There won't be enough time to review the whole day today, but there are a few things to mention, and the first is something we haven't seen before.

The female was again getting quite restless in the nest cup around 5.40am, switching positions and turning around.

Towards 6.00am it looked like she was becoming motionless, and about to produce her next egg:

A minute later and she was out of the cup and wandering about the box:

She could hear her partner outside, and positioned herself by the entrance. Sure enough he arrived, and breakfast was gratefully received:

After having returned to the nest cup and looking decidedly sleepy, the male suddenly entered once more with another meal just 70 seconds later:

And if you're on a mission, why not do it again a minute after that:

Over the next 10 minutes she tried everything from trying to sleep, walking around the box and performing her bounce-walk.

Clearly she wanted to lay an egg, but it just wasn't coming. At 6.12am she gave up, stretched her wings and left:

A confused male brought more food a few minutes later:

At this point we had just switched on the computers and saw an empty nest, which is nothing unusual for that time of day. Given this, the lights were switched on a little earlier than the timers automatically do at 7.00am.

Minutes later and she was back with some more fine material:

But she didn't leave ...

Five minutes or so were spent inspecting the glass, walking around and checking the nest:

By 6.46am she had positioned herself over the cup and again it looked as if nothing was going to happen. To pass the time she decided to have a little preening session:

And then it was head under wing for a few more minutes and whilst in that position she started to make her now familiar clicking sounds, egg labour had started.

She stayed with her head tucked under for a couple of minutes as the clicks got a little faster. At 6.54am she raised her head and was very much beginning to go through the motions.

Her beak again opened and closed almost in rhythm with the sounds:

Not wanting to miss an opportunity, the other side camera which is patiently waiting in the wings for the chicks to arrive was switched on, and has now come nicely into focus.

Just before 6.56am she turned in the cup to continue her efforts:

A couple more minutes passed and a surprise arrived, the male with food. Still going through her labour she accepted the meal:

He probably didn't realise what she was in the middle of, and after he left she continued to sit there, clicking away:

The clicking sounds stopped just before 7.01am and she took 2.5 minutes of rest before lifting herself out, which is quick by previous performances:

And less than five minutes after her fourth egg had been laid, she was out of the box again:

Fascinating stuff, and good to know that the lights don't put her off, or the male bringing in food !

She looks more relaxed about egg laying now than when she laid the first. Her face was quite contorted at times that morning. You could even say that at times she was showing signs of boredom this morning - but there again she had been up a little while before she produced one today.

The beginning, middle and end of her seven or eight minute labour is here, along with the male bringing her food. Again you might have to turn up your speakers to hear the clicking sounds. It's quite a large file, and if you have a slow internet connection stick with it, it's worth seeing.

Something else of interest happened last night, and it concerns the male.

He was very good at bringing feeds for her before the light finally faded for the night, but one of his visits in particular stood out.

He did try and get back in for the night ... or at least gave it serious consideration.

At 8.07am (which would have been early for him to go to bed) he brought in food, fed it to her and then moved over to his favourite corner. He then decided to do a spot of wall pecking before venturing nearer the wife. By this point she had stopped making disapproving noises and couldn't really be seen as she was so low down in the cup.

As he stood over her, you could visibly see the predicament going through his mind, as his crown went up and down with his thoughts:

She wasn't going to kick him out, but on reflection he decided that it was best to leave.

A confused and possibly thoughtful male can be seen here.

We're 99% sure (you can never be 100% with Blue Tits) that she laid her fourth egg today. Looking again at the videos from the 25th didn't turn up anything new.

The remainder of the day should play-out in much the same way as previous ones, and more soft material will be brought in from time to time.

If you see something on the WebCam, let us know. She is most likely to reveal them again later this evening after she gets deep down in the nest from about 7.15pm onwards, if she pops out again.

And finally, earlier this morning we caught sight of another female Blue Tit who is still in the process of collecting material for her nest:

She flew off over a hedge towards the house next door, so she can't be far away.
