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).
