Great Crested Grebe (Podiceps cristatus) Science Article 5
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 in breeding habitat characteristics and were used as nominal variables. The Chi-square analysis revealed significant relations between the rates of colonial and associated nesting on the one hand and the lake and the year of breeding on the other.
