Welcome to the Pennsylvania Society for Ornithology (PSO) - a group of birders from across the commonwealth devoted to birding and wild bird conservation.

Our members range from neophyte birders to professional ornithologists. All are welcome!

PSO also encompasses the Pennsylvania Ornithological Records Committee (PORC) -- a group of volunteers tasked with maintaining the Official List of Birds for Pennsylvania and maintaining a record of rare birds seen in the state. Please submit rare bird observations at the following link: pabirds.org/records/ Uploaded video may appear on this channel.
