Summary of InvasivenessTop of page
Native to Europe, Asia and North Africa, Sturnus vulgaris (the European starling) has been introduced globally, save in Neotropical regions. The European starling prefers lowland habitats and is an aggressive omnivore. S. vulgaris costs hundreds of millions of dollars in agricultural damage each year (estimated annual cost to agriculture in the USA is $800 million, based on $5/ha damage; Linz et al. 2007). S. vulgaris also contributes to the decline of local native bird species through competition for resources and nesting spaces. S. vulgaris can also act as a disease vector with implications for livestock and human health. The European starling has been nominated as among 100 of the "World's Worst" invaders.

DescriptionTop of page
The European starling (Sturnus vulgaris) is a small bird approximately 21.5cm, long and weighing around 70 to 100grms. Iridescent green glossed feathers cover the nape, breast and back of the bird, whilst the wings are black, sometimes with a green or purple veneer. During the winter white flecking may appear on the starling's breast (Chow, 2000).
DistributionTop of page
Native range: Europe, Southwest Asia and Northern Africa.
Known introduced range: North America, South Africa, New Zealand, and Australia (Adeney, 2001). After numerous failed attempts, an introduction in New York in 1890 and 1891 led to the permanent establishment of European starlings in North America; all or most of the starlings in North America, Central America and the Caribbean are thought to derive from the 16 pairs originally introduced to New York (Linz et al. 2007).

HabitatTop of page
European starlings (Sturnus vulgaris) prefer lowland habitats to more mountainous terrain. They are secondary cavity nesters, using extant cracks, crevices, and cavities created by other species. During breeding season the European starling requires holes for nesting and vegetation fields for feeding. The rest of the year it will utilise a wider range of habitats from moorland to salt marshes. European starlings are highly adaptable when selecting nest hollows, e.g. fence posts, roof linings under guttering (there has been an observation of a starling nest in the wool of a live sheep) (John Tracey, pers. comm., 2004).

Biology and EcologyTop of page
European starlings (Sturnus vulgaris) are omnivores and subsist mainly on seeds, insects, invertebrates, plants and fruit (Chow, 2000).
Reproduction is sexual; oviparous. Breeding season in the Northern Hemisphere generally begins late March and runs through to early July. The Southern Hemisphere breeding season runs between September and December. European starling clutches contain between 4-6 blue-green eggs. Females may lay as many as three clutches in a single breeding season (Kern, 2003, Chow, 2000).
Eggs incubate in the nest for up to 15 days. The juvenile European starling (S. vulgaris) will stay in the nest for 21 to 23 days and may continue to beg parents for food for a few days after leaving the nest. Banding studies have shown that European starlings can live up to 21 years in the wild. (Chow, 2000, CWBO, 2004).
European starlings are gregarious and often form huge flocks of upwards of 3,000 birds.

Means of Movement and DispersalTop of page Introduction pathways to new locations
Biological control: European starlings (Sturnus vulgaris) were introduced to New Zealand to control local insect populations
For ornamental purposes: European starlings (Sturnus vulgaris) were allegedly introduced to the U.S. as part of a movement to introduce all the birds of Shakespeare to the States.
Natural dispersal: European starlings (Sturnus vulgaris) have spread into Canada and Northern Mexico from the US.
Transportation of domesticated animals: People may move European starlings (Sturnus vulgaris) to new areas by taking their pet birds with them.

Impact SummaryTop of page
ImpactTop of page
European starlings (Sturnus vulgaris) cause damage to agricultural crops. When significant numbers are present, starling flocks may descend on fruit and grain crop fields to forage; this causes massive damage and can have a heavy economic effect. European starlings are extremely aggressive omnivores, and will compete with native fauna for food. Open bill probing is most commonly used for ground invertebrates, which is their preferred food. Hence this provides the European starling with an evolutionary advantage over frugivores. Fruit damage is often found to be caused by a higher proportion of juveniles, which have underdeveloped probing skills (Brochier, 2010). Usurping nests by contamination (as well as physical competition) is also a major problem (e.g. native parrots use little, if any, bedding, whereas starlings will rapidly fill and contaminate tree hollows).
European starlings are also a public nuisance and can damage infrastructures, roof linings, etc. and negatively affect aesthetics (Weber 1979). Urban problems can be enhanced during the winter when they seek shelter and warmth. In addition, because of their large flocks, when they roost near airports there is the potential for bird-aircraft collisions which can result in jet engine damage and loss of human life (Linz et al. 2007).
S. vulgaris are recognised as a potential human and animal health hazard; they carry many infectious organisms and have been implicated in the transmission of numerous human and animal diseases (see Linz et al. 2007 for a review). Recent concerns include contamination by starlings of livestock feeding facilities; such concerns have arisen because of their tendency to congregate and contaminate feeding facilities and to interact closely with cattle. Kauffman et al. (2011) showed that S. vulgaris can carry the pathogen Escherichia coli O157:H7 from farm to farm and transmit infection to cattle, this threatens human health through meat consumption. Carlson et al. (2011) found that local control of S. vulgaris at a concentrated animal feeding operation could be used as a component in the control of the foodborne pathogen Salmonella enterica.
Risk and Impact FactorsTop of page Invasiveness
- Capable of securing and ingesting a wide range of food
- Negatively impacts agriculture
- Threat to/ loss of native species
- Competition - monopolizing resources

UsesTop of page
European starlings (Sturnus vulgaris) play an active role in the control of insect populations. Many people also consider the starling to be aesthetically pleasing, and keep them as pets (Adeney, 2001).
Uses ListTop of page
- Biological control
- Pet/aquarium trade
Similarities to Other Species/ConditionsTop of page
The most similar species to the European starling are the other blackbirds. The Common Grackle (Quiscalus quiscula), the Brown-headed Cowbird (Molothrus ater) and the Red-winged Blackbird (Agelaius phoeniceus) are the most common eastern blackbirds. All three of these species have dark bills and legs, which distinguishes them from the European Starling (GWW, 2000). Another similar species, the common blackbird (Turdus merula), is also invasive in some parts of its range (John Tracey, pers. comm., Sept. 2004).
Prevention and ControlTop of page
Physical/mechanical: Non-lethal methods are commonly used, such as warding starlings away using sonic devices, hawk kites, or propane exploders. However, non-lethal methods often have only a temporary effect (Linz et al., 2007). Other methods include exclusion, anti-perching devices and shooting. (Adeney, 2001; Kern, 2003; Campbell, 2012). Trapping followed by euthanasia is also used as a control method. In this case, a live bird may be placed in the trap so that other starlings are lured more effectively, because as gregarious birds, European starlings are often attracted to traps containing a live conspecific (Campbell, 2012).
Chemical: Lethal or deterrent chemicals are used (Campbell, 2012). Linz et al. (2007) mention the exampe of 4-aminopyridine which can be both lethal and a deterrent (not only can it be fatal to birds that ingest it, ingestion causes birds to give warning cries which frighten away other birds). Lethal chemicals are often associated with problems of lethality to non-target organisms.
