Note Date Change to Fourth Tuesday of Month
Mark H.X. Glenshaw has closely observed and documented the lives of a mated pair of Great Horned Owls in Forest Park, a large urban park in St. Louis, since 2005. He will share the story of how he found these owls, the wide range of behaviors he has seen, and what he’s learned about the species in hours of observation.
Who doesn’t love watching a bird sing his heart out to attract a mate? David Enstrom, a retired ornithologist with the Illinois Natural History Survey, will describe the way birds produce songs and colors and how they are used in displays, how bird perception differs from human perception, and what this means to our understanding of bird behavior. He will also touch on how the study of birds affected the history of evolutionary science and share some spectacular examples of avian displays.
Whether identifying flora and fauna in the field with a click or using it to record your own non-bird observations, iNaturalist is an invaluable new tool for nature lovers. Local birder/restorationist Jeff Skrentny will explain how to use the app and tell some of the tales behind his 11,000+ iNaturalist entries representing over 2,600 species of bird, insect, mammal and plant life.
SPECIAL OFF-SITE PROGRAM – Registration Required
With several years of preserve restoration nearing completion, learn about Fort Sheridan’s history, architecture, notable residents and more, complete with artifacts from the museum’s archives. Then stay to tour the Lake County Forest Preserve District’s new museum at 1899 West Winchester Rd., Libertyville. $8 per person at the door. Register at email@example.com.
Warming temperatures, increasing precipitation and other climate changes are already impacting the flora and fauna of the upper Midwest. The Field Museum’s Doug Stotz will discuss how these shifts are changing the timing of bird migration and breeding, the wintering and breeding range of birds in the Chicago region, the environmental factors influenced by climate to which birds may be responding, and strategies for helping nature adapt to climate change.
Lake County is home to eight species of bat. Andrew Rutter, Lake County Forest Preserve District wildlife ecologist, will introduce us to each species, their unique life history characteristics and ecological roles, LCFPD’s efforts conserve habitat for bats and other wildlife, and the Citizen Science Acoustic Bat Monitoring Program that is documenting the diversity and distribution of bat species in Illinois.
Glenview’s Carol Freeman spent more than a decade photographing all 483 threatened and endangered species in Illinois, from plants to birds, insects and other animals, culminating this fall in the publication of a book called Endangered Beauty. She will share the inspiration behind the project as well as stories of how she captured some of her photos.
Sandhill Crane populations were dropping precipitously in Wisconsin 80 years ago, prompting naturalist Aldo Leopold to worry that they would soon disappear altogether. Today flocks of upwards of 10,000 birds converge on the Wisconsin River near the Aldo Leopold’s Shack each fall. That’s a large proportion of the cranes that now nest in Wisconsin. Stan Temple, retired University of Wisconsin-Madison professor, will review the birds’ remarkable recovery, describe their migratory behavior, and discuss some of the recent controversies, such as crane hunting, that have attended their new status as an abundant bird.Sand
