The eyasses will become fledglings any day now. As we watch and wait for the big event(s), we get to watch eyasses that are now looking angelic after a “ugly duckling” stage, get ready for their big day(s).
On the video from this evening, you can see one of the eyasses jump at the window, around 6:40. As you can see from a section of the video and some of the photographs, the hawk is trying to land on the edge of a picture frame on the other side of the glass. For a species that is used to branching from tree branch to tree branch around a tree nest before fledgling, the lack of branches must be confusing and frustrating to an eyass being raised on a window ledge.
