Sample coverage
Estimated richness projects how many species likely occur here in total, beyond what's been detected so far.
Chao1 asymptotic estimator; sample coverage (Good-Turing) is the estimated fraction of that total already represented in this site's recordings -- both computed from the same species-detection counts as the tiles above.
Species
Only recordings with a species-level result are counted.
Noise/no-ID/unidentified recordings are excluded.
Activity over time
Recordings per month
Bucketed by calendar month, server time (UTC).
Not adjusted to any local timezone.
Recordings per hour of day
Hour of day, server time (UTC).
Not sunset-relative (see the backlogged "H:MM before/after sunset" feature).
