Occurence.


Want to be mesmerized by an expanding orange glow while being reminded of how little and flightless you are? Then ebird.org's bird occurrence maps, which track the movement of 57 different bird species across the US using lava lamp-esque visuals, are perfect for you. 

The maps, a collaboration between the Cornell Lab of Ornithology and the National Audubon Society, are predictions for how likely you are to find any given bird on a one kilometer walk at 7 a.m. in the morning. They are built from a massive collection of data–280 million observations from around the world submitted by thousands of birdwatchers–and use a method known as the Spatio-Temporal Exploratory Model (STEM).
