  • Southern White Pelicans at Rend Lake in large numbers

    INHS Ornithologist T.J. Benson was featured in an article about the Southern White Pelicans currently being seen in large numbers at Rend Lake. Unlike the Brown Pelicans, which dive into the water for food, White Pelicans align themselves in a circle and scoop up the fish. Benson stated that in the spring the birds might migrate through more quickly needing to get to the breeding grounds, the fall migration can be more spread out, with birds lingering in places with good resources. Asked about the number of birds, he stated that "Anecdotally, you're definitely seeing more and more. It's kind of true that wetland birds in general are tending to do better over time. Some of that is habitat restoration and cleaning up waterways."

  • Mentors help Illinois students learn to hunt at workshop

    Seventeen University of Illinois students developed their hunting skills at a free two-day workshop at Allerton Park in September. The workshop was part of a statewide program developed by the Illinois Natural History Survey with support from the Illinois Department of Natural Resources; the goal is to encourage more Illinoisans to participate in hunting, an activity important to both the economy and ecosystems of Illinois.

  • The Field Guide to the Sphinx Moths of Illinois is available!

    Though often overlooked, there are more than 60 species of Sphinx Moth in Illinois.

  • Researchers find that data from hunters can help assess bobcat population

    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.

  • Research on diving ducks continues

    Researchers at the INHS Forbes Biological Station have banded lesser scaup over the past two seasons to examine their use of restored habitats. Director Heath Hagy hopes to have funding to continue taking blood samples to look at metabolites and contaminants in the birds. “There are a lot of scaup here,” Hagy said. “We are catching 200-400 per day and we are only getting 10-20 recaptures, so there are a ton of birds out there."

  • Most Mussels Survive River Relocation

    Relocating freshwater mussels from the path of a bridge construction site to a safer zone upstream is proving to be a time- and cost-effective conservation practice. Mussel survival rate after relocation is high, according to new research from the University of Illinois’ Prairie Research Institute (PRI).

  • Skunk cabbage—Illinois' earliest native flower

    INHS Botanist John Taft and Outreach Coordinator Jen Mui were quoted in an article in the Chicago Tribune about skunk cabbage. Skunk cabbage, Illinois' earliest flowering native plant, gets its name from the foul odor produced as it generates heat. The heat and odor attract pollinators including flies, carrion beetles and honey bees. A link to a video about skunk cabbage pollination produced by the Outreach Department was also included in the article.

  • Butterflies of Illinois field guide is now available from University of Illinois Press

  • Danville, crow capital of the world

    INHS Ornithologist Steve Bailey told the Chicago Tribune that Danville has "the largest winter roost of crows that we know about in the U.S. and Canada." Christmas Bird Counts found 121,500 crows, whereas a year ago, the count was 238,000. INHS Affiliate Mike Ward added that the drought caused a resurgence of West Nile virus, to which crows are particularly vulnerable. Crows rebound well, which might be bad news for the residents of Danville who have unsuccessfully tried many things including trucks with a "cannon" booming to scare the birds.

  • Dr. R. Weldon Larimore, in memoriam

    Richard Weldon Larimore, long-time aquatic biologist of the Illinois Natural History Survey (INHS), died on January 14, 2015 at Urbana, Illinois. He was 91. He is survived by his wife Glenn E. Larimore and three sons Richard L., Kenneth, and Michael Larimore.

  • Loss of our colleague Arlo Raim

  • Hospitable Illinois wetlands in spring signal happy waterfowl hunting in fall

    When waterfowl return to Illinois in early spring on their way north, will they find enough food for a two-week layover? A limited food supply during spring migration and subsequent declines in duck populations can affect Illinois’ multi-million-dollar waterfowl hunting industry, say researchers from the University of Illinois’ Prairie Research Institute (PRI).

  • Illinois Natural History Survey takes campus lead on bird awareness

    After years of collecting dead birds at the Forbes Building, some of the INHS staff decided to find a solution to modify the large windows that were causing so many avian deaths. After consulting with the University of Illinois’ Architectural Review Committee (ARC), staff chose an Acopian Bird Saver for the south windows and a lined window film for the north windows where most of the bird casualties occurred.

  • Study Finds Illinois Farmers View Feral Hogs as a Nuisance

    Illinois farmers, even those who have experienced no damage to their land or crops, dislike feral hogs and support hog control, according to a new study from the Illinois Natural History Survey (INHS), Prairie Research Institute, University of Illinois.

  • Rare shrimp found in Des Plaines River

    INHS Astracologist Christopher Taylor and INHS Ichthyologist Emeritus Larry Page were interviewed about an unusual animal found during aquatic surveys in Lake County in NE Illinois. Lake County Forest Preserve staff turned up a "Palaemonetes kadiakensis," glass shrimp or Mississippi grass shrimp, whose range is typically further south. Taylor said that there are only five species of freshwater shrimp in North America and this particular species has adapted to live further north than the others. Page added that this species is usually found in cleaner streams, so this could be a good sign for the health of Des Plaines River.

  • Migratory birds bumped off schedule as spring shifts

    New research shows climate change is altering the delicate seasonal clock that North American migratory songbirds rely on to successfully mate and raise healthy offspring, setting in motion a domino effect that could threaten the survival of many familiar backyard bird species. A growing shift in the onset of spring has left nine of 48 species of songbirds studied unable to reach their northern breeding grounds at the calendar marks critical for producing the next generation of fledglings, according to a paper published on May 15, 2017, in Scientific Reports. The Illinois Natural History Survey was one of several institutions contributing to the study.

  • Uncovering the mystery of Kirtland's snakes

    The Kirtland's snake is shy and secretive, and, as a result, not a lot is known about it. A group of researchers is working hard to change that. They're developing a better understanding of this small but beautiful snake that is widely scattered in small enough numbers to put it on Illinois' threatened species list.

  • Study Finds Waterfowl Hunters’ Spending Benefits Rural Areas

    Guns, gear, gas for the truck, drinks for the cooler, and the faithful dog: such recreational expenses for a day of duck or goose hunting in Illinois add up to a big boost to the local economy, according to Craig Miller, human dimensions scientist at the University of Illinois’ Prairie Research Institute.

  • Greg Sass discusses Silver Carp and electric fish barrier

    Greg Sass discusses silver carp and the electric fish barrier In a January 9, 2009 article in the Milwaukee Journal Sentinel. The article focuses on the impediments to the electric barrier that is supposed to protect Lake Michigan from invasive species moving through the Chicago Sanitary and Ship Canal. Silver carp, like Asian carp, is an invasive fish threatening the Great Lakes. Greg Sass, INHS Illinois River Biological Station Director, said that silver carp 'accounted for more than 50% of the catch' during 18 weeks of sampling last summer. The full-text of the article can be found on the NewsBank website: Fish fence may get turned on this month But Asian carp barrier for Great Lakes would be at just 25% power

  • Be A Hero - Transport Zero campaign to stop the spread of exotic species wins award

  • INHS researching snakes at Allerton Park

    Jon Griesbaum, a student in Dr. Christopher Phillips lab, is studying the movements of Fox Snakes at Allerton Park using radio telemetry. The snakes that are captured and marked are then tracked for a year. Griesbaum hopes that learning more about the snakes range and behavior will enable policy makers to make informed and better choices about wild areas. Articles about Griesbaum's study appeared in the 7 September issue of the News-Gazette, the 4 September issue of Environmental Almanac, and can be found archived.

  • Juvenile Bighead Carp more vulnerable to predation

    INHS graduate student Eric Sanft, presented "Vulnerability of Juvenile Asian Carp to Predation by Largemouth Bass" at the recent Midwest Fish and Wildlife meetings. His research found that bighead carp are more susceptible than other carp species to predation by largemouth bass. Read more about Asian Carp research from our Kaskaskia River Biological Station.

  • Invasive species of honeysuckle cause big problems

    INHS plant ecologist Greg Spyreas was cited in an article about invasive bush and Japanese honeysuckle. Based on his previous research, establishment of Japanese honeysuckle decreases the value of an area for wildlife by crowding out native plants. These invasive species of honeysuckle sprout earlier and keep their leaves longer, which shades out other plants. The best method of control is early detection and eradication.

  • INHS and IDNR survey mussels in the Kishwaukee River

    The Kishwaukee River basin in northern Illinois remains one of the most mussel-rich resources in the state. In 2012, the INHS Urban Biotic Assessment Program began studying the fishes, reptiles, amphibians, and mollusks of the Kishwaukee River along the Illinois Tollway I-90 overpass. In 2015 UBAP began a longterm monitoring program of the mussel population at the site. Each August, a team of researchers from INHS, IDNR, and local land management agencies descends on the same location and intensively samples the mussels in the area over the course of a week.
