Cuckoo surveys conclude

Biologists conducted the last of three rounds of yellow-billed cuckoo surveys in August, concluding threatened and endangered bird monitoring in the Clark County Wetlands Park for the year.

They detected two federally threatened cuckoos over the course of the 2022 surveys.

The surveys are conducted by broadcasting the bird’s distinct contact call in riparian habitat containing stands of tall trees, hoping to elicit a response.

These detections add to the record number of threatened and endangered birds found along the Las Vegas Wash this year, including endangered Yuma Ridgway’s rails and southwestern willow flycatchers.
