Description: To guide monitoring of burrowing owls (Athene cunicularia) in the Coachella Valley, California, USA, we analyzed survey-method-specific seasonal variation in detectability. Point-based call-broadcast surveys yielded high early season detectability that then declined through time, whereas detectability on driving surveys increased through the season. Point surveys without call-broadcasts yielded the lowest detectability rates overall. To maximize detectability, we recommend coupling early season point-based call-broadcast surveys with late-season driving surveys. Occupancy models proved useful for integrating data from multiple methods to analyze distributional patterns while accounting for variation in detectability.
