Meetings & Programs

Michael Moore - President of the Delaware Ornithological Society
 

Many birders struggle with identifying sparrows, referring to them as LBJ's (little brown jobs) or sparrow sp. This talk will help you tackle this difficult group. It will discuss and then attempt to blend the two main approaches to identification, the Peterson System and the Cape May School, to lead you to sparrow identification confidence. Each of the 16 species of regularly occurring sparrows in this area will be compared and contrasted with some discussion of finding and identifying rarities.
 

Mike is a recently retired Biology professor. He was at Arizona State University for 27 years and then at University of Delaware for 11 years before retiring a couple of years ago. He has published nearly 100 papers in scientific journals on behavior and hormones of birds and reptiles. He worked as an intern at Manomet Bird Observatory in Massachusetts in college and then completed a PhD in Zoology at the University of Washington on White-crowned Sparrows. He started birding in Massachusetts at 11 years old and has pursued it passionately since with a special interest in identification challenges and chasing rarities, splitting his field time between birds and his other passion, odonates. He is currently President of the Delaware Ornithological Society, a Vice President of the Dragonfly Society of the Americas and an eBIrd reviewer for Delaware.
 

Bert Filemyr

Of the over 950 birds on ABA's North American Bird List, almost 100 have apostrophes in their common names. These birds are named in honor of some of our most famous North American ornithologists (Audubon's Shearwater, Wilson's Plover, Cassin's Finch, etc.). But some are named for little known people (Lucy's Warbler, Lincoln's Sparrow, Bicknell's Thrush, etc.) and some are even named in honor of people who never set foot in North America (Swainson's Thrush, Henslow's Sparrow, Bewick's Wren, etc.). Learn the fascinating stories behind the birds with apostrophes in their common names and the very human people who have been so honored.
 
Bert Filemyr is an active field birder both in the Delaware Valley and throughout North America. He has birded extensively in all 50 states. He has having seen at least 100 species in each of the lower 48 states plus several Canadian Provinces. Retired from a public school teaching career, he pursues his passion for birding while researching topics related to early American ornithology. He was a member of the championship Nikon/DVOC World Series of Birding Team, the Lagerhead Shrikes for many years. He co-authored, along with Jeff Holt the book "The Composite Prints of Audubon's Birds of America" and a major article on Alexander Wilson in the Wilson Journal of Ornithology.

Dr. Joseph M. Wunderle, Jr. - Editor-in-Chief of Journal of Caribbean Ornithology
 

To help understand how hurricanes affect birds and their habitats and resources, Dr. Wunderle's talk will summarize some of the direct and indirect effects of hurricanes on bird populations in the Caribbean. Dr. Wunderle and his colleagues have been "fortunate" in having baseline samples of populations and resources before the arrival of hurricanes on different islands and they have been able to re-sample in the storms' aftermath to enable before and after comparisons. His talk will identify some of the types of birds, habitats, and resources especially vulnerable to hurricanes as well as demonstrating some post-hurricane behavioral responses of birds. Although some Caribbean bird species such as the endangered Puerto Rican Parrot have been found to be highly vulnerable to hurricane-induced population declines, populations of other bird species have been found to be remarkably resilient to hurricane impacts. In fact, not all is doom and gloom.

Wunderle has 40 years of experience teaching and conducting research throughout the Caribbean where he focuses on ecology and conservation of migrant and resident birds. His dissertation (Ph.D., 1980, Univ. of Minnesota) fieldwork was conducted on Grenada where he also taught field courses in the nearby Grenadines. Afterwards, he taught for a year at North Carolina State University and taught with the Organization for Tropical Studies in Costa Rica. In 1982, he joined the University of Puerto Rico (UPR) where he taught and conducted research with his students for eight years before joining the U.S. Forest Service (USFS) as a Research Scientist working throughout the Caribbean, Central America, and Brazil. After 30 years with the USFS he retired, joined the board of BirdsCaribbean and returned to teaching ornithology for a semester at UPR, where he continues to advise graduate students. He has authored or co-authored numerous publications, including a field guide to the natural history of The Bahamas, based on his research and training of Bahamian students. He is a Fellow of the American Ornithological Society and a recipient of its Ralph W. Schreiber Conservation Award and a founding member and former president of BirdsCaribbean and a former president of the Neotropical Ornithological Society.

Dan Mummert - PA Game Commission’s wildlife diversity biologist for southeastern Pennsylvania

Since 2016 the PGC has been ramping up their conservation efforts for the American Kestrel throughout southeastern PA. This talk will provide information about these small, declining falcons and highlight some of the accomplishments made and information learned from this study. The talk will also help highlight the importance of teamwork in conservation projects such as this and explain how the success of this kestrel program has only been possible with the continued help of a dedicated team of partners and volunteers including the West Chester Bird Club.

For the past 18 years, Dan Mummert's work has been focused on the conservation of the state’s rare and declining species of birds and mammals. Before being hired by the PGC, Dan worked as a wildlife biologist in California, Utah, Arizona, Delaware, Maryland, and western Pennsylvania. Dan studied wildlife conservation in college and received his B.S. from the University of Delaware and M.S. from Northern Arizona University.

Note: This meeting will be held in person at the meeting house and via Zoom. Zoom signon will start at 7:15 to enable the meeting to begin at 7:30.

Sandy Lockerman
 

For the past 25 years, the Ned Smith Center for Nature and Art in Millersburg, Dauphin County has been conducting a fall migration project on PA’s smallest owl: the northern saw-whet owl. Sandy is a licensed bander with the project and she will discuss the project and some of the findings that they have discovered over the years.

R. Craig Hensley - Biologist with Texas Parks and Wildlife Department

Among the challenges birders find in the field are the LBJ's, those nearly identical (to the untrained eye) Little Brown Jobs, or the many sparrows found across North America. However, with effort and an eye for detail, our native sparrows can be readily learned and through that discovery, their subtle beauty, enjoyed. Join birder, educator and biologist Craig Hensley of Texas -- yes, Texas, for a look at the sparrows not only of Pennsylvania, but also take a peek into their diversity in Texas. And yes, have your field guide handy, for you will be challenged at the end!

Craig Hensley is a life-long educator, naturalist and professional biologist. He has been a birder since plucking cherries from the backyard tree for his mother's cherry pies, competing with robins for their deliciousness in his home state of Iowa. He has worked as an Interpretive Naturalist and educator from Minnesota, Iowa and Nebraska, to Kansas, Missouri and most recently, Texas. He has a B.S. in Fisheries and Wildlife Management and a M.S. in Zoology with an emphasis on birds. His experience with Pennsylvania, while limited, is memorable -- he remembers tall trees, lots of trees from one end of the state to another. One of his bucket list goals is to visit Hawk Mountain during migration. Craig is a father to two grown children (one a birder, one coming along ever so slowly) and five beautiful grandchildren.

Note: Due to circumstances this meeting will be held only on Zoom. Signon will start at 7:15 to enable the meeting to begin at 7:30.

Jennifer Houtz - PhD Candidate at Cornell University

Emerging evidence has revealed that gut microbiota (the microorganisms residing in the gastrointestinal tract) are essential for a wide array of host physiological functions in birds. But can gut microbiota influence the behavior of the host? This talk will discuss the potential for gut microbiota to influence the behavior of birds and how avian behavior can influence gut microbiota diversity. Our speaker, Jenn Houtz, will share results from her PhD work investigating this bidirectional relationship between behavior and gut microbiota in tree swallows.

Jenn Houtz is a PhD Candidate in the Department of Ecology and Evolutionary Biology at Cornell University. She is a National Science Foundation Graduate Research Fellow and a Cornell Presidential Life Sciences Fellow. Jenn received her B.S. in Animal Behavior from Millersville University of Pennsylvania, where she studied the development of gut microbiota in starlings and worked as an assistant on a project studying the social behavior of wire-tailed manakins in Ecuador. Her research interests include microbial ecology, stress physiology, behavioral ecology, and ornithology. As a first-generation student, she is also passionate about mentoring undergraduate researchers, teaching, and science outreach.

Keith Russell - Program Manager for Urban Conservation for Audubon Mid-Atlanti
 

Birds have been colliding with buildings and other human structures since the 19th century and much of the work that has been done historically to help us understand the phenomenon was done in Pennsylvania, and this includes pioneering research conducted in Philadelphia by the DVOC during in the 1890s. This talk will review what we have learned about the problem in Philadelphia and what has been done in recent years in Philadelphia to address it.

Keith Russell is based in Philadelphia where he works on a variety of bird conservation issues including bird collisions with human structures, birds and nocturnal lights, non-native plants, and migration stopover habitat. His work uses education, monitoring, research, advocacy, mitigation work, and habitat restoration to improve conditions for birds in ways that have also broadened engagement in the environmental movement.

Rob Fergus

People have been living and interacting with birds since before we were human. Many of the behaviors that we take to be inherently human—including walking upright, using tools, language, writing, music, dance, sewing, pottery, home building, and flight—were perfected by birds long before we became human. This presentation looks at the shared history of humans and birds and how we may have became human by copying these behaviors from birds in our shared environment.

Rob Fergus studies human-bird interactions and received his Ph.D. in geography from the University of Texas at Austin in 2008. Rob is the former executive director of Travis Audubon Society, founder of the Hornsby Bend Bird Observatory in Austin, Texas and former National Audubon Senior Scientist for Urban Bird Conservation. He currently teaches geography and environmental studies at Rowan University and is the past president and current vice-president of the Birding Club of Delaware County.

Luke Safford - Director of Engagement & Education for the Tucson Audubon Society

Elegant Trogon, Red-faced Warbler, Montezuma Quail, Violet-crowned Hummingbird…many of us remember the first time we saw one—whether in real life or in the pages of our Sibley or Golden Guide. We'll discuss what makes birding in the Tucson area so amazing and how to go about planning your first (or next) trip to the Sonoran Desert and Sky Islands of Southeast Arizona.

Luke's responsibilities include overseeing the Southeast Arizona Birding Festival, field trips and event programs, the Tucson Audubon Nature Shop, and student education opportunities. He started birding and keeping a lifelist when he was six years old in Washington State thanks to his grandparents. His favorite place to bird is at Sweetwater Wetlands where he's been leading a weekly walk with Tucson Audubon since he moved to Tucson in January 2015.
