    The first full weekend of every month, the Nature Museum becomes a herpetologist haven! That's when the Chicago Herpetological Society sets up tables in the Nature Walk for some reptile fun with the public and the Junior Herp Society holds their monthly meetings! The Notebaert is an awesome and beautiful place to go and reconnect with nature during these colder months.

    The Chicago Junior Herpetological Society is about sharing the love of amphibians and reptiles with the younger generation, and fostering an appreciation of wildlife and nature through educational speakers and hands-on interaction.

    The regular monthly meetings of the Chicago Junior Herpetological Society take place at The Peggy Notebaert Nature Museum, on the Sunday of the first full weekend every month, from noon till about 1:30. Meetings are free to visitors to the museum. We are sad to announce the cancellation of the April 5th meeting as scheduled. We made an error in planning and did not see that this will be Easter Sunday and many of us have other plans that day. We have some friends at the Brookfield Zoo and they generously helped us to arrange a behind-the-scenes tour for the kids there on Saturday, April 4th. We had good response to this and it should be fun. The next meeting will be on Sunday, May 3rd. Our scheduled speaker is Matt Bordeux and he will be discussing field herping, which is the observation of these animals in their natural habitat. We are looking forward to this an we are also planning a trip out to Channahon, IL to do some actual field herping with last month's speaker, Ranger Kevin Luby from the Willowbrook Wildlife Center on May 30th.

    The Chicago Herpetological Society is a non-profit all volunteer organization dedicated to the conservation of all wildlife, especially reptiles and amphibians, the cooperation of amateur and professional herpetologists toward a more complete understanding of herpetofauna, and the education of the general public about these often misunderstood but fascinating animals.​

    When considering getting a new pet for the family, a great option to consider is adoption. There are many awesome animals out there in need of a loving home. The CHS has an adoption program available to members. There are currently some awesome animals being fostered and ready for a new forever home. Contact Colleen Schwarz or Linda Malawy of the CHS adoption program.

    You can learn more about CHS adoptions here.

    The Junior Herp Society was founded by members of the Chicago Herpetological Society and we encourage our members to become members of the CHS as well. General meetings of the Chicago Herpetological Society are held on the last Wednesday every month at 7:30pm at the Notebaert. Meetings are free to attend. This month's meeting will feature guest speaker Danny Mendez. He'll be discussing Raising Ethical Standards in Herpetoculture.

    We regret to announce the cancellation of ReptileFest 2015, which was planned for April 11 and 12, due to a cancellation of our venue due to unforseen circumstances. We are currently working on the best possible venue for ReptileFest 2016 and we hope to make this better than ever.

  • Meet the "Rainforest Adventure" Critters

    Created: 11/17/2014      Updated: 8/24/2015


    One of the most exciting parts of our newest exhibit Rainforest Adventure, is the added element of having live animals as an intricate part of the experience. Just what are these animals? Read on to find out! 

    Blue-Throated Macaw

    blue-throated macaw

    Upon entering Rainforest Adventure, the first beautiful bird you’ll encounter is Iggy, our Blue-Throated Macaw. This species of macaw is critically endangered. Population estimates vary, but it’s believed that there are between 50 to 400 individuals living in the wild. Blue-Throated Macaws are also far more threatened than their Blue and Yellow Macaw cousins. While the two look very similar, Blue and Yellow Macaws actually have green feathers on the crown of their heads (instead of blue) and black feathers on their throats (instead of blue). Though their habitats are threatened, they’re typically found in Northern Bolivia and can live 30 to 35 years in captivity.

    Violaceous Turaco

    violaceous turaco

    Also known as the Violet Turaco or the Violet Plantain-Eater, Violaceous Turacos are typically found in West Africa. Their feathers are a distinctive, glossy violet color, which appears in stark contrast in addition to their red, white and yellow heads and bright orange bills. If you visit Rainforest Adventure, you’ll probably notice that our Turaco is quite active and has a distinctive call.

    Spectacled Caiman

    spectacled caiman

    These small to mid-size crocodilians are typically found in Central and South America, and is actually the most common crocodilian due, in part, to its ability to tolerate both fresh and salt water. Their name comes from the bony ridge that is present between their eyes and gives the appearances of glasses. Our Caiman isn't alone, though. Stop by and you'll probably see the Caiman and an African Mud Turtle soaking side by side.

    Powder Blue Poison Dart Frogs

    Poison Dart Frogs, in general, typically measure from half-an-inch to two-and-a-half inches in length. Although their skin produces toxins that can be dangerous when ingested, they don’t synthesize the poison themselves. Instead, they obtain it from what they eat, like ants and centipedes, meaning that the frogs that are raised in captivity don't have these toxins present in their systems. Powder Blue Poison Dart Frogs tend to be larger than most other species of Poison Dart Frogs. Typically, their bodies are primarily black, with an irregular pattern of yellow or white stripes running along their back, flanks, chest, head, and belly. Their legs range from pale blue, sky blue or blue-gray to royal blue, cobalt blue, navy blue, or royal purple and are typically spotted with small black dots. 

    Frogs kindly loaned by Tundra Exotics and the Chicago Herpetological Society.

    Green Tree Python

    green tree python

    Green Tree Pythons are typically found in Southeast Asia and Australia. They are often seen in a position known as saddling, as our beautiful python illustrates in the photo above. In saddling, the snake coils its body and lays it over the branch in a saddle position, with tits head placed in the middle. Although it’s visually similar, it shouldn’t be confused with the Emerald Tree Boa which is typically found in South America. They are actually only very distantly related.

    The first full weekend of every month, the Nature Museum becomes a herpetologist haven! That's when the Chicago Herpetological Society and the Junior Herp Society hold their monthly meetings, and invite the public to join in on the fun. What is the Herpetological Society? In this post, the Chicago Herpetological Society's Rich Lamszus introduces us to it.

    The goal of the CJHS is to establish a learning environment where younger kids are mentored by older kids with knowledge of reptiles and amphibians, under adult supervision, in the beautiful museum setting. The regular monthly meetings of the Chicago Junior Herpetological Society take place at The Peggy Notebaert Nature Museum, on the Sunday of the first full weekend every month, from noon till about 1:30. Meetings are free to members of the CHS and visitors to the museum. 

    The next meeting will be on November 2 and will be our second anniversary meeting. Our speaker will be Yvette Mendez and her topic will be Reptile Parents and Reptile Babies. Colleen’s Critter Corner will feature frilled lizards and blue tongued skinks and differences in keeping them. 

    You can learn more about the CJHS here.

    Visitors as Junior Herp Society meeting

    The CHS, established in 1966, is made up of hundreds of people who love reptiles and amphibians and want to do what they can to help other people understand this not-so-mainstream devotion. From encouraging the public not to fear snakes, to helping someone learn how to take care of her brand new gecko, we are spreading knowledge and spreading compassion for these creatures who are so often labeled in a negative way. We welcome anyone who shares our passion to join us! General meetings of the Chicago Herpetological Society are held on the last Wednesday every month at 7:30pm at the Notebaert, with the exception of Christmas Eve this year. Meetings are free to attend. 

    The next meeting on October 29 will feature news and announcements, an awesome raffle and our speaker will be Chris Gillette. The topic will be “Behavior of American alligators and crocodiles in captive and wild situations”. We are also gearing up for next year’s ReptileFest, the nation’s largest educational herpetological event. ReptileFest 2015 will be on April 11 and 12, from 10am to 5pm in the University of Illinois Phys Ed building. Mark your calendars, this will be the 22nd year of this wonderful show. You can learn more about the Herpetological Society here, and learn more about ReptileFest here.

  • Frog Facts and Toad Tidbits

    At the Peggy Notebaert Nature Museum, volunteers feed different groups of animals on different days as part of public interpretative programs (PIP). Recently, to keep things fresh for volunteers and visitors, the schedule was shuffled, and now aquatic animals are fed on Monday, fish on Tuesday, Blanding’s turtles on Wednesday, water snakes on Thursday, box turtles on Friday, and endangered turtles on Saturday.

    And on Sunday, frog and toad feeding takes place in the Look-in-Lab, where the volunteers offer crickets by hand or tweezers to the anurans in tanks along the viewing window. (Frogs and toads belong to the order of amphibians called “anura” so collectively are referred to as “anurans.”) The session is entertaining for visitors; they laugh when a volunteer involuntarily jerks her hand back as the critter grabs mouth first for its meal (you tell yourself not to, but it is a reflex that is hard to overcome), and they applaud when the critter gets the cricket. To make the feeding educational as well, other volunteers stand on the public side of the window to provide visitors information about frog and toad diets and habits.

    Frogs and toads are usually sit-and-wait predators, relying on camouflage to hide their motionless bodies until an unsuspecting potential meal moves within reach of a lunge and “lingual flip:” the tongue flips out and slaps on the target and then flips back with the prey stuck on. This capture technique is made possible by a tongue that is attached to the front of the jaw and free at the back (unlike those of humans and other animals) and by a gummy mucous exuded at the instant of contact. Thus, the anuran tongue does not shoot out like the tongue of a chameleon or a cartoon frog. The whole action takes less than 15/100ths of a second, faster than our eyes can follow. Below is a cool, slow motion video of a leopard frog flipping up a waxworm with its tongue.


    Frogs and toads have teeth but only along their upper jaws. Their teeth are weak and are not used to chew or tear, but to hold prey before it is gulped down whole. Their eyes help anurans swallow their meals; an emphatic blink presses their eyeballs through holes in the skull, pushing food down the throat.

    Cricket Frog

    Most frogs and toads eat insects, spiders, worms, larvae, and slugs, although larger species may also eat small birds, reptiles, or amphibians. Every two to three weeks, the Museum orders 2,500 crickets (1,000 small, 1,000 medium, and 500 large) -- between 65,000 and 44,000 a year. They are fed not only to the frogs and toads, but also to the Museum’s salamanders, some turtles, aquatic insects, and spiders.

    The Museum has 12 species of anurans, all also found wild in Illinois: Fowler’s toad, American toad, pickerel frog, green frog, leopard frog, plains leopard frog, chorus frog, cricket frog, wood frog, green tree frog, Cope’s tree frog, and gray tree frog.
