Meetings & Programs

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.

Laura Densmore is a second generation photographer. Her father ground his own lenses and built his own cameras during the depression. From a very young age she absorbed his lessons on composition and attention to detail.

Laura lives in Pennsbury, Chester County. She has traveled to numerous locations in search of birds. She has photographed: puffins on Skellig Michael and the Snaefellnes Peninsula in Iceland, various auks on St. Paul’s Island, which is closer to Siberia than to mainland Alaska, and gannets on Bass Island in Scotland.

Closer to home, she travels yearly to Florida for large wading birds, to south Texas for warblers and other migrating travelers, Arizona for desert birds as well as takes images out her back window.

She has studied with: Alan Murphy, Greg Downing, Ron Rosenstock and taken intense instruction from Rick Holt in Photoshop.

Her avian work tends to be portraiture and bird behavior in natural settings.

Ian Stewart - Ornithologist working at the Delaware Nature Society.
 

This presentation describes an experiment conducted recently in southeastern PA where most of the invasive non-native plants were removed from 10 woodland plots but left in place in 10 comparable plots to see if it affected their use by nesting birds. It also describes an observational study conducted in the fall to see if insect-eating birds prefer to feed in native or non-native plants. These results will be of interest to anyone involved in restoring habitat for bird conservation.

Presenter: Dorothy Bedford
 

When Dorothy Bedford’s sister started writing up her WWII family trilogy, based on her parent’s diaries and letters, Dorothy hadn’t dreamed of visiting PNG, where her father was an Army officer under MacArthur. As she got drawn into her sister’s research, the opportunity to visit in the guise of birdwatching became compelling.  Last August, Dorothy visited Port Moresby and the Western Highlands with P.I.B for Birds-of Paradise and other specialties. She’ll share photos and stories.

Katie Fallon
 

Vultures are often overlooked, underappreciated, and unloved, despite the vital roles they play in healthy ecosystems. Worldwide, vultures are primarily scavengers; they can help stop the spread of disease by quickly and efficiently removing dead animals from the landscape. Unfortunately, due to poisoning, direct persecution, habitat loss, and other threats, vultures are more likely to be threatened or endangered than any other group of raptors. But in the Western Hemisphere, Turkey and Black Vultures counter this trend and are increasing in number. Based on Katie Fallon’s recent book, this fun presentation will explore the life and times of the noble Turkey Vulture, including its feeding, nesting, and roosting habits, migratory behaviors, and common misconceptions. Katie will also discuss what it’s like to be up-close-and-personal with Turkey and Black Vultures through her work with the Avian Conservation Center of Appalachia

Club member John Mercer
 

A review of the trip I took with Hawk Mountain and ProNatura to view the River of Raptors in Veracruz, Mexico. A chronological travel log of what we did and what we saw, with pictures of birds, sites and interesting critters, but mostly birds. A terrific trip especially for raptor lovers, but we also did a lot of other birding and some cultural visits, making this a well rounded and delightful trip.

Club Member Brian Quindlen
 

The Upper Main Line YMCA in Berwyn, Pennsylvania is unlike most other YMCAs. It is situated on a 54-acre campus in the suburbs of Philadelphia. Twenty of these acres contain the Cassatt Preserve, which is part of the first conservation easement in the state of Pennsylvania. This property contains a unique history for both the habitats and the people who have enjoyed it over the last century. Serving first as a summer estate, then a Norbertine monastery, and finally a YMCA, this property would eventually be home to a robust youth birding program and environmental education center. This program is a tribute to history of the habitats, people, and birds that make this property special.

Brian “BQ” Quindlen is an avid birder, photographer, digiscoper, and educator from Malvern, Pennsylvania. As a Pennsylvania state certified K-6 elementary school teacher and K-12 environmental educator, BQ connects students with nature in a formal education setting. Also, BQ is the leader of the Garnet Valley Trailblazers nature program, an environmental education club and summer camp that takes students from first through twelfth grade birding.

Pat Sutton

Every-day gardeners who transition into wildlife gardening often have a hard time rethinking the many tasks they’ve tackled for years, tasks that are highly hazardous to the very wildlife they are working so hard to attract and benefit. Pat Sutton will open your eyes to a world of life hidden in fallen leaves, which to her are anything but leaf “litter.” She will uncover the secret lives of butterflies and moths, bumble bees and other beneficial pollinators, salamanders, fireflies and so much more through the winter months, all tucked safely in and under leaf litter. As late winter and early spring arrive, she will showcase the many native wildflowers that so easily bust through the deepest leaf litter and light up shade gardens throughout her yard.

Pat Sutton lives near Cape May, New Jersey, the world renowned migratory crossroads that is famous for its hawk, owl, songbird, shorebird, dragonfly, and Monarch butterfly migration. She has keenly studied the natural world for over 30 years.

Pat and her husband Clay’s landmark book, Birds and Birding at Cape May (Stackpole Books, 2006), is the in-depth result of their efforts over many years documenting and protecting the migration and the hometown that they so love. Pat and Clay Sutton together have co-authored How to Spot Butterflies (1999), How to Spot Hawks & Eagles (1996), and How to Spot an Owl (1994), all published by Houghton Mifflin Harcourt.

Pat has been a working naturalist since 1977, first for the Cape May Point State Park and then for 21 years with New Jersey Audubon’s Cape May Bird Observatory, where she was the Naturalist and Program Director (1986 to 2007). Pat has a Masters Degree from Rowan University in Environmental Education and an undergraduate degree in Literature from the State University of New York at Oneonta. Today, Pat is a free-lance writer, photographer, naturalist, educator, lecturer, tour leader, and wildlife habitat / conservation gardening educator. Pat is a passionate wildlife habitat gardener and advocate for butterflies, moths, bees (all pollinators), birds, dragonflies, frogs, toads, and other critters. Pat has taught about wildlife-friendly and native plant gardening for over 30 years. Sutton’s own wildlife garden is a “teaching garden” featured in many programs, workshops, and garden tours.
