FAQ
Frequently Asked Questions
No. They are related (both in the auk family, Alcidae) but are different species. Puffins have colourful, triangular bills, while razor-billed auks have a black, vertically-striped bill.
They breed on rocky cliffs and islands in the North Atlantic, including the UK (e.g., Shetland, Orkney), Iceland, Norway, Canada (Newfoundland), and the northeastern USA (Maine).
The name refers to the laterally compressed, sharp-edged shape of its black bill, which resembles the blade of a cut-throat razor, especially noticeable from the side.
No. It is a very low-frequency, specialist term. An English learner is far more likely to encounter the word 'razorbill' in nature documentaries. Knowing 'auk' as a family of seabirds is sufficient for general purposes.
