'How long will this go on?' seemed to be what this adult male is saying, as one of his two juvenile male offspring beg. He and mum fed both birds, and the fourth photo is of him cleaning his beak after feeding. I am wondering when they will cast off their young in order to breed again next year - or they may be preparing, but the current ones still stay around? As I type, there is a lot of noisy gang gang activity around the place.
