How many species of terrestrial birds are found in Nebraska?

Nebraska is home to approximately 450 species of terrestrial birds, making this choice the most accurate. The state's diverse ecosystems, which include grasslands, wetlands, forests, and agricultural areas, provide habitats for a wide variety of bird species. These ecosystems support migratory patterns and nesting behaviors, contributing to the overall avian diversity in the state.

The number reflects the birds that are either permanent residents or seasonal visitors, highlighting Nebraska's importance as a stopover point during migration. This diversity also underscores the significance of conservation efforts to maintain these habitats, ensuring the survival of both common and rare bird species. In contrast, the other options represent figures that exceed the well-documented count of bird species recorded in Nebraska, thus they do not accurately reflect the state's avifauna.
