  • Pinto Bean

    Celebrated squirrel’s legacy lives on for visitors

    Apr 18, 2023 3:00 pm

    Pinto Bean, the beloved piebald squirrel that lived and died on the University of Illinois campus, is back. The squirrel’s taxidermied remains are now on display at the Forbes Natural History Building lobby, where visitors can see its rare gray and white coloration that attracted fans and followers at the university.

  • An eastern red bat.

    Project succeeds in increasing east-central Illinois bat population

    Oct 27, 2020 8:00 am

    Thirty minutes before sunset, Illinois Natural History Survey (INHS) scientists and volunteers set up chairs in the prairie grass at Coles County’s Warbler Ridge Nature Preserve, look up at the summer twilight sky, and wait for the bat show to begin. Soon, the bats emerge from their bat houses to feed and fly off into the night. A good showing of bats is exciting news for the scientists: bat-focused habitat conservation efforts have proven to be effective in attracting and nurturing bat populations, but this work can take time to pay off.

    30 years of data show spotted turtle communities are still vulnerable

    Aug 27, 2020 9:30 am

    Populations of the endangered spotted turtle in Illinois are holding up better than those in other states, based on 30 years of data at the University of Illinois. Still, only two populations remain, and the predictions are poor.

  • Scientists find new fungi at the bottom of the Great Lakes

    Jan 17, 2018 11:15 am

    Far beneath the hulls of sailing ships on the Great Lakes are sediment habitats active with what may one day prove to be a priceless treasure. University of Illinois scientists hope that freshwater fungi inventoried in a new study might potentially contribute to a future treatment for childhood cancer.

  • Survey shows species of marsh birds that decline when nearby cities thrive

    Sep 17, 2019 10:30 am

    Wading into the springtime muddy marshland, pushing aside a wall of plants taller than her head, ornithologist Anastasia Rahlin looks and listens for signs of black terns and yellow-crowned night herons. She plays a recording, waits 30 seconds, and listens for a return call. The species of birds that she doesn’t find in the marsh are the ones she doesn’t want scientists to forget.

    New atlas website maps crayfish locations across the U.S.

    Feb 9, 2021 1:30 pm

    Researchers at the Illinois Natural History Survey (INHS) have developed the new American Crayfish Atlas, the first website to provide nationwide coverage of crayfish distributions, showing where crayfish species have been found and the extent of their ranges.

  • Recent surveys find few of once-common bat species

    Sep 10, 2019 3:30 pm

    Bat species that used to be common in Illinois are scarce in recent surveys, sending up a red flag.

    Scientists call for global effort to monitor odonate populations

    Sep 22, 2020 10:15 am

    INHS ecologist Jason Bried and more than 30 co-authors published an article calling for a worldwide effort to monitor not just locations but also quantities of Odonata species.

  • Researchers suspect that nightjars are declining in Illinois

    Sep 25, 2017 1:45 pm

    Although the Eastern Whip-poor-will is rarely seen, its distinct call occasionally can be heard in forests from dusk until dawn. Once common, Whip-poor-wills and other nocturnal nightjar species are disappearing from Illinois forests as their habitats shrink and change, according to data from the Illinois Natural History Survey (INHS), a division of the University of Illinois’ Prairie Research Institute.

  • Illinois stream fauna: A look back at pre-settlement biodiversity

    Jan 16, 2018 9:00 am

    INHS researchers used species record data from INHS research collections, other museums, and trusted sources to model and predict the historical distributions of three main aquatic groups—freshwater mussels, stoneflies, and fish.

  • Turning the tables: Application of commercial fishing helps fight the spread of Asian carp

    Aug 15, 2017 10:00 am

    The Illinois Department of Natural Resources (IDNR) is using federal funding from the Great Lakes Restoration Initiative to help Illinois’ commercial fishermen suppress the exploding invasive carp population. The project—which brings together multiple agencies and Illinois universities, including the Illinois Natural History Survey and the University of Illinois—is a complex undertaking involving the newest technology in bubble, sound, and electric barriers and fish-counting sonar, coupled with centuries-old stalwarts such as gill nets.

  • Bass learn from experience not to take the bait

    Sep 27, 2019 2:15 pm

    Largemouth bass apparently don’t learn to avoid fishing lures from other bass but instead from their own past experiences, according to University of Illinois research.

  • Researchers describe crayfish conservation concerns and strategies

    Jan 30, 2020 8:45 am

    Whether you call them crayfish, crawfish, or crawdad, this creature needs protection nationwide to prevent extinction, according to Chris Taylor, Illinois Natural History Survey curator at the University of Illinois. In a recent article published in the journal Hydrobiologia, Taylor and colleagues have outlined possible strategies for conservation practices to protect crayfish from invasive species, habitat changes, and potential overexploitation.

    Researchers find that data from hunters can help assess bobcat population

    Jun 11, 2020 12:00 pm

    Wildlife managers track animal groups to control populations and determine the number of permits provided to hunters and trappers each year. Whether data are taken from the forest or from hunter surveys, their accuracy is necessary to inform conservation, according to Javan Bauder, post-doctoral researcher at the University of Illinois’ Illinois Natural History Survey.

  • Scientists foretell the fate of Illinois’ threatened and endangered plants in a changing climate

    Oct 11, 2019 8:00 am

    Scorching summers are predicted for Illinois’ future, threatening already vulnerable plant species. University of Illinois scientists have presented a new way to prioritize restoration efforts, not necessarily focusing on the most precarious plants.

    Chronic wasting disease in Illinois: resources and disease dynamics

    Sep 13, 2017 5:30 pm

    Protecting the deer herd from chronic wasting disease has economical value to the State of Illinois, recreational value to deer hunters, and a health value for CWD-susceptible animals. Currently, there is no treatment or vaccination against CWD. Management based on removal of infected deer in areas where disease is present is the only known strategy to control the spread of CWD.

  • Exploring personality effects in largemouth bass

    Nov 16, 2017 10:00 am

    INHS studies have shown that largemouth bass have distinct personalities and that these different types affect predator-prey interactions and possibly habitat use. The explorers tend to have a relatively indiscriminant diet, consuming any prey they encounter, while non-explorers discriminate in their diet selections, focusing on the most profitable prey items. 

  • Zebra finch study finds mixed impact of early-life stress

    Jun 19, 2017 10:45 pm

    A bout of early-life stress can have lifelong impacts on two key signals that help male zebra finches attract mates: beak color and song complexity. But rather than being uniformly negative, a recent study published in Functional Ecology found that the consequences of stress are mixed. Stressed males wind up with duller, less colorful beaks but sing more complex songs.

  • Owls eat roadkill, research finds

    Nov 18, 2019 9:30 am

    Owls have never been known as scavengers that eat decaying flesh, but the behavior is more widespread than once believed, according to University of Illinois researchers at the Illinois Natural History Survey (INHS) who photographed owls scavenging in the night.

    Assessment of Asian carp in Illinois waterways

    Sep 5, 2019 9:30 am

    Scientists and policymakers have long struggled with managing Asian carp numbers in Illinois waterways. PRI's Joe Parkos and Steve Butler explain what's working to scale back these intruders as they inch toward the Great Lakes.

  • Hear the Sound of Owls Calling at Night

    Oct 24, 2016 8:00 am

    “Birds of omen, dark and foul,” wrote Sir Walter Scott about owls, once considered harbingers of doom, death, and destruction. In Medieval Europe, owls were thought to be witches and an owl's call meant someone was about to die.
