park

Today when I went down to the park for the second time, it was sunny and there were a few clouds and it was a bit breezy.
When I was out on the breakwater, I saw some sea gulls and ducks.
When I was at the battle site bench, it was low tide and I saw some sea gulls.
When I was on the trail by the clearing, I saw one of the small vehicles the park uses off to the side of the trail and some people were putting some salmon berry bushes into the thing that was attached to the back of it.
When I was near the trail by the river, I saw some sea gulls and ducks.
When I was on the trail by the river, I saw one swan and two ducks. The swan was by the rocks on the side of the river I was on, but moved away when I walked by.
When I was nearing the end of the park, I heard some chickadees and kinglets up in the trees.
When I was on my way back home not too far from the end of the park trail, I saw two red breasted sapsuckers on a telephone pole. One was up higher near the top, and the other was down lower and was pecking on something that wasn’t wood. It was pretty loud.
Why were are they trimming the stuff back there?
Why was the swan on the side of the river I was on?
Why was the sapsucker pecking on something that wasn’t wood?
