News: Migration

April's Super Pink Moon will be visible after sunset and reach peak illumination at 11:33 P.M. EDT on 26 April 2021. For those wishing to see birds migrating at night, if the sky is clear, point a telescope or strong pair of binoculars toward the moon, particularly if you are in a location where the BirdCast model predicts medium to high intensity migration.  Read more...

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.  Read more...

The spring window for peak bird migration in Texas has arrived, so it's time to get outside and experience the coming spectacle! Just doing one simple thing will help protect these migrating birds: turn off all non-essential lights between 11pm and 6am every night to go Lights Out and reduce collision risk!  Read more...

Continuing frontal boundaries and associated unstable weather conditions in the Gulf of Mexico are going to make for some interesting migration patterns in the coming week.  Read more...

In the early morning hours of 9 April 2021, La Soufrière in St Vincent erupted and has continued to do so in dramatic and disastrous fashion in the days since the first explosion. The ash plume from these eruptions now spans a wide swath of the globe from the Caribbean to the western Mediterranean. Birds migrating through this plume may experience hazardous conditions, so observers in areas where concentrations of sulfur dioxide and other volcanic emissions are high should monitor birds' behaviors and physical conditions for potential signs of impacts.  Read more...

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.  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...

Easterly winds are blowing in the North Atlantic, and they may bring some surprise visitors to northeastern North America.  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...

Above average temperatures are coming to the eastern half of the US next week, and with these warming temperatures will come early season movements of birds. But for the western US, no such luck arrives. Keep a close eye on forecasts, ours included, to see what happens!  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...

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...

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...

BirdCast is thrilled to announce a public service announcement from former First Lady Laura Bush and a proclamation from Dallas Mayor Eric Johnson about the Lights Out Texas initiative to protect nocturnally migrating birds from the hazards of light pollution!  Read more...

More than half a billion birds will take flight tonight across the contiguous US tonight! The BirdCast model is predicting intense migration in many areas of the central and southeastern US in the wake of a passing cold front.  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...

Enormous, and growing, numbers of dead birds discovered in the southern Rockies over the past few weeks have alarmed scientists, conservationists, and advocates alike. The massive mortality events may be a result of intense fires in the western US and the smoke that they have produced.  Read more...

Yes, you read the title right— WHITE-breasted Nuthatches! Long overlooked as a humble resident of forests and feeders across North America, the *other* migrating nuthatch is finally getting deserved recognition for its irruptive travels.  Read more...
