OK, where’s the food

The snow is melting fast outside now, there’s only a few piles of mush left on the terrace. The last snowfall here was almost a week ago, and that was a scant few flakes, just enough to cover the ground thinly.

It may have been a light snowfall, but it was enough to show me that little feet had been walking around just outside before I got up that morning.

It’s not just one or two footprints either, there seems to have been quite a gathering around the food. I hope nobody got trampled in the crush!

We have bird-food on our garden wall, but in the coldest weather the robins were getting very territorial about it, spending more time fighting than eating. That’s why we put more food near our patio doors, far away from the wall. This kept the robins far enough apart that they actually found time to eat instead of fight.

The food near our patio doors is quite popular, despite being close to the house. It’s interesting to see how different birds approach it. Sparrows just come right up and start munching. They spend a lot of time in our eaves, so they’re well accustomed to us and our comings and goings, and show no fear. Other birds are more cautious, such as this chaffinch.

This is the only chaffinch I’ve seen visiting our garden so far, though we see many on our morning walks. This one did what many other birds have done, he landed a little further out and took a good look before coming closer.

He’s clearly spotted me, and that sideways look is him measuring me up, deciding if I’m going to make trouble for him or not. Eventually, it seems he decides I’m not a threat, and he turns his attention to more important things, the food!

Blue-tits and great-tits show a similar caution. They land nearby, take a good look round, then hop up to the food, take something (typically a peanut) and fly off to deal with it somewhere else. They seem to get more comfortable with time, the first visits were rather cautious, and sometimes they would fly off without feeding. Now they are more at ease, and will even continue to feed if we go out on the terrace.

Robins will sit by the food for a long time, as if they’re staking a claim to it. Even in the coldest of the recent weather they would sit there, guarding the food. They don’t often chase off sparrows or tits, but if another robin appears within a few feet, it’s instant action. Those birds have attitude!

Now that the local birds have become accustomed to us, we see a steady stream of them. Yesterday and today we saw a willow tit, one that I’ve never seen before. It seems word is getting around that there’s a new place to eat for the birds, and we’re glad of it. Fortunately, lots of people feed the birds around here, so winter is not as difficult for them as it could otherwise be. I’m glad of that.

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.

Bird feeders

The recent spell of freezing weather is coming to an end, but not before it dropped a foot of snow on our terrace. Birds have a hard time in such cold weather, in fact it amazes me that they manage to survive at all. There’s a very interesting post over at Willow House Chronicles about how birds survive cold temperatures if you’d like to know more about how they manage it.
We’ve been putting out food for the birds again this winter, normally just clearing the snow and placing it on the wall. That seems to suit birds like the robin, above, and our resident sparrows, but it can easily be covered by snow or washed away by rain, so this year we’ve also added some proper bird-feeders.

So many of the feeders in garden centres seem impractical and decorative, but after some shopping around I finally found this very practical feeder shown on the right. It’s not particularly cheap, but it does keep the seed clean and dry against all weathers, which has got to be a good thing. I don’t have anywhere obvious to hang such a feeder, so I took the low-tech solution. I found a suitable branch on our morning walks, tied it to the railings of the fence, and hung the feeder from that.

We also got two suet-feeders, and then spent some time looking for suet in the shops we frequent. Our favourite bio-store, Satoriz, didn’t have any, but they did have peanut butter, so I used that instead. I’m sure I could have found suet if I had looked around enough, but since the peanut butter is organic and any suet I find would not be, I prefer to use the peanut butter. I buy organic food for myself because I don’t want to eat pesticides, and I don’t see why wild birds should do so either.
I mixed some bird seed in with the peanut butter, quite a lot in fact, put it in the suet feeders, and hung them from another stick I’d picked up on our morning walks.

For a bit more variety, I tied some millet to the fence too, and I continue to put food loose on the wall for those that prefer it there. I also have a thistle-seed sack-feeder for finches, but no seed to put in it yet. Soon, I hope!

Now the restaurant is open, all we need are customers. First to find us was our robin, of course. You can see him here checking out the feeder during the day of heaviest snowfall. Like so many birds, he shows a great deal of curiosity at anything that changes in his environment. Having decided that it’s safe, he continues to be our most regular visitor.

A couple of days later and a few more birds had found us. The great-tits seem to like the peanut butter, while blue-tits like the tall feeder. We have even been visited by a magpie, who comes a few times daily, takes 3 or 4 peanuts in one go, and flies off to enjoy them somewhere else. I expect that as time goes by we will get more visitors, and hopefully more species too – I know there are woodpeckers nearby.
The magpie is our largest visitor so far, and unless the chickens down the road escape from their coup we’re not likely to get anything much bigger than them. Some people do get larger birds visiting them, such as our friend Shannon Ryan. Take a look at what she gets visiting her bird feeders. They must take quite a bit of feeding!

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.

Gardening over for the year…?

Sunday, November 8th, 2009
plant tubs, covered for the winter

plant tubs, covered for the winter

The garden is finished for the year, which is a shame because it’s been a lot of fun. We had the last of our lettuce just a few days ago. It was surviving nicely due to the lack of frost, though it was hardly growing anymore, it’s too cold now. I’m surprised it has lasted so well, I wish I’d planted more towards the end of the summer!

Today I ‘officially’ closed the garden by covering the big plant tubs with their water-trays, to avoid having the winter rains leech out all the nutrients before the next growing season. I’d never really paid much attention to how soil in pots gets depleted of its nutrients before, but that was brought home to me this year. The white tub that I have had for many years grew tiny sunflowers compared to those with new soil, which were three or four times bigger. Shame on me, I should have known better.

I don’t want to use chemical fertilisers, I don’t want to replace the soil in the pots, and I don’t think I can realistically put a compost heap on my terrace, so I’m trying something different. I’m digging small, deep holes in the soil, and burying vegetable peelings in them. Hopefully, over winter, they will rot down enough to feed the soil without also rotting next years plants. Maybe it will work, maybe not, we’ll see!

Our garden has been quite productive, and we’ve enjoyed the produce from it. A recent study claims that organic food is no healthier than normal food, but that study completely ignored the use of pesticides in conventional agriculture. I’ve read enough to convince me that pesticide-free veggies are a good thing. Of course, there are other benefits to growing your own vegetables, such as reducing food-miles.

Food-miles are a measure of the amount of fuel needed to transport food from the farm to your plate. That fuel all contributes to climate-change by emitting greenhouse-gasses, so getting your food locally means less global warming. You can’t get more local than your own garden, so growing your own food is good for the planet too!

On a larger scale, organic farming is also beneficial in the fight against climate change in other ways. Organic farming feeds the soil, not the plant, and doing so means that the soil will absorb and hold more carbon dioxide from the atmosphere than chemical-intensive methods. The Carbon Farmers of America have taken this one step further, deliberately adopting farming techniques to optimise carbon sequestration, and making farms more productive in the process. The story of the farms of “Yobarnie” and “Nevallan”, in Australia, is quite an eye-opening account of how well such techniques work.

So your organic garden may be good for the climate, as well as providing good food. I could have squeezed a few more vegetables out of our garden this year, but I’m glad I left some space for sunflowers instead. Apart from being pretty in their own right, they’ve been feeding the bees all summer, and now feed the birds, long after nearly everything else out there has finished. If you look closely at the photo below you’ll see there are 6 goldfinches, quite a sight!

Nor is it just goldfinches, we’ve had great-tits too. As you can see, they’re not timid about getting their share, this one was quite happy to push in while the goldfinches were feeding. He’s more agile than the goldfinches, so manages to get his way.

Other birds have benefited from both the goldfinches and the great tits dropping seeds on the ground. Black Redstarts and sparrows often forage around the pots while the other birds are doing their stuff. Sparrows may be plain compared to other birds, but they’re still fun to watch. Here’s 3 of them looking on while a fourth is dipping into the bowl of water we put out for them. You can’t easily tell, but he was taking a bath at the time.

Finally, although the garden outdoors is finished for the year, we’re still growing something! Dweezeljazz has got the bug now, and is growing fresh shoots of all sorts for our salads. They’re very easy to grow, using a neat little gadget from Satoriz, and make a welcome addition to our meals. Thank you, Dweezeljazz.

Goldfinches

Saturday, October 3rd, 2009

In my last post, I showed a picture of a goldfinch feeding on one of our sunflowers. That was the only photo I had at the time, and I was hoping to get something better than that. I didn’t have long to wait, these pictures were taken just a day or two later!

According to the RSPB, goldfinches can be seen all year round. Where I live, they seem to find somewhere else to go in summer, we haven’t seen them since Spring. Before that, we would regularly see a group of a dozen or so birds feeding on the teasels not far from our window.

We shall be putting out seed for them through the winter. Any bird, especially one that colourful, is welcome in our garden.

My little organic terrace-garden has been rather successful this year, and the produce has been very welcome at our table. We’re not the only ones to appreciate it, naturally, there are plenty of critters who have helped themselves throughout the summer. That’s OK with me, I’m happy to share to some extent, providing they don’t eat everything.

beetroot leaf eaten by leaf miners

beetroot leaf eaten by leaf miners

One common form of damage has been beetroot leaves eaten out from the inside by leaf-miners. There was a lot of this in early summer in particular, and I had little choice but to remove the affected parts of the leaves and throw them away. Otherwise I would have had very few leaves left on some of my plants! Apparently, some plants have evolved patterns of markings that look similar to the damage caused by leaf-miners, which protects them because the leaf-miners prefer unoccupied leaves in which to lay their eggs. Maybe I’ll ask Dweezeljazz to go out and paint the leaves for me next year, that sounds like a job for an artist!

There have been any number of butterflies hovering around the garden, even well before there were any flowers in evidence. They must have had something else in mind and yes, sure enough, I have found lots of eggs hidden on the leaves. Some were quite hard to spot, among the beetroot in particular. Some were easier, like the yellow eggs on the nasturtium leaves.

Butterfly eggs, of course, hatch into caterpillars, and I have found quite a number through the summer. On the left is a ‘Small White’ (Pieris rapae), this one was just running around the rim of the pot like he was desperate to find the end of it. I don’t know what the one on the right is called. Below them is, I think, the caterpillar of a Garden Tiger moth (Arctia caja). Apparently, Tiger Moth numbers have been decimated in the last 30 years, due largely to excessive use of pesticides. Like many other small creatures, they are now in need of protection in the UK. This one was running across our living room floor at high speed, heading for the stairs, looking for a place to pupate. He was safely redirected to the great outdoors!

There have been a number of other insects, such as this bright green beetle (probably a Chrysolina species), and the two crickets below.

The one on the right is Roesel’s bush cricket, (Metrioptera roeselii), and this poor specimen has lost one of his hind legs. Despite this, he was quite agile, climbing easily, and was able to manage a decent hop when I picked him up and released him in the nearby bushes.

It’s not just insects that visit our garden. After being absent this summer, the goldfinches are back, this one investigating the sunflower heads for seeds. Well, that’s why I planted them! I know it’s not a good photograph, but it’s the only one of a goldfinch that I have at the moment, so it will have to do. Hopefully I’ll get better photos later.

Although not closely related to the American goldfinch, it does share its taste for sunflower seeds!

hedgehog

Finally, late one night a few weeks ago, we found this hedgehog doing the rounds on our terrace. I don’t think he found anything edible, but he’s welcome to come back anytime. Again, not a perfect photo, but we don’t like to use flash on animals, especially nocturnal ones. He wasn’t hanging around for us to get many shots, this is the only one we got of him too!

 

I haven’t any photos of all the bees, butterflies and wasps that have visited my garden too. Maybe next year. It’s amazing how much variety you can get visiting just a few pots of plants.

Walking in Geneva with DweezelJazz recently, near to Carouge, we were surprised to find these House Martins nesting under a ledge on an apartment block. It took me a moment to realise that these were no ordinary nests, constructed from mud. Oh no, these are made from steel!

Now I do know that birds can use tools, and that they can invent them as well. There’s Betty, a New Caledonian Crow, who is famous for having figured out how to bend wire into hooks to retrieve food. You can see that in a youtube video of her exploits.

Then there’s Jasmine, our African Grey, who was also very adept at undoing nuts and bolts. She even tried to re-assemble them after taking them apart, and came very close to doing so more than once. However, unless these House Martins have learned how to use power-tools, I rather suspect these nests were provided for them by some kind soul. Whoever it was, in my opinion, you deserve a medal.

The birds clearly approve too, these nests are very well-used. In the few minutes we spent watching them, most of them had someone come or go at least once. The shelf underneath the nests is also a good idea, people passing by can do so without having to worry about what might fall on them.

Good for you, Geneva!

World Oceans Day, June 8th

Saturday, June 6th, 2009

The Aegean

The Aegean


Next Monday, June 8th, is World Oceans Day. At the risk of turning this blog into a diary of global eco-events, I’d like to draw your attention to it.

The idea to have a world-day for the oceans came in 1992 from Canada, at the Earth Summit in Rio de Janeiro. It’s been celebrated every year since then, but this year marks the first time it has official U.N. recognition. Henceforth, World Oceans Day will be celebrated on June 8th, every year.

You might think that since I live near Geneva, about as far away from the sea as it is possible to get in Western Europe, I would not have much to say about the sea. If you think that, you must be new to this blog (welcome!), the sea is one thing I can talk about for hours. I grew up in England, closer to the coast than most people there. Nobody in England is more than 70 miles from the sea, I grew up much closer than that, about one mile away from the shore, on an island, no less. I spent many a childhood summer day freezing in the cold water, picking my way over the stony beaches, trying to see what I could through the opaque grey-green waters of the north Kent coast (not much, as it happens). I collected foraminifera (tiny shells, less than 1 mm across) and looked at them under a microscope. I remember the first time I saw sea-anemones, on the beaches of Jersey on a family holiday. I’ve seen octopus and nudibranchs on crowded Greek beaches, and sharks and dolphins in the Maldives. Oh yes, I can safely say I love the sea.

The oceans are huge. They cover almost three-quarters of the surface of the earth, and something like three fifths of the earth is over a mile below the surface of the sea. There is an awful lot of seawater out there. So why do we need a world-day event to draw attention to the oceans? Well, as it turns out, the seas and oceans of the world are not in good shape, and it’s our fault, again. You can find out more about the threats to the oceans on the Marine Conservation Society website, here are a few of the highlights.

Everyone knows about global warming, and the melting of the polar ice-caps. That’s bad news for penguins and polar bears, but also for people. A large fraction of humanity lives near the coast, making a substantial part of their living from what they can haul out of the sea. Rising seas and warming waters will change that. Not only will islands and low-lying regions be lost under the waves, the ecosystems at the coastal fringes will suffer too. Coral reefs, for example, provide living space and nurseries for a great many species, and are essential to the marine environment. Even creatures that don’t live on or in them directly often depend on the animals that do. Excessively warm water leads to ‘coral bleaching’, which can kill it if the water stays warm for long enough. Bleaching events are more common than they used to be, and are predicted to become much worse over time. Despite some research showing that some corals may adapt to warmer waters, there is strong reason to believe that most corals will be killed by warm seas by the end of this century unless we make big cuts in our emissions of greenhouse gasses. Scientists are working to find ways to help coral survive, but they’re racing against the clock.

Coral

Coral

Globally, there’s an even bigger threat, ocean-acidification. The oceans absorb a great deal of the excess carbon dioxide that we are pumping into the atmosphere, and this is slowly turning the seas more acidic. This slows coral growth because it is harder for the coral to form its chalky skeleton. Other creatures, many of which are right at the bottom of the marine food chain, will suffer the same fate. Acidification of the oceans is a global problem by its very nature. It will affect reefs and other ecosystems worldwide, not just those near to cities and industries.

Overfishing is another major problem for the oceans. By depleting stocks of even a few species, we change the way entire ecosystems behave, often seriously. Tuna have been fished almost to extinction in the Mediterranean sea, and there is little sign that common sense will prevail to reduce the pressure on them. Tuna are predators, high up in the food chain. When you remove top predators, often the result is that a few species lower down the food-chain start to dominate, out-competing other creatures. The ecosystem becomes unbalanced, and may change its nature completely. It may not be enough to simply stop hunting the predators, the ecosystem may no longer be able to recover on its own.

Floating garbage is another serious problem. On the tiny atoll of Midway in the Pacific ocean, albatross often mistake floating plastic garbage for food, which they then feed to their chicks. That kills many of them, not surprisingly. Albatross aren’t meant to digest golf-tees, toothbrushes, and lego blocks.

Even the efforts we go to to protect the oceans and their inhabitants can often be misguided. I’m sure we’ve all heard of dolphin-safe tuna, it even got a mention in Lethal Weapon 2, released some 20 years ago. I’m fond of dolphins, like many people, but I was shocked to learn about just how much damage dolphin-safe tuna-fishing can do. The methods used to catch tuna without harming dolphins have a much higher rate of bycatch than other methods. ‘Bycatch’ is another word for ‘collateral damage’, animals accidentally killed while hunting a specific species at sea. Much of the bycatch in dolphin-safe tuna is in itself seriously endangered, far more so than dolphins themselves. No, dolphin-safe tuna is not a good thing for the marine environment.

More and more people are becoming aware of and involved in environmental issues. They are paying attention to the environmental cost of the goods they purchase, insisting on packaging that can be recycled, lower power consumption from electrical goods, or higher mileage from their cars, for example. But what can you change in your daily activities to help the oceans, especially if you live far from the sea? The Marine Conservation Society have some advice, and there’s also a page of hints at The Ocean Project. One obvious thing is to be more informed and cautious in your seafood purchases, both sites have suggestions there. If you prefer to avoid seafood altogether, simply buying organic food is a good idea. That encourages farmers to produce more of it, which means less pesticide in use. Reduced pesticide use means less of it getting into our rivers and from there into the sea, finally ending up in marine mammals like that dolphin we were trying to save a moment ago.

You can find out more about World Ocean Day at the World Ocean Network site. Maybe one of the events that they list is taking place somewhere near you. If not, there are plenty of web-based resources available, like the 24 hours in the Ocean online event from the Musée Nausicaä. I’ll certainly be following that for some of the day.

Celebrating Wildlife

Last Friday, May 15th, was ‘Endangered Species Day‘ in America. This event is aimed at encouraging people to learn about endangered species and what they can do to help them. Endangered Species Day is coordinated by StopExtinction.org, and is held on the third Friday of May every year. It was first celebrated in 2006, so this year sees the fourth edition. The event was created by the US Congress, this year a resolution was introduced by Senator Dianne Feinstein encouraging schools to spend time teaching students about endangered species and conservation efforts, among other things. Senator Feinstein has been mentioned on this blog before in the context of another endangered creature, namely, Patricia Rattray.

StopExtinction.org had all sorts of events on their list for this year, educational, inspirational, hands-on, the lot. If you went to any of them I’d love to hear about it. Here’s a quick sampling.

The Wyoming Children’s Museum and Nature Center held presentations on how even one degree of warming can affect wildlife (and what you can do about it). Few climatologists today would say we can avoid one degree of warming, so this is setting the bar low. Even one degree can cause a great deal of harm to ecosystems, and it’s already happening. If you’re in any doubt about that, read these articles about Cedar Canyon Road and Aransas National Wildlife Refuge from The Clade.

For a more leisurely approach, there were events like the birdwalk on the Tijuana river in California, where you could see and learn about the birds that live there. This is actually a weekly event, so if you missed it last weekend you can go another time. Check the Tijuana Estuary Visitor Center calendar for details of all their upcoming events.

Then there’s at least one activity that can only be described as boring. That is to say, it takes place in the town of Boring, Oregon. No, I’m not making this up, the town of Boring really exists. Boring recently began a project to restore some parkland, and if you were there on Friday you could have participated in helping to restore the Boring Trail Station Trailhead Park (a note to the stopextinction siteadmins, you have broken links on that page). You can find out all you want to know about this project at their own webside, BoringStation.com.

The StopExtinction.org website has practical advice on things you can do to protect wildlife near you. They list some very simple things, like driving slower to reduce the chance of impact with animals. You’ll probably save yourself money that way too, I did. Another simple thing you can do is to plant native plant species in your garden. Many insects are poorly adapted to non-native plants, so planting native species can encourage them, and the birds and other animals that feed on them.

Coincidentally, across the Atlantic, ‘Fete de la Nature‘ took place in France at practically the same time. This is an all-weekend event, and again there are a variety of events. It’s a year younger than Endangered Species Day, having started in 2007, but boasts an impressive 300,000 participants in the past. Among the events taking place near me there was a chance to see chamois at the Col de la Faucille.

Of course, by now, those events have been and gone. Not to worry, there’s still plenty of opportunity to learn about the nature near you, endangered or otherwise. Many of the events organised for either Endangered Species Day or Fete de la Nature were organised by clubs or societies, who have an ongoing program of events. If you look them up, you might find something interesting. If they were one-off events, maybe you can contact the organisers anyway, and ask them if they plan to repeat it? If they get a demand, they might just do that.

If that doesn’t lead to something, why not just go out there and take a look for yourself? There’s plenty to see, and if you’re handy with a camera you can always find something worth photographing. Some of the best blogs out there are by nature-lovers, take a look at “Chipper’s Alley” in Oregon, “Everything is Permuted” in England, “2nd star to the right, straight on till morning…” in Malaysia, or “My birdpics” in Sweden for some of my personal favourites. Have fun!
