THE INFLUENCE OF NEIGHBOURS ON BREEDING SYNCHRONY INCORY’S SHEARWATER CALONECTRIS DIOMEDEA
Corys Shearwater (Calonectris diomedea) Science Article 1 abstract The influence of neighbours on breeding synchrony in Cory’s Shearwater Calonectris diomedea J-L. Mougin, C. Jouanin, M-C. Mougin & F. Roux, Marine Ornithology 29: 51-56 Download article download full text (pdf)
The first two cases of melanism in Cory’s Shearwater Calonectris diomedea
Corys Shearwater (Calonectris diomedea) Science Article 2 abstract Although aberrant colourations occur in a great variety of animal species, their frequency of occurrence is low. Here, we report the first two observations of melanistic Cory’s Shearwaters Calonectris diomedea, in the Azores archipelago and on the Canary Islands. Because dark plumages may be associated with subordinate […]
Olfactory foraging strategies of procellariiform seabirds
Bulwers Petrel (Bulweria bulwerii) Science Article 1 abstract The study of olfactory foraging ability in procellariiform seabirds is now beginning to explore how species aremorphologically and behaviorally adapted to track odor plumes, and to relate these findings to models of odor transport innatural situations. According to the models, odors in atmospheric flow tend to be […]
RESULTS OF SEARCH FOR NESTING BLACK-CAPPED PETRELS (Pterodroma hasitata) IN DOMININCA
Black-capped Petrel (Pterodroma hasitata) Science Article 4 abstract Evidence shows the Black-capped Petrel was abundant in Dominica during the last half of the 19th century (Bent 1922, Lawrence 1878). Studies done in the early 20th century continued to show the bird was seen ‘not infrequently’ off the coast of Dominica in the vicinity of Roseau […]
A Black-capped Petrel Specimen from Florida
Black-capped Petrel (Pterodroma hasitata) Science Article 2 abstract The Black-capped Petrel (Pterodroma hasitata) is a rare bird anywhere in North America (Palmer, 1962). and may exist only in small numbers throughout the world because of habitat alteration Glen E.

A RE-EVALUATION OF THE STATUS OF THE ENDANGEREDBLACK-CAPPED PETREL, PTERODROMA HAS/TATA, IN CUBA
Black-capped Petrel (Pterodroma hasitata) Science Article 1 abstract The Black-capped Petrel, Pterodroma hasitata, is the only extant gadfly petrel known to breed in the West Indies region. Now seriously threatened or endangered, breeding populations are known on only one of the five historically documented breeding islands David S. Lee & Nicasio Vina, ORNITOLOGIA NEOTROPICAL 4:99-101 […]
DISCOVERY OF BREEDING BLACK-CAPPED PETRELS ON HISPANIOLA
Black-capped Petrel (Pterodroma hasitata) Science Article 3 abstract The status of the Black-capped Petrel (Pterodroma hasitata), which formerly bred on several West Indian islands, has been obscure since late in the nineteenth century, when the location of the diminishing breeding colonies was lost to science DAVID B. WINGATE, The Auk, 81: 147-159. April, 1964 Download […]
Modelling demography and extinction risk in the endangered Balearic shearwater
Balearic Shearwater (Puffinus mauretanicus) Science Article 1 abstract Several demographic parameters of Balearic shearwater (Puffinus mauretanicus) were estimated and used to model extinction probabilities for the species, which is an endemic seabird confined to a Mediterranean archipelago. Adult survival was analyzed through capture-recapture models at two colonies free of adult predators during 1997-2002. Extinction probabilities […]
WINTERING DISTRIBUTION OF THE BALEARIC SHEARWATER (PUFFINUS YELKOUAN MAURETANICUS, Lowe 1921) OFF THE NORTHEASTERN COAST OF SPAIN
Balearic Shearwater (Puffinus mauretanicus) Science Article 2 abstract The taxonomic status of the Mediterranean Shearwater (Pufimuss yelkouan) is still under discussion (Altaba, 1993; Vittery,1994). The species is already clearly separated on from the Manx Shearwater. Ricard GUTIERREZ and Jordi FIGUEROLA, Ardeola(42)2, 1995 161-166 Download article download full text (pdf)
