How this is measured: eBird publishes, for each day, every species reported anywhere in Ontario. We count how many of the 7 days sampled (August 22–28, 2026) each species appears on and rank by that count — nothing here is estimated or modelled. Species tied on days are ordered by the total number of individuals in those records. Rarities work the other way round: rare bird alerts tell you when a bird that is not common shows up near you.
