The Delaware Valley Ornithological Club (DVOC) is one of the oldest ornithology organizations in the United States. Founded in 1890, the club has held regular meetings at the Academy of Natural Sciences of Philadelphia for over 125 years, and has published the periodical Cassinia since 1901. Membership is open to any dues paying person with an interest in birds. The club organizes birding field trips throughout the Delaware River valley region, including a dedicated year-round trip schedule within the city limits of Philadelphia (BirdPhilly).

Brief Description:  Jason will take us on a virtual tour of some exciting specimens housed at the Academy, focusing on a selection of birds that are extinct, endangered or (at least at one time) little-known. He will share some stories about the biology of these unusual birds and discuss why they are interesting or even unique.

Brief Biography:  Dr. Jason Weckstein is an associate professor in the Department of Biodiversity, Earth and Environmental Science (BEES) at Drexel University and associate curator in the Department of Ornithology at the Academy of Natural Sciences of Drexel.  He obtained his B.S. degree in Natural Resources from the University of Michigan in 1993, his M.S. in Zoology from the University of Minnesota, and his Ph.D. from Louisiana State University in 2003.  His dissertation research used DNA sequences to reconstruct the coevolutionary history and host-parasite associations between toucans and their ectoparasites.  After obtaining the Ph.D. he continued studying birds and parasites as a postdoctoral fellow with the Illinois Natural History Survey at the University of Illinois Urbana-Champaign and at the Field Museum of Natural History in Chicago, where he stayed on as a staff scientist until joining the BEES faculty in 2014.

Weckstein is a fellow of the American Ornithological Society and has authored over 60 peer-reviewed publications and delivered over 50 presentations at universities and at national and international scientific meetings.  In addition to his twenty years of experience at natural history museums, he has conducted research on birds and their parasites in the United States, Canada, South Africa, Ghana, Malawi, Nicaragua, Brazil, and Mexico.  In addition to providing teaching & training, and doing research, Jason’s additional interests at the Academy include collection-building, curation, and public outreach.

His current research program focuses on three main areas: 1) avian comparative biology and evolutionary history, 2) biodiversity surveys of birds and their parasites and pathogens, and 3) coevolutionary history of birds and their parasites.  His research involves both active field-collecting of bird and associated parasite specimens and analysis of DNA sequence data to reconstruct the ecology and evolutionary history of birds and their parasites.

BirdPhilly is an initiative of the Delaware Valley Ornithological Club. Founded in 1890, the DVOC has been based at the Academy of Natural Sciences of Philadelphia since 1891. The DVOC runs fields trips throughout the tri-state region, however BirdPhilly focuses on trips within in Philadelphia city limits in collaboration with Philadelphia Parks & Recreation and the Fairmount Park Conservancy.

Through BirdPhilly our goal is to increase interest and awareness of Philadelphia’s birds by providing quality birding experiences on expertly guided field trips. All field trips are free unless the site charges an admission fee. These trips are open to children, adults, and well behaved pets. BirdPhilly also participates in DVOC’s Philadelphia Bird Race to raise funds for conservation and research projects.

The club enthusiastically welcomes new members – young people, beginners and anyone else who is genuinely interested in birding. Members benefit from the wealth of information and expertise that this club offers. The bi-annual club journal, Cassinia, is provided to members.
