For a sighting in 1988/89, Ebels et al (1999) stated that the subspecific identity was impossible to determine without taking measurements. After examination of identification literature and scrutinising many photographs, the committee found this to be true for the 2019 sighting as well. The subspecific identity was considered crucial for the status assessment. While the potential of subspecies caspius wandering to north-western Europe is perhaps not overwhelmingly convincing, it is at least conceivable. P p poliocephalus from the Indian Subcontinent can, however, be fairly safely excluded as a potential vagrant. With the subspecies unknown, combined with a track record of proven and suspected escapes, this sighting was not accepted on status. | |
