7月30日，在肯尼亞馬賽馬拉國家保護區(qū)，成群的角馬聚集在馬拉河邊準備渡河。每年7月起，數以百萬計的角馬、斑馬等野生動物為追逐水源和青草，從坦桑尼亞塞倫蓋蒂國家公園向北遷徙至肯尼亞馬賽馬拉國家保護區(qū)，途中跨越國境與河流，形成了一條震撼人心的“生命之河”，是東非大草原上的一大自然奇觀。[新華社記者 韓旭 攝]

Herds of wildebeests gather and rest by the Mara River, preparing to cross, in the Masai Mara National Reserve in Kenya, on July 30, 2025. Starting in July each year, large herds of animals such as wildebeests and zebras migrate from Tanzania's Serengeti National Park to Kenya's Masai Mara National Reserve, forming a spectacular "river of life" across the savannahs and rivers.
