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.
