Neo-tropical migratory “coffee birds” find home in both temperate and tropical agroforestry systems

tl;dr: check out theses links to see Maggie Musto’s coffee bird series. Coffee birds are neotropical migratory songbirds that live on multi-strata coffee agroforestry farms in Central America during the winter. In summer, coffee birds live in Appalachian Ohio, including within and beside the multi-strata chestnut/pawpaw agroforestry happening at Woodcock Nature Preserve. As you read about coffee birds, un-mute each post and listen to their vocalizations as a mnemonic to help you identify coffee birds when you hear them. For more help, you could go on a hike of the 5K Friendship Trail at Woodcock Nature Preserve. While you’re hiking, you can use the Merlin Bird ID app to assist in identifying coffee birds. And if you found this project valuable, there are many next steps you can take. For starters, please donating to Woodcock Nature Preserve and supporting their mission. You could have a conversation about coffee birds and Bird-Friendly Coffee with other coffee enthusiasts. You could even check out a winter coffee bird tour in Costa Rica with Birding Man. Southern Ohio Chestnut Company would be happy to offer technical assistance with agroforestry design and installation to support coffee birds on your property.

As land manager at Woodcock Nature Preserve, I sometimes get requests to facilitate student internships. There is a surprising amount of interesting happenings going on at Woodcock, and I suppose that it’s natural that a certain percentage of college students would desire to contribute their time and talents to the project. In summer 2025, I had the pleasure of working with student intern Maggie Musto. Maggie produced a body of work that deserves to be studied and celebrated, so we’re cataloging that work here.

Maggie is a senior in communication studies at Ohio University. She was recruited by board president Nate Beail-Farkas to help Woodcock. On her own, Maggie applied for a student grant to pay her for her time, and selected Woodcock Nature Preserve to work with. But what would she do? As it turned out, my friend Ryan Dibala at Birding Man Wildlife Tours and I had been developing an environmental education story. We pitched Maggie and the board. Maggie was already thinking of making a series of social media posts, which was a good fit. We got the green light.

My pitch was to focus Maggie’s posts on the birds of Woodcock Nature Preserve. Particularly, the “coffee birds”. Coffee birds are species of migratory songbirds that live in coffee plantations during the winter months, but that come back to live and reproduce in the Midwest, Great Lakes and Appalachian regions during the summer. Both the Audubon Society and the Smithsonian have historically prioritized supporting the coffee birds’ winter habitat. Typically this has been through supporting chocolate and coffee based agroforestry in Latin America. Instead of single strata monoculture fields of chocolate and coffee, these big environmental organizations promote multi-strata agroforestry, where the smaller, shade tolerant coffee and chocolate trees/bushes are cultivated under taller trees, so that the birds can still have a place to roost and feed in the higher canopy. Overstory species in these multi-strata cacao and coffee plantations usually have secondary uses as well. Nitrogen-fixers like Inga edulis (Ice cream bean), Erythrina poeppigiana (Coral tree), and Gliricidia sepium (Quickstick) are particularly valued for low-input systems, as they reduce fertilizer needs. Timber species like Cordia alliodora (laurel) and Cedrela odorata (Spanish cedar) provide long-term income. Many of these trees also have additional specialty human uses for woodworking, charcoal making, food for humans and fodder for livestock, green fencing, and medicinal applications of different parts of the plant. As a result of the Smithsonian and Audubon Society’s work on this, many environmentalists, especially birders, are now familiar with the concept of “bird friendly coffee”. An accessible example of this is Trader Joe’s Shade Grown Espresso. Ryan reports that “It’s fantastic and relatively inexpensive for shade grown java.”

many people don’t think about is that these coffee birds actually reproduce in temperate areas, not on the tropical coffee and cacao agroforestry farms. And when the birds are at their summer home at Woodcock Nature Preserve, they’re actually living and reproducing in another multi strata agroforestry system! Southern Ohio Chestnut Company leases part of the preserve. They have recently gotten coverage in a local paper for their Chinese chestnut orchard, which is an overstory above the shade-tolerant pawpaw fruit trees in the understory. Some of these coffee birds have been directly observed nesting in the trees of this temperate agroforestry site. Isn’t that interesting?! Because of the MODUS tower that Bob Scott Placier put in place at Woodcock, we can track individual birds that make the migration annually between the shade-grown coffee plantations and chestnut agroforestry systems. If people had sufficient interest, we could specifically track the movement of these coffee birds between these tropical and temperate agroforestry sites. The way this series ties together wildlife biology and agroforestry systems, from north and south of the equator, was the hook.

Ryan helped generate a long list of coffee birds that are found at Woodcock. Ultimately, Maggie only had time to write about 20 of the coffee bird species. We feel that the coffee birds that didn’t get a post still deserve an honorable mention. So (in no particular order) here are additional coffee bird Species you can learn about: Chestnut-sided Warbler, American redstart, Tennessee Warbler, Blackpole Warbler, Blackburnian Warbler, Black and White Warbler, Nashville Warbler, Magnolia Warbler, Bay-breasted Warbler, Black-throated Green Warbler, Palm Warbler, Eastern Wood Peewee, Yellow Vireo, Red-eyed Vireo, Philadelphia Vireo, Summer Tanager, Swainson’s Thrush and the Ruby-throated Hummingbird. These species are already known from WNP, according to citizen science observations E-Bird.

Maggie used pictures from Bob Scott Placier’s long standing bird posts on social media, data from the Motus Tower at Woodcock Nature Preserve, as well as information from eBird. She reached out to Sayre Flannagan, Ron Cass, Ryan Dibala and friends, Bob Scott Placier and Susan Calhoun for anecdotes about each coffee bird. Maggie’s weekly conversations with expert birders, including these supporters and board members of Woodcock Nature Preserve, gave structure to the internship.

As a volunteer-run, donation based organization, we hoped to educate the public in a way that sets the stage for increasing our donor base. Some of our regular visitors probably already know a bit about coffee birds. But I wonder how many coffee drinkers, roasters and cafe workers would actually be quite surprised that their Bird-Friendly Coffee also requires habitat management, right here where we live. If you already buy “Bird-Friendly coffee”, maybe you would consider making a tax-deductible contribution to support the programming, infrastructure development and maintenance, and habitat management at Woodcock Nature Preserve. The organization is a local 501(c)(3) that is already providing high quality habitat to the same coffee birds that are supported by purchasing Bird-Friendly Coffee. And maybe you’d like to go on a birding tour on a coffee agroforestry Costa Rica farm with Ryan Dibala. If you do, you might see some familiar feathered faces that you learned about from hiking at Woodcock, and following us on social media. 

2025.06.24 #1 research update on “Chinese chestnut seedling mycorrhization with porcini”

Introduction 

Supported by SARE, the Southern Ohio Chestnut Company has begun a farmer-led research project. “Chinese chestnut seedling mycorrhization with porcini”. This is our first update to the public.

Porcini mushrooms go by many names. This project works with porcini specifically –Boletus edulis– and also a group of other closely related “King Bolete” mushroom species from the Boletus genus. In practice, King Boletes are all harvested, traded and cooked rather interchangeably. They are all high-dollar culinary mushrooms. King Boletes are different from most other cultivated mushrooms in that they don’t normally break down logs or wood chips or bags of grain for their nutrients. Instead, they symbiotically trade resources with host trees- energy from the tree is traded for soil nutrients and water, between the ectomycorrhizae of the King Bolete and the fine roots of the tree. Because of this foraging strategy, would it surprise you to know that most King Bolete mushrooms are harvested from the soil surface? Yes, King Boletes are harvested in chestnut, conifer and oak woodlands, plantations and orchards. 

There has been successful inoculation of chestnuts and conifers in Europe and Asia. More research is needed into the basic biology of porcini as it relates to the inoculation of Chinese chestnut seedlings, however. To our knowledge, no chestnut grower in North America has derived significant income by selling the ectomycorrhizal mushrooms from their orchards. We hope to be the first! If this is exciting to you, follow these updates to learn along with us!

What have we learned and accomplished so far?

King Bolete identification and nomenclature

At Martha Bishop’s recommendation, Badger Johnson and Aly Gordon attended a spring 2025 foray with the Ohio Mushroom Society (OMS) in Lake County, OH. OMS is a chapter of the North American Mycological Association (NAMA), and puts out “The Mushroom Log” as a bimonthly newsletter. We suggest to everyone reading this, if you haven’t already,  join NAMA and your local chapter! It is of good value, for learning mushrooms on forays, in newsletters, and with many exclusive online classes and lectures. We search the Mushroom Log for King Boletes identification guidelines. Here is some of what we learned:

“Current research indicates that genus Boletus in N. America will eventually be whittled down to include only the “kings” –Boletus edulis, Boletus variipes, Boletus separans, & a few others.” -David Wasilewski

“This group (editors note: this group consists of the King Bolete group referred to above) is characterized by having a pure white pore surface in the young fruitings, which changes to yellow and finally greenish olive. The flesh is white and does not bruise. The stem is typically reticulate but mostly near the top… reticulation is white.” 

-Dick Grimm

This trend that Mr. Wasilewski described, of geneticists reclassifying every species from genus Boletus that doesn’t look like a King Bolete, has held constant ever since. In the eastern US, genus Boletus now includes only Boletus edulis, Boletus subcaerulescens, Boletus variipes, Boletus separans, Boletus variipes var. fagicola, Boletus atkinsonii and Boletus nobilis– all of which are culinarily considered King Boletes. This is a favorable situation for farmers, field biologists & foragers- all are choice edibles! Dr. Bryn Dentinger lays it out nicely in the chart below in his talk “ Boletus edulis update presented by Dr. Bryn Dentinger (UMNH) via Zoom on November 17 2022”. We made an infographic for the species native to the eastern US.

An accidental successful inoculation and annual harvest of King Bolete in Ohio

Martha introduced us to Walt Sturgeon. Walt is a mushroom field identifier and teacher of great renown in OMS. Walt is also the author of “Appalachian Mushrooms: A Field Guide”. He is a native of East Palestine, OH. More than 10 years ago, Walt inadvertently inoculated Norway spruce trees in his neighbor’s backyard with King Bolete. The inoculation occurred from spreading shavings and rinse-water outdoors, which he produced from mushrooms that he foraged and ate. Every summer, from under those Norway Spruce, he now harvests King Boletes where there where none before, under just three medium-sized yard trees! These pictures are from Walt’s iNaturalist observations, from this remarkable accident.


Indicator Species


We learned about “indicator species” for King Boletes. Fly Agaric Amanita muscaria mushrooms and ground-growing moss species including Delicate Fern Moss Thuidium delicatulum are good indicator species, if these are growing under host trees for King Boletes. These are used as rapid site compatibility clues by professional Tom Patterson, such that without ground-growing moss, a site is often not worth looking at.  Ian R. Hall has said “Boletus edulis is commonly found with Amanita muscaria… in China, England, New Zealand, and the USA, an association also noted… in France and…  in Austria. This may be because (Amanita) have similar ecological requirements and fruit at similar times of the year or it might reflect a biological association.” Tom said something like “When you see that Amanita muscaria is coming up in your King Bolete honeyholes, come back every three days to check for King Boletes.” Dr. Giovanni Gamba (University of Turin, Italy) told us about a Boletus edulis liquid mycelial inoculation for Castanea sativa (Myco Chest), which includes the edible Amanita caesarea. Mentioning edible Amanita should not detract from the “scare factor” of the deadly poisonous Amanita mushrooms that do exist, and which every forager should learn to identify and avoid. Take-away: King Boletes travel with Amanita mushrooms and ground-growing moss.

Timing Tips and Foraging for King Boletes on Abandoned Christmas Tree Farms

“The best months to forage for King Boletes in Southeast Ohio vary year to year. It depends on having enough rain (1-2 inches/week) and temps in the 80’s. On an average year, from best to worst: September, October, August, May/June, July.” -paraphrasing Homer Elliot

In May, these conditions occurred in Athens County, OH. With permission, we visited a 20+ year old Norway spruce planting, a commercial Christmas tree farm. We found Amanita muscaria had been flushing for week+, and that Boletus subcaerulescens was coming up.

Starting Chinese Chestnut seedlings, foraging King Boletes for inoculum

In late May & early June, Tom Patterson and Amy Miller shipped freshly foraged King Bolete mushrooms overnight to Thomas Lodge’s lab. Our specific mushrooms came from over-mature Christmas tree plantations in PA and a unique Chinese chestnut orchard that sits on a former oak woodland in OH. We have tentatively identified Boletus variipes from the OH site. Genotyping with bioinformatics analysis will be necessary to confirm this identification.

Thomas says that our King Boletes are successfully growing on the Petri dishes, see his video explanation here. Chris Smyth at Deer Orchard Nursery in Cincinnati has been watching the late-planted chestnuts begin to germinate. He tried a delayed germination technique to make the trees to order, such that the seedlings would not have been growing for very long before we could expect to see King Boletes in spring 2025. Chestnut seedlings started germinating but the germination rate to date has been much lower than when germinating chestnuts early in spring.

Chris built air-pruning beds and filled each with an autoclaved potting mix, and observed weed seeds germinate later. The pasteurization was not completely effective, as Dave Moore predicted. Soil is notoriously difficult to sterilize. Thomas says we could try a soil pasteurization wagon. Here are pictures of the potting mix, transported from by pickup truck in sealable, stackable plastic crates. You can see the freshly planted chestnuts in air-pruning beds, following methods from Perfect Circle Farm and Yellowbud Farms.

The potting mix was sourced from Nathan Rutz of Tilth Organic Living Soil. He designed this mix for us based on lengthy conversations about the need for some nitrogen in the form of dead organic matter, good water-handling capabilities, an acidic pH of less than 6.5, and reviewing the literature for what others had used. Others may raise their eyebrows at the addition of compost, but given the hard to predict nature about when our King Bolete inoculants would be ready, we decided that some rich compost could be an important source of nitrogen for ectomycorrhizal fungi to enzymatically break apart and disperse to chestnut seedlings.

Sand: 5%

Compost: 15%

Perlite: 20%

Pine Bark: 20%

Peat: 40%

Lesson Learned

With a goal of inoculating new chestnut seedlings, we should have developed the inoculant in sufficient quantity, and then autoclave the soil, and then germinate the chestnut seedlings at the first good opportunity. This order of operations would reduce the opportunity for other soil microorganisms to accidentally be introduced through the air into the autoclaved potting medium, and allow enough chestnut seedlings to be available simultaneously. Thus, we may delay inoculating chestnut seedlings until spring 2026, with a goal of germinating chestnut seedlings earlier in the spring.

A Mother Tree Site

Members of the team visited a Norway Spruce where Boletus edulis fruiting bodies have come up the last few autumns to assess where chestnut seedlings could be planted for the “mother tree method” of inoculation. The type species of the King Bolete genus- B. edulis– is said to almost exclusively fruit under Norway Spruce in North America, but fruits in association with virtually every deciduous and coniferous tree species in Europe except European larch. Why it would be host-specific on one continent and generalist in the US is an area of research for the Dentinger Lab.Interestingly enough, B. chippewaensis, which is found under some hardwoods, turns out to be genetically identical to B. edulis despite appearing phenologically distinct!

Dr. Dietrich Epp Schmidt shared a summary of where the project is at, more broadly.

“Scientifically, we’re still a long ways away from being able to say anything definitive about inoculating chestnuts with King Bolete based on our own experiment. But, there’s a lot of learning that has already shaped the project. There are a few key insights that surfaced during our proposal writing, and which I found to be exciting. First, our back of the envelope calculation suggests that during good years the market value of the King Bolete yield could easily eclipse the market value of the chestnut crop. This is a huge benefit to the farmer! Our proposal is focused on providing an incremental improvement to farm financial viability by increasing the growth rate and resilience of seedlings, thereby (hopefully) decreasing the time to market by a few years for newly planted orchards. However, the economic value of the mushrooms themselves offers a long-term vision of multiple revenue streams for the farmer from one cropping system. We love to see it!

Along the same lines, our proposal was focused on producing mycorrhized seedlings. However, we found evidence that suggests that it is likely that mature trees can successfully be inoculated, and that the development time for the mushrooms on mature trees is significantly shorter. If true, this is a huge development! It means that from the mushroom’s perspective, the main limitation for fruiting is having a tree partner that is able to supply sufficient carbon. From a production system perspective, it also means that mature chestnut orchards could also cash in on the King Bolete inoculants we develop, and start producing their own King Bolete. It further opens the possibility that we can develop the methods to inoculate mature hazelnut and pecan orchards with culinary mushrooms as well.”

Thank you to our sponsors, collaborators and fellow travelers. Please get in touch if you’d like to discuss this with us.

Woodland roses, invasive and native

We kill a lot of invasive multiflora rose. This organism was brought here by the USDA as a living fence species and escaped captivity. Living fences are better accomplished with trees grown in place, with any wire tacked onto a floating piece of treated lumber so that the wire doesn’t get swallowed by the radial growth of the tree. But I digress… Multiflora rose thorns have drained a lot of blood out of my body over the years, and the root exudate from this species is moderately allelopathic. You can see the lack of other plant species germinating seeding in under the rose as a result. It’s a bit yikes. 

I have been trying to teach people lately about our native woodland native roses, because I don’t want us throwing out the baby with the bathwater. Sometimes native roses are growing right next to invasive Rosa multiflora. It can be a little challenging to tell them apart until you compare the *stipule* on these plants, side by side.  A stipule is an outgrowth typically borne on both sides of the base of a leafstalk. There are good pictures of the stipules of native and invasive roses here- once you see the cilia coming off the sides of the invasive roses, vs. the “peace fingers” coming off the native rose stipules, I think you’ll be able to reliably tell the roses apart! https://fieldbioinohio.blogspot.com/2011/06/some-ohio-roses.html

Chinese chestnut seedling mycorrhization with porcini

I am delighted to report that a SARE Farmer/Rancher grant which I submitted has been fully funded. The funding will go to a research project, where we’ll study a forest farming practice known as mycosilviculture. In particular, we are seeking to colonize the roots of a new orchard’s worth of Chinese chestnut seedlings, with a type of ectomycorrhizal fungus known as King Bolete, aka porcini. The relationship between porcini and chestnut is already a mutualism that occurs in nature and also spontaneously in some orchards in Europe and Asia. To our knowledge however, we will be the first chestnut growers in America to study this relationship, and certainly to induce it deliberately. We hope we can pave the way by thoroughly documenting our success in such a way that others could follow our methodology. Additionally, after validating our methods, we hope to offer shelf-stable inoculum, mycorrhized seedlings, and consulting services as part of our offerings. You can read more about the project here. Please reach out if you have questions or interest, we’d love to tell you more about what we’re up to.

Paradise Ecological Services offers mentorship opportunities

Since early 2024, I have been active in offering professional development training through Rising Appalachia. Besides the education, our group produced a satisfying, effective, holistic body of work in the form of projects completed- and projects ongoing! These things were summarized by Rising Appalachia’s staff in their latest newsletter (see below). These people learned a lot, and of them have been hired to continue contracting with our organizations on other projects.

It occurred to me to post this, not just to boost Rising Appalachia’s website and newsletter, but because it seems like there’s an ongoing opportunity to learn with us. I have never publicly stated that before now. Despite me keeping quiet about it, I have received requests from no less than three college students in the past month, asking for unpaid internships with me. After talking with them, I accepted all three as my interns because they are highly motivated and have career goals that align with the ethos of this company. So here’s my pitch. If you want to learn by doing and are willing to put in some sweat equity for your education in the arts of agroforestry and silviculture, contact me through this website. Send a cover letter and a resume, with persuasive information about how me teaching you would be a good use of my time, and what you hope to learn from me. I will expect you to demonstrate your familiarity with the information on this website.
