Had a look at the recording from last night and I think Carson was on the nestledge just after 2000h and I'm not sure if/when he left but then Beatrix turned up around 2130h as per usual.
At 0545 one chick took off from the ledge (pretty sure Carson), then Ivy arrived with food and then there were three chicks on the ledge for breakfast and Dad beat a hasty retreat followed by one of the boys then followed by the other boy about 10 minutes later. Beatrix hopped her way down the ledge with the remains of the meal and one of the adults or chicks was doing aerial acrobats north of Portage. Beatrix eventually gave up her meal and followed the rest at 0602.
At 0636 Princess arrived and made off with the remnants of Beatrix's meal only to return about 30 seconds later. A quick dash down the ledge and she was off again.
Beatrix returned to the nestbox at 0751 and then 15 minutes later she wandered down the ledge to look for her, now missing, breakfast. A little rain dancing on the ledge at 0807 before taking off again at 0810. Back to the nestbox at 0830 and a food drop from Ivy just after 0900 ...
