Fulmar (Fulmarus glacialis) Science Article 2 abstract Tussen 1982 en 2001 bleek steeds meer plastic (zwerfvuil) voor te komen in de magen van Noordse stormvogels. Vooral gebruiksplastic nam in het eind jaren negentig zeer sterk toe, waarna zich een afname heeft ingezet (significant over periode 1996-2003). De hoeveelheid industrieel plastic is tussen 1982 en 2003 […]

Sex discrimination and measurement bias in Northern Fulmars Fulmarus glacialis from the Canadian Arctic
Fulmar (Fulmarus glacialis) Science Article 1 abstract The Northern Fulmar Fulmarus glacialis is a seabird in which both sexes have similar plumage, but sexual dimorphism in body size is apparent. We used data from 63 Northern Fulmars collected at Cape Vera, Nunavut, Canada, to develop a discriminant function to predict sex that is based on […]
Olfactory foraging strategies of procellariiform seabirds
European Storm-petrel (Hydrobates pelagicus) Science Article 3 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 […]
Ages of Storm Petrels Hydrobates pelagicus prospecting potential breeding colonies
European Storm-petrel (Hydrobates pelagicus) Science Article 1 abstract Each year, ringers using sound lures mark and recapture immature Storm Petrels Hydrobates pelagicus prospecting potential breeding colonies. Attempts have been made to estimate the size of this population, but a full demographic model has not been possible since the age structure of this population has not […]
Population size estimation and metapopulation relationships of Storm Petrels Hydrobates pelagicus in the Gulf of Biscay.
European Storm-petrel (Hydrobates pelagicus) Science Article 5 abstract Storm Petrels Hydrobates pelagicus are notoriously difficult to census because they nest in burrows and crevices, they visit land at night, and colonies are usually visited by large numbers of itinerant pre-breeding birds (Ratcliffe et al 1998, Insley et al 2002). The Spanish Storm Petrel population has […]
The timing and pattern of moult of flight feathers of European Storm-petrel Hydrobates pelagicus in Atlantic and Mediterranean breeding areas
European Storm-petrel (Hydrobates pelagicus) Science Article 2 abstract Aims: We describe the pattern and timing of moult in European Storm-petrels Hydrobates pelagicus.Location: Benidorm Island (eastern Spain, Mediterranean Iberian coast) and Vizcaya (northern Spain, Atlantic Iberian coast).Methods: Birds were caught with mist-nests set in breeding colonies and the state of flight feathers was scored. Primary, secondary […]
Diet and foraging behaviour of the British Storm Petrel Hydrobates pelagicus in the Bay of Biscay during summer.
European Storm-petrel (Hydrobates pelagicus) Science Article 4 abstract The diet and the foraging behaviour of the British Storm Petrel Hydrobates pelagicus during the breeding period were studied from proventriculus contents obtained from adults belonging to two populations in the Bay of Biscay. The observed prey had various ecological affinities in two main groups. The first […]
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 […]
