I have two retired old ladies. The white one is as blind as a bat but manages to feed by following the others VERY closesly (hearing OK) and pushing them off when they are at the feeder. The other one is a lovely raven/black lady who manages to jump up on the perch every morning, points in the grumpy neighbour's direction and crowes cockerel like in the loudest voice she can muster. I have had them for 5 years, got given them by my brother who had them for 2 years and had inherited them when his neighbour died. So they are at leas 7 years old. They are such charecters and I love them to bits.
