presently known and sight records which
can be dated and located with certainty. Be-
cause these pelagic species are passage
migrants in Iceland waters, there are many
old and also recent general comments, which
are briefly mentioned in this article, but
cannot be included in a list.
All records from 1979 on have been re-
viewed by the lcelandic Rarities Commit-
tee and published from 1981 in its annual
reports in Bliki (Gunnlaugur Pétursson &
Kristinn H. Skarphéðinsson 1983, Gunn-
laugur Pétursson & Erling Olafsson 1984,
1985, 1986, 1988, 1989a, 1989b, Gunnlaug-
ur Pétursson, Gunnlaugur Þráinsson & Erl-
ing Ólafsson 1991, 1992a, 1992b, 1993).
These records from 1981-1991 are not list-
ed in this paper, but nevertheless included
in occurrence maps and histograms.
The details included for each record are:
site (locality and county or distance from
land or coordinates), date, the number of
birds (if more than one), sex and age (if
known), catalogue number in a museum (if
a specimen is preserved there), observer(s)
or fírst citation in the literature. The
catalogue numbers are “RMxxxx” for the
Icelandic Museum of Natural History and
“ZM. xx.xxx” for the Zoological Museum
in Copenhagen.
Conventional notations are used for sex
(ð, 2) and age (ad, imm). Olher abbre-
viations include: “Fundinn (ný)dauður” =
found (newly) dead, “Náð” = the bird was
collected but no further information is avail-
able, and “einkasafn” stands for a private
collection.
There are no confirmed breeding records
of Long-tailed and Pomarine Skuas from
Iceland, contrary to some old published
records.
1. Pomarine Skua (Stercorarius pomarinus)
The Pomarine Skua was only recorded occa-
sionally before 1960, see Fig. 2 (2. mynd). lt
has been seen annually since 1974, and the
records have increased considerably in the last
decade. Many of these recent records are from
research vessels in the sea north of Iceland.
Most of the records include only one bird, but
there are quite a few records of two to three
birds together, a few records of 4-10 birds, one
record of at least 30 birds (in 1979), another
