park

Today when I went down to the park, it was raining a little bit. When I was out on the breakwater, it was low tide, and I saw some seagulls, harlequins, ducks, goldeneyes, crows, ravens, and a merganser. When I was nearing the park, I saw that someone had moved the bucket from where I put it on the log, to on the metal bench by the side walk. When I was at the battle site bench, I sat on the bench and watched the seagulls and eagles. When I was watching a eagle flew by a couple of times scaring most if not all of the seagulls. When I was on the trail by the river, I saw some seagulls and ducks. When I was nearing the foot bridge, I saw a squirrel on a dead tree. It ran farther back into the forest after I saw it. When I was on my way back home, dad came down to road in the car and told me I had to come with him to look at a kingbird.
Why had someone moved to bucket to the bench?
Why was there only one merganser by the breakwater?
Why are there always seagulls by or on the river?
