Prior to its arrival in the Netherlands, this bird roamed widely in Britain from June 2018 until April 2019. Pied Crow is regularly kept in captivity, resulting in a series of proven escapees, while there is no ringing obligation for captive individuals of this species. In general, the committee still has questions over its true vagrancy potential. The species has been proven to leave continental Africa by using ships. Birds in, eg, Brazil, Canary Islands, India, Portugal and Spain are therefore considered to be ship-assisted. All this combined casted too much doubt on this bird’s provenance to accept it as wild. The committee is aware that the species is expanding its African range and that it has even bred in Western Sahara. If a clearer pattern of sightings in Europe emerges in the future this well-documented sighting may be reassessed. Annual Report 2021.|
