Nobody likes unnecessary duplicates polluting their pristine sighting records! To prevent duplicates from being generated when importing from another platform, Birda automatically checks to see if the same sighting has already been imported. If a duplicate record is detected in an import, it is automatically excluded from the import.
This functionality allows users to keep their Birda records up to date by continually importing new sightings (to Birda) that have been logged via another platform.
Exceptions to the rule
If you import a record to Birda and then change the record in the source platform and reimport it, then it may create a duplicate as the edited sighting could be seen as a new distinct record. Let us know if this ever happens to you so that we can refine our de-duplication algorithm 😀
