Résumé :	This paper reports on 47 of the rarest and most endangered bird species breeding in Denmark, monitored by the Danish Ornithological Society in 1998. This was the initial season of a project aiming at collecting data on these species each year during the breeding season. The project is organised as a network of coordinators, each of which takes care of a particular species. After the breeding season data are sent to a central coordinator who prepares the final report. Not all species included in this report were satisfactorily covered in 1998. Data are particularly sparse for dispersed breeders in forests (Turtle Dove, Lesser Spotted Woodpecker, Willow Tit, Golden Oriole). Data on Quail, Savi's Warbler, Great Reed Warbler, Firecrest, Nutcracker and Serin are likewise incomplete. Fulmar Fulmarus glacialis: bred for the first time in Denmark in 1998. Two pairs laid at the cliffs of Bulbjerg in northwestern Jutland, but none of them succeeded in hatching the egg. Black Stork Ciconia ni gra: no indications of breeding in 1998. The status of the species in Denmark is uncertain. White Stork Ciconia ciconia: 3 breeding pairs and 9 young fledged, with single storks at two additional sites. The species is very close to extinction in Denmark where no artificial breeding or release of storks is practiced. Spoonbill Platalea leucorodia: 3 breeding pairs and 7 young fledged at Limfjorden in northern Jutland. Recolonised Denmark in 1996. Barnacle Goose Branta leucopsis: 29 confirmed or probable breeding pairs, most of them (27) at Saltholm in Oresund near Copenhagen, the remaining 2 pairs on Bornholm. Wigeon Anas penelope: 2 confirmed breeding pairs at Vejlerne and Tipperne, respectively. Goldeneye Bucephala clangula: 66-71 breeding pairs, one in the southern part of Jutland, the rest in northern Zealand. All but one in nest boxes. Goosander Mergus merganser: 34-36 breeding pairs, all but one in nest boxes in the southeastern part of the country and - for the first time - a single pair on Bornholm, where nest boxes were introduced 2 years earlier. Red Kite Milvus milvus: 21 breeding pairs, 17 in Jutland and 4 on Zealand. White-tailed Eagle Haliaeetus albicilla: a new breeder since 1996, the species is doing well, with 5 pairs in 1998; one pair failed, the other 4 raised a total of 6 young. Golden Eagle Aquila chrysaetos: not yet breeding in Denmark, but a pair established in northern Jutland since 1996 may initiate breeding soon. Hen Harrier Circus cyaneus: only 2 breeding in 1998, both in the northern Wadden Sea area; recolonization in Denmark took place in 1992 in the same area. Montagu's Harrier Circus pygargus: about 35 breeding pairs, all located in southwestern Jutland with 20 km from the Wadden Sea. Osprey Pandion haliaetus: one pair failed at the only confirmed nest site in recent years, producing young in 1994 and 1996. Juveniles accompanying adults at about 9 sites suggest the possibility of other Danish pairs, but no acti ve nests were found. Hobby Falco subbuteo: only one confirmed breeding pair, with 3-4 additional sites where birds were seen in June-July. Black Grouse Tetrao tetrix: No breeding records, but a few observations of single adult birds at two former breeding sites in western Jutland. The species has all but disappeared from Denmark. Corncrake Crex crex: at least 80 birds were recorded, the highest number since the 1970s; no confirmed breeding, but some pairs may have nested at 3 localities where 4-6 calling males were present in May-July. Quail Coturnix coturnix: data incomplete, but calling males were heard in above average numbers. Crane Grus grus: 11-13 breeding pairs at 10 sites; 8 successful pairs fledged
