The European Starling (Sturnus vulgaris), also known as the Common Starling, is a medium-sized passerine bird that has become one of the most widespread and recognized species worldwide. Native to Europe, the bird has been introduced to several other regions, where its rapid adaptation and population growth have led to its classification as an invasive species in some areas. Known for its glossy black plumage with iridescent hues, the starling is a social bird with complex vocal abilities, making it a fascinating yet controversial species.
The European Starling was first described by Carl Linnaeus in 1758 in his work Systema Naturae, where he classified it as Sturnus vulgaris. The genus name Sturnus is derived from the Latin word for starling, while vulgaris means “common” in Latin, highlighting the bird’s abundance in its native range. The species has several subspecies, showing slight variations in size and plumage depending on geography.
Scientific Classification:
- Kingdom: Animalia
- Phylum: Chordata
- Class: Aves
- Order: Passeriformes
- Family: Sturnidae
- Genus: Sturnus
- Species: Sturnus vulgaris
Recognized Subspecies:
The European Starling has 12 recognized subspecies, with some debate among ornithologists about the validity of certain intergrades and local forms.
| Subspecies | Region |
|---|---|
| S. v. vulgaris | Most of Europe and Asia |
| S. v. zetlandicus | Shetland and Faroe Islands |
| S. v. faroensis | Faroe Islands |
| S. v. tauricus | Eastern Europe, southern Ukraine, and Turkey |
| S. v. poltaratskyi | Russia and western Asia |
| S. v. nobilior | Central Asia and Iran |
Many of these subspecies exhibit clinal variation in size, and the extent of white spotting in their plumage, particularly during the winter months.
Description
The European Starling is a medium-sized passerine, characterized by its striking iridescent black plumage, often reflecting hues of purple and green. The species displays noticeable seasonal changes in its appearance, with individuals showing more prominent white spotting during the non-breeding season due to the tips of fresh feathers.
Physical Characteristics:
- Size: 19–23 cm (7.5–9.1 inches) in length.
- Wingspan: 31–44 cm (12–17 inches).
- Weight: 58–101 grams (2.0–3.6 oz).
The adult male and female look alike, but males tend to have longer throat feathers, especially during the breeding season. Juveniles are typically duller, with gray-brown plumage before molting into their adult feathers. The legs are stout and pinkish, and the bill undergoes seasonal color changes: it is black in winter but turns bright yellow during the breeding season.

| Europe | Native |
| Asia (Western and Central) | Native |
| North America | Introduced and invasive |
| Australia/New Zealand | Introduced and invasive |
| South Africa | Introduced and invasive |
| South America | Introduced and invasive |
Population Estimates:
The global population of European Starlings is estimated to be 150–200 million individuals. Despite significant declines in parts of Europe, particularly the UK and Scandinavia, due to agricultural changes and habitat loss, the species remains abundant globally.
Habitat
European Starlings thrive in a wide variety of habitats, ranging from open woodlands to urban environments. They have a remarkable ability to adapt to human-altered landscapes, making them common in cities, towns, and agricultural areas.
Preferred Habitat:
- Urban Areas: Cities, parks, gardens, and building crevices.
- Farmland and Grasslands: Agricultural fields and meadows where they can forage for insects.
- Woodlands and Forest Edges: Particularly during breeding, starlings use tree cavities for nesting.
- Suburban Areas: Frequently found in gardens and near human settlements.
| Habitat Type | Characteristics |
|---|---|
| Urban Areas | Cities, parks, and residential areas |
| Farmlands | Agricultural land with access to food sources |
| Woodlands | Open forests and edge habitats |
Behavior
The European Starling is highly gregarious and often forms large flocks, especially outside of the breeding season. Their spectacular murmurations—mass synchronized flocking—are a common sight, particularly during migration and roosting periods.
Vocalizations:
European Starlings are famous for their complex songs and mimicry of other bird species and even mechanical sounds. Their song consists of whistles, clicks, and squawks, and males are the primary singers, especially during the breeding season. Each male starling has its own repertoire of sounds, which can include imitations of other bird species and man-made noises like car alarms.
| Behavioral Aspect | Description |
|---|---|
| Social Structure | Forms large flocks, often seen in murmuration |
| Vocalizations | Complex mimicry; whistles, clicks, squawks |
| Territoriality | Males defend nest sites during breeding season |
Flight:
European Starlings have a distinctive, strong flight pattern with rapid wingbeats, often punctuated by short glides. During flocking, their synchronized movements create swirling patterns in the sky, known as murmurations.
Feeding
European Starlings are omnivorous and consume a wide variety of foods. They use a specialized feeding technique called “gaping,” where they insert their bill into the ground or vegetation and open it to expose hidden prey.
Primary Diet Components:
- Invertebrates: Insects (beetles, grasshoppers, caterpillars), spiders, and earthworms are the main food source during the breeding season.
- Fruits and seeds: During fall and winter, they consume berries, fruits, and seeds from plants like hawthorn and holly.
- Human food: In urban areas, starlings are opportunistic feeders, scavenging food scraps and foraging in landfills.
| Diet Component | Examples |
|---|---|
| Invertebrates | Beetles, caterpillars, spiders, earthworms |
| Fruits and Seeds | Berries from hawthorn, holly, and ivy |
| Human food sources | Scavenged scraps, food waste |
Breeding
European Starlings are cavity nesters, typically breeding in natural cavities, such as tree holes or artificial nest boxes. They are highly territorial during the breeding season, with males singing and displaying to attract mates.
Breeding Details:
- Clutch Size: 4–5 eggs, pale blue in color.
- Incubation Period: 12–14 days, mainly by the female.
- Fledging: Chicks fledge after approximately 21–23 days.
- Nesting Behavior: Males build loose nests from grass, feathers, and other soft materials in cavities. Females finish the nest once paired.
| Breeding Characteristic | Description |
|---|---|
| Clutch Size | 4–5 pale blue eggs |
| Incubation Period | 12–14 days |
| Fledging Time | 21–23 days |
| Nesting Sites | Tree cavities, nest boxes, building crevices |
Threats and Conservation Status
The European Starling is listed as a species of Least Concern by the IUCN, despite local population declines in parts of Europe. In its introduced range, however, the starling is often considered a pest due to its impact on native species and agriculture.
Major Threats:
- Habitat Loss: In parts of northern and western Europe, declines in grassland invertebrates due to changes in farming practices have affected chick survival rates.
- Competition: Starlings often outcompete native species for nesting sites, particularly in regions where they are invasive.
- Agricultural Damage: Starlings feed on fruits and sprouting crops, causing damage to vineyards and orchards.
| Threat | Impact |
|---|---|
| Habitat Loss | Reduced food availability for chicks |
| Competition | Displaces native species from nest sites |
| Agricultural Damage | Significant impact on fruit and crop yields |
Migration
European Starlings exhibit partial migration. Populations in western and southern Europe are generally resident year-round, while those in northeastern Europe and Russia migrate south and west during the winter.
| Migration Type | Description |
|---|---|
| Partial Migration | Northeastern populations migrate in winter |
| Resident Populations | Western and southern populations are resident |
Conclusion
The European Starling is a highly adaptable species that has successfully colonized much of the world. While appreciated for its dazzling murmuration displays and complex vocalizations, the starling is also notorious as an invasive species that impacts agriculture and biodiversity. With a global population in the hundreds of millions, the species shows no signs of significant decline. However, ongoing management is necessary to mitigate its negative impacts in regions where it has been introduced.
