Five Bonaparte's gulls hovering over and diving into water. Three of them are hovering over the water at the left, near the center, and at the right. There is one with its head in the water and another one just splashing into the water at the bottom. The gulls are mostly white with jet black heads, black tips on the wings, and orange legs. The one on the far left also has grey on its uplifted wing.
