SUMMARY Thejackdaw Corvus monedula in Iceland by Ólafur Karl Nielsen, Museum of Natural Hislory, Reykjavík. The Jackdaw is a rather frequent spring and auturan vagrant in Iceland. Icelandic records up to 1 July 1979 are listed bclow. [P. Nielsen is said to have collected a Jackdaw at Eyrarbakki, SW.-Iceland (Pear- son & Pearson 1895) in 1896 (Gröndal 1901). In his diary P. Nielsen states that he never saw or collected any Jackdaw in Ice- land. This widely quoted record is therefore rejected.) 1) One Stóru-Laugar, NE.-Iceland, spring 1901. (Havsteen 1931).* This bird has erroneosly been said to have been caught at Stóra-Tunga, NE.-Ice- land (Sæmundsson 1905). And Tim- mermann (1949) made two records out of this single specimen. 2) <S Reykjavík, 26 October 1910 (Sæ- mundsson 1911).* 3) One at Skaftafell, öræfi, SE.-Iceland, 15 October 1952.* 4) One seen at Fagurhólsmýri, öræfi, SE.-Iceland, 15öctober 1952. 218
