I’ve often seen great-crested grebes go through their head-shaking, ritualised preening display, but at last this morning at RSPB St Aidan’s, we got to see the presentation of beakfuls of water-weed and the penguin dance where the male and female rise from the water, breast to breast, paddling furiously and swaying heads. They appeared to drop the weed as they started this routine. They then returned to head-bobbing display.
We’ve yet to see the ‘ghostly penguin’ and the ‘cat display’ which apparently start off the whole routine.
