ABSTRACT.— The Atlantic Lesser Frigatebird (Fregata trinitatis) is elevated to a separate species from Fregata ariel of the Indo-Pacific based on plumage differences and greater robustness of the rostrum and wing bones. The species now occurs only on the remote South Atlantic island of Trindade (South Trinidad) over 1,100 km east of mainland Brazil, although fossils establish that it once also occurred at St. Helena. Fregata trinitatis no longer breeds on the main island of Trindade and is only…

A Great Frigatebird Fregata minor at Fernando de Noronha archipelago, equatorial Atlantic Ocean
Summary. We report a documented record of a Great Frigatebird Fregata minor at Fernando de Noronha, 360 km off the coast of northeast Brazil in the equatorial Atlantic. We presume that the bird at

TLDR
Differences in the composition and relative abundance of species between the deposits of different age indicate that the marine environment at St. Helena became progressively more tropical late in the Pleistocene, which resulted in great decreases in, or even extinction of, some of the species of Procellariiformes.
Long-term isolation of a highly mobile seabird on the Galapagos
TLDR
Signs of extensive gene flow are found over most of the range of magnificent frigatebirds, even across the Isthmus of Panama, which is a major barrier to gene flow in other tropical seabirds.
A Review of Feral Cat Eradication on Islands
Abstract:  Feral cats are directly responsible for a large percentage of global extinctions, particularly on islands. We reviewed feral cat eradication programs with the intent of providing
Postbreeding Movements of Frigatebirds Tracked with Satellite Telemetry
Abstract Using satellite telemetry, we studied the postbreeding movements of Great (Fregata minor) and Magnificent Frigatebirds (F. magnificens) at two breeding colonies in the Indian and Atlantic
DISTRIBUTION AND DISPERSAL OF CENTRAL PACIFIC LESSER FRIGATEBIRDS ‘FREGATA ARZEL*
Summary During the period from March 1963 to July 1965 the Pacific Ocean Biological Survey Program made an extensive study of the islands of the Central Pacific in the area bounded by 10°N.,180°
The eradication of feral cats from Ascension Island and its subsequent recolonization by seabirds
TLDR
Breeding success of seabirds at Ascension was low compared to that of conspecifics elsewhere, and the roles of food availability, inexperience of parent birds and black rat predation in causing this warrant further investigation.
Eradication of feral goats from small islands
Concern about the effects of feral goats on Aldabra atoll—a UNESCO World Heritage Site—led to a search for solutions. The search highlighted the inaccessibility of information on feral goat
Geologic Youth of Gal�pagos Islands Confirmed by Marine Stratigraphy and Paleontology
TLDR
Six distinctive types of fossiliferous marine deposits occur on the Gal�dpagos Islands that provide evidence for the age of emergence of the islands above sea level and hence a maximum age for the islands' terrestrial biota, indicating that the islands emerged from the sea relatively recently.
Review of impacts of the introduced house mouse on islands in the Southern Ocean: are mice equivalent to rats?
TLDR
Mouse impacts on Southern Ocean islands’ plants, invertebrates, land birds and seabirds are reviewed, and the kinds of effects that can be expected elsewhere are described.
