Species mistake statistics

Aggregates over quiz answers. With a country selected, only games played in that country are counted, and only species on that country's checklist are shown (excluding introduced, uncertain, and unknown).

Only species with at least 3 picks (times shown). Error rate = wrongly answered / (wrongly + correctly answered) when this species was chosen. When a country is selected, the minimum pick count is lower than for all countries.
