视频展示了一群鹈鹕在水中活动的场景。这些鹈鹕有着白色的羽毛和黄色的长喙，它们密集地聚集在一起，有的在水中游动，有的则在梳理羽毛或休息。水面呈现出深棕色，可能是由于泥沙或其他物质的影响。鹈鹕们显得非常活跃，不断移动位置，整个画面充满了生机与活力。
The video shows a large flock of pelicans gathered in a body of water. The pelicans are mostly white with long, yellow beaks and are seen swimming and standing in the shallow water. Some of the pelicans are preening their feathers, while others are simply floating or moving slowly through the water. The scene is calm and serene, with the pelicans densely packed together, creating a visually striking pattern across the water's surface. The water appears to be a muddy brown color, suggesting it might be a river or a lake with sediment-rich water.
A large group of white pelicans with yellow beaks are floating on a brown water surface. The pelicans are initially stationary, but gradually, some of them begin to move their heads and bodies. More pelicans start to rise from the water, lifting their heads and bodies higher. The movement becomes more pronounced as more pelicans continue to stand up, creating a dynamic scene. The pelicans that were initially stationary are now mostly standing up, with their heads and necks extended. The scene shows a mix of pelicans both standing and still floating, with the standing ones appearing more alert.
