Went through playback and this was this morning's timeline ...
0500 - all three kids in the box
0525 - Beatrix took off down the ledge, Cade & Carson stayed in the nestbox
0527 - Cade hopped down to follow his sister
0528-0540 (probably about 0530) - Cade took off from the ledge
0609 - Carson took off from the box
0925 - Beatrix found the leftovers either Carson found earlier or the remains of the first meal of the day which Carson snatched earlier (couldn't see a food drop, so could have been remains in the box)
