Is it possible to teach tricks to crows? Or do they naturally pick up the skills they need to adapt to modern life?
Sir, A couple of years ago as a friend and I stood in our park, a crow flew down a few feet away, seized a foil packet lying on the ground, shook it, then planted one foot on the closed end (“Stone the crows, birds are bright as children”, July 26).
It inserted its beak into the other, torn, end and poked away until that end was fully open. It then lifted the bag with the other foot, shook it and ate the crumbs that fell out. I wonder how it learnt to perform this feat in the first
