Butterflies of Wales

Posted in Education,Moths and Butterflys,Nature and Environment by AnnMarie @ Sep 19, 2008

The sunshine is back! So posted here, are 10 butterflies that you might see if you visit Mid Wales. I photographed all of them at my home in Dyfi forest.

They are:

  • CommaPolygonum c-album
  • Small tortoiseshellAglais urticae
  • Red AdmiralVanessa atalanta
  • Wall - Lasiommata megera
  • Small whiteArtogeia rapae
  • Speckled woodPararge aegeria
  • Green veined whiteArtogeia napi
  • Peacock - Inachis io
  • Small copperLycaena phlaeas
  • Painted ladyVanessa cardui

Just click on a thumbnail below, to start the slideshow (you can pause at any point) :

There are also a good few more butterflies in the area, like: Ringlets, Orange tips and Meadow browns. So if you are ever having a summer afternoon walk in the Corris – Aberllefenni region; keep your eyes open, you never know which butterflies you’ll see.

If you’d like hard copies of these & other pictures – butterfly prints & posters will be available soon from Poster’s Wales. To find out more about British butterflies try the Butterfly Conservation website.

Jay – Garrulus glandarius

Posted in Birds by AnnMarie @ Aug 9, 2008

The Eurasian Jay is a colourful member of the crow family and is resident across most of Europe. Jays breed in various types of woodland but prefer oak, for its abundance of acorns.

We are lucky enough to have a reasonable number of these rather shy birds, breeding locally. This year they have taken to visiting our bird feeding station. The other day I set up a remote camera to record the goings on; below is a sequence of 2 visits & flights away, just click the play button to view the sequence.

Jays really are very cautious birds but its well worth trying to get them calm to your presence, their plumage is truly stunning. You’ll certainly hear that they’re about, with the loud grating alarm calls that they make!

A British Summer

Posted in General,Nature and Environment,Photography by AnnMarie @ Jul 29, 2008

Sun, clouds, lightning, rain; yes it’s a British summer! The night of the 27th clear spells gave way to a hot (27C) & humid day yesterday, with very little breeze. That’s just what I needed to demonstrate an answer to Tamsin’s question … How do you take the images of the tree canopy that I see in magazines?

So off we trundled with tripod, camera & fisheye lens, we took 4 differently exposed views of the tree canopy & returned to the computer to process the 4 exposures into one high dynamic range (HDR) image. Whilst walking the conversation turned to "How are zoom lenses made?" – hmm, this daughter keeps me on my toes :-) Anyway the resulting image is below:

Foel Friog Tree Canopy

The full res image (not posted here) shows details of leaves & bark whilst retaining plenty of sky detail, all in all a good recommendation for HDR technique.

As evening came any ideas of a night’s astrophotography were blown away by rather ominous looking thunderclouds. An opportunity for an early night? Well maybe not, 2am found me sat in the bird hide watching some beautiful lightning & being lulled to sleep by the patter of rain on the canvas. Naturally I had a camera with me …

Lightning

Lightning occurs when droplets of ice & rain, circulating in the thunder cloud, build up electrostatic charge. The charge created can be huge and an equal but opposite charge is induced in the ground below the cloud. The highest electrical field exists on the tip of objects such as tall trees, electrical leaders form that eventually connect cloud & tree top and it is then that a huge discharge leading back up the ionised air, into the cloud, takes place. This is the bright flash that we most often see. Most lightning strikes are a discharge of negative charge from the cloud with a typical current of 40,000 amps; potential difference may be several hundred thousand volts. However lightning strikes that emanate from the top of an anvil cloud can result in a positive discharge, these bolts carry significantly more energy and are both rarer & more dangerous.

Lightning

Lightning storms in Wales are rarely viewable without a large amount of associated rain, so trying to keep equipment dry, whilst photographing the view, can be a bit tricky but well worth it I think. So Aberllefenni & Corris had a stormy night, but all seems fine today.

Trivia: Did you know that the path of a  lightning bolt may only be 1 or 2 inches wide but 1 mile long.

Toads & Frogs

Posted in Amphibians & Reptiles,Nature and Environment by AnnMarie @ Jul 20, 2008

And here’s one I prepared earlier, well not really I haven’t qualified for my broomstick yet! A few more trips to Dayagon Alley are needed :-)

What I really mean to say is that I took these two pictures in early spring but omitted to post them. Spring is a good time to see frogs & toads, they are busy mating or looking for a mate. This couple were certainly very busy:

_MG_0227-03Apr08-Edit-2   Common Toads (Bufo bufo) – mating

I so nearly trod on them whilst looking up for a bird, fancy that, making out on a track in broad daylight, the shock of it. Seriously though, Toads get quite determined, the smaller male climbs onto the female’s back and holds on tight – he doesn’t want any other males to dislodge him before he’s sure that he’s fertilised the eggs. This mating position is called amplexus and as is the case with our happy couple above, sometimes a female is ambushed before she reaches her watery spawning site. Toad spawn is laid in strings, as opposed to the clumps that are typical of frog spawn.

For comparison here is a picture of a common frog:

_MG_0609-02Mar08-pcopy-2   Common Frog (Rana temporaria)

I thought he looked rather shocked & lonely and it turned out I was correct … he was the survivor of a young grey heron’s attempts at clearing many frogs from this damp area.

 

Trivia Fact: Did you know that Common Toads can live up to 40 years of age.

House Martin Chicks

Posted in Birds,Nature and Environment by AnnMarie @ Jul 19, 2008

We’ve been a little concerned about the swallows & house martins this year; but all seems to be well now. Having heard of the poor weather in southern Africa just when their northerly migration was starting, it was worrying to see fewer than normal in the initial arrival. As time has gone on more & more have arrived such that we now have large numbers hunting for insects over the fields.

The house martin chicks in the nests on the house are now quite close to fledging, it seems quite a squeeze in those mud nests. In one particular nest the 5th chick has been pushed out, falling to his death in the nighttime but the other 4 seem very well, as per the image sequence below:

 

_MG_4826-19Jul08  Its squashed in here

 

_MG_4785-19Jul08  Incoming

 

_MG_4814-19Jul08  Some for you

 

_MG_4820-19Jul08   Oi! Give me some

 

_MG_4825-19Jul08    I’m going to swallow them both.

 

The parents are both hunting almost constantly through the daylight hours and with only 3 or so minutes between each foray there must be a large number of insects going in to the chicks!

Young Birds Video

Posted in Birds,Video / Podcasts by AnnMarie @ Jul 5, 2008

This spring we added a new feeding station for our wild birds. It seems to have been quite a hit, especially with the youngsters. Some of them are very quick to get to grips with things, like the sparrow fledglings; others aren’t too sure at first, like a certain little blue tit.

Anyway I’ve pieced together a short (~3min – 10Mb) video for you to take a look, just click the link below & then the play button …

Greater Spotted Woodpecker

Posted in Birds,Education by AnnMarie @ Jul 2, 2008

The greater Spotted Woodpecker (Dendrocopos major) is the most common woodpecker in the British Isles. In fact there are thought to be about 25 million of them living in Europe.

Greater Spotted Woodpecker - juvenile Image Details:

Focal Length 700mm
3 exposure mosaic

Juvenile – note red cap

Click image for a larger view …

I have a particular fondness for ‘woody’ and so I’m very pleased to have spotted at least 3 families nesting with us this year. They are real characters and it is fun watching the parents bring up their young. They are fairly nervous birds and don’t seem to like close human attention but with patience its surprising how much you can observe.

To identify the family members look for red markings on the head and neck; the male (3rd picture) has a red nape to his neck, whilst the female (2nd picture, below) has no red on head or neck, the juveniles (top picture) have a red cap, the young male’s often being brighter & larger than his sister’s.

Greater Spotted Woodpecker - Female Image Details:Focal Length 1400mm

Female – note no red head markings

Click image for a larger view …

They are resident all the year around across much of Europe and eat insects, seeds & nuts. They are also rumoured to take small birds eggs / chicks, if times are hard. Happily our families seem to feast on the peanuts that we put out, the many conifer cones in the woodland and of course our bountiful insect harvest!

They are well known for their rapid drumming on hollow trunks, which can be heard from quite a distance and have a specially adapted beak & skull to avoid injuring themselves whilst drumming. It seems that wooden electricity poles are especially good for drumming on, as many a frustrated engineer will tell you :-) Their tongue is long and sticky enabling the recovery of insects from holes in wood or even choice peanut fragments from a feeder.

Greater Spotted Woodpecker - male Image Details:

Focal Length 400mm

Male – note red nape

Click image for a larger view …

For more on that tongue, can you make it out in the picture below? The barbs are just visible pushing the peanut chip up against the juvenile’s top beak. This picture isn’t ideal & I’m working on taking a sharper one but it’ll have to do for now.

Woodpecker Tongue

 

To find out more about woodpeckers, try following some of these links:

Wiki article on the Greater Spotted Woodpecker

Birds of Britain article on same

or try these two sources for more general Woodpecker articles Britannica or How stuff works.

 

Oh and if you like my images don’t forget that many are available as prints from my business sites; in fact I hope to have a woodpecker poster out this autumn (08).

The Ghost Swift

Posted in Moths and Butterflys,Nature and Environment by AnnMarie @ Jun 30, 2008

This beautiful moth is extremely well named, on summer nights you might see the male dancing its ghostly dance across your garden. He is trying to attract a mate with his rapidly moving wing beats whilst hovering & darting just above the vegetation.

Ghost Swift

The scientific name for this moth is Hepialus humuli. The female is more yellowy than the male (who is in both of my pictures here).

Ghost Swift

I used off camera flash to help me with these shots, manual focusing in the near dark was the trickiest problem.

For a different view, why not take a look at the wildlife trust’s page.

Goosey Geese at Ynys Hir

Posted in Nature and Environment,Photography by AnnMarie @ Feb 15, 2008

We took a quick trip to our local RSPB reserve this week. Just a quick afternoon trip but very enjoyable none the less, if you’re in the area please do consider visiting this fantastic resource. You can find out more by clicking here.

Whilst there are many different species to spot, from squirrels & songbirds to a variety of birds of prey, it was the geese that caught my attention on this beautiful February afternoon.

_MG_0323-12Feb08-Edit

From this lovely Greylag Goose (above) who was fairly determined to stand with its back to me until it heard me rustle in the reeds, up popped its head whilst I froze for fear of scaring it off; but this picture was the result :-) To the goose that I shared my school playing grounds with (see below):

_MG_0301-12Feb08-Edit

Yes the Canada Goose and this one decided to have a lovely stretch of the wings in the evening sunshine. There really wasn’t a goose shortage today. As the sun set, we were right down on the river estuary the river waters turning a fiery orange as the sun met the horizon.

_MG_0327-12Feb08

Swans, Mallard, Pochard and more, came flighting in as dusk fell; but true to the day it was geese who dominated the evening too, with hundreds coming in from the neighbouring area.

_MG_0374-12Feb08

Ynys Hir, definitely somewhere to spend some more time.

Garden Birds – Up Close

Posted in Birds,Photography by AnnMarie @ Feb 6, 2008

The last few days I’ve been testing some new photography equipment. The weather has been fairly damp & murky, until today, which was beautiful. Anyway I decided that one of my test subjects should be some of the birds in and around the garden / hedgerows. Amongst others that includes:

- Chaffinch- Brambling

- Blue Tit

- Greater Spotted Woodpecker

- Siskin- Robin

- Dunnock

- Buzzard (soaring high above)

-
Here are a few images, be sure to click the link at the bottom to view the interactive image of a Dunnock:

_MG_0013  _MG_0047
_MG_0098 _MG_8621

-

As I said today was a distinct improvement and I could do some winter hedgerow shots:

_MG_0126 _MG_0089
_MG_0116 _MG_8612

-

Have you ever looked really closely at a small bird? Their fine feathers and exquisite colours are so beautiful. Click here for high resolution image of a Dunnock. The image is scrollable & zoomable and having been taken at a focal length of 1000mm, there’s quite a bit of detail (more detail downloaded each time you zoom, so give it a little while).

I’m really looking forward to spring now! Lots of photography opportunities.

BTW: Shameless plug here – if you’d like to purchase prints of my images, many are available for direct purchase from my business site: Celestial Galleries

Autumn – Signs & Hues

Posted in Education,Nature and Environment,Photography by AnnMarie @ Oct 30, 2007

Popped out to Dolgellau last week, late afternoon was dull cloudy & wet, yet within a little over an hour, a beautiful but fleeting sunset developed.

_MG_8103-2-ld-2c

Typical changeable autumn conditions for us. The picture above is of the old bridge over the Afon Mawddach, between Dolgellau & Llanelltyd. A  fly fisherman stands in front of the bridge enjoying the evening. These days the bridge is closed to motorised traffic and it is very peaceful despite being only just off the A470.

_MG_8301

At home in Aberllefenni, the autumn colours have been richening up. This image shows some of our horses enjoying the autumn grass. The paddock is bordered by deciduous woodland, mainly oak, ash and hazel. Beyond that, the mountain is planted with spruce, larch and pine. All the trees have their own distinctive autumn shades, with the spruce & pine remaining green.

_MG_8313

Even some of the horses are trying to blend in!

Have you ever wondered why the leaves change colour in autumn? It’s due to the range of pigments that are in the leaves. Chlorophyll is the main pigment that plants use to help them harness sunlight to produce carbohydrates. Chlorophyll appears green, it isn’t very stable though and plants have to continually synthesise it. It’s production falls when temperature & daylight levels drop.  This happens in autumn allowing other pigments to become the dominant leaf colouring agents.

_MG_8324

The beech trees are a particular show at the moment.

So what are these other pigments? Carotenoids are a group of yellowy coloured pigments and they are significantly more stable than chlorophyll. Thus some leaves turn yellow as the green fades. What about the reds, I hear you call. Well they are due to a family of pigments called anthocyanins. As the tree prepares for leaf senescence (dropping of its leaves) the amount of sugar in a leaf may build. Depending upon temperature & light levels, this can trigger flavonoids to be converted to anthocyanins. The exact resulting colour tone depends upon the pH (acidity) of the plant sap.

_MG_8317

But eventually they’ll all end up on the floor.

Finally a membrane between leaf stem & tree is completed, it now separates the leaves from the tree. As the membrane joint withers the leaves fall from the tree and carpet the floor.

Any how, it all produces a marvelous sight for us to enjoy.

Saving the Unicorn

Posted in General,Horses,Nature and Environment by AnnMarie @ Oct 28, 2007

It’s a dark, wet & windy night outside tonight; last few nights too. No astrophotography then, and I’m almost up to date with my standard photo processing – that means I’ve had a little time to indulge myself in a hobby that I keep meaning to learn but never get around too – computer aided 3D artwork. I had in mind a beautiful woman who comes to save a stranded Unicorn. The image was to be set in daylight with a rainbow background; I did that but then I changed it (fickle aren’t I). This is what I’ve ended up with …

Night-Friends  Click image for larger view …

I  settled on simply calling it “Friends” because that’s what we should be with creatures of all kinds. It’s not a complex image but then I’m only a beginner at this. The Lady represents the spirit of Mother Nature that we all have, somewhere within us.

I hope you enjoy the image. Maybe I’ll get chance this winter to practice my artwork some more; if so I’ll post some here.

Look Closely & Imagine

Posted in Education,Nature and Environment,Photography by AnnMarie @ Aug 26, 2007

I really enjoy macro photography; it can show us worlds that we don’t usually notice. What’s life like for other creatures? A beautiful flower in our garden might be a fast food bar or a solarium for a small insect. Take this afternoon for example, I was enjoying one of my favourite roses.

It has beautiful shades, sometimes looking purple & sometimes blue. The scent is wonderful but you always have to check before smelling it closely, let’s look why …

Inside the flower not only is there a veritable feast of pollen & nectar but it’s also a perfect sun trap. This small fly has found heaven! Hmm I don’t want him up my nose; perhaps I’ll look at a different flower. Nearby is a yellow rambling rose that also has a scent to enjoy but I’m not alone there either. There’s a rather nice hoverfly enjoying the flowers, in fact he’s quite polite and poses for me to take his portrait.

They have the most fantastic compound eyes (click on the image for a closer look) but I don’t suppose that will help him approve of his portrait photo – it’s not sweet & sticky enough.

Quartz – Rock of Ages

Posted in General,Nature and Environment by antamuk @ Jul 27, 2007

Yes yes I know poor title choice, I am a Def Leppard fan after all. Anyway this post is really about quartz the rock, you know put a voltage across it and it pulses regularly to keep your wrist watch nice & accurate. Well I’ve always had a thing for it. I used to collect it as a child and Tamsin appears to have inherited the trait.

Polished & unpolished quartz

We have a tumble polisher (Jane’s) and that can produce beautiful glossy specimens. The picture above shows you various samples that we have polished plus a few lumps of ‘raw’ milky quartz from around the farm. You can clearly see different structural qualities within the stones. They are attractive in their own right but can also be used for making your own jewelry with. Manchester Minerals are a great place to find out more info & to buy supplies from.

Quartz is crystalline Silicon Dioxide and is the most common mineral on Earth’s surface. It occurs naturally in many different colours, as you can see from my picture above. It is a fairly hard mineral, rated at hardness 7 on Mohs scale.

Some of the varieties are listed below:

  • Amethyst (purple)
  • Rose Quartz (pink)
  • Rock Crystal (transparent)
  • Milky quartz (partially opaque white)
  • Citrine (yellow)
