A total of 8 species of guils have been
recorded as vagrants in Iceland. All known
records of these species up to December,
1980 are listed in this paper and numbered
in chronological order. Records from
1981 — 1984, which have been published in
annual rare bird reports (Gunnlaugur
Pétursson & Kristinn H. Skarphéðinsson
1983, Gunnlaugur Pétursson & Erling
Ólafsson 1984,1985,1986), are also briefly

irregular winter visitor, and Larus minutus
can be considered as a rare summer visi-
tor. Larus sabini is probably a rare
through-migrant in Icelandic waters,
although there are relatively few
documented records.
The details included for each record are:
site (locality and county), date, the num-
ber of birds (if more than one), sex and
age (if known), catalogue number
(RMxxxx or RM Gnr.xxxx) which is in use
at the Icelandic Museum of Natural His-
tory (if a specimen is preserved there),
observer(s), and first literature citation.
The 1981 — 1984 records are included in
distribution maps and histograms.
Apart from the common notations for
sex (<?,$) and age (ad, imm), age is also
frequently described in terms of commonly
used terminology, such as á fyrsta hausti
(juvenile), á fyrsta vetri (first-winter), á
öðrum vetri (second-winter), ársgamall
(first-summer) and 2ja ára (second-sum-
mer), etc. “A.m.k” means “at least”.
Other abbreviations include: “FD” means
found dead, “N” the bird was coilected but
no further information is available, “ZM”
that the specimen is preserved in the
