March 20 Meeting -- The Endangered Cape Sable Seaside Sparrow

Please join Dr. Sean Murphy and the Tiadaghton Audubon Society for a presentation on the endangered Cape Sable Seaside Sparrow. The presentation will be at 7:00 pm following our 6:00 pm business meeting. Both meetings are open and free to everyone!  Our meeting and presentation will take place in the old music room in the Wellsboro Admin building. See directions below.

Dr. Sean Murphy joined the Wildlife Diversity Division of the Pennsylvania Game Commission in January 2018 and leads the Endangered and Nongame Birds Section. He received a Bachelor of Science degree in Biology (Ecology) from Penn State University and a Ph.D. in Biology from the City University of New York in 2010. His graduate work focused on the population biology of the American Oystercatcher near the northern limits of its range. 
Following graduate school, Sean worked as a Wildlife Biologist for the U.S. Geological Survey in Corvallis, Oregon. His work focused on the interactions between avian populations and their environment, which led to multiple studies on the population dynamics, life-history, and habitat use of a variety of avian species of conservation concern, including marsh birds, shorebirds, and seabirds.
Prior to joining the Game Commission, Sean worked for Conservation InSight where he helped develop a spatially-explicit population estimator for the federally-endangered Cape Sable seaside sparrow. He also helped in the implementation of new survey protocols to improve current data collection methods.

Sean is a member of the Wildlife Society, American Ornithological Society, Association of Field Ornithologists, International Wader Study Group, Waterbird Society, and the Pennsylvania Biological Survey-Ornithological Technical Committee. He is a past President of the Ornithological Societies of North America (OSNA) and currently serves as an elected council member for the Waterbird Society and their Diversity Committee. 
Sean currently lives in Williamsport and spends most of his free time with his wife and two young daughters. He enjoys hiking, biking, and birding. 
Directions - Drive past the main entrance of the Admin building, turn left and follow the building all the way around to the back.  You will pass a maintenance shed/building.  Go in the back entrance and follow the signs to the meeting room.

Tiadaghton Audubon Hosts Planetarium Open House Dark Skies Program Feb 1

The Tiadaghton Audubon Society will host an open-house "Dark Skies Program" this Friday, February 1, in the George B. Strait Planetarium under the gold dome of the Grant Science Center on the Mansfield University campus. The program is free. Attendees are asked to arrive by 6:45 p.m. At 7 p.m., Dr. Elaine Farkas, a physics professor with the MU Department of Chemistry and Physics, will take the audience on a 45-minute exploration of the winter night sky, including Orion's belt and distant galaxies. Because the Tiadaghton Audubon Society is one of the sponsors of this Dark Skies program, Farkas will also point out some of the bird-like constellations, such as Signas the Swan. Following the program, Tim Morey, Hills Creek State Park's natural resource specialist, will provide information about stargazing opportunities at Cherry Springs State Park and will discuss local amateur astronomy resources. If conditions allow, participants will take a brief trip outdoors to look through a telescope at the night sky. Grant Science Center is on the MU campus in an area of one-way streets. Just look for the planetarium's gold dome. After 4 p.m. parking is available in nearby employee lots, requiring a short walk to the Grant Science Center. For information, contact Dr. Farkas via email efarkas@mansfield.edu or call 570-662-4754.

January 12 Meeting to Feature Scott Weidensaul on Snowy Owls

Scott Weidensaul will be live and in person at the Wellsboro Area High School Auditorium January 12th 2:00 pm. Meet and greet along with book signing to follow his presentation
sponsored by the Tiadaghton Audubon Society -- free and open to the public.

Caught in the SNOWstorm

Five years ago saw the largest invasion of snowy owls into the eastern United States in perhaps a century, providing an unprecedented opportunity to learn more about these mysterious Arctic hunters. Author and researcher Scott Weidensaul will share the story of Project SNOWstorm -- how a huge, collaborative, publicly-funded effort focusing on snowy owls came together in a few frantic weeks and grew into one of the largest snowy-owl research projects in the world; it continues to make discoveries and unexpected insights into the life and ecology of this great white raptor.

Scott Weidensaul is the author of more than two dozen books on natural history, including the Pulitzer Prize finalist "Living on the Wind," about bird migration, "Return to Wild America," and "The First Frontier: The Forgotten History of Struggle, Savagery and Endurance in Early America." His newest book is "The Peterson Reference Guide to Owls of North America and the Caribbean." Weidensaul is a contributing editor for Audubon, a columnist for Bird Watcher's Digest and writes for a variety of other publications; he lives in the mountains of eastern Pennsylvania, where he studies the migration of owls and hummingbirds.

Birders and nature enthusiasts in Tioga County, Pennsylvania will join birders across the western hemisphere and participate in Audubon's longest-running wintertime tradition, the annual Christmas Bird Count (CBC),  to be held in our area on January 1, 2019. Over 2,000 individual counts are scheduled to take place throughout the Americas and beyond from December 14, 2018 through January 5, 2019. Tioga County through the Tiadaghton Audubon Society has been represented in the count every year since 1968.

The Christmas Bird Count began in 1900 when the founder of Bird-Lore (the progenitor of Audubon magazine), Frank Chapman, suggested an alternative to the “side hunt,” in which teams competed to see who could shoot the most game, including birds. Chapman proposed that people “hunt” birds only to identify, count, and record them. These “binocular brigades” often brave winter’s chill, ice and snow in order to record changes in resident populations and ranges. “When Frank Chapman started the Christmas Bird Census, it was a visionary act,” said Audubon President John Flicker. “No one could have predicted how important the CBC would become as a resource and tool for conservation.” CBC data also help document success stories. The Christmas Bird Count has helped document the comeback of the previously endangered bald eagle and significant increases in waterfowl populations, both the result of conservation efforts. “Each CBC volunteer observer is an important contributor, helping to shape the overall direction of bird conservation,” says Geoff LeBaron, Audubon's Christmas Bird Count Director.

In Tioga County, the count is conducted in a 177-square-mile circle centered in Whitneyville and encompassing Wellsboro in the west, Mansfield in the east, Ives Run/Hammond Lake in the north, and to just above Arnot in the south.

If you would like to participate, please message us on Facebook or contact us at tasmember@yahoo.com. More eyes are always needed, and great birding skill is not a requirement. In fact, if you live within the count circle, you can just count the birds in your backyard or neighborhood. Please join us on January 1.
