We have a pair of crows in the garden, as far as I remember I've never
seen
them here before.

What do they feed on?

they will eat bread but their natural diet is carrion (by crow most people
mean a carrion crow, as opposed to a rook or jackdaw). They will also rob
nests and eat grain or roots but road kill is probably their staple .
