park

Today when I went down to the park for the second time today, the sun was setting. When I was out on the breakwater, I saw some ducks and sea gulls. When I was by sage beach, I saw a great blue heron out in the water. When I was nearing the park, I saw a varied thrush in the bushes that flew a small distance away when it saw me. When I was in the park, I heard a squirrel alarm somewhere in the trees in the park. When I was nearing the battle site bench, I heard an eagle. When I was at the battle site bench, it was low tide. When I was on the trail by the trail by the river, I saw some sea gulls out in the water. When I was on the trail by the river, I didn’t see any ducks. When I was on my way back home by sage beach, I saw an eagle out by the water on the beach and the sun had almost set.
Why was the eagle out on the beach?
Why didn’t I see any ducks when I was on the trail by the river?
What was the squirrel alarming about?
