This week the Gulf Coast of the US will experience landfall of two tropical systems, Laura and Marco. This dangerous twin bill will come with flooding, storm surge, heavy rains, and wind in many areas of the western Gulf of Mexico and lower Mississippi River valley. BirdCast is tracking the arrival of the two storms, and you can monitor with us on two maps tracking bird observations as they occur with landfall.  Read more...

Sooty Tern is often the bird of tropical weather systems once ashore (or very close to shore). Numerous records of far-flung individuals pepper the archives of such weather systems, and Hurricane/Tropical Storm Isaias was no exception.  Read more...

Hurricane Isaias is forecast to make landfall in the US on the Carolina coast after grazing the Florida Peninsula and passing directly over the Bahamas and nearby islands. This storm will likely produce hazardous conditions where it passes, including damaging winds, dangerous storm surges, and torrential rains with flooding, and it will bring seabirds and other entrained and displaced species ashore far afield from their typical locations. Check out our live sightings map at the end of the post; and follow updates as we make them.  Read more...

A tropical system is building in the Gulf of Mexico, forecast to intensify in the coming days and then move ashore in central or southern Texas. Whether this system intensifies to hurricane strength or continues as a tropical storm or depression, it is likely to bring an array of seabirds ashore in southern and central Texas and possibly northern Mexico.  Read more...

Tropical Storm Fay is a fast moving system that is forecast to travel a similar path to Hurricane Irene at a similar time as Tropical Storm Bertha. What will this system hold for those that can observe safely in the DelMarVa, coastal New Jersey and Long Island, Hudson River Valley, Lake Champlain, and St. Lawrence RIver Valley areas?  Read more...

We are nearing a seasonal window during which many records of Fork-tailed Flycatcher, a spectacular and elegant vagrant to the US from South America, have occurred. The BirdCast team thought you might like to know that conditions could be favorable for the arrival of this wandering species somewhere in the US ... maybe.  Read more...

23 May 2020 on the eastern shore of Virginia brought some migration magic to a small habitat patch for some lucky observers. Just over 200 migrants in a 10-acre patch. Our friend Ned Brinkley describes the action and puts it in proper perspective.  Read more...

A stationary front in the Carolinas, evolving into a cold front and moving offshore with some strong storms and southerly flow in advance of its movement, could make for some interesting birding along the immediate mid Atlantic and Long Island coasts.  Read more...

Although Tropical Storm Arthur is not predicted to make landfall, winds associated with the system's passage will impact the coastal US from the Carolinas through southern New England in the coming days. These winds, depending on location, may be sustained at 20-30 knots for several days, and could bring an array of typically pelagically distributed species ashore.  Read more...

17-19 May 2020 may bring an interesting shorebird event to the Pacific Coast of North America. An approaching strong storm system well timed to coincide with movements of spring shorebird migrants in the eastern Pacific could entrain and displace an array of unusual species.  Read more...
