New research from the BirdCast team highlights risks of exposure to artificial light at night for migrating birds. We ranked metropolitan areas where birds are at the greatest risk of becoming attracted to and disoriented by lights.
With the vernal equinox approaching, Team BirdCast welcomes back our forecast and live migration maps for the spring 2019 season!
Hurricane Michael strengthened rapidly into a major hurricane on Tuesday, and as with previous storms on which BirdCast reported, it may have dramatic impacts on local and transient bird communities and their habitats when it comes ashore and passes through the Southeastern US. Live sightings will appear on the current observations map as they are entered into eBird, but as always, for those in the path of this storm, safety first!
Real-time sightings from your eBird checklists will appear in this post’s map, providing a unique opportunity to help us understand how these storms transport birds and how birds respond to extreme disturbances in their annual cycles.
Hurricanes and their impacts, in particular in depositing seabirds far afield from their normal haunts, represent unique opportunities to understand how animals behave in and respond to serious disturbances. Hurricane Florence is no exception.
Thanks for all the memories! BirdCast automated forecast and live migration maps for Spring 2018 will be deactivated until 1 August 2018 – the last forecast map was published for the night of 31 May 2018, and the last live migration map will post on 15 June 2018. Please check back often for additional comments and posts on the spring 2018 season and the arrival of the farm migration maps on 1 August!
BirdCast predicts medium to high migration traffic aloft over an extensive areas of the central US from Mexico to Canada this weekend. Let’s take a look briefly at why we think this will happen, and what species will be on the move.
A strong cold front will move through the central US and bring precipitation and northerly winds to the Gulf of Mexico region. These factors are typically associated with coastal fallouts in many different habitats. Saturday and Sunday will be the primary fallout potential in the western Gulf region, whereas Sunday and Monday will be that potential in the east Gulf region.
In this short post we highlight tonight’s migration forecast in the West. Conditions are favorable for movements from the Desert Southwest north and west along the Pacific Coast into Washington state.

BirdCast tracks migration from many angles, including with interactive maps that can give us a bird’s-eye view of migration in progress. Check out arrivals of waves of Purple Martins.
With regular arrivals of spring migrants occurring daily, or nearly so, throughout the US, Team BirdCast returns with species on the move spotlights. This week, we highlight some on-time, early and late arrivals in the BirdCast West region.
Light, inbound trans-Gulf migration over Texas and Louisiana was visible in the Live Migration Map.
Team BirdCast highlights some relationships between migration and weather that could explain why our migration models predict migration in certain areas and not in others. Let’s take a quick look at the migration forecast for the night of 28-29 March 2018.
For our inaugural automated migration forecast and live migration map analysis post, let’s take a quick look to see how the maps compare!
BirdCast has been working toward automatically predicting and analyzing bird migration across the continental US, and we now unveil automated forecast maps and live migration maps. Welcome to the future of migration monitoring, please explore the new visuals and tune in frequently for discussion about movements!
With an unusual period of cold and snowy weather in western Europe, trans Atlantic movements of species like Northern Lapwing are possible. In keeping with previous discussions we have posted about this topic, BirdCast briefly discusses the potential for European vagrants to arrive in North America.
Continental Summary Local light to moderate flights were scattered across the West and feature numerous waterfowl in this late season period, while the pulses of moderate flights in the Great Plains and Southeast featured many species of waterfowl, Turkey Vulture, Bonaparte’s Gull, Eastern Bluebird, Golden-crowned Kinglet, Cedar Waxwing, and Dark-eyed Junco. Need a review of […]
Continental Summary Primarily unfavorable migration conditions in the West, coupled with the late date in the fall migration season, will allow for only local light movements featuring Northern Pintail, Green-winged Teal, Redhead, Pied-billed Grebe, Eared Grebe, Sandhill Crane, Say’s Phoebe, Varied Thrush, and American Pipit, while several pulses of energy moving through the East will […]
Continental Summary Local light and moderate flights were the norm in the West featuring Common and Barrow’s Goldeneyes, Trumpeter Swan, Bonaparte’s Gull, Snowy Owl, American Kestrel, and Horned Lark, while moderate and heavy flights occurred in numerous areas of the East featuring Canvasback, Common Goldeneye, Hooded, Red-breasted and Common Mergansers, Tundra Swan, Bonaparte’s Gull, Snow […]
