Breeding of White-tailed Tropicbirds (Phaethon lepturus) in the western South Atlantic.

Basic information on natural history is crucial for assessing the viability of populations, but is often lacking for many species of conservation concern. One such species is the White-tailed Tropicbird, Phaethon lepturus (Mathews, 1915). Here, we address this shortfall by providing detailed information on reproductive biology, distribution and threats on the Fernando de Noronha archipelago, Br...

Foraging behavior and at-sea distribution of White-Tailed Tropicbirds in tropical ocean.

We used miniaturized GPS loggers and site observations to access foraging patterns and nest behaviour of the White-tailed Tropicbird Phaethon lepturus (WTTB), an endangered species at its South Atlantic breeding colony. Dual foraging pattern was observed with alternation between long and short foraging trips. Birds responsible for nest attendance engaged in short foraging trips with mean distan...

Trophic ecology of marine birds and pelagic fishes from Reunion Island as determined by stable isotope analysis

Stable nitrogen and carbon isotopes were used to investigate trophic ecology in tropical marine bird and fish communities from Reunion Island, western Indian Ocean. Firstly, isotope signatures in the liver of Barau's petrels Pterodroma baraui, Audubon's shearwaters Puffinus lherminieri bailloni, and white-tailed tropicbirds Phaethon lepturus were used to compare their trophic levels and determi...

Brainworm, Parelaphostrongylus Tenuis, in White-tailed Deer (odocoileus Virginianus) of Eastern South Dakota: Implications for Western South Dakota

Diseases and parasites are important mortality factors affecting cervid populations. Meningeal worm (Parelaphostrongylus tenuis) is a nematode parasite found in white-tailed deer (Odocoileus virginianus) populations throughout eastern North America. To determine the distribution of meningeal worm in South Dakota, heads of hunter harvested deer were examined for P. tenuis from 1997-1999. A total...
