This data-set comprises validated species occurrence records of Birds with odd plumage of the African continent. It is a collection of data from citizen science contributions. Records range from 2003 to present.

Birds with all sorts of unusual plumage variations are observed from time to time. Nowadays, with digital photography, pictures of these birds are frequently available. BOP (Birds with Odd Plumage) aims to provide a place where the photographs can be curated into one database. Any bird with any unusual plumage characteristic qualifies for inclusion in the virtual museum. This will provide the opportunity to look for patterns. Do certain species have abnormal plumage more frequently than others? Do unusual plumage patterns occur more in some places than in others?

Identification of citizen science records, based on the photos uploaded, is done by a panel of experts in the relevant taxa. The taxonomy is kept up-to-date by the project coordinator.

All data is available to the public. Records are provided at the recorded precision, usually point coordinates. The coverage, as it would be expected for a specialist project, is very sparse for the whole of Africa.
