Canada goose
Branta canadensis
Description You know what a goose looks like.
Habitat Any park or forest preserve, along the lakefront and in concrete parking-lot islands. They’re everywhere.
Notes Please don’t feed the geese—especially that loaf of bread. “It can lead to a number of different illnesses,” says Mike Redmer of the Chicago Field Office of the U.S. Fish and Wildlife Service. Bread is like goose junkfood, and can lead to deformed wings in baby geese, for instance. And be aware, geese defend their nests. Walk within a five-foot perimeter, and you run the risk of getting goosed (or nipped).
I LOVE POSSUMS!!!!
The nests you are seeing are not in Rosemont, they are off of 90 in Busse Woods near Arlington Heights, and they are mostly Great Blue Herons along with a few other species.
Bats aren't rodents.
This Place is a Zoo -- Big Brown Bat...Did your writer really think that bats are rodents? They are mammals and are closer related to humans genetically than they are to mice. I could see if there was a ha ha in the little write-up after it says flying rodents, but looks like he/she was serious. I think if Larry Heaney, who is quoted in the article, ever sees this he'll be pretty ashamed and upset to be associated with such a misconception.
I have often noticed a rookery of nests close to Rosemount, IL. Does anyone know if these are eagles or a type of heron?
