WW: Turtle boom



(Turtles have always been rare on the North Coast. Unlike the other three reptiles that manage to survive here [this one and this one and this one], they're egg layers, and the rotting wet and lack of spring sunshine makes that problematic. So it was that I, an inveterate turtle lover, had only ever found a single one in the lake I grew up on. On summer days I used row quite a distance to see him, hauled out on his log of choice.

In the intervening years the lake got severely over-developed and the swampy shore where our lone turtle lived turned into lawn. The very log he used to bask on was ripped out of the lake. Since that time, about when I was in college, I've only seen one other turtle here, in a nearby lake just a few years ago.

Then, while walking the dog near some containment ponds last week, I encountered six (!) of them, lined up on a log beneath the first real sun we've had this year. Sadly, they were too far away for a recognisable photograph, but as I rounded the corner, I found a small one, about the size of an adult's hand, close enough for my phone to steal a shot. Still too far for positive species identification, but the Western painted turtle
[Chrysemys picta bellii] being functionally our only native, this is probably that.

This must be how it feels to bag a photo of Sasquatch.

Next day, a friend posted photos of a similar line of turtles in my childhood lake, about 6 miles away. Both events have blown my mind.

It's hard not to draw the conclusion that this is yet another symptom of climate disruption. Less rainfall and elevated temperatures have almost certainly raised the turtle fertility here. I'm delighted to see them, but it's one more indication that our unique North Coast environment is rapidly disappearing.)

WW: Dunn's salamander


(Plethodon dunni; a melanistic specimen, lacking the wide, yellow-green back stripe and mottling typical of the breed. Another lungless North Coast salamander with no aquatic stage. Instead it lays its eggs under rotten wood, and they hatch into tiny, fully terrestrial young identical to the adults.)

Hermit Habit

Douglas Squirrel - 43494659481

The wildlife of the North Pacific rainforest is famously reserved; where the East has its flashy cardinals, red efts, and indigo buntings, our own rubber boas, rough-skinned newts, and varied thrushes are modestly beautiful. The odd Steller's jay or goldfinch may be a pleasant change of pace, but we're satisfied to return to the brown and russet uniform of our understated nation when they've passed.

While sitting my 100 Days on the Mountain, I sometimes daydreamed about founding a North Coast-native order of forest monks. And should that fancy ever gel, we will sit in the forest of my forebears, wearing the habit of our Douglas squirrel hosts: a hooded robe of honest Cascade umber, over an ochre jersey.

Ask a Dinosaur

Dinosaur tracks (Dakota Sandstone, Lower Cretaceous; Dinosaur Ridge, Colorado, USA) 37
Insight from a sangha-mate on Mastodon (appropriately enough):
One of the most important ideas to sit with – amid the convulsion of climate change – is that Earth was not made for us.

That idea flies against many religions, but also appears in secular settings, with even activists thinking of Earth as a sort of organic machine, a spaceship, a system that’s carefully balanced in absolute ways.

Those metaphors have power, but they’re ultimately unhelpful. Our place here is precarious because we don’t 'belong' in any cosmic sense.

We’re just here.

Local Boa Constrictor

So I'm breezing along a bike trail through rural country, feeling the exhilaration you get on a bike in Indian summer, when suddenly I find myself swerving hard to avoid a snake.

A large snake. Two feet plus, chocolate brown, mingled with the shadows.

Garter snakes routinely bask on that path, and what with the perfect climate and habitat, some grow quite large.

But not that large. Or that colour. And never in shade; Thamnophis is a sun-worshiper, intently keeping pace with her chosen beam as it crosses the pavement.

I hit the brakes and doubled back. And that's how I met my first wild rubber boa constrictor (Charina bottae).

Scion of an otherwise tropical family, the rubber boa lives farther from the Equator than any other. (As for the "rubber" bit, a glance at the photo here will cover that.) Thus Charina follows the pattern of North Coast reptiles: we have fewer species than other regions, but those exceptions are notably charismatic. A tradition this wayward constrictor further upholds by bearing its young live, like most other local reptiles, and then by being so uncommon, and so hyper-local, that though I grew up just 5 miles from that spot, I'd never encountered one before. The only specimen I'd ever seen, more than 40 years ago, was a captive juvenile taken in this self-same south-county microhabitat.

The heads of both were so small and sleek that telling one end from the other was initially difficult. This is part of an unorthodox defence strategy, as rubber boas hide their business end when frightened, and if the threat persists, lunge at the tormentor with their blunt head-like tail, to confuse it.

Those striking gold eyes, tiny for a boa, are the result not just of nocturnal habits but also the fact that rubber boas spend most of their lives – more than 50 years – beneath rotten logs and forest litter, where large corneas would be a medical liability.

But it's their disposition that's truly legendary. Charina is the Greek root of the English "charming", and likely the French câlin (cuddly, snuggly), both of which epitomise this disarmingly affable creature. When I knelt to pick it up – prudently, behind the jaws – he not only declined any attempt to bite, but even to escape. Instead he just rolled into a ball in the palm of my hand and buried his head beneath the coils.

The gentle shyness, along with the velvet softness of his liquid body, had me talking baby talk immediately.

"Funny snake," I chided, stroking his silky back. "You can't s'eep here; you'll get runned over."

As I struggled to bag a one-handed photo of his face, he eased into lazy loops and tentatively explored my gloved hand. I snapped away best I could (whatever advantages this newfangled phone photography offers, ergonomics ain't one), and shortly he relaxed, wrapping himself around my hand and wrist with real warmth.

Comparison to a long, linear cat would not be unwarranted.

I was sorely tempted to keep him, but didn't, of course. That their diet is made up almost entirely of new-born mice, and they won't even eat that half the year, was just another reason.

So I walked wistfully a ways into the trees and carefully deposited the sweet little guy on the forest floor. He edged away reluctantly, as if he'd've happily come along if asked.

How the pet industry missed this one is beyond me, but I'm glad these magical beings endure in my native forest.

WW: Hibernating snake


(Found this garter snake [Thamnophis sirtalis] asleep under a tarp that had been pulled over a stack of gardening supplies sometime last year. He didn't even flinch when I lifted the tarp, put it back, or lifted it again later to get the photo. So the dude's out for the duration.

I'll look for him out and about after things warm up.)

WW: Pacific treefrog


(This is Pseudacris regilla again. He's appeared here in the past, but this one is about the size of my thumbnail, part of a crowd of like-sized peers teeming in the high grass around the pond. Apparently the product of this year's hatch.)

Chance Encounter

Western Painted Turtle

The late hour kept me running a brisk 50 mph (the maximum controllable speed on gravel), so that an apparent chunk of slate in the road nearly slipped beneath my radiator before it caught my attention. Grinding to a halt, I stared at the plate-sized rock in the rearview mirror. Sure enough, it sprouted two yellow-striped forearms and a matching head, with acid eyes that glared at me through the pall of dust I'd raised. I snatched my camera and jumped out, thinking to bag a quick photo, then chase my chelonian friend off the road before a less attentive traveller squashed him flat.

But on my advance he sprinted into the undergrowth, with scornful disregard for my species' reluctance to apply that verb to his. I was left to herd him with stomping boots, back into the fading sunlight, to get my portrait. He appreciated none of this - not the running over, not the dirt bath, not the brisk jog, and most particularly not the herding. When the slides came back from the lab, I found a study of one seriously bent Western painted turtle.

Still, I had to admire the guy's pluck. We were a hundred yards from water. Wherever he'd come from, wherever he was going, he'd earned his rest in that place.

WW: Alien visitor


(This gold dust day gecko [Phelsuma laticauda] was spotted on a deck on Orcas Island, just over the Canada-US border. He's far from home [Madagascar], but I doubt he got here under his own steam.

Gold dust day geckos are popular pets, and also famous climbers, able to scale even plate glass. Though they've become a problem in the South Pacific, Orcas is likely in little danger, given its climate. Still, this little guy would be better off if someone could wrangle him and provide more appropriate living conditions.)

WW: Seafaring lizard


(My nephew and I went fishing all day a few weekends ago. We loaded the boat in his truck, drove across the county, launched in a large lake, motored about two miles to an anchorage, and fished for several hours. Then we repeated the process in reverse. When my nephew pulled the boat out of his truck that evening, he found this stowaway – a Northern alligator lizard – that must have been there the whole time.

Note typical belligerent pout.)

WW: Tadpoles again


(It's happened again: tadpoles growing on the beach. This time it's a brackish puddle by the headlands. I don't know if frogs breeding in this dangerous, inhospitable zone is new, or I just never noticed it before.)

WW: Castaways

(I found this Tupperware tub washed up on the sand, literally miles from any fresh water. Spring squalls filled it with rainwater, and some desperate tree frog had come by and laid eggs in it. By the time I happened by, thirty tadpoles were living off algae generated on the sides and detritus. They must've been there, egg and larva, for weeks, somehow avoiding being knocked over or slopped into by lethal salt surf. But they wouldn't survived much longer, as periods of full sun become longer and more numerous. I brought the tub home and released its inhabitants in a promising pond.)
