视频中展示了一只黑色的天鹅在水中梳理羽毛。天鹅的身体大部分浸在水中，只有头部和背部露出水面。它的羽毛呈现出深黑色，显得非常光滑和有光泽。天鹅的脖子弯曲，用喙轻轻梳理着自己的羽毛，动作优雅而缓慢。水面上泛起一圈圈涟漪，反射出周围的光线，显得格外宁静和美丽。背景是绿色的水面，给人一种清新自然的感觉。
The video shows a black swan floating on a greenish body of water. The swan is grooming itself, bending its neck to reach its back and preen its feathers. The water around the swan has ripples, indicating movement. The lighting suggests it might be early morning or late afternoon, as there is a warm, golden hue reflecting on the water's surface. The scene is calm and serene, with the swan being the main focus.
A black swan is floating on a greenish water surface, gradually turning its head to the back and tucking it under its wing. The scene then transitions to a bird standing on the ground, with the previous image of the swan still faintly visible in the background.
