Guided Moss Hike at Wild Haven Nature Area
Lorie Hetrick-Volenberg, author of the newly released “Mosses of Missouri Through a Hand Lens”, will be leading a bryophyte hike at Wild Haven Nature Area on Sunday October 5th at 1:00 p.m. If you haven’t purchased her book, you will have the opportunity to do so from 1:00–1:30 p.m., with the hike starting at 1:30 p.m. We will build upon the beautifully designed self-guided moss walk by Louise Flenner. Both Lorie and Louise will be there to share their knowledge and enthusiasm about these petite but incredibly beautiful and interesting plants.
At a leisurely pace, the walk will traverse 1/2 mile of gentle topography, including two stream crossings that are commonly dry, especially in the fall.
Bring a hand lens if you have one. And there’s no harm in having binoculars as well!
Google map to Wild Haven. Park in the small parking area near the pavilion or along O’Rear Road.
A rain date of Sunday, October 19th at 1:00pm is scheduled in case of bad weather. If the weather is in question, please check the hike listing on Lorie’s website for the most up-to-date info regarding postponement: https://mossesofmissouri.com/bryophyte-hikes/
RSVP through Lorie’s website is optional.

Wednesday, October 8, 2025 | 5:00 p.m. to 6:30 p.m. (social), followed by swift watching, ending by ~7:10 p.m.
Logboat: Social; Later: Swifts!
Feel free to take part in one or both components of the evening’s activities:
Part 1: Social at Logboat Brewing Company (~5:00 to 6:30 p.m.)
Hang out with birders and discuss birds (plus nature in general, geology, and more)! Perhaps there will be gossip about goldfinches. Or chat about chats.
Swallow some beer if you desire, but non-drinkers are equally welcome at this family friendly venue. Beer, hard cider, and non-alcoholic options are available from Logboat. Food trucks are sometimes an option, and bringing your own food/water is always allowed.
Wren you’re there, time may fly swiftly, and you’ll have no egrets.
We’ll hope to grab a table outdoors on the upper deck, but if you don’t see us there, take a gander. For those new to the group, clues to identify us include binoculars and bird-themed table decorations.
Part 2: Swift Chaser (arrive by 6:00 p.m. for directions; finishing by ~7:10)
Chimney Swifts gather at dusk to roost overnight within chimneys. During fall migration, it is not uncommon to see hundreds of swifts gather at, circle around, and enter a single chimney. However, the dynamics of where swifts roost on any given night can be complex. We currently know of 10 buildings that have hosted roosts within the past year in/near downtown Columbia. We can offer guesses about what locations are likely to be the most active and exciting to watch, but we’d love help in getting eyes on a number of buildings so we know what’s going on at multiple locations.
If you’d like to do some swift watching, please arrive at Logboat no later than 6:00 p.m. for full details and directions. Sunset is 6:40 p.m. on October 8, 2025. The period of peak activity is generally between sunset and half an hour after sunset, but we’ll probably want to head for our chimneys a bit earlier than that.

October Membership Meeting: “Monarchs, Milkweed, and the Milky Way” by Dr. Vayujeet Gokhale
For the October Membership meeting, join us for a lecture by Dr. Vayujeet Gokhale (Truman State University) who will discuss the importance of the Lights Out Program in his talk titled “Monarchs, Milkweed, and the Milky Way.” This talk will be co-sponsored by Daniel Boone Regional Library and DarkSky Missouri.
This presentation calls on all nature lovers to work together toward a comprehensive approach to conservation, following in the footsteps of Rachel Carson and Doug Tallamy. The ability to see the Milky Way at night from one’s front yard is just as much an indicator of a healthy, natural environment as is the presence of a pesticide free, natural habitat with natives that attracts, say, the iconic monarch butterflies. Just as pesticides and invasive species degrade precious and life-nourishing natural resources such as soil and water, the indiscriminate use of unshielded, bright blue-white LED light degrades another underappreciated natural resource: natural darkness at night. Most living beings need this darkness – humans and other animals need it to regulate much needed sleep, and to maintain and improve their mental and physical health.
Most birds migrate at night in the cover of darkness, whilst many lifeforms take advantage of the darkness to forage, hunt, and breed. Responsible outdoor lighting is not just good for the environment and human health, but it also enhances the safety of pedestrians and drivers by reducing direct glare and clutter. In this presentation, we will discuss the relatively straightforward steps you can take to protect natural nighttime conditions in a manner that is not only safe, aesthetically pleasing, ecologically responsible, but also addresses the legitimate outdoor lighting needs in our communities.
Vayujeet Gokhale is a professor of physics and astronomy at Truman State University. He earned his BSc. in physics (’96) and MSc. in nuclear physics (’98) from the University of Bombay, followed by a PhD in astronomy from Louisiana State University (2007). He lives just outside of Kirksville, Missouri with his wife Michelle, two young kids, a dog and a cat. Dr. Gokhale maintains his sanity by watching Seinfeld, Quentin Tarantino movies, and listening to dad rock. He loves the night sky, and is training to be a Missouri Master Gardener and Master Naturalist. Dr. Gokhale adores America’s National Parks and dreams of someday becoming an astronomy park ranger at the Arches National Park in Utah.
Please note the location of this month’s meeting at the Daniel Boone Regional Library (Columbia) and slightly earlier time, 6:00 PM, to accommodate library hours.

November Membership Meeting: Greg Renner on the history and artistry of decoy making
Please join us for our November Membership meeting, presented by Greg Renner.
Renner, an expert in and collector of early-20th century duck decoys, will be presenting a talk titled, “History and Artistry of Decoy Making, with particular attention to decoy making done in the State of Missouri.” Greg will discuss the history and basic art of decoy making, as well as the storied practice of decoy manufacturing in the state of Missouri. He will bring examples from his collection of wooden, hand-painted decoys made in Jefferson City between 1921-1945, when there were three different decoy manufacturers in the city. Greg’s talk promises to appeal not only to collectors and hunters, but also anyone who might have an interest in the various species of waterfowl that were imitated by early decoy making.

Black(bird) Friday: Evening at a Boone County Roost
Whether or not you spend part of Black Friday in a shopping frenzy, there’s an evening opportunity to celebrate the day as Blackbird Friday by visiting a Boone County roost that has hosted millions of blackbirds on a nightly basis at this time of year in recent years.
The evening arrival of huge flocks of blackbirds creates a spectacle that can wow non-birders as well as the most well-traveled birders. But just how a given night will play out is always a bit of a surprise, as factors that affect roosting concentrations and locations aren’t well understood. The best way to find out is to visit. Everyone is welcome to attend, including visiting family members. Leaders Eric and Joanna Reuter will be on-site to describe the background history of the roost, then we’ll watch as the show unfolds; each time is unique.
One disclaimer: Human cases of histoplasmosis (a fungal infection) have been associated with other blackbird roosts with a multi-year presence. We have no way to assess the actual risk here. Use your own judgment about whether this is a good trip for you.
Where: Meet at the site (click here for map; note that Google shows the name of the road as “Dun Bar” even though it is actually “Dunbar”). The viewing area is at the end of a dead-end gravel road with plenty of parking along the side of the road. No bathrooms are available.
When: Sunset on November 28 is ~4:48 p.m. We’ll gather at 4:00 p.m and expect to stay through ~5:45 p.m. Dress warm, as the temperature tends to drop precipitously with the setting sun. In the event of weather that creates hazardous road conditions, any necessary postponement updates will be on the listing on the CAS website.
Additional background on the roost:

Self-guided moss walk: Wild Haven Nature Area
Have you taken the time to examine mosses close up? And to think about the relationships between mosses and birds? We’re excited to announce a new, self-guided moss walk at Wild Haven Nature Area that encourages you to do just that!
The trail guide is formatted to be easily read on a mobile device (with the goal of saving paper; please don’t print it).
Download the guide here.
The total length of the hike is under a mile, but it’s easy for time to fly when examining mosses, so plan for at least a couple of hours at Wild Haven. Conditions in winter and early spring are ideal for looking at mosses; sunlight bathes the forest floor, ticks aren’t especially active, and neotropical migrants aren’t yet distracting. But the trail can be completed at any time of year.
We suggest that you bring:
—A hand lens or magnifying glass. This will help you appreciate the miniature world of mosses.
—A spray bottle with water (but no chemical residues). Use to rehydrate mosses when conditions are dry; watch the leaves swell with water in front of your eyes.
—A water bottle for yourself, plus snacks, standard hiking gear, and binoculars for the birds.
No potable water is available at Wild Haven, but there is an outhouse (hand-crafted by CAS volunteers).
Louise Flenner developed this trail to share her knowledge and enthusiasm about mosses and their importance to birds. Thanks, Louise!
