One of the things that I hope the Google IL Birders' Map to be used for is ad-hoc area guides that show locations that may be known among birders who frequent the area, but to others remain a mystery.
Here's an example of the Palos area showing many, but not all (yet) of the birding areas. I hope to have these placemarks include what kinds of birds (particularly nesting species) may be found at each location.
And, please note that these embedded maps are fully-functional: you can click, pan, zoom etc. right in this window.View Larger Map
