Lenten roses available at Spring Plant Sale this Saturday

Probably planted originally by Alice Ijams, who lived at the location from 1910 to 1964, the plant is known as Lenten rose because it blooms in winter between Christmas and Lent. On a gray winter’s day, it would have been a cheery sight to Alice.
Not native to North America, the shade-loving perennial with deeply lobed leaves is an invited guest from the Old Country. Although the flower resembles a wild rose, it’s actually a hellebore. The genus in the buttercup family is native to much of Europe from western Great Britain east into Romania and Ukraine.

Native rose available at Spring Plant Sale

Carolina rose, a.k.a. pasture rose (Rosa carolina) is now in bloom along the fence in front of the Raptor Enclosure near the parking lot at Ijams.
A true native rose, it grows in almost all the states and Canadian provinces east of the Great Plains. And can be found in a wide variety of open habitats, from thickets and open woods to roadsides and along railroads.

Second hummingbird favorite in bloom at Ijams

Now that red buckeye’s flowering season is beginning to fade, another hummingbird favorite is starting to appear: crossvine (Bignonia capreolata), a native semi-evergreen, woody vine. It’s a climber generally found growing up a supportive tree.
Like most plants that use hummingbirds as pollinators, crossvine has tubular flowers that range from red to orange to tangerine in color. Also known as quartervine, the plant gets its name from its cross-shaped pith. If you cut a stem, you’ll discover it has four chambers that form an “x” pattern.
Crossvine flowers are also noted for their curious fragrance, most often described as “mocha-like" which I imagine might serve to attract cappuccino-loving insects with extra long tongues. (Hummingbirds are lured by color not scent.)

Tree swallows have taken up residence at Ijams

Jennifer and Emily report that Tree swallows, (Tachycineta bicolor), are nesting in the artificial gourds near the TVA-KUB solar panels on the Universal Trail.
Tree swallows are migratory, spending their winters in Mexico, Central America and the Caribbean, but historically they nested in the western part of this country. Tree swallow nesting in the Tennessee Valley, and even our state, is a fairly recent occurrence.
According to Chuck Nicholson, author of the Atlas of Breeding Bird of Tennessee, published by UT Press, the first recorded tree swallow nest in Tennessee was discovered in 1918 at Reelfoot Lake. It wasn’t until 1968 that other nests were documented, this time in Anderson and Maury Counties. After that, nests have been reported every year and since the late 1980s, the nesting population has increased dramatically. Today, they’re fairly common throughout the state.
Tree swallows nest in empty cavities, hollow trees, bluebird boxes or even empty round gourds. Unlike their cousins, the colony-loving purple martins, the dark metallic blue backed tree swallows prefer to build their nests isolated from other swallows.

Roosting red bat found by Ijams visitor

Recently Sue Wagoner from Illinois visited Ijams hoping to find a barred owl to photograph. She did but Sue also found something else of interest napping in the trees.
Something much smaller.
Sue emails, "Here is the Eastern red bat (Lasiurus borealis) we saw on the trail at eye level. I saw the reddish fluff sticking out of the leaves and wondered if it was some artifact caught on the tree, or a weird gall or a fuzzy seed pod or something, so imagine my surprise when I lifted the leaf and saw movement, a face and some toes (or fingers). What a cutie...he looks like a little imp."
Eastern red bats roost individually, often hanging upside down in trees.

Fothergilla in bloom near the Visitor Center

Fothergillas are shrubs native to the American Southeast that are grown as ornamental plants for their puffy-white flowers in spring and bright color of their fall foliage. There are several in bloom near the Visitor Center at Ijams.
John Fothergill (1712-1780) was an English physician, plant collector and philanthropist.
As a physician in London, Fothergill had an extensive practice noted for successfully treating patients during the epidemics of influenza in 1775 and 1776. His hobby was botany. At Upton near Stratford, Dr. Fothergill had an extensive botanical garden (today known as West Ham Park) with many rare plants collected from various parts of the world. He also helped finance the travels of American naturalist William Bartram, who collected plants from the Southeast to be shipped back to England.
Fothergillas, the shrubs collected in America, were named for the English physician. We all should be so honored.

Kindergarten group watches osprey pair overhead

Walking along North Cove Trail you never know what you are going to hear or see, and yesterday was no exception.
Ospreys build their nests near water on platforms put up by people, in the tops of trees or on any high flat surface. I’m not sure where this pair is nesting, but there is a platform on the end of the Dickinson Island where the Knoxville Downtown Island Airport is located across the channel from Ijams.
A convenient nest to see is on the railroad bridge next to the now closed for repair Henley Street Bridge. It is easily seen from Neyland Drive and the female is incubating now.
Because Ijams is so close to the river, you may hear and see ospreys on any of our trails. We consistently see them even flying over the Visitor Center.

Spring's return stirs wintering mourning cloaks

The reason? They get a head start being one of the few species that overwinters, i.e. hibernates as adults.Mourning cloaks are widespread: tundra south to central Mexico and in Eurasia, primarily Scandinavia. In Sweden they are known as sorgmantel literally "mourning cloak" presumably a name that comes from their cloak of dark purple-brown color.
Host plants for the caterpillars: Female mourning cloaks lay their eggs on willows, aspens, elms, cottonwoods and paper birches, but seem to prefer assorted willows.
On Tuesday, March 29, I saw a mourning cloak flutter trough the plaza in front of the Visitor Center for the first time this season.

Waterthrush serenades from Homesite stream

I quickly grabbed my binoculars and ran down the trail. I knew exactly where to find him. Waterthrushes forage, sing and build their nests along streams in forested areas. True to form, this beautiful bird was singing right off of the Discovery Trail by the stream. We got several great looks at him as he held his bill to the sky and belted out his song as loud as he could.

Spring comes early for one lone lethargic toad

A few weeks ago, I was digging through a pile of soil filling up pots for plants with a volunteer and another Ijams’ employee. All of a sudden the volunteer yelled, “Oh no! A dead frog!”

Bluebells blooming in the sodden wet places

Virginia bluebells is the more commonly used folk name for Mertensia virginica the pale blue flower now in bloom at the nature center.
“Hello. I’m Virginia cowslop. How are you?”
Nevertheless, this delightful blue wildflower is often found in wet, damp lowlands near water. Look for it near the Visitor Center and downstream from the Ijams Family pond along the Discovery Trail.

Harbinger of spring
On a lovely walk along Discovery Trail yesterday afternoon, naturalist Emily Boves and I discovered a delicate little butterfly, flitting amongst spring wildflowers. The butterfly is a Falcate Orangetip (Anthocharis midea).
The Falcate Orangetip is one of the true harbingers of spring, flying through vernal woodlands only a few feet above the ground. This particular butterfly allowed us to get within a few feet of it, which gave us the opportunity to study its beautiful markings.
The top of the wings are white, with black spots near the front edge of the forewings, which have a very characteristic hooked tip. Only the males (shown in the photo) have bright yellow-orange coloration at the tip. On the underside of the wing both sexes have heavily marbled markings, usually of gray-green or yellow.
Be sure to stop by the trail surrounding the Ijams Homesite for a true taste of the color and sounds that represent spring in East Tennessee!

Raucous peepers peeping from every damp location

The spring peepers (Pseudacris crucifer) have been calling for several days, but late this afternoon with all the rain, they seemed to be peeping from every damp location at Ijams.
The Plaza Pond was filled with the raucous voices of the ardent male calling to attract a mate.
The question is: How can such a little thing—roughly one inch long—make so much noise?

Annual Woodcock Walk finds energetic timberdoodle

Call it a rite of spring, or, in this case, a rite of late winter.
Last night my fellow bog-sloggers and I experienced a purely perfect natural moment. An American woodcock (Scolopax minor) a.k.a. timberdoodle performed his courtship display, his ardent "peenting" song, right on schedule at Forks of the River Wildlife Management Area.
Our annual Ijams "Woodcock Walk" has been a popular event for over 15 years. This year, Jenifer Roder and Emily Boves helped me host the somewhat muddy activity.
At the appropriate hour—twilight, just after sunset—our group was hidden in the cedars surrounding the traditional singing ground to watch it all happen. He seemed oblivious of his voyeurs. He was crooning for a female, a momentary partner to share his lust for life. If he knew we were there, he simply did not care. For he was living in the moment as were we all.
It was a good time.

Chorus frogs croon, spring on the way

“Cree-ee-ee—eeek."
"Cree-ee-ee—eeek."
"Cree-ee-ee—eeek."
Spring is on the way. How do I know? The Western Chorus frogs (Pseudacris triseriata) herald its arrival! And with this tiny species of tree frog, the more the merrier.
Many of the ponds at the nature center, including the small ones at the Homesite are filled with their froggy choruses. The small gray males collect in great numbers to crooooooon, hoping to attract mates. And, as we all know, hope springs eternal, even in the tiniest of hearts.
