Heritability of nestling growth in cross-fostered European Starlings Sturnus vulgaris.

Pollutants affect development in nestling starlings Sturnus vulgaris

Body Mass, Composition, and Survival of Nestling and Fledgling Starlings (sturnus Vulgaris) at Belmont, New Zealand

Earlier studies of the starling (Sturnus vulgaris) population at Belmont, Lower Hutt, New Zealand, showed that nest productivity was low compared with other populations in New Zealand and elsewhere. Therefore, we investigated possible trade-offs between offspring number and quality (as measured by body mass and composition). We also compared these measures of offspring condition with preand pos...

Nest composition and yolk hormones: do female European starlings adjust yolk androgens to nest quality?

The nest is a key element of avian reproductive fitness. It provides the developmental environment for the embryo and nestling thereby affecting their quality and survival. Nests are often constructed by the male and nest quality, elaboration, and ornamentation vary among males in a species. Therefore, male nest-building behaviour is likely under sexual selection and females may use male nest-b...

Early life disadvantage strengthens flight performance trade-offs in European starlings, Sturnus vulgaris

Developmental stress has been shown to affect adult flight performance in birds, with both negative and positive effects reported in the literature. Previous studies have used developmental manipulations that had substantial effects on patterns of growth. They have also examined mean levels of flight performance per individual, rather than investigating how developmental stress might alter trad...

Brood size moderates associations between relative size, telomere length, and immune development in European starling nestlings

For young birds in a nest, body size may have implications for other aspects of development such as telomere length and immune function. However, it is possible to predict associations in either direction. On the one hand, there may be trade-offs between growth and telomere maintenance, and growth and investment in immune function, suggesting there will be negative correlations. On the other ha...
