Year-by-year evidence
Each year uses the same county and seasonal period. An exported zero does not prove absence. Unknown means the species row, frequency or checklist sample is unavailable. These records do not estimate your chance of finding the bird or establish rarity.
This county-wide sample pools the selected years. It does not establish how regularly the species returned each year, how likely you are to find it at this spot, or whether this flock size is unusual. Percentages can be unstable when few checklists are available. Habitat, observer effort and repeated visits affect reporting. A zero does not establish absence.
