Nebraska · MigratoryRail (Virginia rail & sora)

NGPC's own Birds of Nebraska Online species accounts (Silcock & Jorgensen, citing Jorgensen, Brenner & Greenwalt 2022, "A Tale of Two Complexes: Secretive Marsh Bird Abundance Differs in the Sandhills and Rainwater Basin, Nebraska," Wetlands 42:41) directly compare 2016-2017 call-broadcast survey detections in Nebraska's two major marsh-bird wetland complexes, and the two species split in opposite directions. Virginia rail is overwhelmingly a Sandhills bird: 255 detections in the Sandhills vs. only 12 in the Rainwater Basin, with the source describing Virginia Rail as by far the most abundant species detected in the Sandhills. Sora runs the other way, though less starkly: 171 detections in the Rainwater Basin vs. 47 in the Sandhills. The study attributes the split to diet (Virginia Rail favors insects; Sora favors seeds like Rainwater Basin smartweeds) and to likely higher agricultural-chemical loads in Rainwater Basin wetlands suppressing the invertebrate food base Virginia Rail depends on. Because Nebraska regulates both species under a single combined "Rail" bag limit and license, the Sandhills is the primary regional signal, matching the numerically dominant species in the combined bag, with the Rainwater Basin the secondary region carrying real if smaller breeding numbers, particularly for sora.
