August is always an exciting time of year for eBird—when we update all eBird records with the latest scientific advances in bird taxonomy. New information on species limits can result in increases (splits) or decreases (lumps) in your list totals. Whenever possible, we change your records for you to match the expected species when a split occurs—this is one of the main services we provide at eBird. Expect 2018’s update in the second or third week of August.
