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. Particular lakes and years were considered as integrators of between-lake and between-year differences in breeding […]

Moorhen gallinula chloropus females lay eggs of different size and b-carotene content

Common Gallinule (Gallinula chloropus) Science Article 5 abstract In birds, carotenoids deposited in the eggs can influence the progeny?s prospects of survival. As a potentially limiting resource, carotenoids should be allocated optimally by the mother during egg production. The Moorhen Gallinula chloropus produces large clutches. We tested if females differ in their allocation of macronutrients […]
