Treatment of the received dataset
We imported the
with modifications as follows to better combine with other atlases or to match publication cited above:
Included the following species that were not mapped in the published atlas but were reported with data of PO or higher:
Brandt's Cormoran, Trumpeter Swan, American Black Duck, Arctic Tern, Ancient Murrelet, Acorn Woodpecker, Sky Lark, Northern Mockingbird, Bohemian Waxwing, and Golden-crowned Sparrow.
Grouped the American Crow and Northwestern Crow as unid. Crow because they were mapped together in the published atlas.
Mapped the following species only at township-range level to match the published atlas:
Northern Goshawk, Golden Eagle, Ferruginous Hawk, Prairie Falcon, Peregrine Falcon, and Spottel Owl.
