Thursday February 7, 2008, 7:30 pm

Program - Nathan Gregory, a graduate student at Princeton University. - "Impacts of Controlled Fires and Traditional Livestock Grazing on Bird Communities in Kenya"
When many people think of East Africa, they think of savannas - open, rolling grasslands with scattered trees and abundant wildlife. What they may not realize is that savannas are the products of a long history of human influence in the form of controlled fire and livestock grazing using bomas, temporary thorn-scrub corrals.
Nathan has been investigating how the two components of traditional pastoralism, fire and grazing using bomas, affect bird abundance,diversity, and community composition. Pastoralism as a way of life is declining, and this could have important consequences for conservation.

Thursday March 20, 2008, 7:30 pm

Program - Jeff Gordon - " iBird: Digital Technology vs. Natural History"
Many people think that one of the most valuable things about birdwatching is that it offers a chance to "unwire," to escape from things man-made into a more natural, authentic state. How does this notion fare in the days of ipods, laptops, and camera phones? What are the challenges and opportunities we all face as unprecedented power to collect and share information combines with increasing usage demands on decreasing natural areas?

While Jeff doesn't pretend to have all the answers to these questions, he does have a good deal of experience with birds, birders, and digital doodads. Join him for a conversation about the state of our art.

Thursday April 3, 2008, 7:30 pm

Program - David Errol Pattemore, "On the brink: Conservation of Endemic New Zealand Birds"
New Zealand has been long separated from other land masses and the bird fauna evolved in the absence of ground-dwelling mammals. Since the arrival of humans and associated mammal pests around 1000 years ago, 42% of endemic bird species have become extinct and a further 26 species are currently listed as 'Nationally Critical'. New Zealand's birds are largely unique and exhibit several common curious features such as extreme longevity, flightlessness and gigantism. The conservation of New Zealand's unique birds has involved dramatic and innovative techniques to bring populations back from the very brink of extinction. In this talk David will introduce you to some of New Zealand's weird and wonderful birds (including detail on the kakapo recovery program), describe the continued threats to their existence and detail the steps that are being taken to ensure that someday, even you may get a chance to see them.

Program - Debi Shearwater- "Penguins of the World"
Debi writes:
"I shot this image of expedition staff member, Kees Camphuijsen of Holland on one of our landings in South Georgia. He was so busy shooting images of King Penguins in front of him, that he did not notice this penguin that had approached his camera! This King Penguin was, literally, inches from his camera lens!"

"Kees then turned around and shot a pic of me, taking pics of the KINGS!"

Frank writes:"
Late in 2006, I decided to do a Philadelphia Big Year in 2007. Boy, I didn’t know what I was getting into. Birding practically every day in the city earned me 233 species, eight above Johnny Miller’s 1966 record. Along the way, I saw great birds and met a lot of wonderful people."

Program - Lillian Armstrong, "New Jersey Birding and Wildlife Trail Guides Project"
A peek inside the creation of New Jersey's Birding and Wildlife Trails.
After nearly 20 years on Wall Street, the last 14 of which were on San Francisco's version of it -- Montgomery Street, primarily in financial communications, Lillian Armstrong was ready for a change. Her passion for birds and the environment was nurtured through her volunteer efforts at the Golden Gate Raptor Observatory, and semi-annual trips to Cape May to visit her birder-parents. It was through sheer luck and serendipity that the fledgling NJ Birding and Wildlife Trails program had a brand new position open just as she resigned and turned over the reins of the practice she had built to one of her colleagues. She started with NJAS August 1, 2004, and the last four years have flown by.

Program - Adrian Binns - "Watching East Africa's Unique Wildlife"
From the savannahs of Kenya to Uganda’s rainforest, from the Ngorongoro Crater in Tanzania to the lakes in the Rift Valley, the abundant display of wildlife in East Africa is unparalleled. With such a large concentration of both mammals and avian species it is not surprising that a number of different inter-actions and relationships can be found between them. We will explore some of these unique relationships and take a look at some of the 14 (of 16 African) endemic avian families that East Africa hosts.

November 20, 2008, 7:30 pm - Annual Banquet

Program - Clay and Pat Sutton, "Birds and Birding at Cape May (a Bird Walk Through Time)," program and book signing by Clay and Pat Sutton

The husband and wife team of Clay and Pat Sutton are long-time naturalists whose names are synonymous with Cape May, New Jersey, a place that has been aptly called the migration capitol of North America. Pat Sutton was for 21 years the Program Director at the New Jersey Audubon Society’s Cape May Bird Observatory. Prior to that, she was the Park Naturalist at Cape May Point State Park. Pat is a founding board member of the North American Butterfly Association.

Clay is a life-long resident of Cape May, where he has worked as an Environmental Program Administrator, Vice-President of an environmental consulting firm specializing in threatened and endangered species, and for the past decade as a self-employed naturalist and field biologist. He is a long-time instructor for the American Birding Association’s Institute for Field Ornithology. Today, Clay and Pat are free-lance writers, naturalists, lecturers, and tour leaders.

Pat’s consuming interests include owls, butterflies, and wildlife gardening and wildscapes. Clay is captivated by migration in all its forms.

Clay and Pat have had papers published in a number of journals and proceedings, and have contributed numerous popular articles to virtually all of the popular birding magazines. Clay is a co-author, with Pete Dunne and David Sibley, of the instant classic Hawks in Flight (Houghton Mifflin, 1988), and Clay and Pat together have co-authored How to Spot an Owl, How to Spot Hawks and Eagles, and How to Spot Butterflies, all published by Houghton Mifflin.

Their landmark book, Birds and Birding at Cape May, was published in 2006 by Stackpole Books, the in-depth result of their efforts over many years documenting and protecting the migration and the hometown that they so love. Their program will share the history of birds and birding at Cape May, including DVOC and Philadelphia's major roles.

December 4, 2008, 7:30 pm

Program - Scott Weidensaul, “Of a Feather”
From the moment Europeans arrived in North America, they were awestruck by a continent awash with birds - great flocks of wild pigeons, woodlands alive with brilliantly colored songbirds. Join naturalist and author Scott Weidensaul as he traces the unpredictable history of bird study in America, from frontier ornithologists (one of whom barely escaped pursuing Apaches with a precious hawk egg hidden in his mouth) to society matrons who organized the first effective conservation movement; from luminaries like Alexander Wilson (a convicted blackmailer) and Audubon (an accomplished liar) to modern geniuses like Roger Tory Peterson.
