Common Starling
Sturnus vulgaris
The Common Starling is an introduced species and one of Australia's most damaging and widespread vertebrate pests. Brought to Australia in the late 19th century, it has established massive populations across the south-east of the country. Starlings are highly adaptable and aggressive, forming enormous flocks that can cause devastating economic losses to horticultural industries, particularly vineyards and olive groves. They are also a significant environmental threat, outcompeting many native bird species, especially hollow-nesters like parrots, for precious nesting resources. In urban areas, their large, noisy, and unhygienic communal roosts create significant nuisance and public health concerns due to the accumulation of droppings. Their management is a major challenge for both agricultural producers and urban authorities.
For effective control and prevention, professional pest management is recommended.

Biology & Lifecycle
Understanding Common Starling biology and development
Anatomy
Common Starling (Sturnus vulgaris) exhibits typical bird-and-pigeon anatomy with specialized adaptations. Body structure follows standard arthropod organization. Males and females are very similar. Males may be slightly glossier, and the base of the lower mandible is bluish in males and pinkish in females during the breeding season.. These anatomical features are optimized for their ecological role and contribute to their success in Australian environments.

Habitat & Distribution
Where Common Starling lives and thrives
Distribution Patterns
The Common Starling is native to the woodlands and grasslands of Europe and Asia but was deliberately introduced to Australia between the late 1850s and 1870s for cultural and sentimental reasons. The species has since become well-established and is expanding its range across eastern and southeastern Australia, becoming a prominent bird in open cultivated areas, orchards, and regions with human habitation. Originally introduced to Melbourne (Victoria), Brisbane (Queensland), Adelaide (South Australia), and Hobart (Tasmania), starlings have progressively extended their distribution southward and eastward. The species has recently spread to Western Australia, with established populations detected near Munglinup and Condingup between 2006–2009, though these incursions were subsequently eradicated through coordinated control efforts. A single bird was first recorded in Western Australia at Gingin in 1936. The species' ability to thrive in human-modified landscapes and its highly social behaviour have facilitated rapid range expansion. See Western Australia Department of Primary Industries and Regional Development and Australian Museum.
Behavior & Diet
Common Starling behavioral patterns and feeding habits
Vocalisation
A noisy mix of whistles, clicks, chatters, and screeches. It is a proficient mimic of other bird calls and environmental sounds.
Social Behavior
Extremely gregarious. Forages in flocks and forms massive communal roosts in winter, sometimes numbering in the tens of thousands. These roosts are noisy and produce vast quantities of droppings.
Territorial Behavior
Aggressively defends its nest site against other birds, including larger native species.
Movement And Migration
Generally sedentary but can be nomadic, especially in response to food availability. Young birds disperse widely after breeding.
Dietary Preferences
Feeding Behavior
Forages mostly on the ground, probing the soil with its beak for insects and larvae. In fruit crops, large flocks will descend and strip trees or vines with systematic efficiency.
Foraging Techniques
Probes the ground with an open beak to locate soil invertebrates. Forms huge feeding flocks in agricultural settings.
Primary Food Sources
- Invertebrates (insects, larvae, worms, snails), which form a large part of their diet, especially during breeding.
- Cultivated fruits, particularly grapes, olives, cherries, and berries, leading to major economic losses.
- Grains, seeds, and livestock feed.
- Human-provided food scraps and rubbish in urban areas.
Seasonal Diet Changes
Diet shifts from being protein-heavy (invertebrates) during the breeding season to fruit and grains in autumn and winter.
Economic Impact
Financial costs and economic effects of Common Starling
Common Starlings are a significant economic pest in Australia, causing severe damage to high-value horticultural crops including cherries, all grape varieties, blueberries, olives, stone fruits, apples, pears, and a range of vegetables. Whole berries are removed and swallowed, while larger fruit show characteristic peck-mark damage. Starlings also consume and spoil livestock feed, affecting intensive cattle, pig, and poultry production, reducing feed efficiency and raising costs. Property, industry, and infrastructure can be seriously damaged when starlings use manmade structures as roost and nest sites, and birds nesting under roofs can bring bird lice into houses. Roosting flocks, which can number up to 25,000 birds at a single site, are a major nuisance in urban areas, being unsightly, noisy, and contaminating surrounding areas with droppings. Accumulated waste is also a disease risk, providing a breeding ground for organisms that can cause illness in humans, so affected sites often require professional cleanup. Combined, direct crop losses, feed spoilage, infrastructure damage, and cleanup costs represent a substantial ongoing economic burden for growers, primary producers, and property owners across the starling's Australian range. See Department of Primary Industries and Regional Development (WA) and PestSmart, Centre for Invasive Species Solutions.
Detection & Signs
Early warning signs of Common Starling presence
Common Starlings are dark, chunky birds measuring 19–22 cm in length and weighing 38–80 grams. They are readily identified by their glossy black feathers with distinctive iridescent green and purple sheen, short square tail, and long, slender pointed bill. During breeding season, they appear uniformly glossy-black, while younger birds are duller grey-brown. After autumn moulting, adults develop pale-tipped feathers creating a distinctive spotted appearance. Their bills and legs transition from dark to yellow as seasons progress. Field signs of infestation include birds perching on livestock backs, large flocks flying in characteristic tight, coordinated formations, or massive roosting aggregations producing high noise levels. Accumulations of droppings and nesting material in roof cavities, building eaves, and other structures are prominent visible signs. Starlings breed from July to March in Australia, potentially producing up to three broods per year. Their nests are constructed from dry grass combined with twigs, leaves, and feathers, typically built in tree hollows or building cavities. Their tendency to forage in very large flocks—often numbering thousands—makes detection relatively straightforward in orchards, vineyards, and agricultural areas. See Department of Primary Industries and Regional Development (WA) and Australian Museum.
Prevention
Proactive strategies to prevent Common Starling infestations
Physical exclusion is the most effective long-term prevention method for protecting high-value crops. Install knitted mesh netting with apertures of 5 mm x 5 mm or less (when fully stretched), using strands at least 500 microns thick to prevent entanglement and bird escape. Netting must be installed tightly to tree trunks and kept taut over fruit crops using sturdy support frames constructed from PVC pipe or timber arranged in tepee formations around the tree. Proper tensioning using tent pegs or heavy objects wrapped in netting edges maintains barrier integrity. Netting should be tight enough that wildlife cannot create slack areas rather than sinking into it, preventing injury while excluding pests. Create overlapping flaps or access points to allow harvesting while maintaining barrier effectiveness. Additional structural barriers include spikes, mesh screens, and electrical barrier systems permanently installed on building roosting sites and infrastructure vulnerable to damage. Early intervention through seasonal surveillance and trapping programs, as implemented in Western Australia's south-east region near Munglinup and Condingup, prevents establishment of new populations. Successful prevention requires combining multiple approaches and regular monitoring for gaps or breaches in netting systems. See Queensland Government and Department of Primary Industries and Regional Development (WA).
Control Methods
Effective treatment options for Common Starling control
Lethal control methods include trapping and culling. Modified Australian Crow (MAC) traps and Myna traps are commonly used, with live-lure birds proving significantly more effective than water or sound lures for capturing starlings; a Wildlife Research field trial on South Australia's Eyre Peninsula found Myna traps caught roughly 1.5 times more starlings than MAC traps when both were fitted with live lures. Trapping is most effective when large flocks form to feed or roost, such as during summer congregations. Coordinated scare tactics for large flocks combine multiple sensory deterrents: strategically placed audio systems playing distress calls and predator sounds, paired with visual elements such as flashing lights and inflatable scare balloons. Roosting habits can also be modified using mesh, spikes, or electrical barrier systems on affected structures. Lethal methods used in Australia also include shooting and chemical control. Government agencies such as Western Australia's Department of Primary Industries pursue eradication when starlings are located in new regions, conducting seasonal surveillance and control programs to prevent establishment. Professional pest management services can coordinate large-scale control efforts for extensive infestations. See Wildlife Research: To catch a starling, Australian Environmental Pest Managers Association, PestSmart, Centre for Invasive Species Solutions, and Department of Primary Industries and Regional Development (WA).
