Pennsylvania eBird comparison

Drew WeberAnalysis, eBird2 Comments

After posting the graphs of eBird submissions in Centre County I ran through the View and Explore Data part of eBird and did the same thing for Pennsylvania. The comparison is interesting because it shows that quite a few people across the state have kept detailed lists and entered these historical sightings back at least several decades. If anyone has been keeping detailed lists in Centre County (or really any other county) I would be happy to help you import them into eBird. Any sightings from before the launch of eBird in 2002 are useful as they help to fill in the gaps.

The monthly comparison is interesting because in every month, eBirders across Pennsylvania report roughly 100 more bird species than do eBirders in Centre County. I think this would likely be the case for most counties in Pennsylvania.

Does anyone else pick anything interesting out of these charts? Are there other charts you would like to see? Hopefully these types of numbers will be easier to pull out of eBird in the future so I don’t have to do it manually.
