What is marking animals?

Marking animals is a technique used by scientists, researchers or wildlife conservationists to track and monitor animal populations and movements. There are many ways to mark animals, including tags, collars, ear notches, tattoos, radio transmitters, GPS and satellite trackers, and more. Each of these methods has its advantages and disadvantages, depending on the species and the research question. For example, ear tags are commonly used for identifying cattle, while GPS collars are more suitable for tracking large mammals like elephants and lions. Marking animals can help answer scientific questions related to animal behavior, demographics, migration patterns, range and habitat use, and can inform conservation efforts. In addition to scientific research, marking animals can also aid in wildlife management and control, such as hunting or pest control. However, it's important to note that marking animals can be invasive and stressful to the animals, and it should be done with care and respect for the animal's welfare.
