Occurence and transmission of Toxoplasma gondii in European starlings (Sturnus vulgaris) of northern California
This research was performed to determine; (1) the prevalence of Toxoplasma antibodies among starlings in Northern California, (2) if such starlings can transmit the disease, and (3) if tissues from seropositive starlings contain encysted forms of T. gondii.

Genomics and ecology of rapid adaptation: the expansion and evolution of the invasive common myna (<i>Acridotheres tristis</i>) and common starling (<i>Sturnus vulgaris</i>) in New Zealand
… tristis</i>) and the common starling (<i>Sturnus vulgaris</i>), members of the Sturnidae family, are two of the most invasive bird species in the world and are invasive in New Zealand. This thesis aims to evaluate the evolution of the two species following introduction, with the common …

Utilization of natural nest sites by Eastern Bluebirds in southwestern Virginia
… demonstration display sites, and Starling (<i>Sturnus vulgaris</i>) fencepost nest cavities, using discriminant function analysis. Four nest cavities used by bluebirds in 1976 were no longer available in 1977 due to the replacement of fenceposts and tree limb breakage. No new cavities in …

Are there self-imposed group foraging costs in the nutmeg mannikin (Lonchura punctulata)?
… aggression). Recent work with starlings ( Sturnus vulgaris ) shows that social foragers may also experience self-imposed costs to their feeding rates in order to remain in the presence of group members, despite a lack of physical interaction or overt aggression. I studied whether nutmeg …

Physiological costs of total cholesterol in European starlings across an urban to rural gradient
… total cholesterol in European starlings (<em>Sturnus vulgaris</em>)—an urban adapted species—across an urban and a rural site. We ask: (1) do urban starlings have elevated cholesterol, (2) does elevated cholesterol come at a physiological cost to birds, and (3) to what extent are parental and …

Comparing four indices of physiological stress in an urban-adapted songbird between urban and rural habitats
… species, the European starling (<em>Sturnus vulgaris</em>), so successful in both rural and urban areas. Literature on stress-urbanization relationship remains highly equivocal partly due to an array of different study systems being compared as well as to key methodological …

Sex Ratios and the City: Is parental corticosterone a mediator of the relationship between urbanization and offspring sex allocation?
… sex allocation in European starlings (<em>Sturnus vulgaris</em>) differs for animals in urban versus rural habitats and is related to parental CORT or condition. Finally, in Chapter Four, I discuss future considerations for how global change may alter sex allocation in animals and offer …

The city blues of an iridescent canary: physiological, behavioral, and developmental impacts of lead (Pb) on songbirds along an urban-to-rural gradient
… common urban adapter, the European starling (<em>Sturnus vulgaris</em>), to explore how lead exposure is correlated with behavior, physiology, and feather development along a gradient of urbanization. We captured 125 free-living starlings to measure feather lead concentrations, along with …

The Near Wake of a European Starling
The wake of a freely flying European starling (Sturnus vulgaris) was measured using high speed, time-resolved, particle image velocimetry, simultaneously with high speed cameras which imaged the bird. These measurements have been used to generate vector maps in the near wake that can be associated …

Testing the Urban Dulling Hypothesis in an Iridescent Passerine Bird
… We compared breeding European starlings (<em>Sturnus vulgaris</em>) captured across urban and rural sites to test the urban dulling hypothesis. Plumage coloration was estimated by extracting mean brightness (average area under the curve), full width half maximum (saturation; the width of the …

Biology and conservation of the endangered Bahama Swallow (Tachycineta cyaneoviridis)
… (Passer domesticus) and European Starlings (Sturnus vulgaris). These results highlight the importance of pine forest and the Hairy Woodpecker for the persistence of the swallow.

Bird utilization of habitat in residential areas
… a height of 30 ft; (spring R²=0.82). Starlings (Sturnus vulgaris) were ubiquitous, though more common in areas of dense housing; (winter R²=0.37, spring R²=0.34). House sparrows (Passer domesticus) were also associated with areas of dense housing and utilized ornamental architectural designs; …

The potential of restored landfill sites for biodiversity conservation in the UK
… Tree sparrow (Passer montanus) and Starling (Sturnus vulgaris). Habitat quality and landscape variables were found to be significant predictors for different species. Underlying soils were found to be an important factor in determining the heterogeneity of the plant communities within the …
