Siberian Stonechat (Saxicola maura) Science Article 2 abstract It has been hypothesized that organisms living at different latitudes or in different environments adjust their metabolic activity to the prevailing conditions. However, do differences in energy turnover simply represent a phenotypic adaptation to the local environment, or are they genetically based? Martin Wikelski, Proc. R. Soc. […]

Gonadal status upon spring arrival in long-distance and short-distancemigrating stonechats ( Saxicola torquata)
Siberian Stonechat (Saxicola maura) Science Article 1 abstract Long-distance migration is often associated with relatively short breeding seasons and a start of reproductive activities shortly after arrival. The full activation of the reproductive system from the regressed state takes, however, several weeks and must, therefore, be initiated in the winter quarters or during spring migration. […]
Environmental factors determine numbers of overwintering European Stonechats Saxicola rubicola: A long-term study.
European Stonechat (Saxicola rubicola) Science Article 3 abstract In this study the relationship between the number of European Stonechats Saxicola rubicola at a winter site in Israel and the local rainfall, air temperature, and arthropod abundance was examined. In some years population size declined to about one third of the initial size, while in others […]
Timing of molt as a buffer in the avian annual cycle
European Stonechat (Saxicola rubicola) Science Article 1 abstract Birds in seasonal environments must time stages in their annual life cycles precisely. While the fitness costs ofmistimed reproduction and migration are widely recognized, molt has been viewed as a more flexible element. Birds modify thetiming of molt in various ways to keep to overall timetables, but […]

Site fidelity in the Canary Islands stonechat Saxicoladacotiae in relation to spatial and temporalpatterns of habitat suitability
Canary Islands Stonechat (Saxicola dacotiae) Science Article 2 abstract We investigate the degree of territory faithfulness of the Canary Islands stonechat Saxicola dacotiae, an endemic bird species of the semi-arid island of Fuerteventura (Canary Islands, Spain), and the spatial and temporal variability of habitat traits related to its breeding success over its whole distribution range. […]
Divorce in the Canary Islands Stonechat (Saxicola dacotiae)
Canary Islands Stonechat (Saxicola dacotiae) Science Article 1 abstract I report the first case of divorce for the Canary Islands Stonechat (Saxicola dacotiae), anendemic bird species of the semiarid island of Fuerteventura (Canary Islands, Spain). I studied 72 pairs during three breeding seasons (2000-2001, 2001-2002, and 2002-2003). Juan Carlos Illera, Wilson Bulletin 117(3):317-319, 2005 Download […]
