The BirdCast team led a study published today that uses two decades of data to show that migration magnitude, light output, and wind conditions are important predictors of collisions at a high-profile building in Chicago. This research has global implications for conservation action campaigns aimed at eliminating an important cause of bird mortality: light pollution and resulting collisions with structures.  Read more...

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.  Read more...

Welcome to 2021! Team BirdCast has a number of projects underway for this year. And although we are still a good 4-6 weeks from the first significant movements of mid to late winter migrants moving in the US, keen observers should be aware of several patterns to watch now.  Read more...

Migration
By Matthew A. Young and Tim Spahr, Finch Research Network Guest Authors Dec 18, 2020

During Fall 2020 a “superflight of finches” occurred in the eastern US, featuring the biggest Evening Grosbeak migration in more than 20 years, redpolls undergoing their largest movement in perhaps a decade, and Pine Siskins irrupting in their best numbers since 2008. These ‘Finch Superflights’, which are defined as southern flights of all eight eastern irruptive finches, are rare, and this year, conditions have aligned and all species have moved in numbers, including the rarest of irruptives, the Pine Grosbeak.  Read more...
