A 5 gallon bucket full of bb's launched with a sling shot will provide heaps of fun with the birds. Unlike the BB gun, you can load a dozen bb's into the slingshot and get a "shotgun" spread effect. This just get's rid of the nuisance without risk of killing the birds. But you'd be surprised just how much a stranded Booby will put up with for the free ride across the Pacific. As long as they aren't pooping on your solar panels
, or radome - then they aren't much bother whilst underway. Using any type of gun looking abject in port is gonna eventually attract attention you DON'T want.
I'm On point, On task, On message, and Off drugs. A Streetwise Smart Bomb, Out of rehab and In denial. Over the Top, On the edge, Under the Radar, and In Control. Behind the 8 ball, Ahead of the Curve and I've got a Love Child who sends me Hate mail. - (George Carlin)
