park

Today when I went down to the park for the first time today, there was a lot of snow on the ground.
When I was out on the breakwater, I saw some ducks and crows and a sea gull on a post. I also saw a eagle in a tree.
When I was in the park, I saw a merganser and some ducks out in the water.
When I was nearing the battle site bench, I saw some kinglets and a varied thrush.
When I was at the battle site bench, it was low tide, and I saw some crows out on the beach and a goose fly by. I also saw a heart drawn into the snow on a sign by the bench.
When I was on the trail by the trail by the river, I saw one goose, some swans, crows and ducks. I also saw two geese fly by towards the river.
When I was on the trail by the river, I saw two geese, some ducks, and a gadwall.
When I was on my way back home, I saw a great blue heron out on a post.
Who made the heart?
Was one of the two geese flying towards the river, the one I saw at the battle site bench?
why were there only crows out on the beach?
