park

Today when I went down to the park, it was raining a little bit, but it was fairly warm.
When I was not far from home, I saw some juncos and sparrows.
When I was nearing the breakwater, I saw a bunch of crows across the road in a field When I was out on the breakwater, I saw some sea gulls and goldeneyes.
When I was at the battle site bench, it was high tide, and I saw one duck out in the water.
When I was near the trail by the river, I saw some sea gulls out in the water.
When I was on the trail by the river, I saw two swans and a bunch of ducks in the visible grass on the other side of the river. I also saw three Goldeneyes, one male and two females in the middle of the river.
When I was on my way back home, I saw a bunch of juncos, a couple of sparrows on the ground and in the bushes in the same area where I saw them before. I also saw some chickadees in the trees.
Why is it warmer when it’s cloudy then when it sunny sometimes in the winter?
Why was that one duck out there in the water by its self?
What were those crows doing in the field?
