Talk:List of birds of Pennsylvania

Images
I see that you have chosen a range of excellent images. Would it be better to use photographs of birds taken in Pennsylvania? On occasion a particular subspecies is found in a locality and sometimes a different subspecies from a different location is shown in error on a page about a location. I have not checked the images for this sort of problem. Snowman (talk) 10:37, 3 January 2011 (UTC)
 * It would certainly be ideal for the photos to have been taken in Pennsylvania, but it is highly improbable that I could find a wide enough range of pictures to satisfy this. Other bird lists, including Featured Lists, have images taken other locations (even other countries). I have generally tried to select featured pictures on enwiki or commons. However, if you notice an picture of a particular subspecies which does not occur in this region, please feel free to change it. — focus  20:56, 3 January 2011 (UTC)
 * I do not know much about American birds, so I will not be able to check to see subspecies in the selected photographs are correct for this region. At least one list had to change images during FL nomination, because inappropriate subspecies were shown. Snowman (talk) 11:50, 13 January 2011 (UTC)
 * Photos on a state bird list should represent birds one could expect to see in Pennsylvania. An accidental species such as the Magnificent Frigatebird should not have a photo.   (I just marked that species as (A), you may need to double check this list against accidental species in the source).  Any rare species found almost exclusively in Pennsylvania might also rate a photo.  --Footwarrior (talk) 21:05, 18 January 2011 (UTC)
 * Thanks for that, that was a mistake, and I've removed the frigatebird image. If you find anymore like that please don't hesitate to change it or altert me on the talk page. Hopefully there aren't too many. :-) Focus (talk) 21:15, 18 January 2011 (UTC)

Pennsylvania Society for Ornithology
An article on the Pennsylvania Society for Ornithology would be very desirable. --DThomsen8 (talk) 13:35, 20 January 2011 (UTC)

July 5, 2020 revisions
Because of the large number of changes necessitated by the update to the Check-list of North and Middle American Birds which the American Ornithological Society published on June 30, 2020, the revisions to this article are presented here rather than in a long series of edit summaries. Changes are per the AOS unless otherwise noted.
