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 […]
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 […]
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) […]
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 […]
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 […]
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 […]
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 […]
Influence of date and body mass at fledging on long-term survival of sooty terns sterna fuscata
Sooty Tern (Sterna fuscata) Science Article 5 abstract The Sooty Tern Sterna fuscata is a pan-tropical seabird that nests typically on isolated oceanic islands. Sooty Terns nest always on the ground, generally amongst sparse herb vegetation and often in large dense colonies, sometimes numbering hundreds of thousands of pairs (Gochfeld & Burger 1996, Schreiber at […]
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 […]
Notes on the Biology of Chapman’s SwiftChaetura chapmani (Aves, Apodidae)
Sicks Swift (Chaetura meridionalis) Science Article 2 abstract In the rolling terrain of the central hills of Trinidad, Frank M. Chapman collected a large series of swifts, among which were eight specimens representing a previously unknown species. These specimens, taken between March 15 and March 27, 1894, near the town of Caparo, Caroni County, were […]
