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).



  • Passing of a DVOC Member – Bill Stewart

    It is with sadness we report the passing of member Bill Stewart on Tuesday November 12, 2019
    Previous to becoming a DVOC member, Bill was the recipient of the 2014 Rosalie Edge Conservation Award in recognition of his ongoing conservation efforts in Delaware

    An article on his passing appeared in USA Today
    https://www.usatoday.com/story/news/local/2019/11/14/delawareans-mourn-loss-avid-birder-conservationist-and-coach-bill-stewart/4177745002/?fbclid=IwAR3IL9fdzl5GLk3nFFUDpf213Dzx_xFVSHe6NLKi2oFWJRoeaWNi67CrDWE

    Holly Merker wrote the following on PABirds
    “Many of you knew Bill Stewart, who spent a lot of time in PA, and inspiring PA birders. He recently Chaired the Frontiers in Ornithology Symposium in partnership with the PSO, and was the founder of the Delaware Bird-a-Thon, which has saved thousands of acres along the Delaware Bayshore, which the PSO supported through donations and efforts. Below is what I wrote to the Delaware birding community:

    “With great sadness I’m writing to let you know that we’ve lost one of the greatest forces in the Delaware birding community today. Bill Stewart, a true bird hero. Bill passed away today surrounded by his family, and his beloved Kim, while wrapped in tremendous love.

    Bill’s drive and fire in the effort towards bird conservation, locally, and globally, was unparalleled. His incredible determination to make things happen, get things done, all in the name of birds and birding, was like none other. While bird conservation, through land conservation and education, was foremost for Bill, he prioritized connecting the next generation of birders to conservation, and led by example.

    There’s no doubt he will be missed by so many of us, as he’s left his incredible mark on our community. But, what he’d want us to do is go forward, make things happen, get things done for the good of birds and conservation. But most of all, cherish every moment with birds and friends, be empowered by the spectacles of migration, go do what your heart inspires you to do.”

Speaker: Roger Pasquier

Birds in Winter is the first book devoted to the ecology and behavior of birds during the most challenging season of the year, when every bird’s focus is on survival. Winter may for many birds have had the greatest influence on their evolution and adaptations, from anatomy to migration. Winter affects not only the birds that remain in regions where it becomes cold each year, but also the migrants that go far to avoid the effects of cold, as well as the resident species with which they share habitat at their destinations.
At high latitudes, birds must cope with much shorter days to find food, stay warm, avoid predators, and secure shelter for the long night. Some that were solitary during the nesting season form flocks of their own or of many species with complex dominance hierarchies, others that in summer found all the food they needed for themselves and for their young in daylight become nocturnal. Migrants going short or long distances adapt to different ecosystems and communities of resident birds.

Roger Pasquier is an associate in the department of ornithology at the American Museum. My career was, in order, with the department, the International Council for Bird Preservation, the World Wildlife Fund, Environmental Defense Fund, and National Audubon Society. I have written a few other books, including Watching Birds: An Introduction to Ornithology, The Birds of the Republic of Panama, vol. 4, and Masterpieces of Bird Art: 700 Years of Ornithological Illustration.

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.

New Bins for New Birders (NB4NB)

Partnering with DVOC’s World Series of Birding Team’s corporate sponsor, Nikon Sport Optics, NB4NB is committed to supplying new, serviceable binoculars to organizations that expose young people to birding and the outdoors. We focus on those organizations that are local to the Delaware Valley Region: southeastern Pennsylvania, southern New Jersey, and Delaware.

Most of the funds are raised as part of the DVOC’s participation in NJ Audubon’s World Series of Birding but other donations are certainly accepted. All funds collected in a calendar year are distributed to one or more organizations recommended by the Conservation Committee and approved by Council.
