How many species of birds can be found in Nebraska?

Nebraska is known for its diverse avian population, encompassing various habitats that attract numerous bird species. The correct choice of 450 species reflects the extensive surveys and studies conducted in the state, which reveal that Nebraska serves as a significant stopover and breeding ground due to its unique geography, including wetlands, grasslands, and agricultural areas.

Each year, the state provides ideal conditions for both migratory and resident birds, contributing to this rich diversity. The number takes into account not just the birds that are commonly seen, but also those that are transient during migration, as well as species that may only occasionally be observed. The other figures provided do not capture the full breadth of Nebraska's ornithological richness, which includes both winter residents and summer breeders. Hence, 450 species is a well-supported estimate based on ornithological research and observation within Nebraska's varied ecosystems.
