During the week of April 19-25, several weather events set up excellent conditions for observing visible migration, mostly of wood-warblers, including this Worm-eating Warbler, migrating along Florida’s east coast. Our colleague Jacob Drucker reports on his observations on the ground!  Read more...

On Saturday 10 April, a frontal boundary is forecast to move into the Gulf of Mexico region. Beginning midday Saturday, birds may begin concentrating in coastal habitats, particularly in the Upper Texas and southwestern Louisiana coasts; but events may be quite complex, because forecasts suggest that the front will stall.  Read more...

Winter Storm Xylia is forecast to bring a blast of late winter to the Central Rockies and northern Great Plains this weekend and early next week. Birds will certainly respond to this storm, especially those of more open terrestrial habitats, by seeking more favorable locations free of snow if possible.  Read more...

As the calendar page turns to March, the BirdCast team opens the spring 2021 migration forecasting season with the return of forecast and live migration maps! Birds are already on the move and have been for many weeks, but number have been increasing, particularly in the southeastern US last night. Read on to check on what species might be on the move in your part of the country.  Read more...

Welcome to 2021! Team BirdCast has a number of projects underway for this year. And although we are still a good 4-6 weeks from the first significant movements of mid to late winter migrants moving in the US, keen observers should be aware of several patterns to watch now.  Read more...

Migration
By Matthew A. Young and Tim Spahr, Finch Research Network Guest Authors Dec 18, 2020

During Fall 2020 a “superflight of finches” occurred in the eastern US, featuring the biggest Evening Grosbeak migration in more than 20 years, redpolls undergoing their largest movement in perhaps a decade, and Pine Siskins irrupting in their best numbers since 2008. These ‘Finch Superflights’, which are defined as southern flights of all eight eastern irruptive finches, are rare, and this year, conditions have aligned and all species have moved in numbers, including the rarest of irruptives, the Pine Grosbeak.  Read more...

Numerous storm-driven birds have likely appeared in peninsular Florida as the meandering Tropical Storm Eta churns in the Gulf of Mexico. With the forecast for the storm to make landfall and move quickly off into the Atlantic Ocean in the coming 24 hours, safe and careful observers may find a range of Gulf of Mexico seabirds and some displaced waterbirds.  Read more...

Hurricane Zeta is powering toward the Louisiana coast, predicted to make landfall on Wednesday afternoon. This storm will certainly entrain Gulf of Mexico seabirds, as well as displacing some nearer shore species inland and dropping overland migrants. Given the storm's arrival time, predicted track and speed, birders from the Louisiana coast to Cape May, NJ should keep safe, socially distanced, and watchful eyes on all bodies of water and your favorite birding patches.  Read more...

Easterly flow in the North Atlantic has the potential to bring European species into northeastern North America in the coming days. Marginal to favorable conditions for such displacement are predicted for the coming days, so birders should watch their favorite patches closely.  Read more...

Hurricane Delta is a powerful storm predicted to make landfall late on Friday on the Louisiana coast. Gulf of Mexico seabirds, as well as some nearer shore species and overland migrants, will be associated with the arrival and passage of the storm as it moves inland to the north and east.  Read more...

The BirdCast model is predicting high intensity migration this evening, with more than half a billion birds on the move! And there will be additional, similarly large flights, in the coming nights! This will likely represent one of the largest series of migration nights of the year in the contiguous US.  Read more...

At this point you have heard the stories for the west about bird mortality, but perhaps you have not heard the stories about species on the move out of the mountains. BirdCast will feature evolving stories about eruptions from higher elevations, and this week we highlight Mountain Chickadee.  Read more...
