park

Today when I went down to the park, it was mostly cloudy.
when I was still close to home, I saw some juncos and some sort of sparrow in some trees and bushes and on the ground. When I walked by, they flew off.
When I was out on the breakwater, I saw some sea gulls.
When I was in the park, I heard a squirrel somewhere in the forest.
When I was at the battle site bench,it was a little bit windy, and it was high tide. When I was looking out at the water when I was by the battle site bench, I saw two birds far out in the water.
When I was by the trail by the river, I didn’t see any birds out in the water.
When I was on the trail by the river, I saw some ducks and two swans on the other side of the river by some grass that was still above the water.
When I was on my way back home, I was walking on the other side of the road from the beach and I heard some people by the water. I also saw that the house that some people had been building looked close to done.
Why were they building the house?
Why were most of the ducks by the grass?
What birds were out in the water?
