Comparisons of Gambel's quail survey methods conducted in 2016 within the Mohave Desert of California with results and summaries

April 2, 2021

Data includes results collected in the Mohave Desert during 2016 using three survey methods (acoustic recording units, camera traps, and call-count surveys) to detect gamebirds, primarily Gambel's quail (Callipepla gambelii) but also including records of mourning dove (Zenaida macroura), Eurasian collared-dove (Streptopelia decaocto), and chukar (Alectoris chukar). ARU data includes the Selections (portions of the recording identified as potentially containing a Gambel's quail call) and Detections (quail calls confirmed following audible and visual verification of the recording and spectrogram). ARU data provided is summarized into hourly segments where selections occurred among five study sites. Camera trap data includes summary of the number of individuals and number of individual photos that game cameras recorded when deployed at four wildlife guzzlers for 5 species of animal that were detected: Gambel's quail, mourning dove, coyote (Canis latrans), Agassiz's desert tortoise (Gopherus agassizii), and red-tailed hawk (Buteo jamaicensis). Call-count data consists of individual station visit records, including non-detections, among 10 roadside transects containing 12 equally spaced survey stations and include time of detection, estimated distance and direction to the call/observation and number of individuals detected (primarily related to visual detections).
