Maybe these observations are from before 1910?
Hmm! There will always be some crazy people. I think you can report this mistake to the admin. But don't know how. But the photographs section in Carolina Parakeet page has some very interesting clips from some Bird book.
INaturalist is very simillar to eBird but there are all animals and plants. Maybe because of this there are less observations. I reminded this thread because recently I downloaded iNaturalist app. Green numbers are eBird and red iNaturalist observations - genus Primolius
