7:30 pm - Bird Stack: Two Migratory Seasons at China by Mark Bonta
(via Zoom for an invitation link send an email to: Membership@bairdornithological.club
Mark Bonta was raised in central PA and went on to explore the remote corners of the planet through service to the Peace Corps and academic research at several small colleges. He has been involved in environmental conservation efforts in the Philippines, Australia, Honduras, Mexico, and the US. You can access his publications at https://markbonta.academia.edu/ and his eBird profile at https://ebird.org/pa/profile/NDE4MTI5/world.
Links from the presentation:
“When the weather is just right along China's NE coast, birds migrating on the East Asian-Australian Flyway pile up on the tips of peninsulas. Fallouts and other phenomena give these special places their reputations as "bird stacks," none more famous than Laotieshan (Old-Iron-Mountain) at the southern tip of the Liaodong Peninsula. Purely by serendipity, I landed a teaching job in the shadow of Laotieshan in 2018, at the Liaoning University for International Business and Economics. During one glorious year, I recorded 133 species on campus ponds, forest, and fields, and gained valuable insights to the threats and opportunities facing Chinese bird conservation. Along the way, I saw clouds of Amur Falcons appear and disappear as if by magic, thousands of Chestnut-flanked White-eyes streaming over for days on end, orioles, bulbuls, snipes, flycatchers, grosbeaks, and Phylloscopus leaf warblers all over the ground and trees, and even Siberian Rubythroats flying into open classroom windows. Join me for a slideshow on this spectacle, and a sobering assessment of the future of birds in one of the most biodiverse countries in the world.”
Oct. 9 Doug Gross will present via ZOOM his program which was canceled in the spring. “The State of Pennsylvania's Boreal Conifer Forest Birds” - Doug Gross Pennsylvania mountain conifer forests, found primarily on glaciated parts of the Allegheny Plateau, are dominated by spruce and hemlock, but are diminished from pre-settlement forest. Unlike other Appalachian spruce forests, some of those in Pennsylvania harbor Yellow-bellied Flycatcher and Blackpoll Warbler (both PA Endangered). Other species of state conservation concern in this habitat include Swainson’s Thrush, Northern Waterthrush, Canada Warbler, Red Crossbill, Whitethroated Sparrow and formerly Olive-sided Flycatcher. These boreal conifer forests also host numerous other northern species having high continental conservation priorities and PA Species of Greatest Conservation Need status. Doug Gross, a biologist recently retired from the Pennsylvania Game Commission, will introduce us to some of these species and speak of management plans for this threatened ecosystem.

Nov. 13 “Life in the Avian Slow Lane” - Keith Bildstein, PhD. via ZOOM
Retired Director of Acopian Center of Hawk Mountain Sanctuary, is the author of several volumes on raptor migration ecology. Keith is presently working on his next book presently titled “The Secret Ecology of the World’s 23 Species of Vultures and Condors”. This presentation will be a review of his work with vultures and condors.

Dec 11, 7:30 pm - Insect Apocalypse by Dr. Ashley Kennedy Via ZOOM. (Joint meeting with Mengel Natural History Society)Your yard might look beautiful, but how do you know if it's contributing to the local ecosystem? Numerous studies from around the world suggest that insect populations are in decline, and that affects birds who rely on insects for food. Dr. Ashley Kennedy will show how food webs connect plants, insects, and birds, and how you can convert your yard into better wildlife habitat for these groups.
Dr. Kennedy earned her doctorate at the University of Delaware's Dept. of Entomology and Wildlife Ecology. She is a board-certified entomologist, a Science Policy Fellow of the Entomological Society of America, and a member of the Delaware Native Species Commission. She currently researches tick-borne diseases at the Army Public Health Center in Edgewood, MD.

Feb. 12 “Broad-winged Hawk Migration Ecology: Flying from Pennsylvania to Peru” - Laurie Goodrich Sarkis Acopian Director of Conservation Science at Hawk Mt. Sanctuary Hawk Mountain has tracked adult and juvenile Broad-winged Hawks throughout their life cycle from 2014 through 2019. Broad-winged Hawks have declined in southeastern Pennsylvania but remain common in more heavily forested regions. Hawk Mountain's study is only the second study to use satellite-telemetry with Broad-winged Hawks and the first to tag males. The talk will detail some of the key findings on range, migration ecology, stopover and wintering sites as well as emerging conservation threats.

BOC 100TH ANNIVERSARY BANQUET PROGRAM
Below is a press release from Scott’s publisher describing his latest book, which will be available for signing and sale
A World on the Wing
The Global Odyssey of Migratory Birds
by Scott Weidensaul (Author)
An exhilarating exploration of the science and wonder of global bird migration.
In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. Certain species, such as thrushes, avoid dehydration by “drinking” from their own muscles and organs, extending their flight range by more than two thousand miles; it now seems all but certain that birds orient themselves using Earth’s magnetic field through a form of quantum entanglement that made Einstein queasy.
These and other revelations convey both the wonder of bird migration and its global sweep, from the mudflats of the Yellow Sea in China to the remote mountains of northeastern India to the dusty hills of southern Cyprus. This breathtaking work of nature writing also introduces readers to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges.
Scott Weidensaul is the author of nearly thirty books, including the Pulitzer Prize finalist Living on the Wind. A writer and re-searcher specializing in birds and bird migration, he is a native of Pennsylvania now living in New Hampshire.
* The status of the COVID-19 pandemic in spring of 2021 will determine whether or not BOC will be able to hold our traditional banquet. As of now, we intend to celebrate our 100th anniversary with a banquet, and Scott Weidensaul, our most popular speaker, has agreed to present the program.. Final banquet details will be published in the Spring, 2021 Distelfink. Save the date.
