Boulder Audubon's next program is on this topic. Bryan Guarente Presents Meteorology and Zugunruhe - October 24, 2017 07:15pm - 08:30pm - Unitarian Universalist Church of Boulder
*7:15 p.m. October 24, 2017* *Bryan Guarente Presents Meteorology and Zugunruhe* Each spring and fall a cascade of hormones triggered by changing daylength lures migrant birds like a Siren’s song toward the poles or equator. This period, called Zugunruhe (migratory restless-ness), is the basis of bird migrations. Is it a misfortune that this migratory drive coincides with some of the most violent weather systems, or is it perhaps instead a gift when seen through the eyes of an efficiency seeking, meteorologist bird? In fact, the frenzied flow of high and low pressure weather systems, typical of spring and fall and found in the mid-latitudes (30° to 60°) gives rise to the winds that fuel migration. Understanding weather and how big-picture weather systems affect bird movements can be useful tools for birders seeking rarities, fallouts and other excit-ing migratory phenomena. Bring your internet-enabled device to participate in the quizzes during this talk. *Bryan Guar**e**nte *began birding at age 7 in Pennsylvania with his dad. He became an avid lister while at the University of Northern Colorado (B.S. in Meteorology), frequently visiting local haunts like Lower Latham Res-ervoir and Crow Valley Campground. Weather and bird migration came together while listening to night flights at the University of Illinois while getting his Masters degree in Atmospheric Science. Bryan now teaches Earth Sciences for Boulder’s online COMET Program. On Tuesday, October 3, 2017 at 1:36:07 PM UTC-6, Ted Floyd wrote: > > Hey, all.
