Did you see two Black-bellied Tern chicks?
Black-bellied Tern (Sterna acuticauda) chicks, found in South and Southeast Asia, have downy feathers for camouflage. They nest on sandy or gravelly riverbanks, with parents feeding and protecting them. Chicks grow quickly, fledging in a few weeks. They rely on healthy river ecosystems, making them vulnerable to habitat disturbances.
