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).



  • Update from the President – August 2020

    Members and Friends – I hope that you are all well and enduring the economic, health and social impacts in your lives. The COVID 19 pandemic continues to permeate all aspects of our lives and it looks like there is no end in sight. The DVOC Council has been working to address the challenges and improve our club’s mission and activities. I wanted to share the updates with you here. 

    Meetings

    The good news: We are prepared to hold DVOC meetings starting Sept 17th! We will get back to the business of the club followed by a presentation by Jim Wright who will discuss his new book “The Real James Bond” – a true story of identity theft, avian intrigue, and Ian Fleming.  
    The bad news: The Academy of Natural Sciences is closed to the public so we will not be able to meet in person.

Speaker: Jennifer Uehling

SPEAKER:  Jennifer Uehling

THIS IS A VIRTUAL MEETING, SO YOU MUST REGISTER TO PARTICIPATE:

 

 

The contiguous USA was once home to two native parrot species: the Carolina Parakeet and the Thick-billed Parrot. These species are now extinct here. However, over the past century, a diverse set of parrot species has been introduced to the USA via the pet trade, and 25 species have started breeding outside of captivity. This talk, based on a published paper and a forthcoming book chapter, will summarize information about the breeding species, including possible explanations for how they ended up breeding in their localities, and will provide vignettes from certain localities where parrots are especially common. This work was done in close collaboration with Drs. Stephen Pruett-Jones (University of Chicago) and Jason Tallant (University of Michigan).

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.




Each year the DVOC raises money for our Conservation Fund. 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.
