The Top 100 showcases your list totals within the eBird community, alongside the totals from other eBirders for any county, state, province, or country in the world. You can view Top 100 totals by year or lifetime for species or complete checklists, so even if you aren't traveling to chase down every new species you can still take pride by pushing your checklist totals higher!
NOTE: Top 100 totals are the same as those in your My eBird account: eBird does not "police" lists and our eBird data quality review does not affect these totals. The Top 100 is updated nightly (see the "last updated" time at the top right) so your totals may not be current immediately after entering a new bird. eBirders may opt of Top 100 under preferences.
