This modeling framework allows us to account for variation in detection probability when estimating species occurrence. In contrast, occupancy models jointly model the ecological process of species occurrence and the observation process of species detection, but estimate these as separate processes. We modeled covariates that are known to influence detectability (e.g. duration, time of day) alongside covariates that influence occurrence. In Chapter 4, we used analytical approaches that accounted for variation in detectability. In this chapter, we’ll cover basic initial steps for applying occupancy models to eBird data. 6.5.2 Predictive performance: Magnitude.5.3.3 Exploring the effects of covariates on detection probability.2.5 Exploratory analysis and visualization.2.4 Accounting for variation in detectability.
