Sooty tern nesting success as a function of nest location, density and vegetationtype in a neotropical atoll

Sooty Tern (Sterna fuscata) Science Article 10 abstract Nest density and reproductive success are used as indicators of habitat preference by animals. However, isolated treatment of these factors may be misleading. We studied habitat selection by Sooty Terns (Sterna fuscata) in an atoll in Brazil, composed of Farol and Cemiterio Islands. The islands were used […]

New Zealand-banded Sooty Tern (Sterna fuscata) breeds in the Seychelles

Sooty Tern (Sterna fuscata) Science Article 3 abstract Over 14 600 Sooty Terns (Sterna fuscata serrata) have been banded underthe New Zealand National Banding Scheme. The great majority of themwas banded between 1961 and 1969 by Civil Aviation staff stationed on RaoulIsland in the Kermadec group (29O 15’S, 177O 55′ W) and during theOrnithological Society […]

Colony Visitation Behavior And Breeding Ages Of Sooty Terns (Sterna Fuscata)

Sooty Tern (Sterna fuscata) Science Article 7 abstract The apparent regulation of population size in seabirds has been a topic of recent research by several ornithologists (e.g. Ashmole, 1963b; Harris, 1969a, b, c; Nelson, 1965, 1966, 1969a, b; Rowan 1965; and Lack, 1968). These authors theorize that major limiting factors are either availability of food […]

Challenges and prospects of population genetic studies in terns(Charadriiformes, Aves)

Sooty Tern (Sterna fuscata) Science Article 8 abstract Little information is available about the population structure of communally nesting terns (Sternidae) and skimmers(Rynchopidae) throughout the world. In order to fill this gap, a survey of molecular markers was carried out for sixspecies of terns (Anous stolidus, Sterna hirundinacea, S. fuscata, S. superciliaris, Thalasseus maximus andPhaetusa […]

Growth and energetics of chicks of the Sooty Tern (Sterna fuscata) and Common Tern (S. hirundo)

Sooty Tern (Sterna fuscata) Science Article 1 abstract We measured the energy budgets of chicks of the Common Tern (Sterna hitundo) on Great Gull Island, New York and of the Sooty Tern (S. fuscata) on the Dry Tortugas, Florida. The respiratory energy requirement was determined by measuring oxygen consumption in a closed system. We calculated […]

Climatological Effects On The Breeding Of Terns

Sooty Tern (Sterna fuscata) Science Article 6 abstract The physical circulation in the Western Indian Ocean controls the supply of nutrients, and this, combined with the stability of the surface layer and the availability of sunlight controls the primary production. In this note, we review two papers’ findings on how the physical conditions ultimately impact […]

Sexing sooty terns on Ascension Island frommorphometricmeasurements

Sooty Tern (Sterna fuscata) Science Article 9 abstract Sooty terns Onychoprion fuscata are one of the most abundant seabirds but breeding populations in many colonies have diminished. Rapid sexing of sooty terns in the field could be crucial in advancing our understanding of their reproductive biology, and in promoting conservation. However, sooty tern males and […]

Egg specific gravity and incubation in the Sooty Tern and Brown Noddy.

Sooty Tern (Sterna fuscata) Science Article 11 abstract Flotation characteristics of birds’ eggs are commonly used to estimate their age. Schreiber (1970) and Hays and LeCroy (1971) have recently attempted to quantify the relationship between the appearance (degree of emergence and position) larid eggs placed in water and the age of the eggs. Westerskov (1950) […]

Oxygen Consumption and Organ Growth in Sooty Tern (Sterna Fuscata) Embryos

Sooty Tern (Sterna fuscata) Science Article 2 abstract A previous report (Zhang and Whittow 1992) described the patterns of embryonic oxygen consumption and organ growth in the Wedge-tailed Shearwater (Puffinusp acificusI)n. the presents tudy, similar data were obtained for the Sooty Tern. There are some similaritiesb etween the eggso f the two species. The sequence […]

An inventory of Sooty Terns (Sterna fuscata) in the western Indian Oceanwith special reference to threats and trends

Sooty Tern (Sterna fuscata) Science Article 4 abstract The western Indian Ocean supports over 6 200 000 pairs of Sooty Terns, some in very large colonies. During the past twocenturies colonies have exhibited increase, stability, decline and extinction. The main drivers of these trends have beenhabitat change and unregulated human exploitation, especially of adults; introduced […]
