Mont Blanc and Alps from the Pays de Gex

Mont Blanc and Alps from the Pays de Gex


Spring almost came to the Pays de Gex recently, and our morning walks were more pleasant for a while. It’s cold again now, but for a few days it was even warm enough to stop and take a few photos, here’s a selection for you.

deer jawbone

The most unusual thing we’ve found recently has to be this lower jawbone, presumably of a deer. It was lying right in the middle of the snow-covered path, with no clue of how it got there. It must be rather old, I guess, it looks like it’s been around for a while.

There are a lot of deer around here, so I guess it’s not surprising to come across a bone or two from time to time, but this is the first for us. Some people are luck enough to find the occasional antler instead of a jaw, but I guess we have to start somewhere.

Then there’s this beautifully-carved fallen branch, with all these intricate markings in the wood where the bark has been stripped away. I would have guessed that this was beetle-damage from that alone, but thanks to Seabrook at The Marvellous in Nature, I know rather more about them.

The deeper grooves are where the adults tunnel along the bark, the female laying eggs as she goes.

The smaller grooves are where the young eat their way along the tree, somehow apparently managing to avoid their siblings as they do so. This particular branch seems to have been very popular, it’s covered in tunnels.

Strangely enough, it’s not just Seabrooke writing about bark-beetles, her mom has just posted about them at Willow House Chronicles. Seems like an interesting family…

fire bug <em>Pyrrhocoris Apterus</em>

Closer to home, there’s a large tree near where we live which harbours a good collection of fire bugs, Pyrrhocoris Apterus. They were there just before winter in the same place, sunning themselves in the last rays of autumn. I guess they must have over-wintered under the bark, there’s certainly room for all of them in the crevices of this old tree.

Not only are they colourful, they have very distinctive markings on their backs. It looks uncannily like a face, reminding me in particular of an African mask. You can see that clearly in the close-up.

Finally, one thing that often turns up on our morning walks as the snow melts is these plastic bags, the sort used to hold fat-balls for feeding the birds. It’s great that so many people put them out, but I’m a little concerned that small birds or animals could get entangled in them.

If you put out fat-balls in these bags, please consider threading a piece of string through the mesh and tying it off somewhere, to prevent the empty bag from blowing away. Then you can easily dispose of the bags without them ending up in the environment!

James Camerons’ new science-fantasy film, ‘Avatar’, starring Sigourney Weaver, is doing the rounds at the box office in Geneva. I saw it recently, and I have to say, it’s an amazing film. See it in 3D if you can, it’s worth it.

Without giving away too much of the story, I can tell you that it’s set in the future where humans travel to a planet called ‘Pandora’ to mine a valuable mineral from under the feet of the indigenous natives. The natives don’t want to give up their lands, of course. The humans attack them with the usual military hardware, and the natives fight back with bows and arrows. Nothing particularly new there, the plot has a familiar ring to it.

Nonetheless, Avatar stands out from the crowd. James Cameron is not known for thinking small, and the visual effects are quite stunning. The landscapes are exquisite, and the plants and animals are beautiful. Bio-luminescent plants glow underfoot where people walk at night. The whole thing is put together superbly, with a great deal of attention to detail.

The natives (“Na’vi”) are tall and elegant, and more than a little elfin in appearance. They live in harmony with their world, respectful of the living things they share it with. Taking no more than they need to survive, they deplore the humans’ lack of balance with nature. When the tribal-chief’s daughter rescues one of the humans from a sticky situation (I told you the plot was familiar), she chastises him, telling him “you do not see”. Like so many of us, he considers himself to be separate from the web of life around him, not a part of it, so he is blind to the real beauty of it all.

It seems that message has struck a chord with many of us, and some people get depressed after seeing Avatar. They envy the Na’vi their lifestyle, and are not happy to think that they can never live that way, nor live in such a beautiful place as Pandora.

I guess I can understand that, but I don’t agree with it. The Pandora that James Cameron has created is indeed very beautiful, and the Na’vi have a great way of life. Sure, they occasionally have to dodge things with teeth the size of their heads, but apart from that, they seem to have it made. But while Pandora might be a nice place to visit, I don’t think I would want to live there. Planet Earth is my home, and I’m happy here.

It’s true that most of us cannot claim to live in harmony with nature. Probably only a few of us would want to go as far as the Na’vi, but we can probably do better than we do today. All we need to do is to go out there and start looking around, the natural world is just waiting to be found.

You don’t have to go on safari either, nor to a tropical island. You can go to your nearest beach, lake, river or woodland, and take a good look around you. You can go down to the bottom of your garden, or to the nearest park. Nature is at home in all sorts of places.

I’ve seen blue-tits working hard to bring food to their young in the nest they built in the shutters of my apartment window. I’ve even been lucky enough to see one of those chicks make its’ first flight, leaving the nest. I’ve seen baby birds clambering to hitch a ride on their mothers’ back, rather than expend the effort to swim alongside her. I’ve seen a pigeon raise a family in an empty flower-pot on my balcony. I’ve seen all sorts of pretty insects – caterpillars, butterflies, crickets, bees and beetles – in the plants I’ve grown on my terrace. Nothing unique or exotic, but all beautiful just the same.

It’s not just birds or insects either. I’ve had squirrels come up to me in Hyde Park, looking to see what I had in my hand. I’ve seen a hedgehog on my terrace, and frogs in my Mums’ garden. There are deer and foxes in the Jura that we sometimes see on our walks, or even from the comfort of our home. After a fresh fall of snow the sheer number of animal tracks has to be seen to be believed, there’s so many of them. We saw a weasel not long ago, and I’ve seen chamois and marmots in the Alps.

I’m no expert at finding these animals, I just go out and look. I don’t see them every day, but that makes it all the more precious when I do.

If you live in the concrete jungle and don’t have any countryside within reach, try visiting your nearest park. If there’s grass, trees, and flowers then there will be birds, bees, and other insects. Take some bird-seed and you might be able to tempt the birds to come close to you. Give them time to get used to you and they may even perch on your hand. Come evening, you may be lucky enough to see bats flying around too. If there’s a pond then there may be frogs or dragonflies hidden among the reeds.

If you don’t have time to go somewhere, you can put a birdfeeder in your garden, on your balcony, or just mounted on the wall outside your window. Birds will find it, and you can enjoy them from the comfort of your own home. You can really see their characters emerging when you see how they behave around a feeder, it’s fun to watch.

If you’re not sure where to start looking, there are plenty of good sources of information. Your local library or tourist office can tell you about nature-groups, natural attractions, or forthcoming nature-related events in your area. If you know someone more experienced, ask them to show you where to look. There are several good TV programmes too, such as Springwatch in the UK. Or you could search the web for nature-bloggers in your neck of the woods, and ask them a few questions. They’ll be sure to help you if they can.

I’ve not seen anything as big or colourful as the creatures that the Na’vi encounter on Pandora, but fair’s fair, I’ve not met anything that tried to eat me, either. If you take the time to go looking for it, nature is never far away. Go take a look, you’ll see.

Just a few days ago, I commented over at The Marvellous in Nature that we didn’t have enough snow yet for snow-shoeing. Well that has all changed! We now have several centimetres, or quite a few inches, depending on which you prefer.

The photo above was from our morning walk last Friday. The stream below on the right was taken then too. Plenty of snow there, as you can see. Later in the day we had more snow, the picture on the left being taken from the warmth and comfort of our living room.

Even before the snow came, it’s been very cold here, so obviously there are far less insects about now, but there are still a few surprises here and there. Some days ago I looked up from my laptop to see this lacewing on the outside of the window. As far as I know, they should all be hibernating now. Maybe he had heard about the bug-hotel I made last month and was going to check out the accomodation?

He’s not the only lacewing we’ve seen lately, one has decided to move in with us for the winter. He now spends his time in the spare room, which we keep unheated for my cacti.

We’ve named him Edgar, the fly who came in from the cold. Edgar has spent the last 2 or 3 days on the window-sill, which is not a particularly safe place for him to be, so I’ve moved him into a small box of shredded paper. I have no idea if he manages to find food, or if he needs any now, he doesn’t move far at all it seems. If anyone has suggestions on how to look after him and help him survive the winter, please let me know!

Then of course there’s our feathered friends. We have many birds sheltering in the eaves, and they are quite happy to avail themselves of the food we put out for them. We’ve been investigated by magpies a few times too, but they seem too shy to stay when they see us through the window. Hopefully they’ll learn to trust us and stay a little longer, they’re so beautiful.

The birds don’t seem to bother with the water much, which I think is pretty ungrateful of them considering the effort it takes to replace it every time it freezes. Still, I guess they know what they need. As long as they keep coming for the food, we will keep putting it out for them!

Wherever you are, whichever creatures you have sharing your Christmas, indoors or out, I wish you, and them, a merry Christmas.

lacewing

lacewing

Winter is approaching, and change is in the air. We’re wrapping up warmer these days, and we’re not the only ones. Insects, such as this lacewing, are looking for a safe place to spend the winter. This year, I’m trying to help them.

There are lots of places on the web where you can get good information about the type of home that you can provide for insects for the winter. They range from simple things like a pile of leaves in a wire cage to more elaborate and attractive DIY projects like the one at Herbs and Dragonflies. Other sites have more detailed information, such as the Paignton Home Garden & Allotment Society, or the Cheshire Wildlife Trust. For the ultimate in accomodation for garden wildlife, take a look at the invertebrate habitat they designed as part of their exhibit at the 2005 RHS Tatton Park Flower Show.

I wasn’t nearly as ambitious as that, maybe next year, who knows! I put together a simple bug-home from a plastic container, a few pieces of bamboo, and a bit of string. I started by sawing off the bamboo into sections, just behind the knuckles so that each section is closed at one end. Many of the sections were still filled with pith, I used a long drill-bit to clean them out.

Then I made four holes in the plastic container, two at the top, two at the bottom. The holes are spaced about a quarter of the way around the container, and the pairs of holes line up along the axis of the container. Oh just look at the picture, you’ll get the idea!

I threaded two pieces of string, one in and out of the top pair of holes, one in and out of the bottom. Then I stacked the bamboo in the container, with the closed ends inside of course! Pack the bamboo in tight, so that it holds itself firmly.

I made sure that the string was looped around the bamboo inside the container, so that when I pull it tight it will hold the bamboo tighter together. Otherwise, the string might just tear through the plastic over time, and that would not be good.

Then I simply tied it to our fence. It’s deliberately placed on a slight downward angle, to prevent water running down into the bamboo and drowning any unsuspecting occupants. It’s also close to our wall, and facing it, so that it gets protection from direct rain and winds.

My only question is, how will I know if there’s anyone living in there? Any ideas?

A Walk to Divonne

Summer has gone, Autumn is here. Trees are shedding leaves, flowers are fading fast, and the house-martins left a while ago. But as Jane points out in Urban Extension, sometimes there are new things to see in Autumn. I haven’t seen her special bee yet, though I’m keeping an eye on the ivy near my home. However, I have seen lots of other interesting things recently. Here’s a selection taken from a walk through the country lanes near Divonne two weeks ago.

At the top is a Pale Tussock moth caterpillar (Calliteara pudibunda). This guy was crossing the road, intent on going somewhere. I’ve never seen one of these before, but this must be the season for them, because we found another further on. They’re rather striking, the tufts make them look like a toothbrush!

There are still some flowers around, and yes, there are insects keen to visit them. This bee and the fly were just two of the more co-operative characters we encountered.

Autumn is, of course, a good time for fungi. I don’t know the names of any of these, maybe Winter Woman knows, she’s keen on fungi.

Further on, there were plenty of other insects crossing the road. On the left is a forest bug (Pentatoma rufipes). On the right is a dragonfly, a ruddy darter (Sympetrum sanguineum), who very obligingly stayed still long enough for me to take his photograph. That doesn’t happen often.

All the insects shown so far were actually on the road, for reasons only they know. This great green bush cricket (Tettigonia viridissima) was no exception. Dweezeljazz almost stepped on it, but she saw it just in time. It then hopped into the grass at the side of the road, making it much more photogenic. The Rhopalus subrufus on the right was on a wall in Divonne. Not exactly its native habitat, but well-placed for the shadow to show details you can’t see on the actual insect, so I’m quite happy with this shot.

It’s not just insects out and about in the Autumn sunshine. I was rather lucky to get a shot of the lizard before he dived under cover. The frog did dive for cover, but then drifted out to take a look, and stayed still for the photos. Very kind of him!

There’s still plenty of action on the plant front too. There are many flowers to be seen, even if they are mostly small and unspectacular by comparison with the competition in summer. These blue flowers are some of the largest still around. But even without flowers, there are some very pretty plants, like the Verbascum rosette. Elsewhere in our contryside, there are verbascum plants in their second year which still have some flowers left on them, bright against the brown of dying vegetation. Meanwhile, these first-year rosettes look very pretty in their own right.

Then there’s this old apple tree, which has sufferred badly in the late summer storms. Despite this, it’s still doing a good job of maturing its fruit, you can see there’s no shortage of them still on the tree. It’s clearly not giving up without a fight.
