Because none of these sight records mentioned the unique black-and-white pattern and a small number of diluted, all-whitish ravens have been observed in recent decades in the Faroe Islands, none of these are officially recognised as pied ravens. Consequently, 1902 is generally considered as the year of extinction for the pied raven.

As exemplified by
Skarvanesi's painting, which obviously was done from stuffed birds, the pied raven was an object of interest to collectors. During the nineteenth century, the pied birds were selectively shot because they could fetch high prices; the
