Park

Today when I went down to the park for the first time today, there was even more snow on the ground and it was partly cloudy.
When I was near the house, I saw a bunch of robins in someone’s yard.
When I was nearing the harbor, I heard and eagle and saw a raven flying.
When I was out on the breakwater, I saw some sea gulls and ducks.
When I was almost to the battle site bench, I saw a goose out in the water, and I also 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 trail by the river, I saw some ducks and swans and sea gulls. I also heard a eagle in the trees somewhere.
When I was on the trail by the river, I saw some ducks and mergansers.
When I was on my way back home, I heard a Red winged blackbird near where I saw all the robins when I was on my way to the park, and the robins were still there. I looked for the Red winged blackbird. Once I saw it I took some photos of it until a starling scared it off, I was looking into my camera screen so I didn’t see where it flew.
Why was the goose all on its own?
Why is the Red winged blackbird here?
Why did the starling scare off the Red winged blackbird?
