Barry, I hope your medical issues improve. It is not a lot of fun to be stuck inside.
We border a green belt and there are no fences so you can pretty much always see some birds, squirrels, people, aircraft, cats, dogs, and other assorted things. We have some big Pine Trees and Blue Spruces which I like to look at and especially under. I also look at the night sky especially when there is something unusual taking place. I have always been an amateur astronomer having big telescopes in the past. I am always testing some binoculars so I look a lot at different signs and license plates to test for sharpness of my latest acquisition. I look at the black smoke stacks on the neighbors house against a white sky to test for CA.
