Well it looks like the boy had a Friday night out and didn't return to share the box last night, but he did pop in just before he left with a quick snack for the female at 7.27pm.

The female started to stir from about 5.00am onwards, and the side camera wouldn't have known that she was in there:

By 5.47am, after having moved around the nest cup quite a lot she had settled into her labour position, but today she was so low down that a video isn't really worth posting.

The first clicking sound was heard just before 5.48am and at 5.53am she raised her head and it looked like the third egg had been laid:

After turning again she lay there resting and then it was head down and tail up just to check she could count to three:

She then carefully manoeuvred herself out of the cup and and for the first real time this season she displayed what we have come to call 'nest cup diving'.

This is where she spends time getting really deep into the nest to check her eggs. She will also do this when the chicks have hatched, and sometimes rather than moving eggs or chicks around she will remove bugs and other insects that might be present:

During her housework she could hear distant calls outside, and moved herself out of the nest cup. The calls became louder and the male was back, with one of his earliest food deliveries yet:

The female is still resting, hears her partner and gets fed here.

She rested for a further five minutes before walking around the box, the went back into the depression and started to preen.

It was only nine or ten minutes after her egg labour, and the male was making up for his night away. She heard him land on the side of the box, called at him, and in he came - food and all:

It's easy to read human traits into the birds sometimes, as it' easier to convey what happens, but this chap surely had something to prove ... just 2 minutes after the last, he was back with his third offering in 10 minutes.

But his delivery was a bit clumsy:

By 18 minutes past the hour she had suitably recovered, although it did look like she was listening out for the male again before she started bouncing round the side of the box, before leaving:

A livelier female perks up and leaves here.

Another egg to carefully look after, so more soft material was added to the nest:

And shortly afterwards superman was back again, but a missed opportunity was his gain as he ate the Caterpillar whilst hanging onto the outside of the box:

As the morning progressed their routines seemed familiar in character.

The female would bring material in from time to time, and the male would miss her, sometimes by seconds, but he always had food:

The nest is incredibly soft and warm in there now as we don't remember having seen a female do quite as much additional work as she has done over the past 3 days.

Lunchtime again saw a slow down in their activity, and the wind had picked up, so the cameras did nothing but spend most of their time recording moving feathers:

She did return once at 2.17pm, and then went out to enjoy herself until 5.33pm when she came back just to check:

Another 1.5 hours and she has just come back in at and looks like she might be happy to stay there for night. She's nicely occupied diving into her nest and wriggling her body to get nice and deep in the cup:

Of course she could pop out again, but hey - the male has just made four rapid food deliveries in 5 minutes ... is he after somewhere to stay the night again?

A few short clips showing a typical male today where he keeps missing his mate, and starts with the 6.45am food miss where he eats it. Oh, and at one point ... well you'll see ...

And to finish, a clip of the female just after she returned this evening, and she's enjoying her creation and doing a bit of nest cup diving in the process.

And the hunt still continues ...

... She has still yet to reveal a single egg to the cameras (as far as we know).

UPDATED AT 8.00pm

Well there we were, packing up our bags for the day and a quick check of the emails produced a real surprise ...

At 7.25pm the female at long last gave up her guard and revealed at least 3 eggs:

But are there four in there really?

The shape on the right-hand side of the other three could just be a feather ...

Mmm ... not sure, but many thanks to Ines from Germany and Susan from Oregon (USA) for very quickly tipping us off! We would have missed this otherwise.

Tomorrow morning we'll go back through the early morning video of the 25th and see, but that morning she bounced out of bed and left at 5.52am.
