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...

Despite scattered medium to high intensity movements in the past 7-10 days in the northeastern US, punctuating some otherwise abysmally and anomalously cool conditions, tonight will see a significant change. Medium to high intensity movements are predicted across a wide swath of the region, including in areas where fallouts and concentrations may occur as a result of birds interacting with rain.  Read more...

BirdCast reports on many aspects of bird migration, and sadly one scenario we encounter is mass mortality during migration. For example sometimes birds are downed when migrating over water, only to be found in the stomachs of tiger sharks; other times birds collide with myriad structures. In this case, we were alerted to a post, […]  Read more...

A line of intense storms approaching the western Gulf Coast will make for interesting and challenging conditions for inbound trans-Gulf migrants. The strength and the timing of frontal passage, as well as its projected extent over water, suggest potential for larger fallouts farther south and west along the coast, in addition to those fallouts that […]  Read more...
