Field notes
The page groups sightings first by neighborhood, then lets visitors zoom toward individual reports; colors adjust to the currently visible area, while bright dots mark exact spots reported more than once. It provides Day, Week, 30 Days, and Year views alongside address lookup and ZIP filtering. The rankings cover 76 neighborhoods, with Lake View ahead of Portage Park and West Town in the displayed 30-day snapshot.
