Pennsylvania Society for Ornithology's
County Lists
Select a county below to view the list that has been compiled so far. These lists are VERY incomplete, so we need your help to fill in the blanks!
The list includes every species on the Official List of Pennsylvania Birds with 'Occurs' or 'Breeds' next to each species recorded for that county.
A 'Occurs' means it has occurred at least once in the county. A 'Breeds' means it has bred in the county.
Hybrids, subspecies, etc. are not included on these lists. We hope to have a sublist later to include those categories, but for now we are focusing on full species.
Please send additions and corrections to PSO@pabirds.org
For rare birds, a location and date would be appreciated (but not required) so we can look it up in the literature.
