A total of 6 species of terns and one
auklet species have been recorded as vagr-
ants in Iceland. All known records of the-
se species up to December 1984, are listed
in this paper, except records of Black
Tern (see discussion below). The Black
Terns can considered as rare summer visi-
tors rather than vagrants.
The details included for each record are:
site (locality and county), date, sex and
age (if known), catalogue number
(RMxxxx) which is in use at the Icelandic
Museum of Natural History (if a specimen
is preserved there), observer(s), and first
literature citation. “ZM” means that the
specimen is preserved in the Zoological
Museum in Copenhagen. The common

1. Sandwich Tern (Sterna sandvicensis).
Two records, in April 1980 and June
1984.
2. Common Tern (Sterna hirundo). One
record of a newly dead juvenile from
late November 1964.
3. Forster’s Tern (Sterna forsteri). One
record from October 1959, the first
record of this species in Europe.
4. Sooty Tern (Sterna fuscata). One bird
found recently dead in June 1969.
5. Black Tern (Chlidonias niger). All
records of Black Terns have recently
been published (see Erling Ólafsson et
al. 1983, Erling Ólafsson 1986), and are
not listed in this paper. There are 31
records involving at least 32 indi-
viduals. Of four collected birds identi-
fied to subspecies, one belongs to C. n.
niger and three to C. n. surinamensis,
which appear to be the first records of
this nearctic race in Europe. Black
Terns have twice been found breeding
in Iceland, and raised young once (in
1984). Records are distributed from
May to October, but most of them
come from June and July.
