Scientist follow Genetic tagging according to the habitat of animals and their migration pattern which is helpful for siting proper conservation strategies.
Step-by-step explanation:
To go in the field and do random tagging is very laborious and hard work which is bit impossible for zoologist. That's why they follow genetic tagging where they categorized and grouped animals on the basis of their habitat and migration pattern. All the animals and birds are not inherent of its present place. They might come from another places.
In situ and ex situ conservation are two important biological conservation strategies. In first one animals used to be conserved in their native places like national park, sanctuary and in second one animals move to the other sites like zoo, botanical garden etc.
