Continental Summary
A general quiet late season period in the West will see scattered light flights in the middle of the work week that feature Northern Shoveler, Northern Pintail, Tundra Swan, Northern Harrier, Sandhill Crane, Mew Gull, and Say’s Phoebe, while two strong frontal passages will bring light to moderate late season flights of Canada Goose, Tundra Swan, Bufflehead, Long-tailed Duck, Red-throated Loon, American Pipit, White-throated Sparrow, and Dark-eyed Junco to the East.
Wondering what species are migrating through right now? Check out our {LINK TO ANALYSIS} for the past 7 days.
Arrows show wind speed and direction (arrow points in the direction to which wind is blowing) 100 m above ground level. Areas with southerly winds are colored red; northerly winds colored blue. Accumulated precipitation (in 6 hour intervals) is green, outlined by white. Broadly speaking, areas of the map in blue will experience conditions that are favorable for migration, and areas where blue and green (and red and blue) intersect and overlap may experience migrant concentrations and fallouts as migrants interact with precipitation.
We use data collected by eBird users help make more accurate forecasts. If you enjoy the predictions contained in these posts, please consider submitting your own bird sightings to eBird to even further improve the content. Every observation counts, whether it be a single bird at a feeder in your backyard, or an entire day spent in a national park. To get started with eBird, head on over to the site !
Additionally, please note that photographs and other digital media showing birds come from the Macaulay Library , which receives credit along with the photographer/observer in the media caption as part of a new initiative that allows public contribution, access and use of natural history media .

Quick Links to Regions
Upper Midwest and Northeast
An intense storm system moving through the Great Lakes and into the northeastern US will bring moderate flights with its passing, locally heavy in some areas. This system may also bring some exciting vagrants to the region, and birders should be watchful (for example, systems like this often deposit Cave Swallows and sometimes bring Franklin’s Gulls). In addition, birders should watch for areas with snow cover to see significant diurnal movements of larks, pipits, sparrows, and buntings. The favorable conditions for migration will continue in the northeastern US through Wednesday, while most of the remainder of the region sees favorable migration conditions deteriorate. However, the next frontal boundary pushes through the region on Thanksgiving, yielding another pulse of light to moderate late season migration.

Gulf Coast and Southeast
A frontal passage brings favorable conditions for widespread moderate movements for the weekend, becoming increasingly restricted to the southeastern US and Florida by Monday. The next frontal passage arrives, bringing a pulse of light to moderate, and even locally heavy, late season movements first to areas west of the Mississippi River on Wednesday then more widespread and to the east on Thursday.

Moderate to locally heavy movements kick off the weekend after the passage of a strong frontal system and winter storm. The scene quiets significantly until Wednesday, when the arrival of the next storm system is expected. As this system passes, light to moderate movements will follow on Wednesday and Thursday.
