The number of bird species listed as Critically Endangered has reached an all-time high with the release of this year’s Red List for birds by BirdLife International. White-winged Flufftail Sarothrura ayresi, a secretive and unobtrusive sub-Saharan bird, is the latest species to join the growing list of those on the very edge of extinction. Destruction […]

Where two oceans meet: distribution and offshore interactions of great-winged petrels Pterodroma macroptera and Leach’s storm petrels Oceanodroma leucorhoa off southern Africa

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. […]

Seabird geographic variation: similarity among populations of leach’s storm-petrel

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 […]

The cape petrel (Daption capense) around Mawson Station, East Antarctica: new breeding localities and population counts

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).

The endemic Mediterranean yelkouan shearwaterPuffinus yelkouan: distribution, threats and a pleafor more data

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 […]

How can the Yelkouan shearwater survive feral cat predation?A meta-population structure as a solution?

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 […]
