How do you deal with a annoying robin who pecks on every window day and night it's so annoying It's not doing this because of it's reflection it will just stare at us we need a permanent solution?

get a bb un or airsoft gun. We had the same problem in our basement. One day our cat got down there now we never heard that bird agin. look just shoot it to pieces. preferably a 12 gauze pump action shot gun. a spas 12 would do. its a very effective shotgun. Waht about neiborhood gun laws???
