Great Blue Herons

On March 15, SETF along with representatives from Chicago Audubon, Chicago Department of the Environment, The Chicago Legal Clinic,  two Northwestern students, and a reporter gathered on a mission to scout for nesting Blue Herons near Whitford Pond.  Blue Herons are large waterfowl that build their nests high atop trees next to ponds that serve as sources of food for the birds.

We were hiking the property owned by the Metropolitan Water Reclaimation Department, the site that the Chicago Police Department is proposing to build an outdoor firing range on and the only site in Chicago known for nesting Blue Herons.  The property is isolated, being surrounded by landfills on three sides.   It was last used as a staging area for the deep tunnel project and still contains limestone spoils that had not all been removed.  We walked atop those spoils toward the pond and where the spoils ended, the marshy terrain began.  As we trumped through the ankle deep water toward the huge nests that were easily visible in the bare trees, the nervous birds took flight.  We continued hiking toward the pond curious to get a closer look, noting the many deer tracks along the way.

We had to scale a berm in oder to get a view of the Whitford Pond. This time of the year it’s a rippling pool of water surrounded by thinned out Phragmities.    With mission accomplished and not wanting to disturb the birds any more, we headed back to the SETF office to warm up with a hot cup of coffee.
