All the chicks were in the box last night to sleep then until about 0530h this morning when Beaumont took off onto the building roof and Bristol staked out her spot on the nestbox roof while Bishop tried to yak up a pellet and Belle finished off breakfast with mom.
Beatrix parked herself on a post on the roof after breakfast with Belle and then just before 0600h, Belle hopped off the box onto the roof to go join up with Beaumont and Bishop joined Bristol on the roof (the names are working out better than anticipated
) With Beau watching intently, Bishop flew about 20 feet across the building roof from the box roof (figures our pilot is the first to get air under his wings). Bristol took a few minutes longer and was doing a lot of practicing with her her tail gear before she jumped down from the box roof - she's further along than Belle but Belle is much more gung-ho, very little hesitation when she decides to do something it seems so far.
Kids remained out of the box until Beaumont checked out what Beatrix and Beau were "up to" at the nestbox around 0800h, then he returned for a private snack from Beatrix around 0900h leaving a sibling - I think Bristol - playing with some roofing fabric that has come loose (they all like playing with that stuff!) in a shady spot not far from the box. Bishop and Belle/Bristol are out of camera view, likely in the shade (there is a lot of shade on this roof at all times of the day - nice feature). Beaumont hopped down on the roof and ran off to Bishop followed by Bristol (?) a few minutes later. Beatrix in the meantime finished off the snack and parked herself for kidsitting by the nestbox.
Since then, Belle every so often runs in and out of camera view, occasionally followed or following one of the boys - I'm inclined to think Beaumont but can't be sure. The box has been empty for the last 1.5 hours with just Beatrix watching from the roof of the box. The wind is starting to pick up and it is clouding over - will be interesting to see if the kids come back to the box as the winds come up (gusts in the area are already up to 40km/h)
