The Birds of America: The Bien Chromolithographic Edition
When Joel Oppenheimer recognizes a bird, it’s not because he’s a birder, but rather because the renowned art dealer has been intimately acquainted with the quintessential avian paintings of John James Audubon for decades.
Now, Oppenheimer, one of the country’s foremost authorities on Audubon, has produced and written “The Birds of America: The Bien Chromolithographic Edition.” Oppenheimer has written text to complement the first complete reproduction of the Bien chromolithographs: 150 full-color illustrations in facsimile form of “The Birds of America,” which Audubon painted more than 150 years ago.
Oppenheimer, a Chicago-based art dealer and art conservator, will give a free talk about this seminal project at 7:30 p.m., June 18 at Brushwood Center, 21850 Riverwoods Road, Riverwoods, Illinois.
Through his seven years of research and working with publisher, W.W. Norton and Co., Oppenheimer discovered some intriguing information, not so much about John James Audubon himself, but about his wife, Lucy, and their son, John Woodhouse Audubon.
After Audubon’s death, his son commissioned Julius Bien in 1858 to produce a new edition of his father’s works with a revolutionary chromolithographic process that omitted the painstaking steps of hand coloring each piece as had been done previously.
The family still owned the original paintings and all the original copper plates.
“The family put everything into this,” Oppenheimer said. “Lucy Audubon mortgaged their estate to finance the project. When the Civil War came, however, the project could not be completed and the family suffered a devastating bankruptcy.” Audubon’s original watercolors were sold to the New-York Historical Society in 1863.
Only 150 plates were produced in the Bien collection. They are among the rarest and most sought-after Audubon prints. When Oppenheimer secured a complete folio of the Bien collection about eight years ago, he was inspired to produce the new book.
“There was something about the quality of this printing that captured my imagination,” he said. “In previous writings, the Bien edition had been cast aside and much maligned as being a poor quality reproduction. I bought this set and it was an exquisite example of chromolithography and Audubon’s work.”
Oppenheimer said his new book “is a very specific treatment of one particular edition of Audubon’s work that had never been examined in depth at a scholarly level. There’s a lot of new information in the book, a lot of discovery from original research.”
The June 18 event is presented through a partnership between Brushwood Center and Lake County Forest Preserves. A limited number of books will be available for purchase ($350) and signing. A portion of the proceeds will benefit Brushwood Center. To reserve your copy in advance, call 847.968.3308. Registration is required. To register, call 847.968.3321.
WHEN: 7:30pm, Wednesday, June 18
WHERE: Brushwood Center, 21850 N. Riverwoods Rd., Riverwoods, IL
Registration required. To register, call 847.968.3321.
On the heels of the release of his highly anticipated second edition of The Sibley Guide to Birds, David Sibley will speak and sign books from 7:00 to 8:00 p.m., April 9 at Ryerson Woods. The book talk will take place in the Welcome Center, 21950 Riverwoods Road, Riverwoods, IL. The event is free and open to the public. Registration is required.
Sibley, preeminent birder, author and illustrator, will talk about his work to expand and update his bird guide published in 2000. The second edition, just released, offers new paintings, new and rare species and copious updated information sure to astound bird lovers of all levels. The second edition also includes nearly 7,000 paintings, and all illustrations reproduced 15 to 20 percent larger for better detail.
Sibley will talk about his research out in the field and in museums to gather information he said has made his second edition more accurate and more useful to birders. The cover features the Magnolia Warbler, a bird Sibley recalls seeing first when his father, ornithologist Fred Sibley, banded it near the Point Reyes Bird Observatory in California. It’s one of many birds that will be migrating through the Chicago and suburban area in May.
Sibley’s book has been called “the finest guide to North American birds.” He is a contributing editor to BirdWatching Magazine and author and illustrator of many other books about birds. He last visited Ryerson Woods as keynote speaker of the 2003 Smith Nature Symposium. He spoke to a sold-out crowd.
Do you know about Project Passenger Pigeon (P3)? It is an international effort to mark the 100th anniversary of the passenger pigeon’s extinction in 2014. Friends of Ryerson Woods is a P3 partner.
The passenger pigeon was once the most abundant bird in North America and likely the world, with a population that likely exceeded a billion as late as 1860. But because it was the cheapest terrestrial protein, it was subjected to unrelenting exploitation that drove it to near extinction by the first few years of the twentieth century when the last wild birds were shot. All that remained were a handful of individuals in captivity, the last of which (Martha) keeled over in her cage at the Cincinnati Zoo on September 1, 1914.
The story of the passenger pigeon has great relevance to us today. There is no better cautionary tale to the proposition that no matter how abundant something is, be it inanimate ―water, oil, etc.―or alive, it can be lost if we are not circumspect in our use. P3 seeks to familiarize the public with the story of the passenger pigeon and then to make the connections with current issues related to extinction and our place in nature. P3 intends to do this through its web-site, social media, curriculum, a book, and a variety of exhibits and programs. Friends of Ryerson Woods has adopted the centenary as its 2014 theme, and we are developing a rich slate of public programs for 2014 that explore the themes of extinction and species survival. We are partnering with other Lake County organizations to present a wide range of activities, exhibitions and presentations for you to enjoy throughout the year.
One program you won’t want to miss is a book talk by natural history historian and author Joel Greenberg. Joel has written the first comprehensive book on the passenger pigeon in 50 years. It is being published by Bloomsbury USA and will be released early in 2014. We’ve secured Joel for an author event on Thursday, February 20, 2014 at 7pm. This event will be held at the Greenbelt Cultural Center and is being presented in partnership with Lake County Forest Preserves, Lake Forest College, Lake Forest Open Lands and the Wildlife Discovery Center. Copies of Joel’s forthcoming book, Feathered River Across the Sky: The Passenger Pigeon’s Flight to Extinction, will be available for sale and signing.
The single element that can reach the most people is the documentary being made by director David Mrazek, “From Billions to None.” It is also the most expensive element. As such, P3 recently launched an Indiegogo crowd funding campaign and has already raised $22,000 of its $65,000 goal. These funds will allow for additional animation, trips to significant sites, production assistance, and other important tasks. We’d love to be able to screen this film for you in 2014. Would you be interested in supporting the production of this important film?
Ryerson Woods is a magical, natural wonderland in the spring – full of native flowers covering the forest bed, trees as far as the eye can see and a host of beautiful creatures living inside. This past Saturday at the 30th annual Smith Nature Symposium, a new and delightful figure appeared in the woods. “Bird Girl” welcomed guests to the symposium in a dress made of moss, hand-painted birds, butterflies and flowers.
Celebrating 30 years is a special occasion and we knew we needed something equally special to dazzle our guests. I thought about a garden dress I came across some time ago. Cascading rows of planters made up an elaborate and dramatic piece of art and nature, the very intersection we cross with our mission at Friends. Many of the events I have done in the past have had a performance artist or some artistic feature to wow guests so I approached our group to see if we could do something similar.
With a passion for design, the project sparked the interest of Friends of Ryerson Woods administrative coordinator and multi-media artist Julia Kemerer. She quickly came up with a concept and got to work.
The hardest part was manipulating chicken wire to form the lower half of the dress and covering it with natural materials, such as Spanish moss, green mountain moss and Black Lichen. Poor Julia was covered in cuts and scratches, as well as the materials and glue. It was a labor of love, though, because it ignited her creative spirit and she was able to focus her energy into a project close to her heart.
Guests were tickled to see the finished product and enjoyed taking pictures with “Bird Girl” throughout the night. Her hat, adorned in hand-painted eggs atop a gorgeous nest, balanced delicately on her head as she made her way through the party interacting with guests. She then rallied the crowd to raise their paddles for fundraising.
It was an incredible evening, made possible by so many great moments and helping hands. Kenn Kaufman delivered an informative and funny keynote address. Sophie Twichell, executive director at Friends, lovingly honored longtime friend and former colleague Doug Stotz, the 2013 conservation award winner. Last, and certainly not least, the Lake County Forest Preserve District worked tirelessly to take care of setting up, providing staff and volunteers, chauffeuring guests to the front door and so much more. We couldn’t do it without you!
Thank you to all involved to help make this a memorable year!

Friends of Ryerson Woods hosted a panel discussion on “The Hidden World of Wolves and Coyotes” in November 2012. Afterwards, our executive director, Sophie Twichell, was invited to write an article on misconceptions about coyotes for the Lake Bluff Open Lands Association’s newsletter. We thought our readers might be interested in this information as well. Let us know if you learned something new after reading the article. Enjoy!

Do you hear coyotes howling at night? See them trotting down the sidewalk or crossing streets? Without a doubt, coyotes are active members of our North Shore communities. But, how much do we really understand this medium-sized member of the dog family (along with wolves and foxes)? Coyotes are often misunderstood, as well as underappreciated for the valuable role they are playing. Learning more about these elusive creatures is the best way for us to live harmoniously with coyotes.
Coyotes, Canis latrans, are native to North America and currently occur throughout most of the continent. Their historical range prior to 1700 was restricted to the prairies and desert areas of Mexico and central North America. But over the past few centuries, coyotes have dramatically expanded their range across North America and now are found in an increasing number of cities in the United States and Canada. In addition to occurring in natural areas, coyotes are also found in a range of human-populated areas, including rural farms, suburbs and cities.
Stan Gehrt, Ph.D., Associate Professor in the School of Environment and Natural Resources at Ohio State University, has been leading a team of researchers studying urban coyotes in the Chicago metropolitan region since 2000. Gehrt’s team has caught and marked 661 coyotes, including radio collaring 379. He recently shared fascinating facts about coyotes with 200 curious community members at the Greenbelt Cultural Center in North Chicago at an event sponsored by Friends of Ryerson Woods and Conserve Lake County.

Here is a sampling of what Gehrt’s team has discovered about coyotes on our region:
– Most adults weigh between 25-35 lbs. A few big ones weigh in the 42-43 lbs. range. There are no 50 lb. coyotes.
– They have individual personalities. Some are shy, others aggressive. Some howl often, others hardly at all. Individual variation is tremendous.
– Packs are made of family members and are very territorial.
– Howling is a way to bring family members together, as well as to establish territory; it is not a sign of aggression or hunting.
– Coyotes are monogamous for life; pairs only split upon the death of a mate.
– The average litter size is 4-7 pups, although can range from 3-15.
– Male coyotes help raise the young just as much as females.
– February is the peak of mating season for coyotes; litters are born in April.
– During mating and gestation is the only time coyotes will voluntarily use a den (a burrow in the ground or hollowed out tree); otherwise, coyotes usually sleep above ground in the open or in cover.
– In captivity, coyotes can live 13 to 15 years, but in the wild, most die before they reach three years of age. Gehrt’s study found that coyotes generally have a 60 percent chance of surviving one year.
– Coyotes inhabit virtually every green space of any significant size throughout the Chicago metropolitan region; if they are removed, new ones will move right in.
– Coyotes in the Chicago metropolitan area confine most of their activity to nocturnal hours, whereas in natural areas, coyotes tend to be diurnal (active during the day) or crepuscular (active at dawn and dusk). This reduces the likelihood of interacting with humans.
– Coyotes are incredibly adaptable. Gehrt showed video of coyotes crossing city streets and even interstates safely, apparently looking both ways before crossing the street and following green lights.
Much controversy revolves around what coyotes eat. Gehrt’s study has provided fascinating information, including some unexpected results. A study of coyote scat (poop) revealed that the most common food items are small rodents (42 percent), fruit (23 percent), deer (22 percent), and rabbit (18 percent). They also will eat birds, frogs, skunks, insects and the occasional beaver or muskrat. Apparently the majority of coyotes in the region do not, in fact, rely on our pets (1%) or garbage (2%) for their diets. (Scats often have more than one diet item; therefore, frequencies do not necessarily add up to 100 percent). As coyotes need to eat about 10% of their body weight each day, this preference for rodents can result in a diet of 3,000 rodents per year! Further, coyotes serve as the primary predators on fawns. One surprising find was that coyotes control Canada Geese populations by eating the eggs. Geese parents can fight off raccoons but not coyotes. 97% of goose nest predation is carried out by coyotes. Geese and deer are often overabundant and difficult to manage. Thus, coyotes play a key role in naturally controlling rodent, deer and geese populations.
But, what about our pets? There are a few things to consider. It is natural canid (dog family) behavior to kill smaller canids. This is about instinct and survival. Given the opportunity, wolves will kill coyotes, coyotes will kill fox, and so on. This is less about getting a meal, but instead about eliminating competition. So, you want to keep an eye on your small dogs. Coyotes also may kill domestic cats for food or again to eliminate competition, but Gehrt’s study reveals that cats make up a very small part of their diet. Also, other predators eat cats, including Great Horned Owls. If coyotes live nearby, do not let pets run loose, especially domestic cats. When hiking in preserves, keep dogs on leashes.
In general, coyotes will avoid humans. Considering how many live around us and how few incidents we actually have with coyotes, it is clear they are staying out of our way. But, there are many ways we can minimize the possibility of conflicts with coyotes. Most important is not to feed them. Many people unintentionally feed coyotes by leaving pet food or garbage out at night or by having large bird feeders. Coyotes are generally not interested in bird food, but bird feeders often attract rodents, especially squirrels, which then attract coyotes. Although coyotes seem to have a natural inclination to avoid human-related food, this can change when prey populations are low, or if the coyotes are young and haven’t yet learned to hunt effectively. If you encounter one or more coyotes on a trail, do not run away. It is part of canid (dog family) instinct to chase something that flees. That is how they chase down prey. Instead, you should make a lot of noise, as well as throw something at them.“Coyotes in the Chicago area are successful in spite of us, not because of us,” Gehrt contends. “They eat their own food, not ours. They hunt as if we weren’t even here. They do their best to avoid us.”
FIVE EASY STEPS TO AVOID CONFLICTS WITH COYOTES
Conflicts with coyotes can be avoided by taking simple precautions or by altering behaviors to avoid confrontation:
