The tiercel flies fro the nest ledge leaving the falcon to sit on the nest scrape.

I commented that yesterday was the best session of the season so far but that paled in to insignificance compared to today. It seems that incubation has started,  the female has started to brood a clutch of eggs.  When I arrived at the hide in the early afternoon, at first there was no birds present on the ledge but within minutes the falcon flew in and sat quietly in the scrape.  She remained there, sitting on the nest for around 2 hours 30 minutes when suddenly the tiercel landed next to her, he stayed for a minute or so and then flew off and landed on an unusual perch – a dead gorse stump – to the right of the ledge. He remained their posing beautifully for a further 5 minutes or so, all the while screaming loudly. The falcon meanwhile had left the nest and the ledge was quiet for a minute or two, but not for long. The Tiercel was first back but he just landed there and didn't go in to the nest scrape.  Then with much screaming, the falcon returned, the tiercel left and then she quickly made her way back on to the nest scrape where she remained,  sitting as before.  She was still there when I left at 1730. If she is not started incubation then she is very broody and I suspect that either there is a full clutch or she will lay imminently.
