I have checked this out and signed up for it as well. My first (and so far only) observation - 2 Carolina Wrens fussing on our front porch this morning. And I checked the interactive map and sure enough the green circle is there at the location of my home in Rutherford County, TN. I will be submitting future observations to My Ebird in the future and checking to see where others have observed certain species. Barry Jernigan Murfreesboro, Rutherford Co, TN
