Big blue darner mating dragonflies

Big blue darner — what a treat! © SB 

Near Regina, Saskatchewan: The blue and gold flash of this big blue darner dragonfly was a late summer treat — especially when it stayed still long enough for a photograph, and when I caught a mating pair with my lens a few days later.

The pair below are in what's called the wheel — a position they can maintain while perched or in flight. (And yes, this pair were on another tree before they kindly flew to this one, which had better light.)

I don't pretend to fully understand what's happening here, except that the male is the one on top, clinging to the branch, and the female is the one below, clinging to him. The oddest part is that he is clutching her behind her head, perhaps to keep her from escaping before the deed to be done.

For more on dragonfly mating, I like the series of shots (and explanations) by Alistair Fraser, a Kootenay Lake nature blogger and great photographer in his Sex in the Park post.

And for more about dragonflies in Saskatchewan, Nature Saskatchewan has a great new book, Dragonflies & Damselflies in the Hand, by Gord Hutchings and David Halstead (who takes amazing dragonfly photos).


What are these? Big blue darner dragonflies. (I'd thought from the large, pale, thorasic stripes that these may be Sedge Darners... but David Halstead e-mailed to say that although it's difficult to tell, these are most likely to be Lance-Tipped Darners. He says these are fairly common on the prairies.)

Frost and migration

Regina, Saskatchewan:  Frost and migration — two signs of true fall. Finally, the weather is changing. After a long stretch of hot weather, daytime highs are dropping to the low teens, with lows edging to zero and below.

Yesterday, there was frost in the garden, tipping the edges of the oregano, thyme and parsley sugar-crystal white.

Birds are migrating, too. Canada geese wheel over our house — on the way to fields to feed, I hope. Is it really time for them to start south?

Fall: A restless time of year.

Stubble Burning: City Smoke Haze

Fire dragons, minutes from my house  © SB

By late Sunday afternoon, smoke from stubble fires in fields around Regina had filled the high sky with a fine gray haze, as if dragons had encircled us with their flames.

Apparently this is good land management, not air pollution (or attacks by alien — aka dragon — species).

Seems odd, but what do I know? I was brought up on asphalt, not wheat fields.

Maybe this looks unhealthy only to those of us with allergies. If seasonal burning works for the rest of you, I'll buy more antihistamines so I'm better prepared. (And read up on taming fire dragons.)

Thirteen-Lined Ground Squirrel: Stripes and Spots

When this Thirteen-Lined Ground Squirrel ran out in front of me, we both froze. I don't know what it thought I was, but in that first flash, I thought it was a snake.

Dramatic as the markings appear in a still shot — and also when the ground squirrel stopped to stare at me — they provided very effective camouflage when it was running through deeper grass.

This little rodent looked about eight or nine inches long, from tip of nose to tip of tail, and about two inches high. It wouldn't let me near enough to guess closer than that.

What is this? A Thirteen-Lined Ground Squirrel.

Lakeside Shells at Buffalo Pound

I lived beside the ocean for so long as a child that when I see a shell, I automatically think, 'seashell.' But there are land snails, too, and molluscs that live in lakes.

On Saturday, we drove out from Regina to Buffalo Pound Provincial Park to enjoy the late summer weather (33+C). These pictures were taken at the edge of Buffalo Pound Lake, where these (not sea!) shells lay in a line of debris washed along the shore by waves from speedboats and the wind.

What are these? Prairie lake shells, washed ashore?  (or land shells?

Autumn Colours in Hot September

Is it summer or fall in Saskatchewan? It was 33C today, near the end of September. We drove out to Buffalo Pound Provincial Park to look for birds at Nicole Flat, but the marsh walkways are destroyed (by spring floods? or neglect? or winter preparation?) and so we walked on the hill for while, in the heat.

Western Plains Garter Snake

Oh, what a lovely snake! Truly, this Western Plains Garter Snake is gorgeous, though completely unnerving if it twitches in front of your foot, where you thought there was only grass...

I came across this snake in the cemetery at Lebret, Saskatchewan, a day after being startled by a similar one near Fort Qu'Appelle, SK.

This is a Thamnophis radix, a common Saskatchewan garter snake. As the University of Alberta says, the quick way to ID this species is this: If you look down into the grass and see a dark snake with a red or orange stripe, it's likely to be the WPGS, aka, Thamnophis radix haydeni. 

This garter snake seemed totally unafraid of me. A good thing, as that meant it was prepared to pose!

Black-Crowned Night Heron near Craven SK

Along Highway 99, East of Craven, Saskatchewan: One of the biggest and most surprising birds I've seen is this Black-Crowned Night Heron. It was lurking in the newly renovated (thanks to this springs' floods) marsh along Highway 99, east of Craven. 

And yes, this is supposed to be a primarily nocturnal bird — but clearly one that doesn't follow all the rules, as it was only 1 p.m. or 2 p.m. — close to our bright prairie noon. 

This bird is huge — more penguin-sized than anything else. It's also very good at hiding — although perhaps not quite as good as it hopes it is... 

I'd stopped along the gravel shoulder to look at a Great Blue Heron that was hanging out further into the marsh, and it wasn't until after that heron flew away that I noticed this one lurking behind a clump of reeds. 

Flower note: They're too blurry to identify, but from the bright pink colour, the flowers in the top photo with the Night Heron may be Water Smartweed.

What is this? Black-Crowned Night Heron, a very large bird. 
Location: Along Highway 99, East of Craven, yes, Saskatchewan.

Full House at Thistle Diner

Full house at Thistle Diner: Butterfly, fly & bumblebee  

I'd like to describe this picture — the last in a series with these three insects — in terms of a children's cross-genre fantasy epic...

Princess Butterfly recoiled in horror as the steel-plated robot bumblebee crawled closer, his henchman fly guarding the blossom behind him. 

And she does. Recoil, I mean. Her proboscis, that is. Which is coiled, indeed. (And, while I regret any potential gender stereotyping, in this story, the butterfly is, in fact, a princess in a flowing yellow gown.)

The shot immediately before this picture, in which the butterfly appears to first notice the bumblebee, is on my Prairie Wildflowers blog.

Potter, Burrowing Owl: Rotating Head

What's front or back when your head rotates like this? 

There is something eerie about a creature like Potter, the Burrowing Owl, whose head can rotate 270 degrees, so that he stares at you like this, body aiming forward, face back.

For Potter's full bouquet, see below, Burrowing Owl Floral Arrangement. (Try doing it with your head facing backwards...)

What is this? A somewhat-tame burrowing owl — he's being imprinted to help educate people about the issues his at-risk species faces.
