The Crow went to a large Oak tree, walked around the tree and would make little piles of moss, and then went back and collected all of it in one big mouth full~

While visiting in the city, I heard the loud voice of the Crow, and went about seeing what it was up to.  There is a huge Holly tree in the friend's front yard and the Crow would fly down to the ground and collect soft mosses to line it's nest with.  I even watched it as it went to a large Oak tree, walked around the tree and would make little piles of moss, and then went back and collected all of it in one big mouth full. They are such wonderful birds to observe, and way too smart~
