park

Today when I went down to th park for the second time, it was sort of sunny.
When I was on the breakwater, I saw some sea gulls and ducks.
When I was in the park, I heard a squirrel.
When I was nearing the battle site bench, I saw that the ground was wet on the trail underneath some tree branches and I heard a sort of buzzing noise up ahead.
When I was at the battle site bench, it was low tide and there were a lot of sea gulls out on the beach.
Some park rangers were cleaning the sign and trash can at the battle site bench.
When I was nearing the trail by the river, I saw a lot of sea gulls and one duck.
When I was on the trail by the river, I saw one swan, some mergansers and a few ducks on the other side of the river.
I also heard some chickadees and I saw either a downy or a harry woodpecker on a tree.
When I was on my way back home, I saw some ducks on sage rock and some more sea gulls.
Was it a harry woodpecker or a downy?
Why were there only a few ducks on the river?
Why were they cleaning the sign and the trash can by the battle site bench today?
