 Crows will not only remember your face and go after you repeatedly if you bother them, but they will also teach other birds to do the same. Their scolding and physical harassment can last for years, possibly for the life of the bird.

We are host to a number of Crow sp in our garden - from small to large: Jackdaw, Magpie, Hooded (Grey) Crow and Rook. And they wait for Rod every morning as he puts out bits in the place reserved for Corvids. I swear, they can talk! We enjoy them, in spite of the fact that many take out after them, saying they take young chicks, eggs. Which I am sure they do - but we have never noted an imbalance.
