What does "Most Probable" vs. "Rare Species" mean on the checklist page?
eBird automatically defaults to a list of species that should be encountered at the location and date that you've entered. This is the "Most probable" list of species you see initially. If a species is not represented on this version of the checklist click the "Rare species" link in blue. This gives you either the complete state or county list, and most birds encountered should now be present.
