Effects of exogenous 17(β) estradiol on the reproductive physiology and reproductive performance of european starlings (Sturnus vulgaris)
... We investigated the role of estradiol in the determination of primary reproductive effort in a free-living, nest-box population of European starlings (Sturnus vulgaris). Females were treated with estradiol ...

Metabolic power of European starlings Sturnus vulgaris during flight in a wind tunnel, estimated from heat transfer modelling, doubly labelled water and mask respirometry
... In the present study, we compared estimates of the energetic cost of flight determined by heat transfer modelling with those obtained by two independent techniques (DLW and mask respirometry). We collected data using all ...

Neuromuscular control and kinematics of intermittent flight in the European starling (Sturnus vulgaris)
... The conflicting evidence from the studies of finches and budgerigars makes it worthwhile to conduct additional experimental studies of intermittent flight in birds. A prediction that follows from the study of budgerigars ...

Population-Dynamics and Age Structure of Starlings (Sturnus vulgaris) in New Zealand
... The starling (Sturnus vulgaris) is one of the most abundant and widespread birds on Earth. Originally a native of Europe and Asia, it has expanded its range over the past hundred years, partly because of ...

Morphological and histological study of the liver in migratory starling bird (Sturnus vulgaris)
... The present work was aimed to form the baseline data of normal morphological and histological structure features of liver in migratory starling (Sturnus vulgaris). Anatomically, the starling liver bird was ...

Constitutive immune function in European starlings, Sturnus vulgaris, is decreased immediately after an endurance flight in a wind tunnel
... Life-history theory predicts that animals face a trade-off in energy allocation between performing strenuous exercise, such as migratory flight, and mounting an immune response. We experimentally tested this prediction ...

Drowning is an apparent and unexpected recurrent cause of mass mortality of Common starlings (Sturnus vulgaris)
... Drowning is infrequently reported as a cause of death of wild birds and such incidents typically involve individual, rather than multiple, birds. Over a 21-year period (1993 to 2013 inclusive), we investigated 12 ...

Body-Mass, Composition, and Survival of Nestling and Fledgling Starlings (Sturnus vulgaris) at Belmont, New Zealand
... (Sturnus vulgaris) population at Belmont, Lower Hutt, New Zealand, showed that nest productivity was low compared with other populations in New Zealand and ...

Behavioural investigation of polarisation sensitivity in the Japanese quail (Coturnix coturnix japonica) and the European starling (Sturnus vulgaris)
... As only behavioural tests can determine precisely what an animal perceives, we developed a behavioural test to investigate whether or not birds can see the e-vector orientation of polarised light reflected from objects. ...

Metabolic power, mechanical power and efficiency during wind tunnel flight by the European starling Sturnus vulgaris
