As the thermometer dipped to -8 degrees Fahrenheit this week, one thing was clear: the snow and cold are entrenched for a while longer. So are the stories of the animals, as told by the tracks etched in the frozen landscapes that sweep across the Lake County Forest Preserves. We may not see the animals themselves. However, each track, pile of scat, bit of hair clinging to a branch, hole in the snow and chewed acorn is an element of the tale from their winter excursions.
How do we decipher these stories? When trying to identify which animal made a particular track, it is important to look not only at the individual track but the overall pattern. Also, scan the surrounding habitat for clues.
Let’s see if you can figure out what happened in each of these nature vignettes:
Last week, many of us who work at the Lake County Fore
st Preserves had to say a sad goodbye. Our resident eastern screech-owl (Otus asio) passed away in the middle of the night. This male owl had spent the past seven years as an ambassador for the Lake County Forest Preserves, teaching thousands of people about the adaptations of raptors and owls. I have seen time and time again—from school children on education field trips to adults attending special events—a person’s eyes lock in and a look of amazement wash over them upon meeting this charismatic bird.
Sadly, his story is not uncommon. This particular bird was recovered in January 2004 as a juvenile. He was found by a concerned citizen in a driveway in Round Lake, Illinois with obvious head trauma and his left eye swollen and filled with blood. He was taken to Barnswallow, a raptor rehabilitation center in Wauconda, Illinois. It is suspected that this screech-owl was hit by a car, but he also had tiny sores on his talons and translucent, sheared tail feathers. These latter symptoms are signs of secondary viral infections caused by the West Nile Virus. After spending 16 months at the rehab facility, he was deemed unsuitable for release back into the wild due to the uncertainty of his eyesight in the injured eye. In the spring of 2005, he came to live in his very own mews (i.e. flight cage) near the farm area at Ryerson Woods. There he joined another resident bird, a red tailed-hawk (Buteo jamaicensis).
