park…

Today when I went down to the park for the second time, the sun was setting and it was getting colder. When I was on the breakwater, I saw some seagulls. When I was in the park I took some photos of the sun setting. When I was done taking photos of the sun setting, I saw some varied thrushes when I was walking and decided to try and take some photos of them. While I was chasing the thrushes around, I saw a raven in a tree. All the photos I took of the thrushes were blurry so I deleted them. When I was walking back towards the battle site bench, I saw a sparrow that I didn’t know what it was, so I tried to get some photos of it. But those photos were blurry as well. I chased after the sparrow for a while, but I never got any good photos of it, and I didn’t see it that many times after I first saw it. When I started heading back home, I heard it so I looked for it some more, but I only saw a song sparrow.
Why did all my photos have to be blurry?
Why did I only see one raven?
Why dose the sun set earlier now?
