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).

Trip Leader: George Armistead

Free to all members and non-members

Enjoy a leisurely late afternoon stroll of the state’s number 2 eBird hotspot in terms of species diversity (with 303 species and counting). We will walk from the parking area to the observation tower, via the big boardwalk, and back while enjoying the nesting Yellow Warblers, the summer influx of herons, and hope for the odd early migrant as well.
Let’s meet at the covered pavilion by the parking lot.
If the weather looks questionable: check DVOC Facebook & BirdPhilly Chatter on Telegram.

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.
