park

Today when I went down to the park for the first time, it was cloudy.
When I was on the breakwater, the water was murky and a greenish color.
While I was on the breakwater, I saw some sea gulls and ducks.
When I was in the park, I saw some sea gulls out on the water.
When I was at the battle site bench, it was high tide with only a small bit of beach.
At the battle site bench, there were a lot of sea gulls on the small bit of beach and in the water. There were also two male erasion wigeons, some ducks, two male pintails, some American wigeons, and some goldeneyes.
I sat on a bench and took some photos of the pintails, wigeons and sea gulls for a bit before getting up and continuing down the trail.
When I was nearing the trail by river, I saw some brown creepers on some trees.
When I was on the trail by the river, I saw one swan and some ducks.
I also heard some chickadees.
When I was on my way back home, it was starting to sprinkle.
Why were there two male erasion wigeons?
When did the other male erasion wigeon get here?
Why was the water a murky greenish color?
