Roseate Terns Sterna dougallii on the southeast coast of South Africa: information on moult and migratory status

Autor: Maëlle Connan, Anthony J. Tree, PA Whittington

Publikováno v: Ostrich: Journal of African Ornithology; Vol 90, No 4 (2019); 303–313

Determining the migratory status of seabird populations is crucial for addressing conservation concerns. The Roseate Tern Sterna dougallii is considered endangered in South Africa in view of its small breeding population and the threats to eggs and c

Age‐specific variation in relationship between moult and pre‐migratory fuelling in Wood Sandpipers Tringa glareola in southern Africa

Autor: Anthony J. Tree, Les G. Underhill, Marc S. Burman, Magdalena Remisiewicz

Publikováno v: Ibis. 159:91-102

Trans-equatorial avian migrants tend to breed, moult and migrate – the main energy-requiring events in their lifecycle – at different times. Little is known about the relationship between wing moult and pre-migratory fuelling in waders on their n

The subspecies of Antarctic Terns (Sterna vittata) wintering on the South African coast: evidence from morphology, genetics and stable isotopes

Autor: Christopher D. McQuaid, Anthony J. Tree, Maëlle Connan, Peter R. Teske, PA Whittington

Publikováno v: Emu - Austral Ornithology. 115:223-236

Five to seven subspecies of Antarctic Tern (Sterna vittata) are recognised, with at least three (S. v. vittata, S. v. tristanensis and S. v. sanctipauli) wintering in South Africa. Morphological characters used to define these subspecies are not perf

Geographical Patterns in Primary Moult and Body Mass of GreenshankTringa nebulariain Southern Africa

Autor: Magdalena Remisiewicz, Anthony J. Tree, Les G. Underhill, Jarosław K. Nowakowski

Publikováno v: Ardea. 102:31-46

Greenshanks Tringa nebularia show various patterns of primary moult in the northern hemisphere, but farther south moult patterns are known only fragmentarily. We Identified geographical patterns in primary moult and pre-migratory fattening of Greensh

The status of the Damara Tern in the Eastern Cape, South Africa §

Autor: PA Whittington, Anthony J. Tree, Elizabeth G Watkins, Maëlle Connan

Publikováno v: Ostrich: Journal of African Ornithology; Vol 86, No 1-2 (2015); 65–73

The Eastern Cape population of the Damara Tern Sternula balaenarum was estimated to be 25–29 pairs in the 2008/09 and 2009/10 breeding seasons. The population appears to be stable and has probably increased slightly since the early 1990s. An eastwa

Rapid or slow moult? The choice of a primary moult strategy by immature Wood Sandpipers Tringa glareola in southern Africa

Autor: P. Barry Taylor, Les G. Underhill, Magdalena Remisiewicz, Anthony J. Tree

Publikováno v: Journal of Ornithology. 151:429-441

Immature migrant waders have more complex patterns of primary moult than adults, but these have been described only fragmentarily. The Wood Sandpiper Tringa glareola breeds in the taiga region of the Palearctic and part of the population migrates to

Extended Primary Moult as an Adaptation of Adult Wood SandpipersTringa glareolato Their Freshwater Habitats in Southern Africa

Autor: Anna Gustowska, Anthony J. Tree, Les G. Underhill, P. Barry Taylor, Magdalena Remisiewicz

Publikováno v: Ardea. 97:271-280

Migrant waders using freshwater habitats are hypothesized to have slower primary moult than waders using coastal habitats. We chose the Wood Sandpiper Tringa glareola as a representative species using the freshwater habitats and compare its moult pat

Recent distributional changes of seabirds in South Africa: is climate having an impact?

Autor: Rjm Crawford, PA Whittington, KJ Roxburg, Anthony J. Tree, AP Martin, L Upfold, J Visagie, B. M. Dyer

Publikováno v: African Journal of Marine Science. 30:189-193

There have been recent changes in the distributions of several seabirds in South Africa. In the mid-1990s, breeding of Leach's storm petrel Oceanodroma leucorhoa was recorded in the Western Cape, the first record for the Southern Hemisphere. There wa
