Unless it's a raven, I don't have the reference page to help me know the difference
raven. skinnier head proportionally to it's body, and even with a straight on photo you can tell the beak is thicker and longer (the depth of field is an indicator). crows also have flatter heads and are generally less fluffy than ravens (except for carrion crows but their eyes face more forward and have pupils). also the scale i think. ravens are 50% larger
