    This is THE big issue for migrant birds here, and Dr. Klem is the expert. Join us Oct. 5th at the Academy to see how we can tackle this together.

    This is a free event, but you are encouraged to register with Wyncote Audubon here.

    For more details, see the attached flyer.

  • An Almost Complete Set of Cassinias Are Available

    Club Member Hart Rufe writes….
    “Jewel and I are in the process of cleaning out items we no longer need or use. The jewelry donated by Jewel at the DVOC party was one set of such stuff. We have an almost complete set of Cassinias going back to the very beginning for which we are looking for a good home. If DVOC can make any money from the sale of the set, so much the better. If you would like to know just which issues may be missing we would be glad to check this out for you. We would hate to just throw them out.”

    A collection of an almost complete set of Cassinias (The Journal of the DVOC) is a valuable historical resource. If you have an interest in the DVOC and the history of birding in the Delaware Valley this would make a wonderful addition to your bookshelf.
    Please contact Hart Rufe directly if you are interested. As Hart has mentioned above any payment will go to the club for any one of the current initiatives that you and Hart might choose.
    Contact Hart at hartrufe@gmail.com
    An opportunity like this rarely comes along. Do not hesitate if you are interested.

  • Donations to the DVOC Interns Fund

    At the recent Annual Picnic, hosted by Anita and Paul Guris, those in attendance donated $330 to the DVOC Interns Fund. This money was raised by a combination of methods including the sale of donated items and straight donations.
    The DVOC Interns Fund is a major initiative of the DVOC and supports interns in the Ornithology Department of the Academy of Natural Sciences of Drexel University.

  • Lisa Kiziuk - The Motus: Building a Northeastern Wildlife Tracking Network

    September 21, 2017 @ 7:30 pm - 9:00 pm
    The Academy of Natural Sciences of Drexel University, 1900 Benjamin Franklin Pkwy, Philadelphia, PA 19103, USA

    After more than a century of research, our understanding of the movement ecology of migratory animals is still surprisingly rudimentary. Yet understanding how animals move across the landscape is critical to preserving them in a rapidly changing world. A new generation of miniaturized VHF radio telemetry technology, coupled with a rapidly expanding network of automated receiver stations through the Motus Wildlife Tracking System (Motus), has the ability to bring greater precision and efficiency to the study of migratory species. However, the greatest drawback to the current Motus array is its limited geography and coastal nature.

    In 2016 we formed the Northeastern Motus Collaborative (NMC) to establish a network of wildlife tracking radio receivers across Pennsylvania and the interior Northeast. This project will expand upon the current array of towers, increasing researcher's ability to monitor interior flyways in the northeastern United States. Over the next three years, the NMC aims to complete three phases of tower construction: 1) Install a line of 18 towers across Pennsylvania from Philadelphia to Lake Erie by September 2017; 2) Expand the statewide Pennsylvania network to approximately 40 towers by the end of 2018; 3) In 2019, establish 30 or more towers northward in New York and New England, creating a more diffuse network across the Northeast inland region. Once a minimum threshold of stations within the overall network has been achieved, we will begin to deploy VHF nanotags on nesting and migrant Northern Saw-whet Owls (Aegolius acadicus) at Project Owlnet cooperator stations in New England and eastern Canada, allowing us for the first time to track their movement in real time across continental scales. Expanding the Motus network to cover the mid-Atlantic and Northeast will fill a critical geographic gap and will dramatically increase our ability to understand migration and habitat use by hundreds of species of migrants.

  • SPECIAL EVENT: Dr. Daniel Klem - Bird/Window Collisions: Historical Research and Contemporary Solutions

    October 5, 2017 @ 7:30 pm - 9:00 pm
    The Academy of Natural Sciences of Drexel University, 1900 Benjamin Franklin Pkwy, Philadelphia, PA 19103, USA

    NOTE: This meeting is in partnership with Audubon Pennsylvania and our friends at Wyncote Audubon. The location will be at the Auditorium and entry to the building will be via the front entrance.

    Daniel Klem, Jr. is the Sarkis Acopian Professor of Ornithology and Conservation Biology at Muhlenberg College in Allentown, Pennsylvania. Dr. Klem obtained his B.Sc. at Wilkes University, M.Sc. from Hofstra University, and Ph.D. at Southern Illinois University at Carbondale. He served in the US military during the Vietnam War and was awarded the Bronze Star Medal. Among other diverse avian investigations, for 44 years and continuing to the present he studies, writes, and teaches about the threat that sheet glass and plastic pose to birds. No other scientist has comprehensively studied and published research results documenting and preventing the lethal threat that human structures pose to birds. In his 1990 paper "Collisions between birds and windows: mortality and prevention", he calculated that between 100 million and 1 billion birds in the U.S. alone are killed annually by flying into windows. His research has influenced the design of buildings, not least the Niagara Falls State Park Observation Tower, on which he was a consultant. He holds several US patents relating to window design to protect birds. He is motivated by available and growing evidence that bird-building collisions are an important wildlife conservation, building industry, and animal welfare issue for birds and people worldwide. His presentation will provide an overview of this important conservation issue, addressing why the windows of our homes, commercial buildings, even iconic park visitor and bird research centers, in urban, suburban, and rural settings are so fatal to all birds in their immediate vicinity. He will offer us his unique history of studying this topic for over four decades and his current cutting-edge research. The goal has and continues to be to save more bird lives from windows. He will end by inviting colleagues and the audience to pose questions and offer comments.
