park

Today when I went down to the park for the second time, it was cloudy and there was a tiny bit of rain.
When I was out on the breakwater, I saw an eagle.
When I was in the park, I saw a squirrel on a tree root, when I walked by it ran up the tree. I also saw some buffleheads and a goldeneye out in the water.
When I was at the battle site bench, the tide was out a little ways, and I saw some ducks and harlequins out in the water. I also saw a bunch of crows out by the water on the beach.
When I was on the trail by the river, I saw an Eurasian wigeon and some ducks on the rocks on the other side of the river. I also saw a merganser in the water by the side of the river I was walking on.
When I was on my way back home by sage beach, I saw three sea gulls in the water by the beach along with some ducks.
Why were there only sea gulls at sage beach?
Why is the Eurasian wigeon here?
Why were the crows out on the beach?
