park

Today when I went down to the park, it was sunny. When I was on the breakwater I saw some seagulls. When I was by the battle site bench, I heard and saw some Black oystercatchers out on the beach by the water along with some seagull. When I was at the battle site bench, I could still see the black oystercatchers and the seagulls out on the beach. The tide wasn’t to high. When I was by the trail by the river, I saw some seagulls. When I was on the trail by the river, I saw some more seagulls, some ducks and the two swans on the other side of the river. I saw two ducks and a wigeon on the side of the river I was walking on, and they flew to the other side of the river when they saw me. While I was still walking on the trail by the river, a male bufflehead flew up the river and landed. When I was on my way back home, I saw some common mergansers and two red breasted mergansers one male and one female all by sage rock.
Why have the two swans stayed at the park?
Why was it sunny today?
Why was a wigeon with two ducks?
