Distance too long

Some checklists may display this message:

Distance too long. This checklist has been flagged for covering a large distance. A more specific location is required for public display: this checklist and its observations do not appear in public eBird outputs. More information.

To display publicly in eBird, checklists must be plotted accurately in a way that adequately represents the area where the birds were seen. We do not display checklists with distances of 80 kilometers (50 miles) or greater in public output. Distances this long, or greater, can misrepresent bird ranges on our maps. Site-specific checklists that cover shorter distances, preferably less than 8 kilometers (5 miles), are ideal for eBird data entry. 

Locations that cover a long distance (here, for example, inland from the coast for a mostly-coastal species like Least Tern), can paint an incorrect picture for where the species actually occurs: masking the real inland records that are notable for the species.

Checklists that do not appear in public eBird output are also not used for science. To learn more please see our Public and Non-public Checklists for more information on how checklists are displayed and Understanding How to Plot your Location to understand best practices for location plotting in eBird.
