A frosty update from Nature Boardwalk at Lincoln Park Zoo—yesterday’s survey turned up these raccoon tracks on the ice. Things have slowed down for the season, but there’s still activity to spot out here!

If you’ve recently strolled around Nature Boardwalk at Lincoln Park Zoo, you may have noticed its icy disposition. Specifically, oddly configured, jagged chunks of ice positioned near plantings surrounding the South Pond. What’s up with that?

It has been more than two years since Urban Wildlife Institute biologists introduced painted turtles equipped with radio transmitters to the pond at Nature Boardwalk at Lincoln Park Zoo. Since then, we’ve been tracking the movements of these individuals as well as a few snapping turtles that we’ve gotten the opportunity to transmitter.

Have you ever seen a black squirrel around Chicago? This squirrel, photographed by one our motion-triggered cameras, is not a rare species but rather an eastern gray squirrel with melanism.

The introverted bottle gentian is all hue and no cry. This perennial, currently in brief bloom, displays richly violet, bottle-shaped flowers that never open. The corolla (petals) remains closed even when the flower is ready to receive pollinating insects. The burly bumblebee, consequently, is the plant’s primary pollinator, because it’s able to pry open the petals to get at the nectar and pollen. The petals usually feature five lobes, but they’re difficult to discern because of a taller, interconnecting fringe. Inside, the reproductive structures of the flower are fused together to form a central column. Multiple stems can emerge from the taproot of the plant, which is otherwise unbranched. The upper surfaces of its lance-shaped leaves are dark green and often shiny. Populations of bottle gentian plant are probably declining due to wetlands destruction.
