I had some questions about my tree at the newer house. I suppose it is like a small inedible crab apple. My husband thinks they are 1cm in diameter, and he can take a closer picture of them perhaps on the weekend. This is a 2 year old photo.
We haven't seen any birds eat them. We don't have squirrels in Australia. We have a possum which is different to yours, but not where we live, though they should be here.
