Most commonly seen birds in Pennsylvania

Most commonly seen birds in Pennsylvania

Stacker compiled a list of the most common birds seen near feeders in Pennsylvania using data from the Cornell Lab of Ornithology's Project FeederWatch. Birds are ranked by the percent of sites visited from Apr. 18 to Apr. 30. Ties are broken by the average group size when seen, any further ties were not broken. Data was collected at 386 count sites in Pennsylvania. States with less than 10 count sites were not included in rankings for each bird.

Project FeederWatch, a citizen science project where participants collect data on birds at their feeders, was founded in Ontario by Erica Dunn and the Long Point Bird Observatory in 1976. The project partnered with the Cornell Lab of Ornithology after 10 years to scale the project across the U.S. and Canada and now has over 20,000 participants.

The data Project FeederWatch collects is used by scientists to understand trends in bird populations. If you would like to participate as a FeederWatcher you can learn more about the project here.
