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 […]
