Team BirdCast is highlighting an area where fallouts and concentrations may occur over the course of the day. An areas of significant storms and precipitation is moving slowly north and east over the western Gulf Coast, impacting Louisiana and nearshore off the immediate coast.

Conditions are mostly marginal for scattered light to moderate flights of Long-billed Dowitcher, Wilson’s Phalarope, Western Wood-Pewee, Swainson’s Thrush, Yellow Warbler, Western Tanager, and Bullock’s Oriole after a strong frontal passage in the West, while the first half of the period in the East see many areas with favorable conditions for moderate to very heavy flights featuring Short-billed Dowitcher, Black Tern, Common Nighthawk, Willow Flycatcher, Least Flycatcher, American Redstart, and Wilson’s Warbler. Conditions for trans-Gulf migration will be generally favorable during the period, with the potential for late weekend and early work week fallouts and concentrations in the Gulf Coast states as frontal passages with precipitation are forecast.

Team BirdCast has been watching the trans- and circum-Gulf movements unfold in the last days. Today’s movement is an exciting one, featuring the arrival of large numbers of migrants and another frontal boundary.

Last week, Team BirdCast highlighted at potentially complex scenario for inbound Neotropical migrants in the Gulf of Mexico. Let’s get a brief update to see what happened.

We’ve created a new tool to update us as species advance through their arrivals in each region, using data from eBird. We assign each species to four possible categories: Not Yet Arrived, Arrival Beginning, Approaching Peak, or Peaking. Then, we…

This week, Team BirdCast highlights a friend in the field. Today, it is Dr. Emily Cohen, a research associate at the Smithsonian Conservation Biology Institute.

The West will see light to moderate flights, particularly in the Desert Southwest late in the weekend and late in the work week, featuring Spotted Sandpiper, Long-billed Dowitcher, Swainson’s Thrush, Townsend’s Warbler, MacGillivray’s Warbler, Black-headed Grosbeak, and Western Tanager, while a pulse of highly favorable migration period late in the period in the East will bring moderate to very heavy flights featuring Red-headed Woodpecker, Acadian Flycatcher, Least Flycatcher, Swainson’s Thrush, Chestnut-sided Warbler, Bay-breasted Warbler, Northern Parula, and Mourning Warbler. Early period brings a dynamic and complex atmosphere will potential for Gulf Coast concentrations, where late period brings a major incursion of Neotropical migrants across and around the Gulf of Mexico, as favorable flight conditions arrive in Mexico and northern Central America at the peak of the season.

Moderate movements featuring Semipalmated Plover, Caspian Tern, Olive-sided Flycatcher, Warbling Vireo, Swainson’s Thrush, Nashville Warbler, and Western Tanager were the norm for California and the Desert Southwest, while moderate to locally heavy flights graced portions of the East and featured Spotted Sandpiper, Great Crested Flycatcher, Red-eyed Vireo, Wood Thrush, Blackpoll Warbler, Baltimore Oriole, and Dickcissel.

Here comes the BirdCast World Edition again! Here, we highlight a species with an extensive global distribution and focus on populations that winter in and migrate through southeast Asia: Barn Swallow!

Team BirdCast is including a World Edition to bring a more diverse array of forecasts and analyses for this season. In this week’s post, we briefly feature four species: Common Cuckoo, Barn Swallow, Eurasian Blackcap, and European Robin.

Scattered favorable conditions primary in the middle of the forecast period will see light to moderate flights of Green Heron, Western Sandpiper, Red-necked Phalarope, Olive-sided Flycatcher, Hammond’s Flycatcher, Warbling Vireo, and Townsend’s Warbler for the West, while widespread favorable migration bring moderate to heavy flights in many areas of the East and will feature Sora, Least Sandpiper, Semipalmated Sandpiper, Common Nighthawk, Blue-headed Vireo, Kentucky Warbler, Summer Tanager, and Painted Bunting. Continued unfavorable conditions in many areas of northern Central America will slow the typical seasonal pulses of trans-Gulf migration.
