Cartwheeling White-tailed Eagles

Very distant record shots of a behaviour that I have long wanted to witness - mutual talon-locking and aerial cartwheeling in White-tailed Eagles. I photographed these immature birds in the Outer Hebrides a week or so ago. After a bout of calling and rapid flying from a single bird another individual appeared and then quite unexpectedly the birds locked and cartwheeled rapidly downwards. The cartwheeling lasted only a couple of seconds and I was lucky to grab these shots. Next time, overhead please...
