One of the things most loved about birds is their wild array of plumage colors and patterns. Where does all that color come from? In this presentation, you’ll learn how pigments and microscopic structures in feathers create the kaleidoscope of beauty we find in the avian world. Topics covered include iridescence, molting and feather wear, the evolution of feather color, and the functions of feather colors.  Audubon Society of Northern Virginia presents.

Ivan Phillipsen is a professional naturalist guide with a background in scientific research. Amphibians and reptiles were his first obsession as a kid. He eventually earned a PhD in Zoology, working in the field of conservation genetics. Ivan’s love of nature has expanded to include plants, fungi, and all animals, including birds. Birds have become his greatest passion. He’s an avid birder, hosts The Science of Birds podcast, and co-owns a birding ecotour company.

Audubon Society of Northern Virginia and the Virginia Society of Ornithology are proud to present an author talk with New York Times Bestselling Author, Scott Weidensaul!

His recent book, A World on the Wing: The Global Odyssey of Migratory Birds, has captivated birders and non-birders alike with stories of astounding discoveries about the navigational and physiological feats that enable migratory birds to cross immense oceans or fly above the highest mountains, go weeks without sleep or remain in unbroken flight for months at a stretch.

For this lecture, author and researcher Scott Weidensaul takes you around the globe — with researchers in the lab probing the limits of what migrating birds can do, to the shores of the Yellow Sea in China, the remote mountains of northeastern India where tribal villages saved the greatest gathering of falcons on the planet, and the Mediterranean, where activists and police are battling bird poachers — to learn how people are fighting to understand and save the world’s great bird migrations.

Join naturalist and salamander enthusiast Matt Felperin, Roving Naturalist with NOVA Parks, for an introduction to the fascinating world of herpetofauna, or “herps.” Otherwise known as reptiles and amphibians, these largely misunderstood animals are admittedly not among the cutest of creatures, and some people just can’t stand looking at a snake.

But on closer examination, says Felperin, you might discover how fascinating (and even adorable) these animals can be. From frogs and salamanders to snakes, lizards, and turtles, discover what kind of cold-blooded critters can be found in the eastern United States. For example, did you know that the mid-Atlantic region hosts the greatest diversity of salamander species in the world? They include the endangered Shenandoah salamander, whose entire range is limited to three mountain slopes within Shenandoah National Park.

Felperin also uncovers some pretty amazing adaptations, such as wood frogs that become “frogcicles” and turtles that breathe out of their backside to survive the winter. And, he says, you may just find a new favorite animal.

Pesticides 101: How You Can Protect Birds and the Environment

/in , /by

Tuesday, June 7, 2022
4 – 5 pm
Webinar
Register here.

Join American Bird Conservancy’s upcoming webinar for a discussion on the impacts of pesticides, how existing regulations are working – or failing – to protect the environment, and how individuals can reduce pesticide use at home.

An estimated 72 million birds are killed by pesticides and other toxic chemicals every year. Birds are not the only victims – overuse of harmful pesticides has led to insect population declines and adverse human health effects.

Yet these dangerous chemicals are widely available and used for everything from food production to home gardens.

Speakers:

  • Edward “Hardy” Kern, Director of the Pesticides and Birds Campaign, American Bird Conservancy
  • Lori Ann Burd, Environmental Health Director, Center for Biological Diversity
  • Aaron Anderson, Pesticide Program Specialist, Xerces Society for Invertebrate Conservation

Moderator: Jordan E. Rutter, Director of Public Relations, American Bird Conservancy
