چکیده

Although the starling has the capacity for explosive population growth, its population in Britain has declined by two-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 in the latter is much lower; the total breeding population is estimated at 9 million birds. In general, breeding productivity has increased, while survival, particularly of juveniles, has shown periods of decrease. The decline on farmland has been greater in pastoral areas, and is probably linked to reduced foraging opportunities associated with more intensive agricultural management. There is some evidence for a decline in urban populations, but data are scant and possible reasons for decline there are unclear.

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 incidents of mortality of multiple (2 - 80+) Common starlings (Sturnus vulgaris) in Great Britain that appeared to be due to drowning. More than ten birds were affected in ten of these...

De Novo Assembly of the Liver Transcriptome of the European Starling, Sturnus vulgaris

The European starling, Sturnus vulgaris, is a prolific and worldwide invasive species that also has served as an important model for avian ecological and invasion research. Although the genome sequence recently has become available, no transcriptome data have been published for this species. Here, we have sequenced and assembled the S. vulgaris liver transcriptome, which will provide a foundati...

Intraspecific Nest Parasitism in the Starling (sturnus Vulgaris) in Northwestern Croatia

Dolenec, Z.: Intraspecific nest parasitism in the starling (Sturnus vulgaris) in northwestern Croatia. Nat. Croat., Vol. 10, No. 4., 315–320, 2001, Zagreb. This study reports intraspecific nest parasitism in starlings (Sturnus vulgaris) in the village of Mokrice, northwestern Croatia, in 1999 and 2000. Twenty one (30.5%) out of 70 observed nests during the two years contained one or two parasit...

Directionality of Avian Vocalizations: a Laboratory Study’

Pure tones of 1, 2, 4, 8, and 10 kHz were broadcast from the body of a dead starling Sturnus vulgaris, and sound pressure levels were measured through 360” in three planes. At high frequencies (8 and 10 kHz) there were large troughs in sound pressure levels in the acoustic “shadow” of the bird’s body. A physical model based on sound interference phenomena predicts similar patterns of sound pres...
