Hindsight is always better!!!
I was near the outer entrance to my apartment door when something caught my eye and turning around I saw Benny the beautiful bluebird standing on an outside branch of the tree which he rarely does. Usually, he is further in the tree where his wife and chicks are. All of a sudden I saw him dart at something in the tree and because Seymour the squirrel blends in so well with the wood it took me a second to recognize him.
I immediately got my camera out and took a few shots of Benny sort of playing a game with Seymour as if to attack him but all the latter did was wrap himself tighter around the bark blending in and almost invisible. There wasn't any actual contact between them and I started to think if I had ever seen squirrels and birds fight but I hadn't! Soon both disappeared and so I went in.
As I looked at the pictures I realized I should have turned on the movie button and maybe I would have seen more! I know for sure that is Benny in the second picture and Seymour in the 4th but I have no idea who is in the first. My instinct was that it was Seymour in the first but then again I wouldn't bet on it. I, also, know both were/are in the tree in the 3rd picture but where I couldn't tell you.
I was interested in the birds versus squirrel fight that I googled it, binged it but except their fighting over birdseed I really didn't find an answer!! Besides what birdseed would be in a tree without any feeders??
Next time I will make a video and get some answers---maybe--and some better shots of the fighters!
