PSO Webinars now available at




Greene County Birding Spotlight

PSO will be visiting Greene county on April 28 - May 1 for their county spotlight.


We started doing this last year and have done 3 of them and this will be the 2nd one for 2023.


More details to follow but hope others are able to help lead any trips, join trips or just ebird anything seen on those 4 days to help spotlight the birds and create more checklists in the county.


We now have 2 days of field trips lined up, check out the discussion tab on this event.


If you do birding on your own, all you have to do to help the cause is share your ebird checklists with PSO Birding Data.
