In 1902: The breeding-habits of the Fieldfare are only to be observed in the north and east of Europe ; for in every other part of the continent the bird is scarcely ever known as other than a winter visitant. It is fond of the neighbourhood of cultivated land, birch-woods, or those wherein birch and …

Wood Nuthatch (Sitta europaea) Science Article 3 abstract Bills of juvenile Nuthatches continue to increase in size (length and depth) for up to three months after fledging. Bills of individual full-grown birds increase in length from April to October with a temporary drop in June, and decrease throughout the winter season. Bill depth increases from …

Wood Nuthatch (Sitta europaea) Science Article 1 abstract We expected to find a clearly manifested mate guarding behaviour in males of Sitta europaea as males of this socially monogamous species participate extensively in parental care. We recorded behaviour of nuthatches during one breeding season in primaeval stands of the Biatowie

Wood Nuthatch (Sitta europaea) Science Article 2 abstract We choose the European Nuthatch (Sitta europaea), an extremely socially monogamous passerine species, to investigate the breeding biology and frequency of extra-pair activities of females. Breeding individuals live in strong pair bonds for their total life and defend their territory all year round. As a consequence of …

Starling (Sturnus vulgaris) Science Article 3 abstract Finnish starling populations have declined, a phenomenon first noted towards the end of the 1970s. Here we use national ringing totals to estimate changes in the starling population. However, the numbers ringed depend not only on the population size but also on yearly variations in ringing activities. Thus, …

Starling (Sturnus vulgaris) Science Article 5 abstract Practically all animals must find food while avoiding predators. An individual’s perception of predation risk may depend on manyfactors, such as distance to refuge and group size, but it is unclear whether individuals respond to different factors in a similarmanner. We tested whether flocks of foraging starlings responded …

Starling (Sturnus vulgaris) Science Article 2 abstract A long-term study of the breeding success of an increasing population of great spotted woodpeckers in southern England has shown that nest survival has increased dramatically and the nesting season advanced over the last 20 years. Nest site interference by starlings was frequently observed in the early years …

Starling (Sturnus vulgaris) Science Article 4 abstract The mechanics of avian take-off are central to hypotheses about flight evolution, but have not been quantified in terms of whole-body movements for any species. In this study, I use a combination of high-speed video analysis and force plate recording to measure the kinematics and mechanics of ground …

Starling (Sturnus vulgaris) Science Article 15 abstract Intraspecific brood parasitism in the Starling Sturnus vulgaris was studied inCentralNorway. Before clutch initiation, Starlings recognise and remove parasitic conspecific eggs but are usually not able to do so after they have started to lay eggs themselves. The frequency of natural parasitism was 10%. Since ejection of the …

Starling (Sturnus vulgaris) Science Article 9 abstract Although the starling has the capacity for explosive population growth, its population in Britain has declined bytwo-thirds over the last 40 years. Here we summarize a major study (Crick et al., 2002) which investigates the reasons for this.The starling is commonest in urban and farmland habitats, though density …
