We went to Leighton Moss yesterday and just as we got into the hide we heard the magic words "bittern to the right, flying over the field". The bittern is one of those birds which is exceedingly elusive, and each time we go to the reserve Q is desperate to find one. I failed to see any wings of any sort, bitterns or otherwise, Q said she saw a brown blur in the appropriate place, but then rather blew her ornithological knowledge by whispering to me that she didn't realise they could actually fly. Luckily no one else in the hide heard her comment as we were in the company of EXPERTS. The two bittern spotters each had lenses the size of small sheds and as they left to see if they could follow the flight of the bittern a derisory voice was heard saying "Spotters! pah, they're not birders; you need binoculars, not a camera to watch birds properly". We didn't have our binoculars; but even if we had remembered them, they would not have passed muster in such erudite company. We did have our cameras, but again our paltry lenses couldn't put us in any spotters' league. Anyway we don't really spot let alone identify many birds unless they stay still for about 5 minutes.
The robins of Leighton Moss are not at all camera shy and are willing little posers. The top left robin was flitting about near the reed beds and came and ate food out of one of the visitor's hands.
The marsh tit was a first - luckily for us there was an identification board right near the picnic table.
It's a long time since I have seen a greenfinch.
The reasons for the cages around some of the feeders became apparent!

Project in progress (part 3)
Lesson learned, don't flap around when fragile butterfly wing bits are on the microscope slide as they have a tendency to catch the breeze and float into oblivion.
This was taken from the upper surface of the butterfly wing, the blue colour isn't obvious as the light is shining through from underneath. What I found interesting were the little scale structures. Are these going to grow into larger scales, or are they subsidiary? Interspersed among the scales are hair like structures (are they hairs or modified scales?) (Addendum: I've just found out that scales are modified hairs).
I took some pictures at higher magnification, but will need to do some serious Googling to see if I can find anything about the details of types and forms of wing scales. Initial forays into the ether have not been very successful.
Scales were removed using the sellotape method and I then looked at the wing. It would seem that the scales are laid down on a membrane.
The following two images show the same section of wing taken with top lighting (top image) and transmitted light (bottom image).
It is clear that the scales on the upper surface of the wing are quite different is shape to those on the under surface.
Top lighting (top image) shows the blue colour of the upper wing surface. The transmitted light (lower bottom image) seems to show more detail of the scales.

Sparrow and some animation
The sparrows are really making the most of the bird feeders, but one of them doesn't quite seem to have the hang of it - or perhaps it suffers from motion sickness.
There has also been some other displacement activity.

Project in progress (part 2)
It was possible to look at the butterfly under the stereoscopic microscope without having to take it to pieces. However, in order to get a closer look, I needed to get out the compound microscope which unfortunately meant that this pretty little creature had to be dismantled.
Part of the wing was removed and viewed with top lighting. The scales overlap, like slates on a roof. Long hairs are present in some areas of the wing.
The wings were fringed with longer multi-toothed scales.
I removed some of the scales using sellotape in order that I could view them using the transmitted light shining through from underneath.
The next set of pictures is of strewn scales from the wings.

Project in progress
I set up the stereo microscope for those first views, and took pictures with a Dinoscope lens that replaces one of the eyepieces and is directly connected to the computer. Other pictures were taken with the set up as shown below.
The following pictures show the start of the project. Lighting is always a problem, getting sufficient light with no shadows. Then there is the problem of depth of field.

Downs and ups
The down was a sitting down. I believe that it is impossible to sit on a bookcase full of books without realising (even if said bookcase has somehow been swathed in a jacket carelessly thrown at it). The worst that a book can suffer under said carelessly strewn jacket and then my backside, is a creased page or folded cover. The same cannot be said of a Kindle alas! This I found to my cost the other day. As I recovered the Kindle I saw to my horror that the screen now resembled Etch a Sketch on a high, and accessing any of the scores of books I have stored on it was a total none starter. Yes, I had managed to sit on a virtual bookcase of books.
A lesson learnt the hard way, though at the end of the day, the Kindle is just part of the physical "stuff" that fills our lives, useful and fun but not essential. Luckily for me I was able to go out and get a replacement, and thanks to the wonders of technology all my books were still out there in the ether for me to restock the virtual shelves.
The up is absolutely not "stuff" that can be easily replaced; it was seeing the wonderful spectacle of a starling murmuration. We went out to Leighton Moss one afternoon last week and watched the amazing massed balletics of thousands of starlings as they gathered into a huge crescendo of movement before finally all coming to land in the reed beds.
Attempts at capturing it all on camera merely give a taste of what it was like. Distance and fading light were not conducive to getting good images.
Such was the spectacle that we went again yesterday to see the incredible sight. We put cameras aside and immersed our eyes in the experience. It started with small cohorts of birds which gradually joined forces to form a huge shape shifting pattern, serpent like sliding over the hill top and then morphing into a great fish like creature ebbing and flowing as more birds joined. As the light caught wings and bodies there was a constant flux of pattern and motion. For their finale, we saw a turn in direction as the shape became a funnel and the birds poured themselves into their night time reed bed roost.

Homing pigeons
I've just finished a book about the code workers at Bletchley Park and am now reading Ben MacIntyre's Double Cross:The true story of the D-Day spies. I had just been reading about the deployment of pigeons and their use in espionage (apparently they had their own section in MI5: The Pigeon Service Special Section BC3). Then yesterday, I read this in the news . It will be interesting to see if they decode the messages.
WWII carrier pigeon remains found in UK chimney by reuters
All this pigeon stuff got me remembering. My father was a great one for keeping pets and livestock. Among the many animals we had, pigeons had a high profile. We lived in an ideal place . The rectory had vast outhouses and one of the lofts housed the pigeons. I remember the tumblers and tipplers doing their acrobatics, the fantails strutting their stuff. We also had homing pigeons and often two or three of these would be bundled into a box and taken with us on a Sunday as we headed to church in one of my father's parishes. The pigeons did not have to attend the service; they were let loose as we went into the church and then on our arrival home, we would find them back safely in the loft.

Insect eaters
Over the last few days I have uploaded pictures onto my photoblog of one of the insectivorous plants I have (Drosera paradoxa). The idea was that as the series progressed I moved closer to the plant. Over the weekend I got out the microscopes and developed the theme a bit further.
Utricularia (Bladderwort) was my starting point. I've never kept this species before, though I have seen it growing in the wild in the waterways in Holland. I bought a plant a couple of weeks ago and its delicate structure belies its sophistication as an animal trapper.
Pinguilica (Butterwort), a favourite because of its almost all year round flowering. Many insectivorous plants are very canny in that they grow their flowers on long stalks to ensure they get pollinated by those insects that haven't ventured low enough to be trapped and caught.
Butterwort leaves are sticky and glandular and under the microscope the stalked glands can be seen.
Sarracenia (Pitcher plant) was next for examination. The downward pointing hairs and sticky secretions became obvious as the "lid" to the pitcher was put under the microscope.
Finally I couldn't resist the Drosera (Sundew), always eminently photogenic.

I put a couple of stems under the microscope and attempted to find some of its subterranean bladder traps, but did not meet with much success, not least because I was not quite sure what I was looking for. A future project methinks.

I looked at the inside of the pitcher too, expecting more downward pointing hairs, but didn't see any. Again, another project for further investigation. Maybe they are smaller ones than those on the lid, perhaps they are not so common in plants in autumn because there are no insects. More investigation and Googling research are required.
Finally I couldn't resist the Drosera (Sundew), always eminently photogenic.

A reality check after all the glitter
We took the scenic way home after the Christmas tinsel bombardment and drove over narrow roads across wonderful countryside near Bleasdale; incredible views in all directions, to the Lake District and across to Morecambe Bay.
The tranquility and the wonderful colours of autumn made up for the brashness of the morning's experience.

It's only the middle of October for goodness sake!
We visited a local garden centre yesterday and were overwhelmed with an enormous display of things Christmassy; much of it exceedingly tacky and all of it, very expensive.
Glistening ice clad polar bears, tree lights that looked like real flames, Father Christmas in every size, shape, and form (some rather scary looking - perhaps trying to catch the Hallowe'en market at the same time).
Feathery angel wings .... where on earth do they come in the scheme of things?
How can there be fun and excitement to the build up of Christmas if it starts in the middle of October? Surely a parent's nightmare, with this time scale children will no doubt have changed their ideas multiple times before Christmas Day does finally arrive.
It's not just the children either; how about an Advent calendar for your cat or dog ? Next year no doubt the rabbit and guinea pig gap in the market will be filled with their very own snack filled calendar. If that is not enough, try a Santa outfit for your dog.
Or am I just being a grumpy old Scrooge?

Unidentified flying livestock
This erudite beastie was found lurking on the Ipad. Having ascertained that it was not a bed bug, it got the photographic treatment under the microscope, After a quick bit of Googling it was identified as a woolly bear aka a Carpet beetle larva (aaarrgghhh!!) Now all that remains is to check that there are no others lurking around to munch their way through clothes and carpet.
Perhaps I should have fed it to my latest sundews.
