Black-throated diver, Gavia arctica

This bird is breeding in the arctic and boreal regions of Eurasia. The breeding population of the European Union, entirely restricted to Scotland, amounts to 150-160 breeding pairs and seems stable (Tucker & Heath). Elsewhere this species is decreasing due to habitat changes, increasing disturbance by humans, predation, decreasing fish populations following over-fishing and acid rains and oil pollution at sea.

Great Northern Diver, Gavia immer

This bird inhabits the lakes of the boreal regions of North America, Greenland and Island, moving to coastal waters in winter. The population of Greenland and Island – altogether about 3500-4000 birds – is wintering along the British and Norwegian coasts. Small numbers of individuals reach the coasts from Denmark to Portugal (SOVON Atlas van de Nederlandse Vogels).

Red-throated Diver, Gavia stellata

This diver has a widespread breeding distribution in northern Eurasia and North America. The breeding population of the European Union, entirely restricted to the British Isles and Denmark, amounts to 1400 breeding pairs and seems to be increasing (EBCC Atlas of European Breeding Birds).

Family PODICIPEDIDAE, grebes

Slavonian Grebe, Podiceps auritus

This bird has a wide distribution in the boreal regions of Eurasia and North America. Within the European Union it is known as a breeding species only from Scotland, where its population amounts 60 breeding pairs. The total northern European population is estimated at 6000-9000 breeding pairs and winters mainly along the coasts of the North Sea and on the central European lakes. A few birds reach the Mediterranean coasts. Despite important local fluctuations, the total population of this species seems quite stable (EBCC Atlas of European Breeding Birds).

Family PROCELLARIIDAE, petrels, shearwaters

Gon-gon, Pterodroma feae

This pelagic bird is known from only the Cape Verde Islands and Madeira. In this last archipelago it is wholly restricted to Bugio, the southernmost island of the Desertas group. Its European population doesn’t exceed 250 breeding pairs, but seems stable. On world scale, however, this species is considered as being endangered (Collar et al. 1994).

Freira, Pterodroma madeira

This pelagic bird is known from only Madeira. Its population has declined during the last decade, and is currently totalling only 20-30 breeding pairs. Consequently this species is seriously endangered (Collar et al. 1994).

Bulwer's Petrel, Bulweria bulwerii

This pelagic bird of the North Atlantic and the Pacific Ocean is breeding at Madeira, on the Azores and on the Canary Islands. Its European population amounts to about 7500 –10500 breeding pairs. Its most important colonies are located on Madeira where the species seems to be stable. The breeding colonies of the Canary Islands and the Azores are decreasing however (EBCC Atlas of European Breeding Birds).

Cory's Shearwater, Calonectris diomedea

The taxon diomedea is breeding in the Mediterranean Sea, mainly on the Balearic Islands and in the Adriatic and Aegean seas. The taxon borealis is breeding in the Atlantic Ocean, mainly at Madeira and on the Canary Islands and the Azores. It winters in the South Atlantic. The population of the European Union amounts to 135000-198000 breeding pairs, which represents about 85% of the world population of the species (Tucker & Heath). Its trends are badly known, since the species is difficult to census. An increase has been noticed in some protected colonies of Spain and the Azores. A definite decline has been reported from the Canary Islands and Madeira, however. Its main causes are predation by humans, cats, dogs, rats and mustelids, while competition with rabbits for breeding holes and disturbance by more and more invading tourism need also to be considered (Tucker & Heath).

Little Shearwater, Puffinus assimilis

This pelagic bird inhabits the Atlantic, Pacific and Indian oceans, being much more numerous in the Southern Hemisphere. The European population inhabits the Canary Islands, the Azores and Madeira. It amounts about 2700-3900 breeding pairs. This species is adversely affected by the introduction of rats on its breeding islands, and the population of the Canary Islands has strongly decreased during the last 20 years.

Balearic Shearwater, Puffinus (puffinus) mauretanicus

This bird has for a long time been considered as a subspecies of the Manx Shearwater (Puffinus puffinus). Today it is considered either a full species (Puffinus mauretanicus) or a subspecies of the Mediterranean Shearwater (Puffinus yelkouan). What be the taxonomy adopted, only the birds breeding on the Balearic Islands are included in the Annex I. This population amounts to 3300-5000 breeding pairs (EBCC Atlas of European Breeding Birds).

White-faced Petrel, Pelagodroma marina

This pelagic bird is breeding on the Salvagens, Madeira and the Canary Islands. Its European population amounts to 16000-20000 breeding pairs and seems quite stable. It is vulnerable, however, since it is located on two islands only (Tucker & Heath).

Storm Petrel, Hydrobates pelagicus

This pelagic bird is breeding on the Atlantic and Mediterranean coasts of Europe and North Africa. It is very hard to estimate its populations, since its colonies are virtually inaccessible, since it moves mainly at night and since there is a large non-breeding population. Nevertheless, the population of the European Union is estimated at 150000 breeding pairs and the total European population at 346000-640000 pairs (EBCC Atlas of European Breeding Birds).

Madeiran Storm-petrel, Oceanodroma castro

This pelagic bird inhabits the temperate and tropical regions of the Atlantic and Pacific oceans. The population of the European Union, breeding on Madeira Islands (Madeira, Desertas and Salvagens), the Azores, Tenerife and the Farilhões off Portugal, amounts to 3700 breeding pairs. Its trends are badly known, but the species is adversely affected by the introduction of rats on its breeding islands and the recent increase in Yellow-legged Gulls (Larus michahelli).

Leach's Storm-petrel, Oceanodroma leucorhoa

This pelagic bird inhabits the northern Atlantic and Pacific oceans where it breeds on isolated islets. The European population is centred on the British Isles and amounts to about 30000 breeding pairs (EBCC Atlas of European Breeding Birds). It winters in the South Atlantic off the South African coast. Being difficult to study, its trends are not known.
