Read the evidence correctly

Records are evidence, not a complete biological picture.

Regional evidence shows where qualifying records were documented. It is not a count of birds, a biological range map, or proof of absence.

Record ≠ bird count: Record totals describe qualifying source rows, not abundance or population size.
No eligible record ≠ absence: Missing qualifying evidence does not establish that a bird is biologically absent.
Same region ≠ recorded together: Regional overlap does not mean records came from the same site or time.
