The hooded crow was considered by most authorities to be a geographical races of the carrion crow as hybridization occurred where their ranges overlapped. However, in 2002, the hooded crow was elevated to full species status after closer observation showed that hybridisation was less than expected and hybrids had decreased vigour.
It continues to be a scarce bird in Pembrokeshire, with up to half a dozen records a year, mostly of single birds, and sometimes of long-staying individuals. The majority of records are from the St Davids to Fishguard area, although records from the south are becoming more frequent.
