Give thanks for turkey vultures

Post by Jen Berlinghof

Come late November, most of us have turkeys on the brain. But a different type of turkey is taking to the skies at this time of year on its annual migration south: the turkey vulture (Cathartes aura). You can spot them in the sky or on the ground in the Lake County Forest Preserves in northern Illinois.

Favorite photos from 2014

Post by Allison Frederick

The end of another year is drawing near. To celebrate the biological diversity protected within the Lake County Forest Preserves in northeastern Illinois, I’ve put together a collection of some favorite images from 2014. We have such an amazing support system of photographers who donate their time and images to communicate our cause. Their passion for wildlife and the outdoor spaces our organization preserves is evident in each image they share. I hope you enjoy them half as much as I enjoyed choosing this set! Each photograph was taken right here in Lake County, Illinois.

The slideshow will run on its own, but you can speed it up by clicking on the arrows. To see more amazing images from the forest preserves, or to share photos of your own adventures, join our group Flickr pool.

Thanks for following our blog. Knowing there are others who enjoy the beauty and complexity of our native landscapes is very satisfying. Have a great holiday season!

A snowy spark

Many years ago, while running along the Lake Michigan shoreline late on an evening in January, a feathered ghost appeared on top of a flag pole. It was the first time I had ever seen a snowy owl (Bubo scandiacus) and it stopped me in my tracks. This was the spark on that frozen night that lighted my fire of curiosity about birds. This winter, snowy owls have left their Arctic homes in record numbers, causing one of the largest irruptions (sudden increase) in northern Illinois in decades.

Although it seems natural to correlate the arrival of these boreal birds with the extremely cold, snowy winter northern Illinois is having, experts say the motivator is more likely linked to food. On their Arctic breeding grounds, snowy owls feast under 24-hour sunshine. Their food of choice is lemmings, small mammals with an extremely cyclical population. Bird expert Kenn Kaufman explains in a recent Audubon magazine article, that when the lemming population explodes, like it did last summer in northern Quebec, snowy owls have great breeding success, producing large broods of up to 11 chicks. As these chicks quickly grow into juvenile birds, the competition grows for the now dwindling numbers of lemmings. Thus, the young birds get nudged further and further away to find a meal, resulting in them moving to areas that mimic their treeless tundra home, such as the Lake Michigan shoreline. Continue reading
