park

Today when I went down to the park for the first time today, it was cloudy and the ground was a little bit wet.
When I was walking to the park, there were a lot of worms on the sidewalk. I picked a couple of the worms of the side walk and put them in the grass.
When I was on the breakwater, I saw some sea gulls, ducks, a kingfisher and a great blue heron. The great blue heron was on a pole.
When I was in the park, I saw some ducks, sea gulls and buffleheads out in the water.
When I was at the battle site bench, it was low tide, I saw some sea gulls out on the beach by the water.
When I was near the trail by the river, I heard some kinglets, and I saw some sea gulls, ducks, an eagle by the water and two geese.
When I was on the trail by the river, I saw some ducks on the other side of the river. I also saw two geese out by the grass on the other side of the river.
Where the two geese I saw by the grass the same geese as the two geese I saw when I was near the trail by the river?
Why were there so many worms on the side walk?
What was the eagle doing by the water?
