Dog sees squirrel on window gets excited

This is my 11 year old Jack Russel Terrier Molly getting a bit too excited about a squirrel. Sometimes I fully recline this chair so she can comfortably look at all the little birds that congregate outside the window. Today was the first time a squirrel showed up and Molly couldnt contain her excitement. She fell between the recliner and the window trying to get a closer look. Shes completely fine but is now glued to the window.
