...
Animals may be fixed in place, allowing them to move while remaining stationary relative to their environment. Tethered animals can be lowered onto a treadmill to study walking, [36] suspended in air to study flight, [39] or submersed in water to study swimming. [40] A fruit fly, Drosophila melanogaster, tethered and walking on a spherical ...
