There are two levels of documentation possible for most species. Species without an asterisk may be observed or heard only; those observations will be considered reports (although verified records are preferred); observations supported by verifiable evidence (photographs, recordings, vouchered specimens) count as verified records. Those species shown with an asterisk require verification as the only level of documentation.
