Ornithologists and bird watchers rejoice. After a dozen years, The Cornell Lab of Ornithology’s Macaulay Library has fully digitized its nearly 150,000 audio recordings (a total running time of 7,513 hours), representing close to 9,000 different species, such as the very unsettling-sounding Barred Owl (above). While the collection also includes the sounds of whales, elephants, frogs, primates, and other animals, the primary emphasis here is on birds (it is a Lab of Ornithology, after all), and there is an incredible range of calls.

Pulling millions of observations from the eBird citizen-science database, scientists from the Cornell Lab of Ornithology have mapped out the migration of 118 bird species in the Western Hemisphere. The resulting map represents the average location over the course of a year for each of these species of birds as they make their annual migrations. A similar map with a numbered key for those wanting to know which species are which can be accessed here.

In Ithaca, New York, a virtual machine in a laboratory at the Cornell Lab of Ornithology sits in the night, humming. The machine’s name is Bubo, after the genus for horned owls. About every five minutes, Bubo grabs an image from Northeast weather radar stations, and feeds it through a pipeline of artificial-intelligence algorithms. What does this radar image show me? Bubo asks. Is it rain? Are these insects? Could it be pollen? Bubo doesn’t care about those things; all it wants to see are birds in flight. To find them, Bubo analyzes the velocity and direction of targets seen by the radar station. Bubo knows birds have a velocity different from wind and insects, and filters those out. Now Bubo sees only birds. But how dense are they? How fast are they going? How high in the sky are they (...)
