park

Today when I went down to the park, it was sunny and frosty and there was some snow on the ground.
When I was across the road from the harbor, I saw some ravens in someone’s yard.
When I was out on the breakwater, I saw some goldeneyes, wigeons, ducks, and mergansers out in the water.
When I was in the park, I saw some Varied thrushes on the trail and in the bushes.
When I was near the battle site bench, I saw a flicker fly up from the ground and into the trees and I went to get a better look. When I was looking at it a raven flew by and the flicker flew to another tree.
When I was at the battle site bench, it was low tide, and I saw some sea gulls and crows out on the beach.
I also saw an eagle land on the beach out by the water by two other eagles.
When I was on the trail by the river, I didn’t see any birds.
When I was on my way back home, I saw some more ravens.
Why was it frosty today?
Why were the three eagles out on the same place on the beach?
Why did the flicker fly off the ground?
