Monitoring at the National 9/11 Memorial & Museum Tribute in Light, 2019

Members of the BirdCast team will be at the Tribute in Light with New York City Audubon volunteers to monitor bird appearing in the intense beams of light this evening and collect additional data to study the effects of these intense lights on bird migration.

Interactive Map: the passage of Hurricane Dorian

Hurricanes and their impacts, in particular in depositing seabirds far afield from their normal haunts, represent unique opportunities to understand how animals behave in and respond to serious disturbances. Check out live sightings of species that may by associated with the passage of Dorian this week.

Migration alert: Nocturnal migration around Hurricane Dorian

BirdCast tracks with great interest the movements of hurricanes and the pelagic species that they often entrain and displace on shore and at times far inland. The team is also interested in bird migration around hurricanes, and with the arrival and passage of Hurricane Dorian off the coast of Florida, Georgia, and the Carolinas, we can see how some birds handle the circulation of an intense cyclonic storm.

BirdCast’s Fall 2019 Campaign Begins

Welcome to fall migration season 2019 for BirdCast! Our 3-day forecast maps have returned, and our migration maps are live, so you can check predictions for and monitor nightly migration intensity through the fall season. Please visit us often!

MistNet: Measuring historical bird migration in the US using archived weather radar data and convolutional neural networks

Welcome MistNet, a deep convolutional neural network to discriminate precipitation from biology in radar scans! MistNet is a tool that can enable large‐scale, long‐term, and reproducible measurements of whole migration systems, a hallmark of developments by our collaborators at University of Massachusetts and the BirdCast team. Read on to find out more about today's paper published describing this exciting new tool.
