  • Cool, Wet Weather Slows Northern and Central Illinois Planting

    May 3, 2007 8:15 pm

    "Combined with cooler temperatures, wet April conditions led to widespread corn planting delays in the northern two-thirds of the state, where precipitation averaged 4.05 inches (0.46 inches above normal) and up to 5–7 inches at some locations. April temperatures averaged 49.5°F statewide (2.7°F below normal), and statewide precipitation was 3.75 inches (just 0.05 inches below normal), based on preliminary data. Southern Illinois was drier, averaging 3.38 inches (0.74 inches below normal), and planting there is further along," says State Climatologist Jim Angel of the Illinois State Water Survey (http://www.sws.uiuc.edu), a division of the Illinois Department of Natural Resources.

  • Cornboy vs. the Billion-Dollar Bug

    Feb 21, 2017 3:45 pm

    There is, despite the name, nothing urban about Piper City, Ill. It is a farm town with a skyline of grain elevators, a tidy grid of pitch-roofed houses and, a few blocks beyond, endless fields: corn, soybean, corn, soybean, corn, corn, corn, perfectly level, perfectly square, no trees, no cows, no hedgerows, no bare land. In late August of 2013, a man named Joseph Spencer followed a corn-flanked county road northwest from Piper City until his GPS advised him to leave the road altogether and turn onto a gravel track. Spencer, an entomologist who studies farm insects, was looking for a farmer named Scott Wyllie.

    Cowbird chicks do best with two warbler nest mates – not four, not zero, study finds

    Sep 15, 2022 10:15 am

    A new study seeks to understand the strategies cowbird chicks use to survive in prothonotary warbler nests when they hatch with different numbers of warbler nestlings. The study reveals that a cowbird chick does better with two than with four or zero warbler nest mates. 

  • Cowbirds aren't just deadbeat parents

    Sep 10, 2015 8:00 am

    A new study from INHS graduate student Matthew Louder, and INHS Ornithologists Wendy Schelsky, Jeff Hoover, and Amber Albores found that female cowbirds monitor nest success of their offspring and will lay their eggs in the most successful host nests. This, combined with previous work by Jeff Hoover and colleagues, shows that female cowbirds aren't just abandoning their eggs in a host nest. Nests that fledged cowbirds were much more likely to be parasitized by cowbirds again than those that failed to fledge cowbirds.

  • Crows are back, but West Nile Virus here to stay

    Dec 13, 2011 11:00 am

    During the years following the discovery of West Nile Virus in Illinois, Crow populations dropped from 300,000 to 110,000 birds. According to INHS Ornithologist Mike Ward, crows were highly susceptible to West Nile Virus, possibly because of their specialized immune systems and social lifestyle.  The cause of the rebound is not fully understood, but Ward stated that antibodies to fight off the virus have been discovered recently. Wet conditions during the summer may have also decresed breeding of the mosquito species that carries West Nile Virus.

  • Culling maintains low prevalence of Chronic Wasting Disease in deer populations

    Oct 21, 2013 8:00 am

    INHS Wildlife Epidemiologist Nohra Mateus-Pinilla and postdoctoral researchers Mary Beth Manjerovic and Michelle Green conducted research on the effectiveness of culling deer to prevent the spread of Chronic Wasting Disease (CWD).

  • Danville, crow capital of the world

    Feb 1, 2013 8:00 am

    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.

  • Deer ticks more adaptable than previously known

    Jun 28, 2011 2:00 pm

    Deer ticks, the host species for Lyme disease, feed on a variety of animals, with white footed mice (a forest species) as the main reservoir for the disease causing bacteria. INHS Wildlife Epidemiologist Nohra Mateus-Pinilla, graduate student Jennifer Rydzewski and Richard Warner (NRES) found that the highest prevalence of infection at Allerton Park was from the prairie, with prairie voles as the reservoir. "What's exciting about the new findings is that we are dealing with potentially new mechanisms of disease transmission that we just have not explored and perhaps we do not understand," Mateus-Pinilla said. "We need to think outside of what we already know about Lyme disease transmission."

  • Digitization of biological collections will make fragile specimens more accessible for study

    Jan 30, 2012 8:00 am

    The biological collections of the Illinois Natural History Survey are among the largest in the nation, with nearly 10 million specimens collected over the past 150 years. These collections document our natural heritage and can be studied to understand variations within and between species, changes over time, and countless other topics. Many of the specimens are fragile and must be stored and handled with extreme care. As part of a $10 million grant from the National Science Foundation, researchers at INHS are working with several other institutions to digitize collections, taking high resolution images from a variety of angles. Scientists from around the world will be able to see the images of the specimens and physically handle only the ones that they need for closer examination. For more information on the invertebrate side of the project, check out the InvertNet website.
