Rarest birds of the World: chatham Island Shag (Phalacrocorax onslowi)

This species occupies a very area on the Chatham Islands, New Zealand. The past 10 years, surveys indicate that the species is in decline. In 2011 the population was estimated to be about 1000 individuals. The breeding colonies suffered much from agricultural activities and feral mammals. These colonial ground breeding species trample their eggs while […]

Pseudo-eggs of brown sula leucogaster andblue-footed s. nebouxii boobies in the gulf of california, mexico

Brown Booby (Sula leucogaster) Science Article 4 abstract Pseudo-eggs, foreign round objects, notably eggs of other speciesor pebbles, are common in some ground-nesting species, and havebeen reported especially in larids (Sugden 1947, Twomey 1948,Coulter 1980, Conover 1985). As many as 10% of Ring-billedGull Larus delawarensis nests in Washington, USA includedpseudo-eggs (Conover 1985). The nests of […]

Dna fingerprinting and parentage in masked (sula dactylatra) and brown (s. leucogaster) boobies

Brown Booby (Sula leucogaster) Science Article 10 abstract Masked Booby (Sula dactylatra) and Brown Booby (S. leucogaster) are pantropical seabirds. These species are socially monogamous. Thus, males and females have a high investment in parental care. In this work, field observations and DNA fingerprinting were applied to investigate the breeding system of both species. Two […]

Molecular Phylogeny of Babesia poelea From Brown Boobies (Sula leucogaster) FromJohnston Atoll, Central Pacific

Brown Booby (Sula leucogaster) Science Article 2 abstract The phylogenetic relationship of avian Babesia with other piroplasms remains unclear, mainly because of a lack of objective criteria such as molecular phylogenetics. In this study, our objective was to sequence the entire 18S, ITS-1, 5.8S, and ITS-2 regions of the rRNA gene and partial B-tubulin gene […]
