Birding can be rewarding but, whether you're a novice or have years of experience out in the field, it can be tricky to get those identifications just right.
We often see this firsthand, with members of the public seeking us out for an identification or opting to open it up to everyone on the District's Will County Wildlife Facebook group.
For any birder, there are key features that can offer some clues, such as size, shape, plumage and the structure of a bird's bill. But distance, poor lighting and a number of other variables out in nature can make it difficult or nearly impossible to come to a clear conclusion.
For our quiz, we've eliminated those variables, so go ahead and put yourself to the test to see how well you know all of these feathered friends. It also could come in handy if you're participating in the "Big Day - Bird Hike Challenge," which runs through August 17.
