and others) and feeds on ill, weak or frozen birds. By the <strong>sea</strong>shore it picks up<br />

carcasses <strong>of</strong> dolphins, fish, and birds.<br />

Population trends. A common nesting species along the coasts <strong>of</strong> theBlack and the<br />

Sea <strong>of</strong> Azov and along the valleys <strong>of</strong> the big rivers emptying into these <strong>sea</strong>s in the<br />

past. There was a major decline in the population during 1960-1965. After that, the<br />

number slowly increased again. This was a result <strong>of</strong> the successful breeding and<br />

resettlement <strong>of</strong> the species in Central Europe (Hlorig, 1986), the huge increase <strong>of</strong> the<br />

population in Germany, Poland and Czechoslovakia. From the Danube, the White-<br />

tailed Eagle resettled its previous habitats along the Black Sea. The feeding <strong>of</strong> birds<br />

in Scandinavia, the decrease environmental pollution and the decline in hunting in<br />

Eastern Europe during the last 10th years has also helped . Currently, about 30 pairs<br />

breed along the coasts <strong>of</strong> the Black and the Sea <strong>of</strong> Azov.<br />

Threats. Threats include pollution <strong>of</strong> water basins with different kinds <strong>of</strong> poisons,<br />

the drainage <strong>of</strong> marshes, the cutting down <strong>of</strong> woods and the tourist invasion along the<br />

<strong>sea</strong>shore, the use <strong>of</strong> poisonous baits and traps for wolves and foxes, the meaningless<br />

shooting <strong>of</strong> birds and the destruction <strong>of</strong> their nests. Among the enemies <strong>of</strong> the<br />

Haliaeetus albicilla are Falco cherrug and large colonies <strong>of</strong> ants, which sometimes<br />

force the eagles to leave their nests.<br />

Conservation measures taken. The species is "world endange<strong>red</strong>" and is listed in<br />

Appendix II <strong>of</strong> the Washington Convention. It is protected by law in many European<br />

countries, including in the Black Sea region (Bulgaria, Ukraine and Russia). Many <strong>of</strong><br />

its habitats along the <strong>sea</strong>shores <strong>of</strong> the Black Sea and the Sea <strong>of</strong> Azov are protected<br />

wetlands <strong>of</strong> international importance (National Park Strandja, the deltas <strong>of</strong> the rivers<br />

Danube, Dnestar, Dnepar, the Black Sea reserve, the islands <strong>of</strong> Lebiajie, the river<br />

Kizilirmak delta and others).<br />

Conservation measures proposed. Ban pollution with poisons and industrial waste.<br />

Promote preservation <strong>of</strong> woods, restrict <strong>of</strong> hotel building and tourist invasion <strong>of</strong><br />

habitats along the <strong>sea</strong>shore. Protective propaganda among the human population,<br />

especially among hunters.<br />
