Bridget Butler, AKA 'Bird Diva', gives us more than we thought we would ever want to know about roadkill in Vermont. Bridget, Program Director at Cold Hollow to Canada, discussed her innovative citizen science initiative, WildPaths, created to understand how wildlife move across the landscape. We'll never look at roadkill (through your car window) the same way again, and you might just be persuaded to stop and snap a photograph to submit to WildPaths.

Introducing Homo naledi (click for video)
November 01, 2016
Suds & Science returned to the Norwich Inn on Tuesday, November 1st at 7pm. Paleoanthropologist Jeremy DeSilva, Associate Professor of Anthropology at Dartmouth College, introduced us to Homo naledi - a new human ancestor from the cradle of humankind in South Africa. Jeremy has studied wild chimpanzees in Western Uganda, early human fossils in Museums throughout eastern and South Africa, and his anatomical expertise-- the human foot and ankle-- has contributed to our understanding of the origins and evolution of upright walking in the human lineage.

The White-winged Diuca-Finch
May 10, 2016
Only one bird species is known to regularly nest on glaciers. The White-winged Diuca-Finch (Diuca speculifera) is not a species of the polar regions, but of very high elevations in the tropics. In the 1950s, diucas were sighted going into a Bolivian glacier at night to roost. Since then very little has been published, and little is known about the species. Beginning in 2003, we have been observing this species in Peru at Quelccaya Ice Cap, the largest tropical glacier on Earth. By 2008 we were able to publish information about the nests they built on the glacier, although not until 2014 did we find active nests. This month we are returning to Quelccaya on a mission to learn more about diucas, as part of a quasi-secret, two-week effort to document every aspect of their lives on film. Our presentation will discuss the excitement and complications of such work, at elevations over 17,000 feet. And if it isn't difficult and risky enough to anticipate the breeding season and document a species for which almost nothing is known, the Quelccaya region has been strongly impacted by the 2015-16 El Niño event. With warmer-than-normal conditions, and snow accumulation at 29% of normal for early April, will the birds nest earlier? Will this be a particularly successful breeding season for diucas? What will we learn about the many other species inhabiting the wetlands around Quelccaya? Join us for answers to these questions and more, just days after our return from Peru!
