We will step through last week’s BirdCast forecast to see how it did with predicting the bird movements and species arrivals. The overall pattern has been of continued decent conditions for movement through the mid-continent, but northerly winds and cooler temperatures have…

After an amazingly early start to spring migration across much of the eastern two-thirds of North America, we expect migration to return to a more typical schedule this week. Arrival dates should be only slightly ahead of average through the…

Last week’s BirdCast forecast made a couple predictions about fallouts that we focus on this week. These include a widespread waterfowl fallout in the Northeast, which we discuss in some depth to help eBirders prepare for similar events in the future. Along…

Conditions across much of the West look favorable for light migration to occur during the course of the forecast period, particularly toward the end of the week. The distinct exception is the Pacific Northwest, which is again forecast to receive…

Last week’s BirdCast forecast predicted a slower week of migration, as weather in the East and Midwest turned cooler with northerly and westerly flow that would be less conducive to migration. Despite a record-early spring for many species to date, we predicted…

We expect the pace of record-early spring arrivals from throughout the eastern two-thirds of the country to slow significantly this week. While a few birds may continue to push north, don’t expect the massive movements of birds from the last…

Check out last week’s forecast, then read on to see how we did!

Last week’s BirdCast predicted another week of widespread migration and record early arrivals across the continent. The unsettled weather predicted to reach the mid-continent in mid-week prompted a…

A strong frontal boundary is currently moving east toward the Mississippi valley, having passed over the Texas coast and portions of Louisiana. This boundary is spawning strong storms and areas of precipitation (some of which is intense). Its passage coincided…

Expect another week of record early arrivals and large numbers of migrants across much of the continent. Mild conditions will dominate away from the far west where unsettled weather will continue. A large high pressure system will once again become…

Since the first units were placed along the Gulf Coast in the 1950s, ornithologists and birders have become increasingly aware of the power of using radar as a tool for understanding bird migration. In addition to detecting and depicting meteorological…

Refresh your memory with last week’s BirdCast, then read on to see how we did.

There was light migration in the mid-continent over the weekend, but building high pressure caused some very large nights of migration by mid-week on 13-14 March…

Expect a progression of good migration conditions very similar to last week’s. Conditions for bird migration will be favorable east of the Rockies and on the Great Plains over the weekend. By Monday and Tuesday these conditions make for good…
