NÁTTÚRUFRÆÐINGURINN
173
Sænskur dýrafræðingur, Sven-Axel Bengtson að nafni, getur ljós-
höfðaandar stuttlega í yfirlitsgrein um fuglarannsóknir sínar við
Mývatn (Bengtson 1967). Lætur hann þar í ljós þá skoðun sína, að
líklega verpi strjálingur (allt að finnn pör) af íjóshöfða við Mý-
vatn. Þessi tilgáta Bengtsons verður að teljast mjög ótrúleg, enda
órökstudd með öllu. Öll þau gögn, sem fyrir liggja, benda til þess
að ljóshöfðinn sé aðeins flækingur hér á landi.

SUMMARY
Tlie American Wigeon (Anas americana) in Iceland
by Arnthor Gardarson, Museum of Natural History, Reykjavik.
In 1901 the British collector and dealer F. Coburn claimed to have discovered
the American Wigeon (Anas americana) breeding in Iceland. Coburn’s record
has generally been regarded as unsatisfactory (Hartert 1912—21, Witherby 1943).
Coburn (1901 a) stated tliat he obtained an adult male, and a female ancl three
downy young, of this species in Iceland, and that he saw also an adult male in
eclipse, an adult female witli five young, and another adult female. Evidence
is presented here tliat one of Coburn’s specimens was most likely an authentic
Anas americana, and that he got this specimen from the Reverend Árni Jónsson
at Skútustadir, Mývatn. Coburn’s specimens are apparently lost, hence nothing
