Park

Today when I went down to the park for the first time, it was mostly cloudy, but there was some sun.
Just after I’d left the house, I saw a black cat that is sometimes around the neighborhood with a yellow and green colored warbler hanging limply in its mouth. It walked past me and behind a fence to were I could not see it.
When I was on on the boardwalk by Sage Rock, I saw some fuzzy black and orange caterpillars on a Crabapple tree, they’ve been there for a while, but there seem to be fewer of them now.
When I was nearing the battle site bench, I saw some sea gulls and a great blue heron out on the beach.
When I was at the battle sight bench, it was low tide and I saw some sea gulls, ravens and an eagle out on the beach.
When I was on the trail by the river, I saw three juvenile eagles all in the same area across the river. One of them flew off and scared away some of the sea gulls that were there.
When I was on my way back home, I saw some robins in someone’s yard.
How did the cat catch the warbler?
How much longer will the fuzzy caterpillars be there?
Why did the one eagle fly away?
