Pennsylvania's 3rd Bird Atlas is a project documenting the birds of the Commonwealth from 2023 to 2029. This project follows PA's 2nd Atlas, conducted 20 years ago in the early 2000's, and will help support the conservation of birds in PA. All birdwatchers can participate in the Atlas by contributing their observations of bird breeding and wintering anyway in the state.
