Integrating multiple data sources improves prediction and inference for upland game bird occupancy models

Abstract: Bird populations have declined across North America over the past several decades. Bird monitoring programs are essential for monitoring populations, but often must strike a balance between efficiency of data collection and spatial biases. Species- or habitat-specialist-specific monitoring programs may be helpful for increasing efficiency of sampling and understanding effects of management actions, but may be subject to preferential sampling bias if they are used to assess large-scale occupancy or abundance an… Show more

“…eBird's data can be used to guide the planning of formal surveys, such as in the initial stage of the two-stage study design described by Pacifici et al (2012). Volunteer-collected data such as eBird's can also be combined with formally collected data from other sources in occupancy models (von Hirschheydt et al 2023), although idiosyncratic differences between data sources may need to be accounted for during modeling (Schindler et al 2022, Emmet et al 2023).…”

“…Regardless of how eBird's data are used, the variability in the data-collection process will need to be modeled (Johnston et al 2021), for example variation in the duration of observation periods, distance traveled during an observation period, and number of observers. Unless eBird's data are filtered to contain only point counts (Emmet et al 2023), the interpretation of “site” will depend on the range of travel distances encompassed in the data that are used. This is similar to the way that occupancy needs to be interpreted with any non-point counting (Altwegg and Nichols 2019).…”
