BAGS! All kinds of bags I’ve seen living in trees. It would be because it’s so-o windy in March in the winter and the trees are barren they just invite bags to come up. For example:
I was on University Ave at Queen and I was taking pictures of the bag in the tree when I saw the Hawk, just a little ways down. So I took pictures of it, and before I knew it, there was a crowd there taking pictures with me!
