Me too - but the tuskless cows in other parts of Africa don't seem to be as aggressive as the Zambezi ladies and I'd say the Zambezi ladies (esp the tuskless ones) get hunted harder than those elsewhere in Africa......... so that's why I reckon their being hunted could well be the reason for the added aggression....... hence my comment, but it's just one of my pet theories and I could well wrong.........
