Source and limits
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.
