We compiled the home range size of a representative selection of adult marine and terrestrial vertebrates: seabirds (n = 19), marine reptiles (n = 6), marine fishes (n = 20), marine mammals (n = 22), terrestrial birds (n = 95), terrestrial reptiles (n = 65), and terrestrial mammals (n = 616). We only accepted home range estimates that described > 75% of an adult individual's total utilized area. Home range sizes in our compilation were estimated by authors using a variety of analytical techniques, including kernel utilization distributions, minimum convex polygon estimates, and geometric estimation techniques. We primarily accepted studies that used satellite, radio, or acoustic telemetry to obtain data for home range size estimation, though estimates produced from visual observations were accepted if a species' home range was small enough that the author could accurately describe it in its entirety without issue (e.g., the 1.3x10-5 km2 home range of the 2 g lizard Anolis distichus). If multiple home range estimates meeting these criteria were available from different studies on the same species, we averaged these values. Likewise, we averaged values for different groups of individuals within a species (e.g., sexes) if these values were reported in a single study. Data on the adult body mass of all species included in the home range dataset were preferentially drawn from the primary literature source from which home range data were taken. If body mass data were not available in these sources, they were collected from alternate databases or from peer-reviewed publications.

Scientific names in this dataset were obtained from literature and include some misspelled names and unaccepted synonyms. These names were matched to species in several authoritative name sources. Taxonomic identifiers and match quality results can be found in the supplemental document "Species Name Match Results."
