The video shows two black-headed gulls swimming in a calm body of water, likely a lake. The gulls are predominantly white with black heads and black wingtips. They are floating on the water's surface, creating small ripples as they move. In the background, across the water, a treeline is visible, with buildings interspersed among the trees. The sky is overcast, and the overall light is soft and diffused, creating a slightly greyish tone in the video. Bird calls can be heard in the background.
