Each species in the locations species lists are assigned a rarity score that is specific to the location. The score is from 0 to 9 with 0 being the least rare (most common) and 9 being the most rare (least common) for the location. Find out more information about our Location Feature here.

The purpose of this score is to give users an indication of how common or rare any species is at any given location. So a bird species that may be considered very rare in a country could be considered relatively common at specific locations.

0 = Likely to see this bird at this location.

9 = Unlikely to see this bird at this location, though it has been seen here before.

These scores are calculated using over a billion historic sightings records from the Global Biodiversity Information Facility (GBIF). Find out more about the GBIF here.
