Drones are used in wildlife rescue for several purposes, including:

1. Search and rescue: Drones equipped with cameras and thermal imaging sensors can be used to search for injured or trapped wildlife in hard-to-reach areas, such as forests, mountains, and wetlands.
2. Monitoring and tracking: Drones can be used to monitor and track wildlife populations, helping conservationists to better understand their behavior and habitat.
3. Animal population counting: Drones can be used to count wildlife populations, providing a more accurate picture of their numbers and helping to track trends in wildlife populations over time.
4. Poaching detection: Drones equipped with cameras and infrared sensors can be used to detect and deter poachers, who often target endangered species.
5. Habitat protection: Drones can be used to monitor wildlife habitats and track changes in land use, providing early warnings of potential threats to wildlife populations.

These are some examples of how drones are being used in wildlife rescue to help conserve endangered species, protect habitats, and support conservation efforts.
