what is it?

The black guillemot or tystie ( Cepphus grylle ) is a medium-sized alcid. The genus name Cepphus is from Ancient Greek kepphos , a pale waterbird mentioned by Greek authors including Aristotle. The species name grylle was the local dialect name for this bird in Gotland at the time of Linnaeus's visit there in 1741. The English word "guillemot" is from French guillemot probably derived from Guillaume , "William".
