park

Today when I went down to the park, it was cloudy and a thin layer of snow coated the ground.
When I was out on the breakwater, I saw some seagulls.
When I was in the park, I saw some sea gulls and ducks out in the water.
When I was nearing the battle site bench, I saw some sea gulls and a great blue heron in shallow water.
When I was at the battle site bench, it was low tide, and I saw some sea gulls out by the edge of the water and a great blue heron. I think the great blue heron was the same one I saw earlier.
When I was by the trail by the river, I saw some crows out on the beach along with a great blue heron. I also saw two swans at the end of the river and two eagles out on a branch that was in the water.
When I was near the trail by the river, I saw some sort of spine bone on the trail.
When I was on the trail by the river, I didn’t see anything.
Why did it snow this morning?
Why were there ducks out by the beginning of the park but not in the river?
how did the bone get there?
