Winding down, IRFD 2015

This year's International Rock Flipping Day was quiet. While there was a good response before the actual day, few people reported in with findings, and Googling only turned up one other entry. Maybe people had the same problem finding good rocks as I had.

But we did find a few real gems!

First, did you know that we humans aren't the only ones flipping rocks? Anna, of The BlennyWatcher Blog, let goatfish do all the work for her, and just sat back and took video footage. Go see.

On the IRFD Facebook page, the first post showed a slug and a pupal case. (I think that's a moth inside.)

And Slow: Children at Nature Play went out with two kids and found a Dunn's salamander, and other critters. "So much fun!", she says.

The salamander. From the IRFD Facebook page.

In the comments on the Celebrate Science IRFD post, Dana Rau posted a Rock Flipping Day poem.

I lift your heavy door 
to find
busy you
on your way from
one side of your space
to the other. 
The surprising sunlight
curls you into
a spiral
to protect all those legs
and underparts. 
Between fight and flight
you choose
freeze
and hope
someone remembers
to shut the door
so you can get on
with your interrupted
business.

And that's about it. I found the beetle, and the ants and spider. And later on, down at the shore, I turned over a stone and crabs scuttled quickly out of sight. Except for one brave little guy; he was ready to take me on, defending his territory.

"Back off!"

"And I don't care how big you are, either!"



I think, unless there is a public outcry, this will be the last year I host the IRFD. If anyone is interested in taking it up, I'll be glad to participate, of course.

Grumble and wonder; IRFD 2015



Urbanization is hard on rolling stones. Or flippable rocks. I set out full of optimism to turn over a few familiar rocks in my neighbourhood. But they're gone, or locked away: the builders and developers and pavers have moved in. The vacant lot across the street, which last year was a square block of rocks and weeds, and a killdeer nest, and another block of incipient forest full of twitterings and rustlings, has been bulldozed and fenced. The alleyway behind the church, once the passageway to gently mouldering farm buildings, now leads to more fences and developers' signs. Our street has been widened and sidewalked; the ditch where I used to watch for skunks is no more. Even Cougar Creek Park has been "cleaned up" and hemmed in with housing estates. Our road in has been re-routed and lined with "No Parking" signs.

On the far side of a schoolyard, past the newly-grassed lawns and playing fields, past the neatly-trimmed treed area, back against the fence where nobody goes, I finally found a half-dozen forgotten rocks. And a few small beasties still sheltered there.

The beetle was under the third rock I turned. A small spider raced over my hand as I flipped the fourth, and disappeared under the grass. And then I hit paydirt under a small rock, almost too small to be worth flipping, I thought.

Very small, very pale, orange and tan ants. This is on the underside of the stone itself. The ant at the top right seems to be toting a shred of a pupal cocoon.

Here, they're wrestling a cocooned pupa into a crack in the stone.

A cluster of cocoons on the ground underneath the stone. No ants are with this bunch, but there's a pretty green springtail at the top.

I wonder about ants. When they're stressed, they race around frantically, pulling and dragging their babies, (eggs, larvae, and/or pupas) trying to get them under cover. But it's almost as if they were moving randomly; an ant will drag a cocoon one way, forget about it, and go off in the opposite direction, talk to another ant, and race away to pull at different cocoon, going the wrong way half the time. And yet somehow, the cocoons manage to get hidden away; A Random Walk with a twist in it somewhere.

I replaced the stone before the ants finished dragging away their cocoons, so they wouldn't have all the work of hauling them back out again.

The next rock, a bigger one, hid one racing beetle, and one big spider who sat there, trying to be invisible.

I don't think I've seen this pattern before.

I got too close, and she was gone in a flash; I didn't even see her run.

A handful of beetle

I've been out flipping rocks, and came home with a stack of photos to process. Here's the first of the lot.

All out of breath.

Could that beetle ever run! I chased him and chased him and chased him through piled dead leaves and old sticks, caught him and lost him and caught him again. Then when I finally had him, he must have figured he was safe in my hand, and just sat there while I aimed the camera at him, one-handed.

The rest of the photos and story will be along presently.

Tomorrow is the day we flip rocks.

Just a quick reminder: sometime today or tomorrow, a bunch of us will be out there turning over rocks to see what lives underneath. I hope you will join us!

It's late, and I've been birthday-partying until my eyes can hardly stay open, so I'll just re-paste the instructions, in case you missed them.


Instructions: 

If you're joining in for the first time, here's a quick rundown of the procedure.
  • On or about September 13th, find your rock or rocks and flip it/them over. 
  • Record what you find. "Any and all forms of documentation are welcome: still photos, video, sketches, prose, or poetry." 
  • Replace the rock as you found it; it's someone's home. 
  • Post on your blog, or load your photos to the Flickr group. (Even if you don't have a blog, you can join.) 
  • I will collect the links, e-mail participants the list, and post it for any and all to copy to your own blogs. (If you're on Twitter, Tweet it, too; the hashtag is #rockflip.) 
  • There is a handy badge available for your blog, here. (Or copy it from this post.) 


More details, history and suggestions are in this post.

And now, goodnight! I'll be looking for your reports, blog posts, photos, etc, come Sunday morning.

Calling all Rock Flippers!

Just a reminder: International Rock Flipping Day is next Sunday, September 13th. It's time to make your plans, invite your friends, and look for an interesting rock (or rocks.) Small rocks, big rocks, flat rocks, chunky rocks, even man-made rocks; they're all good, and no telling what lives underneath. What will we find this year?



In case you missed it, history and instructions are here.

Rocks, lichen, moss, old leaves. Burnt Bridge, Bella Coola valley. I should have had a flashlight to see what lives in that mini-cave.

If you're joining in for the first time, here's a quick rundown of the procedure.
  • On or about September 13th, find your rock or rocks and flip it/them over. 
  • Record what you find. "Any and all forms of documentation are welcome: still photos, video, sketches, prose, or poetry." 
  • Replace the rock as you found it; it's someone's home. 
  • Post on your blog, or load your photos to the Flickr group. (Even if you don't have a blog, you can join.) 
  • I will collect the links, e-mail participants the list, and post it for any and all to copy to your own blogs. (If you're on Twitter, Tweet it, too; the hashtag is #rockflip.) 
  • There is a handy badge available for your blog, here. (Or copy it from this post.)


Have fun, and be careful out there!

Rock Flipping Day coming up!

It's that time of year again; here in the north, the summer heat is dissipating, the rains are coming (YMMV). Back-to-school sale flyers are showing up in our mailboxes. And the rocks are beckoning!

It's time for the annual International Rock Flipping Day (IRFD), this year as usual, on the second Sunday of September, the 13th.


I love rock flipping day, in part because people find classes and even subphyla of critters that they've never encountered before. (Sara Rall, commenting after last year's RFD.)

No-one has volunteered to host it this year, so we're back here for another year.

I'm getting lazy: I'll post, again, the instructions and history as before.

History:

Rock Flipping Day was started by Dave Bonta and Bev Wigney in 2007. The idea is simple; in Dave's words,
... we pick a day for everybody to go outside — go as far as you have to — and flip over a rock (or two, or three). We could bring our cameras and take photos, film, sketch, paint, or write descriptions of whatever we find. It could be fun for the whole family!

37 bloggers joined in that first September.

On 9/2/2007, people flipped rocks on four continents on sites ranging from mountaintops to urban centers to the floors of shallow seas. Rock-flippers found frogs, snakes, and invertebrates of every description, as well as fossils and other cool stuff.

Instructions:

If you're joining in for the first time, here's a quick rundown of the procedure.

  • On or about September 13th, find your rock or rocks and flip it/them over. 
  • Record what you find. "Any and all forms of documentation are welcome: still photos, video, sketches, prose, or poetry." 
  • Replace the rock as you found it; it's someone's home. 
  • Post on your blog, or load your photos to the Flickr group. (Even if you don't have a blog, you can join.) 
  • Send me a link. Or you can add a comment to any IRFD post. 
  • I will collect the links, e-mail participants the list, and post it for any and all to copy to your own blogs. (If you're on Twitter, Tweet it, too; the hashtag is #rockflip.) 
  • There is a handy badge available for your blog, here. (Or copy it from this post.) 

Important Safety Precautions:

A caution from Dave:

One thing I forgot to do in the initial post is to caution people about flipping rocks in poisonous snake or scorpion habitat. In that case, I’d suggest wearing gloves and/or using a pry bar — or simply finding somewhere else to do your flipping. Please do not disturb any known rattlesnake shelters if you don’t plan on replacing the rocks exactly as you found them. Timber rattlesnakes, like many other adult herps, are very site-loyal, and can die if their homes are destroyed. Also, don’t play with spiders. If you disturb an adjacent hornet nest (hey, it’s possible), run like hell. But be sure to have someone standing by to get it all on film!

About Respect and Consideration:

The animals we find under rocks are at home; they rest there, sleep there, raise their families there. Then we come along and take off the roof, so please remember to replace it carefully. Try not to squish the residents; move them aside if they're big enough; they'll run back as soon as their rock is back in place.

Previous Rock Flipping Days:

  • 2007 (In the halls of the mountain millipede) 
  • 2008 (IRFD #2) 
  • 2009 (The early bird gets the worm.) 
  • 2010 (Mongoose Poop?) 
  • 2011 (We Haz Critters) 
  • 2012 (Great Expectations) 
  • 2013 (And in 2013, I totally forgot until it was too late. Never again!) 
  • 2014 (At the Edge of the Ordinary) 

Last year, a total of 18 Rock Flippers posted their findings; a collection of four-, six-, eight-, and multi-legged critters. What will we find this year? Put it on your calendar, go flip some rocks, and we'll see!

(This has a Rock-flipping kid.)

A couple of others also posted their photos on Twitter, but they had also added them to the Flickr pool, so they're on the first list, which I'll repost here:

Over in the International Rock Flipping Day Flickr group, many more interesting things have been discovered:

Of two-tailed bugs, absent salamanders, and flipped rocks

Well, we've gone out and flipped our rocks (or not - one of us cheated took an alternate approach.)


It has been a quiet year, probably because I forgot last year, and we lost momentum. In spite of that, we made some interesting finds.

VERY IMPORTANT UPDATE: I just checked Twitter; there are a bunch more Rock Flippers over there. I'll add them to the list in a new post.

Here is the lineup, as it is now, copied from Heather's blog, At the Edge of the Ordinary:


Over in the International Rock Flipping Day Flickr group, many more interesting things have been discovered:

And this was a handy tip: Heather had found a pillbug under one of her rocks. "Or maybe a sowbug," she said; she finds them confusing. So do I, unless I pick them up; pillbugs roll themselves into a ball; sowbugs don't. (Here's a sample pillbug.)

But Sara Rall, in the comments on Heather's post, gave us a quick way to tell the difference, even from a photo.

To tell a pill bug (which can roll up) from a sowbug (which can’t), look at the back end. If it has two “tails” that stick out you have a sowbug (which would be my guess in the photo, but I can’t really see well enough to be certain).

Here's a family of sowbugs I found under a paving stone next door:

"Two-tailed" woodlice, aka sowbugs.

Zooming in. See the tails?

BugGuide has a photo of pillbugs side-by-side with a sowbug for comparison.

Thanks, Sara!

As usual, there were a couple or more Rock Flippers who did the "work" but didn't pass on their findings. If you're one of them, either Heather or I would be happy to add your name to the list; just give us a shout.

And many thanks to Heather for hosting this year. And I hope it rains soon and she finds a salamander; she well deserves it!

Dem dry stones



Cougar Creek drains from the clay soils near our house, seeps under a couple of malls, meanders over to Cougar Creek Park with its lagoons and beaver dams, and plunges into a steep canyon. At the bottom end, it tunnels under the road into Sunshine Hills, and out into the Burns Bog flats.

We started our rock flipping excursion from that road, heading upstream, at first, into the canyon.

Reflections of the trees at the top of the Canyon. This year, the creek is shallow and slow.

Dying alder leaves and shadows of horsetails on the stones along the river bank.

We turned over many stones, both on the banks, and in the dry areas of the creek bed. Under a few, we found pillbugs, and one earthworm. Nothing more; the ground was dry, the creek bed scoured clean, and barely damp.

Where the creek was slightly deeper, held back by sticks and leaves caught on a few rocks, I turned over a rock, saw something flashing in the current, and caught it. I spread it out on the next rock to examine it.

A gruesome find. A red dragonfly, minus most of the head and abdomen, probably eaten by fish. The wings are intact. Nothing there to interest a hungry trout.

We crossed the road into Burns Bog. This part of the bog was once extensively mined for peat, and is criss-crossed by walls and railway tracks. A large part of it was paved over, but the pavement is cracked and mossy, buckling as the ground has heaved under it. Alders and maples grow in the gaps.

Moss breaking pavement, making soil for larger plants.

Cracked pavement. I looked in the cracks; nothing was moving.

It's been a dry summer; even in the shade, the moss was dry and scratchy. The ground underneath was no damper. We turned over many rocks and chunks of broken concrete, finding mostly dry soil, baked hard.

Under one slab of concrete, a few reddish ants had dug tunnels. They have something damp and bluish in the upper centre here; some sort of dead critter.

The underside of a paving stone. Ant trails, hot and crispy. No ants in sight.

Pillbugs

And a small, sleeping slug. I have never seen one before with a spotted white face; I didn't know there were such critters.

And this I will never understand: Burns Bog is supposed to be an ecological preserve, even this once-mined area. Access is mostly on foot, and the trails are long. Why, then, do people haul garbage deep into the woods here? On foot, carrying heavy trash, when we have door-to-door pickup or easily available bins?

Every time, we find something. Bottles and buckets, bicycle parts, grocery store trolleys, old cabinet TVs, rotting mattresses, shoes . . . This time, it was electronics. Underneath the chunks of concrete.

TV? Or what?

And what is this? It's plastic, backed with cardboard.

This I do understand. There's a graffiti'd wall just beyond.

It's tomorrow!

International Rock Flipping Day, that is.

Here's a handy badge for your blog. (Copy, save, and paste.)

We're looking forward to a good turnout this year; I hope you'll be joining us.

A quick reminder: if you've flipped rocks before, you know the drill. If not, here's what we'll be doing, from our host this year, Heather at "At the Edge of the Ordinary".

  • Find a rock. Sometime around September 14, flip it over and record what you discover. You can flip more than one rock.
  • You can record your findings in whatever way you prefer, whether that is through photos, videos, sketches, prose, or poetry.
  • Share your findings in a blog post (and use the badge at the beginning of this post, if you like), or upload your photos to this Flickr group.
  • ... I will collect all of your IRFD links and post them here for everyone to explore. You can then share them on your blog or social media (the hashtag on Twitter is #rockflip).

I (that's me, Susannah) will be monitoring the Flickr group, and will pass on the links to Heather.

Sunday is the Day itself, but it's ok to jump the gun if Sunday is impossible for you. I, for one, will be home expecting company all day Sunday, so we're heading to Cougar Canyon this afternoon to find some good rocks.

A likely-looking rock, at Boundary Bay.

And remember: be safe*, be respectful**, and have fun!

*One thing I (Dave Bonta) forgot to do in the initial post is to caution people about flipping rocks in poisonous snake or scorpion habitat. In that case, I’d suggest wearing gloves and/or using a pry bar — or simply finding somewhere else to do your flipping.

It's next week!



Just a reminder: Rock Flipping Day is coming up next weekend, September 14th*. Have you picked out your rock yet?

Small rock in my tank. Lots of life on top; I wonder what's underneath?

I'm still chasing baby snails, and trying to be there when some of the eggs hatch. Wish me luck!

Rock Flipping Day update

It's confirmed; this year, our host for the International Rock Flipping Day (#rockflip) will be Heather Mingo, on her blog, At the Edge of the Ordinary.

Heather is another of my favourite BC bloggers. She describes herself as,
... a writer, blogger, and amateur naturalist living in a small town in the Canadian province of British Columbia (one of the most beautiful places in the world) with 3 cats, 700+ books, and 40+ house plants. ... a geek about plants, fungi, insects, ecosystems, and all that, and I even have a degree in natural resource science to prove it.
... and her blog:
The edge of the ordinary is a place where you can remember your interdependence with the rest of nature, rediscover your inherent creativity, and simply be.  The edge of the ordinary is not in the wilderness or far from home.  It is here, all around you: in the sky, in the air, in the vacant lots, in the cracks in the sidewalk, in the small details that most people ignore.  At the edge of the ordinary you will discover a world of depth and meaning and everyday wonder.  A world peopled by plants and animals and fungi and slime moulds and mountains and rivers and stars and atoms and galaxies.  A world in which to be human is to be both very small and also very large.


A perfect fit for all us Rock Flippers!

So the weekend of September 13/14, then, go out and flip your rocks, record your findings, and send your links to Heather by email or by filling out her contact form. I will be monitoring the Flickr group and passing those links on to her, as well. Any other links that arrive here, I will simply forward.
