of the records, which are spread throughout the country. Many of the autumn birds have survived the winter under favourable conditions. 4. Porphyrula martinica. A very rare Nearctic guest, only two records (one from 1983) from the southwest and west, one from autumn (adult) and one from spring (probably one year old). 5. Fulica atra. This is the most common species with approximately 140 records. It has been found in all sea- sons, but like Gallinula chloropus most records are from November-Decem- ber (Fig. 7). The species has been found all over the country, most of the records are from the southwest, but also abundant in the northeast (Fig. 8), and survives commonly during the win- ter. Three breeding attempts are known. The first was in 1889 at Víkinga- vatn, NE Iceland. Seven eggs were collected and one bird shot (record no. 12). The second was at Hvítárvellir, W Iceland, in 1943. Only one bird was ever seen and six fertile eggs never hatched (no. 63). The third was in 1954 at Lake Mývatn, NE Iceland (no. 77). Most of the information on this breed- ing attempt is lost. One egg was col- lected, which probably was the only egg laid. There is also the possibility that eggs may have hatched before the single egg was collected. Whether a pair or just a single bird was responsi- ble for the nest was not confirmed. There probably was a second breeding attempt in a new place 2.5 km away from the first. A bird was observed with young, but it was not certain that the young belonged to this species. This breeding attempt remains a mystery. 6. Fulica americana. Very rare vagrant from the Nearctic, only two records, one from autumn in W Iceland (found freshly dead), and the other from late winter in SE Iceland (found long dead). 7. Grus grus. There are ten records from all over the country, half of which are from 1983. The number of birds is uncertain, as some of the individuals probably were sighted on more than one occasion. These are all spring and summer records. 156
