Does anyone know where I can get a cunning tricksy peanut dispenser aimed specifically at corvids? As I understand it, corvids are particularly smart, and so they can figure out how to operate some simple mechanical devices. I love corvids, especially jays, and I'd like to encourage them to visit more regularly, but the trouble is we get a lot of pheasants coming, and whilst they are gorgeous, they are pretty much hoovers and half a dozen don't leave anything behind for the shy jays. Any ideas?
