Morphology and Ornamentation in Male MagnificentFrigatebirds: Variation with Age Classand Mating Status
Magnificent Frigatebird (Fregata magnificens) Science Article 3 abstract Male magnificent frigatebird (Fregata magnificens) ornamentationincludes bright iridescent plumage and a red inflatablegular pouch. These signals are displayed during courtship, alongwith a drumming sound produced through specialized beak clackingsresonating in the gular pouch. The extent of white in theplumage identifies three age classes of nonjuvenile male. Here […]

Effects of distance to wintering area on arrival date and breeding performance in Great Cormorants Phalacrocorax carbo
Great Cormorant (Phalacrocorax carbo) Science Article 33 abstract Great Cormorants Phalacrocorax carbo sinensis breeding in the same colony often vary markedly in where they winter and in their date of arrival. The main aim of this study was to explore whether date of arrival, fledgling production and lifetime reproductive success were related to the distance […]
Impact of contaminants on the breeding success of the Cormorant Phalacrocorax carbo sinensis in The Netherlands.
Great Cormorant (Phalacrocorax carbo) Science Article 12 abstract In The Netherlands Cormorants reached a minimum number of breeding pairs in the mid-1960s. Since the end of the 1970s the population is increasing again, and many new and rapidly expanding colonies have been settled. However, in a colony in Dordtse Biesbosch, situated in the centre of […]
