park

Today when I went down to the park for the second time, it was cloudy and there was a little bit of rain.
When I was out on the break water, there were a bunch of sea gulls flying around and out on the water. While I was still out on the breakwater, I saw a few cormorants, and there was a group of sea lions out in the water.
When I was in the park, I heard some chickadees in the trees.
When I was at the battle site bench, it was high tide and I saw some sea gulls and a large group of birds out in the water.
when I was nearing the trail by the river, I saw some goldeneyes and buffleheads.
When I was on the trail by the river, I saw some mergansers and some more buffleheads.
When I was on my way back home and was on the side walk by sage beach, I saw some ducks by some rocks by the shore, and the sea gulls were still there.
Were the sea lions and sea gulls there because there were herring there?
Why were the ducks by the rocks?
Were there herring there?
