Great Crested Grebe (Podiceps cristatus) Science Article 5 abstract Nesting of the Great Crested Grebe in loose colonies and in close association with the Coot was investigated in Lakes Meteliai and Obelija in 1983-?1986 and 1999 and in Lake paltytis in 1984-?1986. Particular lakes and years were considered as integrators of between-lake and between-year differences […]

Great Crested Grebe (Podiceps cristatus) Science Article 1 abstract Between 1993 and 2000, breeding success of Great Crested Grebe Podiceps cristatus was monitored at two fishpond localities, Vrbje in central and Race in north-eastern Slovenia. During the study 50 and 23 nests with eggs were found, respectively. On average, 1.3 chicks per territorial pair survived […]

Great Crested Grebe (Podiceps cristatus) Science Article 3 abstract 221 recovery data of European Great Crested Grebes were analysed. Great Crested Grebes migrate SE to winter mainly in southern parts of the (former) Soviet Union or Turkey (Fennoscandian birds), or in the central European lakes (individuals from northwestern Europe). A second wintering area is found […]

Great Crested Grebe (Podiceps cristatus) Science Article 2 abstract On a fish-farm in The Netherlands Great Crested Grebe breeding pairs arrived in two distinct periods. We suggest this pattern reflects differences in migratory behaviour, whereby late birds are migrants. In early arriving grebes clutch size decreased with an increasing pre-laying period, whereas in late grebes […]

Great Crested Grebe (Podiceps cristatus) Science Article 4 abstract Food intake rate during the nonbreeding season of Great Crested Grebes Podiceps cristatus was estimated by reconstructing the stomach content of drowned birds from recognizable remains of the fish prey. Food intake by individual birds since the ejection of the last pellet (the accumulated prey mass) […]
