To follow yesterday’s post, get out a look for landbirds!!!! Something extremely interesting is occurring in the wake of the epic passage of Sandy. Recent reports from Maryland to Maine of a bizarre mix of Neotropical migrants, including Connecticut Warbler…

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.

After a long and cold go of it in many parts of the eastern US in the past weeks, the prospect for warmer weather, even if ephemeral, is almost certain lighten many moods. So too might it provide a kickstart…

In March 2012 much of the eastern US experience anomalously warm temperatures in March that correlated with record early arrivals of migrants. This weekend, across some of the central US and much of the western US, anomalously warm temperatures are forecast. The image…

Some seriously anomalous displays of displacement, entrainment, diversion, and irruption, highlighted the birding landscape of 2012. Of particular note was the unprecedented invasion of Razorbills in the southeastern US and the Gulf of Mexico. BirdCast spent some time chronicling these events and begins a discussion of whether 2015 might see a similar occurrence.

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.

2014 may be a year to remember for linking bird movements to patterns of sea surface temperature (SST) anomalies. Many along the Atlantic and Gulf Coasts will certainly remember the winter of 2012-2013 for, among other reasons, the crazy Razorbill…

Spend your spooky Halloween evenings safely enjoying late season bird migration. For the intrepid with no aversion to long nights outside in cold temperatures, direct your optics to the face of the Micro Blue Moon to watch birds pass!

Doppler weather radar data—like those shown in the animation above and often featured in weather broadcasts—can tell us much more than how much rain will fall on your weekend cookout.

Here at BirdCast, we turn weather radar data into information on…

The GloBAM research consortium published a letter in Science with a call for European national meteorological agencies to provide biological and meteorological data from its radars.

This weekend’s change in temperature will harken the first big flocks of Brant, and numerous other species, arriving in the northeastern US.

In the early morning hours of 9 April 2021, La Soufrière in St Vincent erupted and has continued to do so in dramatic and disastrous fashion in the days since the first explosion. The ash plume from these eruptions now spans a wide swath of the globe from the Caribbean to the western Mediterranean. Birds migrating through this plume may experience hazardous conditions, so observers in areas where concentrations of sulfur dioxide and other volcanic emissions are high should monitor birds’ behaviors and physical conditions for potential signs of impacts.
