  • 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.

  • 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.

  • Illinois’ mild winter might benefit insect pests this spring

    Above normal air temperatures this winter kept Illinois average soil temperatures higher than usual.

  • Mild winter leads to butterfly innundation

    Environmental Almanac writer Rob Kanter consulted retired INHS Entomologist Mike Jeffords to find out why central Illinois has been inundated with red admiral butterflies. According to Jeffords, the red admirals we see in spring are migrants that overwintered to the south and the few that survived the winter here. This year the mild winter allowed greater survival and the subsequent swarms of red admirals. Jeffords, along with Susan Post (another retired INHS Entomologist) have found that other butterflies are active and numerous earlier than usual this spring. They reported seeing 22 species of Illinois butterflies before April, which is twice their usual number.
