Last scheduled program of 2011: Happy Holidays!



It was cold, two days before Christmas with just enough time to squeeze in one final WalkAbout before the holiday break.


Special thanks to all who came out for the bird walk along Will Skelton Greenway to the west.

Looking forward to other adventures in 2011!

28th Annual Holiday Craft Party is Saturday

Logdeer welcome visitors to the nature center

Once upon a time—and indeed, many of us still remember it—most holiday decorations were made by the family.

Kids would sit around the kitchen table with mom crafting ornaments, wreaths and cards, family keepsakes that would last for years. It was also an excellent way to keep little hands busy (and little minds occupied) waiting for the day when the Big Guy "tarnished with ashes and soot" would somehow make his way down the chimney with a bound. How did he do that?

Unwrapping those heirlooms every December brought back a flood of memories of holidays past, that is if the mice hadn't eaten the strings of popcorn and cranberries.

Those days are alive and well at Ijams.

This Saturday, December 17, 11 a.m. to 2 p.m. is our 28th Annual Holiday Craft Party.

Celebrate the holiday season with this recycled craft open house. Learn how to reuse common household items to make fun and festive gifts and decorations like candles, cards and ornaments. Creative keepsakes that will become family heirlooms. Cost: $2 for Ijams members, $5 for non-members. Please call (865) 577-4717, ext. 110 to register.

Surprisingly hard-to-find, logdeer seen at nature center

Ever-alert and hard-to-find woodland logdeers


Ijams does not often have deer. Although they are routinely seen at Forks of the River WMA due east of the nature center, the fleet and nimble hoofed-ones are rarely here, that is until this week when three woodland logdeer were spotted outside the Visitor Center.

Winter Bird WalkAbouters brave the cold day



Sometimes, the thrill IS in the hunt. You may not find a lot but it's the camaraderie of the group that saves the day.

So it was for our Saturday Winter Bird WalkAbout. Our goal was to find birds that only spend their winters in the Tennessee Valley; their summers are spent elsewhere.

It was chilly, almost cold. On a walk east of the Visitor Center on the Will Skelton Greenway the only winter bird we managed to find was a single yellow-rumped warbler.

But even so, it was a good day.

The next Winter Bird WalkAbout will be Friday, December 23 at 2 PM. To sign up call 577-4717, ext. 110.

Pair of ivory-bills find 'forever home' at Ijams

"Two stuffed and mounted ivory-billed woodpeckers (one a male and one a female) finally found a forever home as a part of Ijams Nature Center's lost species exhibit.

The amazing story of how they came to be donated involves a beautiful old picture frame, a lifelong friendship between two men who grew up together in Worcester County, Mass., two friends in a Knoxville book club, and a letter written by Ijams Director Paul James."


For the rest of the story, go the Birdlife column by Marcia Davis at ivory-bills' journey.

Birthday parties are fun, especially if you are a butterfly



Flutter by. Flutter by. Even in early December you can find butterflies at Ijams. Especially if you plan a butterfly-themed Birthday Party with Kara.


This afternoon butterflies of all colors (and one yellow-and-black bumble bee boy) were seen flitting about all over the Visitor Center and Plaza. It was a delight to all who happened to be anywhere nearby. Summer is eternal in the hearts of the young.


Happy Birthday, Gryphon!

Winter Birds WalkAbout creeps into creeper

Surprisingly, the Ten Mile Creek Greenway through the heart of west Knoxville can be a good place to find birds. 


The Winter Birds WalkAbout today found several of interest including a sharp-shinned and red-shouldered hawk plus a few species only here in the winter: yellow-rumped warblers, dark-eyed juncos, yellow-bellied sapsuckers, white-throated sparrows and a lone brown creeper. But, creepers tend to always be alone at this time of the year. Creeping along, blending in, minding their own business.


Ijams WalkAbouts are scheduled on most Saturdays at parks and greenways around the county. For the next one, visit the Ijams online events calendar.

Ijams owl prowlers flush great horned



AS the sun slipped below the horizon to the west and cold air moved in from the river to the north, the Ijams owl prowlers set out to find those feathered, nocturnal wonders: hoot owls.


You can find five species of owl—Eastern screech, barred, great horned, barn and even migrating saw-whet—at Seven Islands Wildlife Refuge in east Knox County, although the Northern saw-whet only passes through. (Locally, it nests in the higher elevations of the Smokies.) 


Our group heard two or three screech-owls along the road, but the real treat was flushing a great horned owl.  


Initially, it seemed to respond with a loud squawk from a distance when we played a tape of an eerie barn owl (If I were a vole, the mere scream of a barn owl would cause me to drop dead in my tracks!) but a recording of a great horned owl itself brought it closer to investigate our group huddled in the cold near a wooded ridge. But it continued to squawk not hoot at us. 

Eventually, the largest owl in our valley flew over us for a eyeball-to-eyeball look-see and perhaps noting we were no real threat, just a bunch of shivering, bundled humans with dreams of warm cocoa, it disappeared into the darkness never to be heard again.

Later I learned that young great horned owls do a lot of squawking and very little hooting.

Thanks to AmeriCorps members Katie and Zack for helping and to Nora, Justine and their Seven Islands friends for joining us.

WalkAbouters find winged buckeyes at Seven Islands

                                                                                                                                                                               
WalkAbouter Ruth holding a buckeye butterfly


You never know what you might find on a WalkAbout.

Last Saturday, we were looking for insects and spiders at Seven Islands Wildlife Refuge in east Knox County. And even though it was November, it was sunny and warm, so we were lucky.

Perhaps the biggest surprise was how many buckeye butterflies that were out and about. 

The common buckeye (How could anything as beautiful as a buckeye be labeled common?) feeds on nectar but also takes fluids from mud and damp sand. Males perch on bare ground or low plants, occasionally patrolling in search of females, but they are not territorial. Buckeyes have bold patterns of eyespots and white bars on their upper wing surface. Such a special thing! The populations of late fall, overwinter as adults, waiting until next spring to reproduce. 

Ijams thanks Rikki Hall for leading the WalkAbout.


Common Buckeye (Junonia coenia)
And Happy Birthday Ruthie! Nine-years-old is a very good thing to be.

The nature center goes to the dogs, but in a good way






A warm and fuzzy, wet-nosed thank you goes to all who attended our first Dog Days Event last Saturday. The turnout was great and the friendly, tail-wagging dogs managed their human companions within park guidelines. 


Ijams is really excited about our new partnership with PooPrints, a green initiative helping improve local air and water quality to create a cleaner and greener community.


Watch for other Dog Days events in the future, and ask us about a special Ijams membership for your canine partner.

Ijams welcomes new snake to our education staff



Ijams has a new program animal: a young captive-bred corn snake.

We've had it about two months and because of the hands-on care of our vet, Dr. Louise Conrad, it has about tripled in length.  It's a healthy eater.

Once known as red rat snakes, the name "corn snake" is a holdover from Southern farmers who often found the colorful snakes in their corn cribs, eating the mice that ate the corn. A good thing. The farmers would rather have the snakes than the mice. 

The new snake has already been used in a couple of outreach programs.

Welcome to the staff.

Jack-O'-Lantern appears in time for all hallows' eve

Jack O'Lantern mushroom 

Just in time for the spooky holiday, educator Sabrina DeVault discovered a Jack O'Lantern mushroom (Omphalotus olearius by some, Omphalotus illudens by others) growing at the Homesite.

As the name suggests, this jack-o'-lantern is an orange- to yellow-gill mushroom that to an untrained eye appears similar to some chanterelles, and is most notable for its bioluminescent properties, perhaps a by-product of its metabolism. A fresh cut specimen is said to glow eerily in a dark room. Something I've yet to test. However, unlike the chanterelle, the Jack o'Lantern mushroom is indeed poisonous.

So witchy-poos and goblins and headless horsemen alike, you better watch out.



Boo! Trick or treat.

Ijams Quarry canoe trip: it's like déjà vu all over again

Canoeists on Ijams Quarry Lake


Anyone for jelly babies? Well, actually they are not babies but full-grown adults.

I expected we'd see herons and turtles on our canoe trip on Ijams Quarry Lake this morning, but I didn't believe we'd find the rare freshwater jellyfish that appear occasionally. Afterall, we found them on last month's canoe trip and even that seemed late in the season to me. The medusas' appearances called "blooms" are sporadic and unpredictable from year to year. It usually happens during the hot weather of the late summer months, or a least that's what I believed.

Yet, even on a cool morning in mid-October we found them. 


Freshwater jellyfish (Craspedacusta sowerbyi) are not native to North America. They first appeared in the lake at Ijams in 1997.  Since then, I've always thought they were rare, yet on two canoe trips in a row, we have found them.

The small bell-shaped jellies—about the diameter of a U.S. penny in their hydromedusa stage—are virtually transparent and as wispy as the Smoky Mountains' smoke. 

They look like bubbles, bobbing up and down, undulating underwater; one of the most ephemeral lifeforms I've ever seen or written about. Here one minute and gone the next, and surprise, surprise, they were here again this morning. 

What did Yogi say, "It's like déjà vu all over again."


The next guided canoe trip of the quarry lake is scheduled for Saturday, November 12 at 10:30 a.m. To register for it call 577-4717, ext. 119.

Special thanks to the Mind's Eye Society Knoxville Chapter for participating in our Haunted Lantern Tour of the Ijams Quarries: Mead's and Ross Marble two weeks ago.

The local group told the story of the Bell Witch—Tennessee's most famous haunting—at the Keyhole at Ross Marble just after darkness flowed into the abandoned quarry pit. (Not the best place to be after the sun sets.) I've been told if you mention the witch in an appropriate place, she will appear.

Did she?

I can't say for fear that mentioning her name again will make her manifest herself in my office.

Blackhaw viburnum, a mockingbird's dream buffet

Blackhaw viburnum, Viburnum prunifolium

The blackhaw viburnum growing at the west end of the Visitor Center is loaded with small fruits—called drupes—at this time of the year, which is why you often find mockingbirds nearby. They love their fruit. 


The deciduous shrub native to the Southeast can reach heights of 18 to 20 feet. Planted in a row, you'll have a natural wall in only a few years to hide your air conditioning unit or, in our case, compost bins.

Watch out for saddled caterpillars with bristles

Saddleback caterpillar, Sibine stimulea


Ijams educator Sabrina DeVault found this one on a Alexandria laurel just before Sunday's plant sale.

The saddleback caterpillar is the larva of a species of slug moth native to the east. The adult moth is rather brown and nondescript.


The caterpillars are primarily chartreuse with cocoa brown at both ends and a prominent, white-ringed brown dot in the center that resembles a saddle, hence the name, although they are also known as "packsaddles" for the same reason.



The caterpillars have a pair of fleshy, bristly "horns" at either end, and these, like much of the body are covered with urticating hairs that secrete an irritating venom. Stings can be very painful, so beware. 


Ouch! Nature can have a bite. But it's an excellent survival strategy. 


When I was kid, I was once stung. I still remember it and developed a fear of anything green with a saddle, including chartreuse horses.

Hummers passing through Ijams and local environs



This has been a good year for migrating hummingbirds. I've recieved several phone calls about large groups (called charms) spending time in backyards, around the feeders and late-blooming nectar flowers, especially jewelweed.


Tiffiny Hamlin and her husband Warren attended one of my winter bird classes. Afterwards, we found a hermit thrush for them to photograph.

This week Tiffiny sent these two hummingbird photos. Both young male ruby-throats just beginning to grow in their dark neck feathers.

Results of first Ijams' BioBlitzes presented

Coyote caught on camera at Ross Marble



On Tuesday, September 13, Ijams was pleased to welcome back former AmeriCorps team member, Laura Marsh. During her tenure at Ijams last year, Laura conducted two BioBlitzes on our newest property, the Ross Marble Natural Area. 

A BioBlitz is a is a special type of field study, where a group of scientists and volunteers conduct a 24-hour biological inventory, attempting to identify and record the species in a given area. 

In May and June, Laura worked round the clock with a fantastic team of local experts and volunteers to survey a wide variety of species from insects and plants to mammals and birds. Over 260 species were documented over the two 24-hour surveys. Some of the highlights included a camera survey and nocturrnal mist net demontration. The cameras captured photographic documentation of two coyotes, a red fox and a gray fox—a species that had not been documented at Ijams prior to the BioBlitz. 

Mist nets were used by TVA biologists Charles Hofer and Holly LeGrand. Three individual bats were captured, measured and released. We hope to use the data gained from the surveys to enhance our eduational programs and materials. 

A heart-felt “thank you” goes out to all the volunteers and biologists who generously donated so much time to make the BioBlitz efforts such a success!

Ijams canoeists find ephemeral treasures

Ijams September canoe group

The first Ijams guided canoe trip open to the public on Ijams Quarry Lake turned up an oddity, ghostly aquatic apparitions.

I expected we'd see herons and turtles, which we did, but I didn't believe we'd find the rare freshwater jellyfish that pop up occasionally. The medusa's appearance is sporadic and unpredictable from year to year.


Freshwater jellyfish (Craspedacusta sowerbyi) are not native to North America. They first appeared in a greenhouse aquarium in Washington D.C. in 1907. Since then, they've slowly spread across the country and are usually found in calm, freshwater reservoirs, impoundments, gravel pits and old quarries. Ninety years after they were collected in the nation's capital, the jellies first appeared—or were first documented—in Mead's Quarry Lake in 1997. (Retired TVA biologist Bob Terry, husband of Ijams educator Jean Terry, identified them from collected samples.)

Generally, the small jellies appear in their medusa stage during the heat of summer. This is why I didn't expect we'd find them in mid-September on a cool morning. Lynn Keffer, a canoeist in our group, was the first to see one undulating just below the water's surface, virtually transparent and as wispy as morning fog. About the size of a penny, the jellies are clear to slightly milky white. Walter Cromer, another paddler in our group, quickly became attuned at spotting them swimming around our canoes.

They look like water bubbles, bobbing up and down underwater; one of the most ephemeral lifeforms I've ever written about.
