Today when I went down to the park for the second time today, it was mostly cloudy. When I was out on the breakwater, I saw some seagulls and ducks out on the water. I also saw a song sparrow on the beach. When I was in the park, I saw some goldeneyes and other birds out on the water. When I was at the battle site bench, it was low tide and I saw an eagle out on the beach by the water and I saw some crows and seagulls out on the beach too. When I was by the trail by the river, I saw some seagulls out on the water. When I was on the trail by the river, I saw three ducks on the water on the other side of the river, and I saw a winter wren in the bushes and saw squirrel in the trees. When I was coming off the trail by the river, I heard some sort of bird in the trees. When I was on my way out of the park, I saw a varied thrush on a rock, that flew away when it saw me. When I was on my way back home, I could see some of the sun set.
What was the bird I heard?
What was the song sparrow doing on the beach?
Why were not many ducks?
