This was an exciting week in spring migration as things really began to ramp up on a continental scale. The West saw significant movement throughout the region with a consistent flow of birds from the south, and some of the…

Areas of the western US lacking precipitation should experience widespread light to moderate migration early in the forecast period, but an increasing threat of precipitation later in the week may shut down movements in many places. The Great Plains begin…

This week saw widespread arrivals of a diversity of species in many areas–far too many to mention in full. In general, most Neotropical migrants have now reached the southern U.S. A few very late species such as Willow Flycatcher, Yellow-bellied…

Expect the best migration so far this year for at least portions of this week throughout North America. Many areas of the country will see fallout potential this week for passerines and waterbirds. The Desert Southwest and scattered areas of…

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…
