The snowy albatross (Diomedea exulans), also known as the wandering albatross, is one of the largest flying birds, boasting the longest wingspan of any living species, reaching up to 3.7 meters (12.1 feet). A true oceanic wanderer, it inhabits the Southern Ocean, where it spends most of its life soaring effortlessly over vast distances. Highly […]
Mother-Cary’s chicken or Leach’s petrel is well known to the Indians of this region who frequently make protracted voyages in their frail canoes miles from the coast-line among the islands lying off the mouth of the Penobscot and Kennebec rivers. These little birds are correctly named from their habit of obtaining nourishment by scooping animal […]
Help science to study and protect the vulnerable. Contribute your data to the cause. Graduate student seeks data on precise breeding islands of Yelkouan Shearwaters and their threats on those islands: I am looking for survey or observation years from islands (if available) where breeding is occurring or occurred in the past (if it is […]
Leachs Storm-Petrel (Oceanodroma leucorhoa) Science Article 1 abstract During seabird surveys off southern Africa, great-winged petrel Pterodroma macroptera and Leach’s storm petrel Oceanodroma leucorhoa were widespread and relatively common. Similar aerial displays, frequent (social) interactions, a tendency to ‘huddle’ in tight (mixed) gatherings and interactions during foraging inspired a study of their behaviour and distribution. […]
Leachs Storm-Petrel (Oceanodroma leucorhoa) Science Article 2 abstract We assessed geographic variation in 13 locality samples of Leach’s Storm-Petrel (Oceanodroma leucorhoa), 12 from the Pacific coast and I from the Atlantic coast ofNorth America. Nine phenetic characters were used with canonical variates analysis to determine similarity among samples. Regression of phenetic distance on geographic distancemeasured […]
Cape Petrel (Daption capense) Science Article 1 abstract The cape petrel Daption capense is a widespread Southern Ocean procellarid, breeding around the Antarctic continent and on many sub-Antarctic islands (Marchant and Higgins 1990). Around Mawson, a permanently manned Australian station in East Antarctica DAVID WILSON, Notornis, 2009, Vol. 56: 162-164 Download article download full text […]
Yelkouan Shearwater (Puffinus yelkouan) Science Article 1 abstract The endemic Mediterranean yelkouan shearwater Puffinus yelkouan, elevated to the rank of species in 2002, is poorly monitored and studied. Despite this lack of data and the susceptibility of closely related species to threats at breeding sites and foraging areas, the yelkouan shearwater is currently considered to […]
Yelkouan Shearwater (Puffinus yelkouan) Science Article 3 abstract The Yelkouan shearwater, Puffinus yelkouan, is an endangered Mediterranean endemic species of burrowing petrel threatened by feral cats. The life-history parameters of a small population of Yelkouan shearwaters on the Mediterranean island, Port-Cros, were studied inconjunction with the diet of feral cats, to examine the birds’ vulnerability […]
Yelkouan Shearwater (Puffinus yelkouan) Science Article 2 abstract Over the past six months, the EU LIFE Yelkouan Shearwater Project has been undertaking fieldwork to fitelectronic devices to the Yelkouan Shearwaters to monitor their movements at sea. The tags are the latest intechnology for seabird tracking. This is the first time that such extensive research on […]
Wilsons Storm-petrel (Oceanites oceanicus) Science Article 5 abstract Wilson’s storm petrel (Oceanites oceanicus) characteristically feeds by’ hovering’ over the water surface, but its technique for this is unlike that ofother flying vertebrates. The kinematics and aerodynamics of this ‘ hovering’flight were investigated to determine the possible sources of lift PHILIP C. WITHERS, J. exp. Biol. […]
