At the moment I'm living in the country, and it's amazing how many birds you see out here (including wild rabbits, badgers, etc). I've been fascinated by the Canadian geese that I see flying overhead morning and evening and that are in the field down the road from where I live.
I found that they can be a nuisance to some, or that they can be hurt when they come into contact with aircraft, etc. Here's an ingenious way to stop the birds from getting into those areas without killing/harming them. I also like that rescue dogs are often used.
