Pink salamanders. I'm not kidding.

 Photo: Brian Parsons

Just when you think you've seen it all, along comes an email from Brian Parsons, reporting pink salamanders. Not only that, he's got the photos to back up this outrageous claim.

Brian is Director of Planning and Special Projects at the Holden Arboretum in northeast Ohio. He is a botanist, but is keenly interested in everything in the natural world, and for years has been monitoring a strange population of spotted salamanders, Ambystoma maculatum, on the Holden grounds.

QUICK PLUG: If you haven't visited Holden Arboretum and its 3,600 acres, add it to your bucket list. Not only does Holden contain a wealth of interesting ornamental plantings, its grounds also conserve some of the best natural areas in the northeastern corner of Ohio. Many rare plants occur naturally, and its varied habitats support a spectacular diversity of birds, including many unusual breeding species. The place is a state and national treasure.

This is my photo, of a pair of normally pigmented spotted salamanders, just like the one that graces the brand new Ohio Wildlife Legacy Stamp. Cool as they may be, Brian's pinkamanders make these boys look mundane.

This shot shows one of the pink salamanders in a pool along with a normally pigmented individual. The contrast is jarring. Brian reports that this population of pink individuals has long been present at Holden, and their numbers are on the increase. Last night was the main push of spotted salamanders into the Holden breeding pools, including these bizarre pinksters.

Apparently these amphibians are erythrochroic; they possess the same genetic anomaly that causes the pinkness in the pink grasshopper of my last post, and Pinky the katydid. I don't know how common erythrism is in the amphibian world, but I've never seen it until Brian shared these amazing photos.

A bit of research reveals a smattering of documentation about erythristic salamanders, most notably the so-called "red morph" of the widespread red-backed salamander, Plethodon cinereus, such as THIS PAPER.

If anyone can shed any insight on these animals, or knows of other "pink" salamander populations, please share. And thanks to Brian for sharing the story of these decidedly odd amphibians.

Thanks for plugging Holden and its diverse biodiversity. I hope to see the pink females move to the vernal pool Thursday night if the forecast holds. Some of the males left the pool last night, but there were still several pink males in the pool. If any of your readers in NE OH want to see them for themselves they should feel free to contact me.

Where is Holden? I might be in NE Ohio this summer.

@Sharkbytes: just click on the words "Holden Arboretum" in my post - it's a link that will take you to their site and all you need to know.

That's a very gracious offer, Brian, and I would take you up in a heartbeat were I not already committed to something. Next year, though, I want to come up and witness this strange beasts firsthand! Hopefully some others can make it over tomorrow night.

The Pinching Beetle, a rather brutish looking bug

The world is awash in beetles, and they come in all shapes and sizes. Few of them can match the intimidation factor of a Pinching Beetle, Lucanus capreolus, though. Those formidable looking mandibles look like they could slice off a finger.

Today was one of those coolly diverse days. I started off down in Fayette County, visiting the farm of a friend. He has restored about 25 acres of wetlands, and the response by the animal community has been nothing short of phenomenal. Blizzards of dragonflies of many species, amphibians galore, and nesting Blue-winged Teal, Pied-billed Grebe, and Sora. Among MANY other things. And all in a short two years. Add water and they will come.

Then, working my way home, I ducked into a Madison County cemetery that has a thriving population of Thirteen-lined Ground Squirrels, and shot images of our native prairie dog. Then, I stopped at a spot along Little Darby Creek, waded on in, and procured some pretty nice shots of various stream bluets and dancers. …

Calliope Hummingbird in central Ohio!

A hatch-year male Calliope Hummingbird strikes a pose. Small but tough, the hummingbird was feeding actively yesterday in 39 F temperatures. It frequents feeders and gardens at a home in Delaware County, Ohio, about a half-hour north of Columbus.

Fortunately, the wayward hummer appeared at the home of Tania and Corey Perry. Tania is a birder, and knew right away that the hummingbird was something special. For a while, the identification was up in the air, which isn't surprising. The Calliope Hummingbird used to be placed in its own genus, Stellula, but has recently been submerged into the genus Selasphorus, which includes Allen's, Broad-tailed, and Rufous hummingbirds. The latter two, especially, are quite similar to the Calliope in subadult plumage. Rufous is the default "vagrant" hummingbird here, with dozens of records and birds turning up annually. There is but one Ohio record of Allen's Hummingbird, from late fall/early winter 2009. Ditto the Calliope Hummi…

Snowy owl photography tactics - and things NOT to do

A gorgeous juvenile female snowy owl briefly catches your narrator with its piercing gaze. It's doing its Linda Blair/Exorcist trick - twisting its head 180 degrees to look straight behind. Owls have 14 neck vertebrae - double our number - which allows them such flexibility.

These visitors from the high arctic have irrupted big time into Ohio and adjacent regions, with new birds coming to light nearly every day. Probably 80 or so have thus far been reported in the state, and some of them have stuck around favored spots and become local celebrities.

I went to visit one of these birds this morning - the animal above, which was found last Friday by Doug Overacker and Julie Karlson at C.J. Brown Reservoir near Springfield. In the four days since its discovery, many people have visited as is nearly always the case when one of these white wonders appears near a large population center or is otherwise very accessible.

And as is always the case, people want to photograph the owls. And th…
