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

Coot (Fulica atra) Science Article 6 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.
