park

Today when I went down to the park it was cloudy and cold and there was also a bit of snow falling.
When I was on the breakwater, I saw some sea gulls, ducks and three eagles.
When I was in the park, I saw some varied thrushes in the bushes.
When I was at the battle site bench, it was almost high tide and I saw some sea gulls.
When I was on the trail by the river, I saw some ducks, nine swans, mergansers, some ravens flying, an otter, geese and a erasion wigeon.
Two of the swans were father up the river and the mergansers were by them.
The geese were on the grass by the other swans and the ducks and erasion wigeon on the other side of the river.
The otter was on the side of the river I was on. I saw it dive into the water from the rocks, and I could see it swimming underwater.
When it got to where I couldn’t see it underwater, I could see where it was going by the bubbles it made.
When I was near the end of the park, I saw a squirrel run across the trail.
when I was on my way back home, I saw some crows across the road in the grass and on a fence.
Why did the otter make bubbles?
Why were the geese there?
Why were two of the swans farther up the river?
