Colonial and associated with coot (fulica atra) nesting in great crested grebe (podiceps cristatus), comparison of three lakes

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.
