"The best place to study nature is in the field. The woods are great classrooms, and nature's great book is ever open before us. We may read from its pages, and no matter how much we learn, we find that we can still read more."

— John Burroughs

Directive 1: Put away your smartphones.

Early Sunday morning it was gray and overcast, a prelude to rain for most of the day. There were many new arrivals and I added a couple dozen species over the weekend to my non-existent 2024 list. I sure am glad I gave up eBirding, jibing some birders I walked past who were staring at their smartphones entering data. "You're doing it wrong — look up into the trees!" I said. They weren't really all that humored, briefly glancing up from their connectivity but then immediately going back to work.

Directive 2: Please stop doing this everywhere you bird ...

You know what you're doing? You're spreading Garlic Mustard, that's what. This invasive plant is so resilient it will still go to seeds despite being pulled out by its roots. If you're going to pull it, bag it, and remove it from the conservancy. Rainwater will wash the seeds off the paved trail, rapidly infecting more habitat. To be sure, there's so much Garlic Mustard at the Pheasant Branch Creek Corridor it's really a lost cause. Still, whenever I see the pulled plant littered along the trail, I think of a generic pseudo-naturalist/birder wearing a Tilley hat and think "Look at me, I'm helping!" But you're not.

Anyway, here comes May!

Just Bins!

"Like all magnificent things, it's very simple."

― Natalie Babbitt

Birding solo with just a trusty pair of binoculars offers a serene and intimate connection with Nature that's hard to replicate in group outings. The tranquility of the moment, the ability to move at your own pace, and the heightened awareness of your surroundings create a deeply rewarding experience. It's a time for mindfulness, for embracing the sounds and sights around you, and for reveling in the freedom to explore wherever your curiosity leads.

And no eBirding!

Most species below were observed at the Pheasant Branch Creek Corridor this morning, but others at the west confluence pond. Bumped into the venerable Chuck Henrikson, who was looking for an S. palmarum he had heard (from another birder) was in a particular area ― I found it by its chip-note. Perhaps challenging given all the S. coronata clamor, but relatively easy for me.

Capturing Spring: Wildflowers and Tiger Beetles!

"Study nature, love nature, stay close to nature. It will never fail you."

— Frank Lloyd Wright

Sheesh! I'm really getting behind on photography and blogging ...

We got nearly a foot of snow in southern Wisconsin about a week prior to the solar eclipse. Down in southern Illinois, things looked to be at least a week or two ahead in terms of flora and fauna, but we're quickly catching up. While things are greening up after some much needed rain, this past weekend the landscape was still mostly monochromatic earth tones. However, in small ways spring's vibrant colors were detectable in the form of birds, bugs, and blooms.

On Sunday, the Pheasant Branch Creek Corridor was teeming with Setophaga coronata, or "Butter-butts" as some affectionately refer to them. While the Myrtle subspecies probably won't be renamed, the Audubon variant will need to be dealt with so as not to offend. Incidentally, the ancient Greek word myrtos, from which the name "Myrtle" is derived, refers specifically to the Myrtle Plant Myrtus communis — S. coronata eats their berries (and other fruits), but they're primarily insectivorous this time of year. It was also nice to see and hear my first of spirng S. pinus and S. palmarum.

Given recent summer-like temperatures, I thought it wise to make my annual early spring trek to The Nature Conservancy's Spring Green Preserve in Sauk County for Splendid Tiger Beetles. It was very dry prior to the rain we've been getting since the outing. Naturally, I checked the rocky outcroppings for any potential buzztail dangers prior to searching for insects.

But it didn't take long to find one, the little sentinel monsters of the rocks ...

Moving in for the coveted macro close-up ...

There were Common Claybank present as well ...

What a second ... what's up with this?

From 'A Field Guide to the Tiger Beetles of the United States and Canada':

"Recent DNA studies of the Splendid Tiger Beetle, Common Claybank Tiger Beetle, and Green Claybank Tiger Beetle indicate that these arguments could be moot, as their genes are so similar they may all be one species." (David L. Pearson;C. Barry Knisley;Charles J. Kazilek.)

I observed three different copulating pairs, in each case a more bronze-colored male was either mating with or mate guarding a green-colored female.

Copulation! See the male's aedeagus (sex organ)? Ever since I first found Splendids and Claybanks together on the bluff's outcroppings at Spring Green Preserve, I thought about the possibility of interbreeding — there are notable variants; some look more Splendid than Claybank, and vice versa.

The deed is done, but now he's mate guarding ...

Male tiger beetles engage in mate guarding to ensure their paternity and reproductive success. By guarding a female after mating, a male can prevent other males from mating with her, thereby increasing the likelihood that his sperm will fertilize her eggs.

Did you know that tiger beetles can toss small rocks to injure their prey?

Just kidding. I think this beetle mistook it for something living. After a quick sampling with its mandibles, it almost immediately set it down and resumed hunting. On occasion I have observed on gusty days tiger beetles will notice small debris blowing on the surface and chase them down for mandibular inspection.

And some additional portraits ...

Nestled within the picturesque Baraboo Hills, Baxter's Hollow is a haven for ephemeral wildflower enthusiasts, offering a glimpse into the vibrant tapestry of Nature. On a recent excursion, I was captivated by the delicate beauty of Bloodroot, Round-lobed Hepatica, Yellow Trout Lily, and American Beauty. These native gems adorned the forest floor along Otter Creek, painting a scene of natural elegance.

Though not intrinsically difficult subjects, photographing wildflowers offers a unique opportunity to blend scientific observation with a deep appreciation for the beauty of Nature. In capturing the intricate details of wildflowers, photographers not only contribute to seasonal botanical documentation, but also immerse themselves in the present moment, cultivating a type of connection. Each photograph becomes a snapshot of biodiversity, highlighting the delicate balance of ecosystems and the resilience of plant life. It's especially rewarding after a long Wisconsin winter, marveling at the wonders of the natural world, fostering a deeper appreciation for the beauty that surrounds us this time of year.

And Mayapple from another location ...

And what weekend outing would be complete without a visit to the Sauk City Canoe Launch for tiger beetles?

There were hundreds of Bronzed Tiger Beetles.

But still only a few Big Sand ...

These are different angles of the same individual.

Smile, big guy!

So, that's 5 tiger beetle species already! As spring unfolds, each bird, wildflower, and tiger beetle captures a moment in Nature's ever-changing tapestry. Through photography, we preserve these fleeting glimpses and deepen our connection to the beauty and resilience of the natural world. Let's cherish these moments and continue to explore the wonders of the spring season.
