AB Citizen science data on biodiversity has experienced signifcant growth, largely driven byadvancements in technology that facilitate data sharing. In recent years, mobile applications haveprovided a substantial boost to both the collection and sharing of this data. While this accessibleinformation is undoubtedly valuable, we must consider the numerous biases present in this data whenused for high-quality research. In this study, we analyse citizen science data for the birds of the IberianPeninsula, comprising over 23 million unique records after fltering for duplicates (i.e., instances wherethe same observation was uploaded more than once). Using a 10 × 10 km square grid, we presentinformation on well-surveyed cells (completeness) as well as temporal, taxonomic, geographical, andland use coverages. We found that the completeness of information is generally high, with bettercoverage around densely populated areas such as major cities and coastal regions, as well as popularbirding destinations, which are frequently visited. The Mediterranean ecoregion and wetlands exhibitthe highest levels of surveying. Furthermore, we observed an increase in temporal coverage sincethe 1980s and broad taxonomic coverage across all bird orders in the Iberian region. Our resultsunderscore the utility of citizen science for many locations, as expressed in 10 × 10 km cells. However,they also highlight the inadequate data completeness across part of the territory, particularly inforested or sparsely inhabited areas. These fndings not only identify cells suitable for bird diversityor conservation studies but also indicate areas where citizen-driven bird recording eforts should beencouraged
