Bob appears to be giving some food to Becky - presumably for the chicks.
He clearly has a last minute change of mind as you can just see it still in his beak as Becky moves off the nest cup.
Finally he stuffs it down the throat of one of the chicks himself!

At the end of another day, Becky still has three, but only three, chicks. I'm sure that none of the remaining 6 eggs will hatch now.
Bob with the chicks.
A very late picture taken of, I think, Bob with the chicks.
