No, scouts still do have them. When I was growing up every kid in the neighborhood had a pocketknife, scout or not. Nowadays parents seem to think it is dangerous for kids to have one. It's is all about how they were brought up using one and properly instructed in its' use.
Starlings and house finches(sparrows) are a nuisance. Here is a link to a bluebird website that shows pictures of sparrow attacks on bluebirds. True sparrows are truly beautiful. House finches are the nasty dirty little birds.

This website is great if you are looking to keep bluebird boxes.
