Urban Wildlife Nocturnality Shift

Interactive 3D city-block simulator: watch how mammals like foxes and raccoons shift their daily activity toward night as human disturbance rises, with live activity curves and a real temporal-overlap statistic.

A city block runs through a full day-night cycle while foxes, deer or raccoons forage in its parks and alleys alongside pedestrian and traffic activity. As you raise the human disturbance slider, the animals' activity distribution measurably shifts away from the hours people dominate and into the night — the same temporal-avoidance pattern documented in global camera-trap studies of urban and peri-urban mammals. Live 24-hour activity curves, a nocturnality index and a real kernel-density overlap statistic (Δ) track the shift numerically as it happens, alongside a rendered city where animal sightings visibly cluster into darker hours.

⚙ Under the hood

A 3D city block runs through a day-night cycle while foxes, deer or raccoons forage in its parks; raise the human disturbance slider and watch their 24-hour activity curve measurably shift toward night, tracked live with a nocturnality index and a kernel-density overlap statistic.
