J0R1, perfect illustration of jet-black adult male nominate fuscus, breeding on Svartskjeran near Ibestad, county Troms in northern Norway. This small colony (maximum 10 breeding pairs) contains a pure population of such dark fuscus birds. Complete moult still not started by mid-June and mid-July. Also included on this page: map with location, see below.

Primary moult probably finished, but hard to interpret from this single picture. P8 with a small white tip, P9 lacking a tip and a mirror, P10 maybe growing?
