The calm before the storm.

Saturday 1st June
This is the day we think could be departure day.
Malcolm put a timer switch on the camera, and set the video recorder,
in case they did a dawn break, but they are still with us at noon.
The birds are very restless, with lots of preening activity and
occasional bouts of violent wing flapping.
Its a beautiful day quite breezy, but with a clear blue sky
and bright sunshine just
right for a maiden flight (apart from the fact that 2 magpies have been seen
in the garden on several occasions). One
chick actually hopped up to the hole, staying there for a few seconds,
before scuttling back, and retreating firmly into the nest cup, apparently
overcome by his daring. Another chick picked a small piece of dried moss from the
nest, and held it in its beak for a while a comfort blanket?
|

Beauty brings the rations.
|
The activity increases at one time 6 chicks were all preening violently,
and occasionally a little face could be seen underneath them, in the nest
cup. This sort of behaviour was
seen last year. Then the
activity in the box increased from about 3pm, the first bird left at 5pm
and it was all over by 5.30pm.
|

Chicks everywhere!
|
This year it is a different story. One chick went up to the hole,
and was looking out when a parent came, and fed the chick at the hole.
Another time, a parent pushed past a chick to feed the others.
Shortly after this was written, a chick went up to the hole, looked
out for a while and much to our, and its(?), surprise, flew. This was at 12.25pm. This
must have been the bird we called Boss yesterday. He was so much more
self confident and aggressive than the rest. We thought the
others would follow quickly, but at 5 past 1 they were still in the box.
It is now 20 to 5 in the afternoon, and still we are waiting.
The chicks alternate between periods of rest, when they cuddle close
together in the nest cup, and bouts of frenzied preening, wing stretching
and occasional violent wing flapping. The
parents are continuing to supply plenty of food, assisted some of the time
by our offerings from the mealworm feeder.
|

Where have they gone?
|
Finally, at a quarter to 6 a second chick left the box.
|

No - you go next!
|
Unusually, we saw it fly away from
the box and cling clumsily to a branch just outside. A few minutes
later it was off again and vanished among the foliage. We had
thought it would be too late, and that they would all stay another night.
Now at 7pm, it does look as though the last 5 will stay.
Here they can be seen huddled together near the front wall of the
box.
|

Is this the way out?......
|
Here they are considering a possible return to the safety of the nest cup.
|

...and then there were four.
|
Having assumed that was it for the night, we set about getting something
to eat. A great mistake as we missed seeing the third one depart.
It must have been about 5 to 8 will any more go?
A parent is certainly still trying to coax them out.
So these four will presumably stay one more night in the box. We
will set the recorder to start first thing in the morning and hope that we
record them even if we are not awake to see them!
|

|
Sunday 2nd June
As expected, Beauty's remaining four chicks flew first thing this
morning. Unfortunately, owing to a switch being left in the wrong
position, the VCR did not record their going and when we got up at a
civilised hour, there was nothing to see but an empty nest.
So here's a picture of Battler with her ever hungry chicks. They
are growing fast and will be gone within the week. Lets hope they get
a good start to life outside the nest with some warm, dry weather!
|

MORE!
|
Having now watched Battler's chicks for most of the day, it appears that
they are much noisier that Beauty's chicks. Whether they really are
hungrier or merely appear so makes no difference to their continual
racket! We were worried that perhaps they were getting neglected, but
during the early part of the day at least, they were fed pretty
frequently. The frequency that they were fed tended to drop off towards
the end of the day - perhaps Battler and Victor were tired!
|

Please come back soon!
|
On Wednesday 28th May, we mentioned that these chicks would sometimes become
inattentive when one of their parents was playing games with the grub that
had been brought into the nest - sometimes appearing to offer it to one
chick, before removing it and offering it to another. This would lead
to a gruff "chirrup, chirrup" from Victor to wake them up
again. No longer. The chicks look as though they could eat their
parent bird when it comes into the nest, and if it doesn't leave food for
them all - an impossibility - they are still yelling for it even when the
parent has gone.
|

Surely some food will come soon?
|
And when she has been gone for more that 30 seconds they peer our of the
nest box hole looking for her to reappear!
|

At last, they haven't forgotten us!
|
But the look they give when food arrives....
|

That wasn't much!
|
....isn't much different from the one they give when the food bearer
departs!
|

Just give us the food!!!
|
As you can tell from our comments, we think these chicks have but one
thought on their minds - FOOD!
Just five days to go now.
|

We're STILL hungry!
|
Monday 3rd June
At the start of the day, it was the same story, the chicks all crying out
for food.
|

That's more like it.
|
But now, Battler and Victor have discovered the mealworms in the dish on the
dustbin its only 7 or 8 metres along the passageway at the side of
the house.
|

Not another one?
|
They have been
running a regular shuttle service, and now the chicks are well and truly
satisfied. Yesterday we were
concerned that they were not getting enough food, because they seemed really
desperate to be fed all the time, and often the food brought in was so tiny
that we could not see what it was. Now
the chicks are snuggled down peacefully in the nest cup, and when Victor
brought in a mealworm he had to chirrup quite fiercely to persuade a chick
to raise its head.
We counted up later and found that in the half hour period from 9.10am,
the parents brought food 43 times - that's once every 42 seconds. Even
these chicks' guts cannot continue to digest it at this rate.
|
|
Finally, they weren't even facing the hole any more - sleeping it off became
the priority.
|
|
By the end of the day, it's business as usual - the insatiable appetites had
returned.
The chicks became more active during the day.
They are occasionally leaving the nest cup, and one made a complete
circuit round the edge, before ending in a corner and having a bout of
violent wing flapping. This is
the first time this wing exercise has been seen, and there were one or two more
sessions later.
At the end of the day Battler was desperately trying to brood her
chicks. Whether she managed to calm them down eventually will have to
remain between them and her as we switched off and left them to it.
|

|
Tuesday 4th June
Life continues as before. The chicks did not seem so hungry
today. Here they are at half past six in the evening looking almost
contented. Except for one chick, they are not even keeping an eye on
the entrance hole!
|

|
The pictures today illustrate the differences between the head
feathers carried by male and female bluetits. This is Victor just
having fed the chicks. His top blue feathers are darker and more
streaky than those of females. He also has a white band separating
his head feathers from the navy blue collar around his neck.
|

|
This shows how different the female is. Her head feathers are not as
dark, they are more uniform in colour and there is no white band around the
neck, the blue head feathers blend into the navy blue collar.
|
|
This shows them both side by side. It is interesting how frequently
Battler goes to the left and Victor to the right. The differences in
their head feathers are common to all the males and females that we have
seen frequently at close quarters and learned to distinguish their sex from
their behaviour in the nest. Whether this is a difference only seen
during the breeding season, or whether it is clear all the time is not apparent
to us at this stage.
When last seen before turning the light off, Battler was roosting in the
nest box but sitting largely on the side and not in the nest cup.

Thursday 6th June
This morning, Malcolm took the ladder and looked inside box 1 where
Beauty and Beau had raised their brood. He was trying to settle the
question of whether or not all eight of Beauty's eggs hatched.
It was already clear that no remaining egg was visible to the camera and
when he looked and felt inside the box it appeared that no egg was hidden in
the nesting material either. It seems probable, therefore, that the eighth egg
hatched but the chick died at a fairly early stage. This is also
consistent with the fact that no egg has been seen during the 2½ weeks in
which the chicks were growing before they fledged. A similar thing happened
last year when the hen laid 9 eggs but only 6 chicks flew. However,
there were only 2 eggs left in the nest so we presume a 7th egg hatched but
the chick died at an early stage.
This year both boxes have had a very irregular pattern of egg
laying and hatching. The amazing thing is that the chicks fledge so
close together in time.
|

|
Victor appears to be doing all the work again. If we could have
brought you picture from yesterday you would have seen a very hard working,
but very wet Victor struggling to find food for his chicks in appalling
weather.
Here you can see that he doesn't even have to come fully into the box
now, the hungry chicks will come and meet him half way.
|

|
As this is probably the day before the chicks fly, it is not surprising that
they frequently exercise their wings to get them ready for the big
event. We don't often catch them at it, but here is one picture of a
chick flapping furiously.
|

|
At last Victor's hard work seems to be having an effect. You can see
that three of the chicks are not hungry enough to take notice of his
entry. Lets hope they are fit and well fed for their big day tomorrow!
|

Friday 7th June
Although we were expecting it, the departure of the first of Battler's
chicks at about 9.20am today caught us by surprise. We had the VCR on
but were running the webcam so we do not have a computer record of its
going. Looking at the tape, it was working itself up to it for a
little while before hand. As well as hopping up and down, looking out
of the hole and flapping its wings a lot, shortly before it went it hopped
up onto the nest box hole several times and looked out for a while before
retreating back inside. Suddenly it was gone without our noticing at
the time.
Of course, we thought that the rest would follow later today, but at the
end of the day, they are all still with us.
|

|
These three pictures show the box from the outside for a change. The
first shows Victor going to his usual staging branch before flying into the
nest box entrance hole.
|

|
This shows him emerging a few moments later. This time he doesn't seem
to be carrying a faecal sac - at least, you cannot see something white in
his beak!
|

|
Here are the chicks looking subdued after their brother has left them.
Later on they perked up quite a bit and at one stage we thought that another
chick was about to leave. It too hopped onto the nest box entrance
hole but it did not take the final plunge into the unknown.
|

|
During one of the chicks' more boisterous sessions, one of the un-hatched
eggs was moved to the side of the nest. Here you can clearly see it at
the bottom of the picture. It is difficult to realise that only 19
days ago these full sized bluetits emerged from such a small egg!

Saturday 8th June - the last morning
We have now had a chance to look at the video of the departure of the
remaining four chicks. We started recording at 5.30am and although
there was a fair amount of messing about, nothing of note actually happened
until nearly 6 o'clock. The first two chicks left the nest at about
7.00am and the last chick was gone by 7.28am.
The picture on the left shows the four chicks begging for food from
Victor. It is interesting to note that the parents kept visiting and
feeding the chicks remaining in the box until the last one had flown.
|

|
5.55am
"What's he up to? He keeps looking out of the box. He's
not going to disappear like Fred did is he?"
|
|
6.40am
"Now what's wrong with you lot? Fred's doing fine. Pull
yourselves together and come outside!" says Battler.
|

|
6.46am
This is a picture from a rather interesting sequence. Victor had
brought in some food but seemed strangely reluctant to let go of it.
Several times, even when he actually let go, he grabbed it back again and
offered it to another chick. On one occasion, he appeared to leave the
nest for about 10 seconds, still holding onto the food.
Eventually, he weakened and let go. We could not see what it
was. It was fairly small, similar in length to a chick's beak, and was
white in colour. It must have been fairly robust physically as it took
a fair amount of tugging. Could it have been a piece of peanut?
|

|
6.58am
At last one of the chicks begins to realise that it is getting serious
and starts to get some exercise! The others appear to be hoping that
this thing will go away if they ignore it.
Shortly after, at 7 o'clock, one chick went immediately followed by
another
|
|
7.03am
These two birds were distraught after their brothers (or sisters) had
left. They clearly didn't want to go at all.
|

|
7.10am
They look as though they have made a pact. "We're
staying put and that's final!!"
This soon broke down and it became clear that one chick may have been
frightened of leaving- but the other was terrified!
|
|
7.24am
One chick seems determined to hide - and the only place he could think of
hiding was underneath his brother! For some time, one chick kept
following the other around trying to hide beneath him.
The last but one chick flew at 7.25am
|

|
7.27am
"Now look here lad....."
This was Victor's last visit. It seemed to do the trick!
|

|
7.28am
The last shot of a chick (just) in the nest!
|
|
7.29am
That's it for this year!!
