In the South China Sea, islands and reefs have evolved into avian sanctuaries owing to their distinctive climate, attracting a plethora of bird species. Local rangers dedicate themselves to safeguarding the natural habitats of these indigenous birds.

China's extensive maritime expanse hosts 78 documented species of seabirds. Numerous species, such as terns, thrive in the urban landscape of Sansha, South China's Hainan province.

Volunteer reef guards in the city have taken up the mantle of protecting terns in the region, demonstrating their commitment by conducting weekly clean-up operations to rid the seas of debris. This proactive measure aims to mitigate the risk of birds ingesting harmful materials or getting entangled in fishing nets.

During their regular patrols, the volunteers maintain a respectful distance while observing the seabirds, ensuring minimal disruption to their natural habitat. Their approach prioritizes reducing direct contact, affording the terns the space needed to settle and thrive undisturbed.
