Behaviorists sometimes view askance studies where researchers indirectly observe animals, consequently challenging whether remotely inferred behavior is true behavioral research. Alternatively, others purport that technological advancements, like Global Position System (GPS) tags or biologgers, have expanded the scope of behavioral research to temporal and spatial scales infeasible for direct observation. To spotlight strengths and shortcomings in approaches to behavioral research, we interrogated the use of techniques and their assumptions in foraging research, a behavior of interest to ecologists and behaviorists. We reviewed 604 foraging behavior studies to synthesize and compare foraging research across disciplines, taxa, and methods. We sorted approaches by the data they collect and their associated assumptions and determined that rather than two categories of direct vs. remote, there were five: direct observation, tracking, biologger, remote audio-visual, and remote spatial. Categories differed in their spatial extents, with remote spatial research having a much larger extent (up to 1.6 million km2) than direct observational or remote audio-visual studies. Remote spatial studies also spanned large temporal extents, but temporal coverage (the proportion of total study duration when data are actively collected) was lower compared to biologger research. Methods were also applied to different stages of the behavioral process of foraging: direct observations and tracking involved searching for resources at finer scales. 23% of studies used > 2/5 categories. A compound approach provided a more nuanced and complete description of foraging behavior. Thus, our understanding of behavior improves when multiple approaches are applied in conjunction to our question of interest.
