Treatment of the received dataset

We imported the received dataset with modifications as follows to better combine with other atlases or to match publication cited above:

  • Breeding code"/" in the original publication is shown as "E" in this website.
  • Black Vulture was included in the original publication with a species account and a blank map but it is excluded here because we do not include species without mappable data.
  • 9 species (Gadwall, American Black Duck, Green-winged Teal, Redhead, Ring-necked Duck, Lesser Scaup, Ringed Turtle-Dove, Long-eared Owl, White-throated Sparrow) and 2 hybrids (Brewster's Warbler and Lawrence's Warbler) were not mapped in the original publication but are included here because they were reported with breeding evidence of PO or higher.
