on the large basins in the Romanian part <strong>of</strong> Dobrudja (Puscariu, 1968). In the past<br />

nests were found on Lake Serbanul by Braila, near Chilia Veche, near Lake Sinoe and<br />

to the south <strong>of</strong> Gridul Lupitor (Lintia, 1954). According to Zubarowskii (1977), the<br />

White-tailed Eagle was nesting in Odessa and the districts <strong>of</strong> Hersonska and<br />

Zaporojka. Nests were found on the lower courses <strong>of</strong> the rivers Dnestar and Dniepr.<br />

Several pairs were nesting regularly in the southern rocky part <strong>of</strong> the Crimean<br />

mountains and in the high-stemmed woods <strong>of</strong> the Crimean reserve (Kostin, 1983); 7-8<br />

pairs <strong>of</strong> White-tailed Eagles nest in the lower course <strong>of</strong> the river Don (Golushin,<br />

1983). Two pairs breed in the lower course <strong>of</strong> the river Kuban (Zabalotnii & Hohlov,<br />

1995). During the breeding <strong>sea</strong>son, one White-tailed Eagle was also observed in the<br />

Ahtanizolski firth (Tilba et ah, 1990). Nesting areas along the Georgian coast are<br />

unknown. In the northern regions <strong>of</strong> Turkey, White-tailed eagles nest to the west and<br />

east <strong>of</strong> Istanbul and mainly in the river Kizilirmak delta (OST Bird Report, 1975;<br />

Cramp & Simmons, 1980). During migrations and especially in winter, the basins<br />

along the whole Black Sea coast become important habitats for White-tailed eagles<br />

from northern populations (from the Scandinavian peninsula and the European part <strong>of</strong><br />

Russia).<br />

Habitat type, Critical habitats, Limiting factors. In the breeding <strong>sea</strong>son as well as<br />

during migrations and overwintering, birds keep close to wooden and rocky areas<br />

near the <strong>sea</strong>shore or lakes and rivers. They are attracted by clear water basins full <strong>of</strong><br />

fish and water birds.<br />

<strong>Biology</strong>. A monogamous bird which starts breeding after its fourth year. Pairs build<br />

nests on high trees or on rocks at a distance <strong>of</strong> several km. from each other. They lay<br />

3-4 eggs in February - March, brood more than one month, young remain in the nest<br />

2-3 months and afterwards stay one more month in the area, where parents continue to<br />

feed them. Omnivorous. Beside fish and water birds it also feeds on mammals, rats,<br />

rabbits, foxes, wandering dogs and cats, and tortoises. It also scavenges. In winter it<br />

stays close to concentrations <strong>of</strong> water birds (geese, ducks, coots, herons, grebes, gulls<br />
