• CANCELED: FIELD TRIPS

    Due to the terrible weather forecast for Saturday, both the Wissahickon Wood Duck and Warbler Festival and the field trip to Cape May lead by Linda Widdop has been canceled.

  • Team Ridin’ Birdy to Participate in the World Series of Birding and Burlington County Bird Quest Simultaneously!

    From Tony Croasdale, Matt Halley, Robin Irizarry:

    Ridin’ Birdy will be participating in New Jersey Audubon’s World Series of Birding and Burlington County Bird Quest simultaneously on May 6th. We will be raising funding for DVOC’s BirdPhilly program and conservation committee.
    Unlike every other year we will not be using bicycles. This year proved very busy for our team so we had no time to prepare. Indeed, Matt Halley has just returned from a research expedition in Nicaragua. Other team members had other commitments. This year we are proud to welcome Robin Irizarry to our team!
    Our plan is to start at Amico Island before dawn, then get to Palmyra at 7 for the Burlington County Bird Quest; we will bird there until noon when the Bird Quest ends. After that we will head to the Pine Barrens and hit some of Burlington County’s only salt marsh to end the day. For the World Series of Birding we will be participating in the Limited Geographical Area category in Burlington County.
    Thank you for supporting us, as well as the DVOC’s outreach and conservation efforts!

  • Zoe Yost - Owling at the Moon: Explorations on Silent Wings

    June 1, 2017 @ 7:30 pm - 9:00 pm
    The Academy of Natural Sciences, 1900 Benjamin Franklin Pkwy, Philadelphia, PA 19103, USA

    Zoe Yost is a fourteen-year-old naturalist, writer, artist, musician, and yogini. An active birder since age six, she has presented at and co-led birding walks with the Delmarva Ornithological Society, raised over $5,000 for the Delaware Bird-A-Thon, and worked as a banding assistant for Dr. Ian Stewart. In addition to the East Coast, she has birded in California, Wyoming, Alaska, the U.S. Virgin Islands, the Western Caribbean, and Great Britain. An award-winning artist, she has participated in art exhibitions at the Wilmington Art Loop, the Delmarva Ornithological Society, the Entomological Society of America, and the Center for the Creative Arts. Zoe is also an award-winning pianist and violist and an avid writer.

    Owls, the silent wings of the night, have fascinated humankind for centuries, both in positive and negative ways. But, what becomes visible to the mind’s eye when this cloak of myth and speculation is thrown off? Chronicling both fact and fiction, enthusiastic owlaholic Zoe Yost takes her audience on a rollicking expedition through original photographs, artwork, and writing to shed light on these elusive owls, one of the dark’s most iconic inhabitants.

    Greeting cards of the presenter’s artwork and photography will also be available for purchase as a fundraiser for the 2017 Delaware Bird-A-Thon. (Card purchases are tax-deductible.)

  • White Clay Creek State Park

    May 28, 2017 @ 7:00 am - 8:00 am
    White Clay Creek State Park

    White Clay Creek State Park (WCCSP), Newark, DE
    Trip Leader: Matthew Halley

    May 28, 2017 — 7:00 AM
    DVOC is excited to offer for the first time, a field trip to observe color-banded Veeries (Catharus fuscescens) at the long-term study site of Dr. Christopher Heckscher, professor at Delaware State University (DSU). Halley is the Editor of DVOC, and a Ph.D. student and ornithologist at the Academy of Natural Sciences of Drexel University. He completed his MS degree under Heckscher at DSU from 2011–14.
    Several surprising discoveries have been made at the WCCSP site in recent years, including the first documentation that Veeries are not socially monogamous, but rather practice a rare cooperative mating system called flexible polygynandry (Halley et al. 2016). The discovery that the species has a third component to its annual migratory cycle — an intratropical migration (i.e., within South America) that was previously unknown — was made via analysis of data from light-level geolocator tracking devices deployed and retrieved by Heckscher, Halley, and their research assistants at WCCSP (Heckscher et al. 2015). DVOC members will have the unique opportunity to tour the study site with Halley (and maybe Heckscher, depending on scheduling), to learn about past and ongoing scientific research at the site, and to observe first-hand some of the color-banded individuals that have taught us so much about their species.

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.

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.
