Aerial photo taken on June 3, 2021 shows herons perching on trees in Lian'ao Village of Bili Town in Luoyuan County, southeast China's Fujian Province. Lian'ao Village is a small village close to the sea and surrounded by hills. From March to April every year, flocks of herons come to the forests near the village to build nests and give birth to chicks, thanks to the protection from local villagers and the good local environment.
