park

Today when I went down to the park, it was sunny and cold.
When I was walking towards the breakwater by the harbor, I noticed that some trees were missing by the side of the trail. There were wood chips where they had been, I guess they go cut down.
When I was on the breakwater, I saw some ducks and sea gulls out in the water.
When I was in the park, I saw some varied thrushes by the trail.
When I was near the battle site bench, I sat down on a bench by the beach that was there for a bit before getting back up and walking some more.
When I was close to the battle site bench, I saw a squirrel in a tree.
When I was at the battle site bench, it was low tide, and I saw a few sea gulls out on the beach.
When I was by the trail by the river, I saw some sea gulls and crows out on the beach.
When I was on the trail by the river, I saw some wigeons and ducks by the grass on the other side of the river. I also saw seven swans by the trail on the other side of the river.
Why were there seven swans there today?
Why did they cut down the trees?
Why did they put wood chips were the trees had been?
