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.

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.

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.

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.
