I estimate that 215 bird species currently breed or have previously bred in Nebraska. This number compares with a total of 330 spe¬cies that breed or have bred in the Great Plains region south of Canada, as I defined that region in my book on the breeding birds of the Great Plains (Johnsgard, 1979). An analysis of the relative species diversity of Nebraska's breeding avifauna establishes several areas of unusual species richness and endemicity, these most important being the Missouri Valley and associated middle to lower Niobrara Valley, the Pine Ridge area of the northwestern Panhandle, and the entire Platte Valley.
Species of Birds Considered as Pandemic Breeders Across Nebraska include Pied-billed Grebe American Bittern Great Blue Heron Black-crowned Night Heron Canada Goose Mallard Northern Pintail Blue-winged Teal Red-tailed Hawk American Kestrel Northern Harrier American Coot Killdeer Rock Dove Mourning Dove Yellow-billed Cuckoo Barn Owl Great Horned Owl Long-eared Owl Common Nighthawk Belted Kingfisher Downy Woodpecker Hairy Woodpecker Western Kingbird Eastern Kingbird Northern Rough-winged Swallow Bank Swallow Cliff Swallow Barn Swallow Blue Jay American Crow House Wren American Robin Gray Catbird Loggerhead Shrike European Starling Yellow Warbler Common Yellow-throat Blue Grosbeak Chipping Sparrow Lark Sparrow Grasshopper Sparrow Red-winged Blackbird Western Meadowlark Yellow-headed Blackbird Common Grackle Brown-headed Cowbird American Goldfinch House Sparrow
