Secretive marsh bird monitoring concludes
Annual marsh bird surveys wrapped up in May, producing results consistent with the success we've seen in the last several years.
This year's surveys detected four federally endangered Yuma Ridgway's rails: two individuals on the Las Vegas Wash and two at the mitigation wetland cells behind the Clark County Wetlands Park Nature Center.
Field staff identified two additional Yuma Ridgway's rails incidentally at a second Wash location.
Detections over the last several years have been fairly evenly split between the main channel of the Wash and the adjacent mitigation wetland cells.
The annual recording of multiple individuals since 2021 helps show the success of the stabilization and revegetation investments made by the Las Vegas Wash Coordination Committee.
