Southerly winds will make for pleasant but perhaps uneventful birding through Saturday, but rain arrives by Saturday night. No new major movements of birds will occur in the area until Sunday night. Migrants that arrived in the heavy movement of…

High pressure over the eastern Great Lakes creates favorable conditions for moderate to heavy movements on Friday night. Clear skies and cooler temperatures should bring another large wave of later fall migrants, including a diversity of sparrows, kinglets, increasing numbers…

For more than 50 years US radar aeroecology has largely been restricted to the lower 48 states — until now. Just out in the Proceedings of the Royal Society B, the BirdCast team publishes the first weather surveillance radar studies of Alaskan bird migration.

New approaches bridge gap between radar monitoring and species identification, advancing conservation efforts for birds during migration

The BirdCast team has unveiled a new feature on our maps! Forecast and live migration maps now indicate the total number of birds in flight above the contiguous United States.

Nana is approaching the coast of Central America, bringing with it the potential for tropical seabirds and downed overland migrants.

An evolving frontal boundary will make for some interesting conditions along the Atlantic Seaboard to transport birds farther afield than they might typically travel in the coming 72 hours.

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.

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.

19-22 April 2019 saw some spectacularly intense weather in the eastern US, with some obvious after effects in terms of migrating birds’ distributions. Read on for a brief description of events that presumably carried nocturnally migrating songbirds farther afield that they intended to travel.

The spring of 2021 offered many migration highlights, and here we showcase the top 5 mega-flights of this soon-to-be-in-the-books season.

Did Team BirdCast say spring 2017 and it’s only February? Are we incorrect in saying this on two conflicting fronts, first because of the record winter warmth in many parts of the US that already seems like spring (or summer!) and second because of the date on the calendar? Well, we may be incorrect because of the date on the calendar, but birds have been on the move for many weeks now. And the warm temperatures in many areas of the country have no doubt played a large role in some of the magnitude of these movements. Here’s just a sample of what’s on the move in the last week, to whet your appetite for our upcoming weekly migration forecast and analysis features.
