Migration Science: one in every four birds gone in the US and Canada

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. 

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.
