I returned to have a look at how the owls were getting on. I managed to record several shots of the adult as it went about its daily routine while resting up at the burrow.
A good leg and wing stretch
Breast feather preening
Wing feather preening
A good head scratch
The owl disappeared into the burrow and I think it fed on something. Here it has re-emerged and is cleaning its beak on the rock. Note the remains of feathers on the talons.
Post feed talon cleaning
Some further housekeeping
A regular upward glance which I presume is a predator check
A quick forty winks. It would take short power naps between 360 degree scans of the surrounding terrain
