Divers to Ducks
The only breeding divers (loons) in Norway are the Black-throated and Red-throated Divers. Yellow-billed and the Great Northern Divers are mainly winter and passage visitors. There are three breeding grebes; Slavonian (Horned), Little and the Great Crested Grebe. Red-necked Grebes are locally quite common winter visitors. Black-necked and Pied-billed Grebes are extreme rarities with respectively about 30 and two records (until 2003). There are no breeding shearwaters, but Manx and Sooty are recorded in various numbers each year. The Northern Fulmar breed at several islands in the west. European and Leach's Storm-petrels are rarely found breeding, but many European Storm-petrels are caught using play-back during early autumn. Northern Gannets are like the Fulmar quite numerous at certain islands (not more than ten colonies) scattered from Møre & Romsdal and north to Finnmark. Both the Great Cormorant and European Shag are numerous breeders in Norway. The Cormorant is more attached to Northern Norway than the Shag, which is more widespread along the coast. However, both are common during winter in most coastal areas. The only breeding heron in Norway is the Grey Heron. It can be found in quite dense colonies, mainly along the coast all the way north to Troms county. Two Swan species breed; Mute and Whooper Swan. Mute is a southern species, while Whoopers are northern. Lesser White-fronted (rare), Bean (rare), Barnacles (quite recent establishment in the southeast and Greylag (common) are the main breeding Geese species, but introduced Canada Geese can also be found pretty commonly. The Mallard and Teal is by far the most common dabbling ducks, and the Common Eider among the perching ducks. Asterisk (*) behind the English name indicates that the species is a rarity in Norway.
