这段视频展示了一群天鹅在绿色的水面上游动的场景。天鹅们有的在水面悠闲地漂浮，有的则将头和脖子伸入水中觅食。它们的羽毛洁白无瑕，与深绿色的水面形成了鲜明的对比。画面中可以看到多只天鹅，它们分散在不同的位置，有的成对出现，有的则独自行动。整个场景显得非常宁静和谐，给人一种自然美的享受。
The video shows a group of white swans swimming in a greenish body of water. Some swans are gracefully gliding on the surface, while others have their heads submerged, likely feeding. The water is calm with gentle ripples, and the scene conveys a serene and peaceful atmosphere. The swans' elegant movements and the vibrant color of the water create a visually appealing contrast.
A group of swans is floating on a green lake, with some swans dipping their heads into the water to forage. One swan in the center lifts its head from the water and begins to swim forward. This swan then lowers its head again to continue foraging.
