park

Today when I went down to the park for the second time, it was still cloudy and raining a little bit.
When I was out on the breakwater, I saw a couple of sea gulls and a eagle on the poles.
When I was in the park at one of the opening areas, I could see some of the sun through a small hole in the clouds as it was setting.
When I was at the battle site bench, I saw some sea gulls out on the beach, and I also saw raven land by some seaweed near me.
When I was near the trail by the river, I saw some more sea gulls and a few ducks.
When I was on the trail by the river, I saw a bunch of mergansers and ducks near the grass on the other side of the river.
When I was at the end of the trail by the river, I heard a Pacific Wren somewhere in the bushes.
When I was on my way back, it was sill raining, but it was still fairly light out.
Why did the raven land by the seaweed?
Why do the sea gulls and eagles perch on those poles?
Why were there a bunch of mergansers on the other side of the river?
