When, where, and how far will birds migrate? Our migration forecasts will answer these questions for the first time.
Bird migration forecasts powered by 23 years of radar observations and the most recent North American Mesoscale weather forecast. Migration forecasts show predicted nocturnal migration 3 hours after local sunset and are updated every 6 hours. Learn more
A study published today in the journal Science reveals that the volume of spring migration, as measured by the NEXRAD radar network in the night skies, has dropped by 14 percent in the past decade. The paper further compiles bird survey data collected on the ground, indicating that bird populations in the United States and Canada have declined by 29 percent since 1970, representing a loss of almost 3 billion birds.
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.
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.
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.
