Common Starling Bird Facts (Sturnus vulgaris)

Visual Identification

Appearance

The Common Starling is a small, stocky bird with a short tail and pointed wings. Its plumage is glossy black with an iridescent sheen, displaying hues of green and purple in bright light. The bill is yellow in the breeding season and darker in winter.

Females are mostly similar to males, although they tend to be. They also develop the bright yellow bill during the breeding season, although the bill base tends to be pinkish in females. Females also tend to be a little less glossy than males and have shorter feathers on the throat.

During winter, the bird's feathers are covered in white spots, giving it a speckled appearance. Juveniles are uniformly dull brown before moulting into adult plumage.

In North America, Australia, and New Zealand, starlings are considered an invasive species. They are abundant year-round residents in the UK, widespread across the US, and common in urban areas of Canada and Australia.

Distribution Map

This map gives you a rough idea of where you might spot a Common Starling. The coloured areas show countries where these birds have been seen.

A few things to keep in mind:

Birds might not be everywhere in the coloured areas, for example, they may be present around the coast of that country
Where birds live can change with seasons and available food
This map is quite simple - it doesn't show exact locations

We're working on making our maps even better! Soon, we hope to show you:

Bird Attributes Explained

Our bird attributes system rates various aspects of a bird's capabilities on a scale of 0-100, based on data from field observations, scientific studies, and expert knowledge.

Attribute Categories:

Agility: Manoeuvrability, speed, and grace in flight or movement.
Strength: Physical power, often correlating with size and hunting abilities.
Adaptability: Ability to thrive in various environments or changing conditions.
Aggressiveness: Territorial behaviour and assertiveness, particularly during breeding seasons.
Endurance: Stamina, often seen in migration patterns or foraging behaviours.

Understanding the Ratings:

0-20: Very Low
21-40: Low
41-60: Average
61-80: High
81-100: Very High

Remember, these attributes are relative to other bird species and don't necessarily indicate superiority.

Agility 85

Agility

Reflects the bird's manoeuvrability, speed, and grace in flight or movement.

The Common Starling demonstrates remarkable agility, particularly evident in their spectacular aerial displays known as murmurations. Their ability to perform synchronised, complex flight patterns in large flocks showcases their exceptional manoeuvrability and spatial awareness.

Strength 60

Strength

Indicates the bird's physical power, often correlating with size and hunting abilities.

Whilst not exceptionally strong for their size, Common Starlings possess adequate strength for their lifestyle. Their ability to probe soil for invertebrates and defend nesting sites indicates a moderate level of physical prowess relative to their small stature.

Adaptability 95

Adaptability

Represents the bird's ability to thrive in various environments or changing conditions.

Common Starlings exhibit extraordinary adaptability, thriving in diverse habitats from urban areas to farmlands and woodlands. Their success as an invasive species in multiple continents further underscores their remarkable capacity to adapt to new environments and food sources.

Aggressiveness 70

Aggressiveness

Measures the bird's territorial behaviour and assertiveness, particularly during breeding seasons.

These birds display a moderate level of aggressiveness, particularly during breeding season when defending nesting sites. Their success in competing with native species in introduced ranges suggests a certain level of assertiveness, though they are not considered exceptionally aggressive among bird species.

Endurance 75

Endurance

Reflects the bird's stamina, often seen in migration patterns or foraging behaviours.

Common Starlings demonstrate good endurance, evidenced by their ability to perform extended aerial displays and their success as partial migrants. Their capacity to thrive in various climates and altitudes up to 1000 metres also indicates robust endurance, though they are not known for extreme long-distance migrations.

Diet

Common Starlings are omnivorous and opportunistic feeders. Their diet includes insects, worms, snails, and a variety of fruits and berries.

They often forage on the ground, using their strong bills to probe the soil for invertebrates. In urban areas, they readily take advantage of human food scraps.

Behaviour

Common Starlings are highly social birds, often seen in large, noisy flocks. They perform spectacular aerial displays called murmurations, where thousands of birds swoop and wheel in synchronised patterns.

These birds are also known for their ability to mimic sounds, including human speech and mechanical noises.

Vocalisation

Common Starlings are known for their diverse and complex vocalisations. Their natural song is a series of whistles, warbles, and rattles. They are excellent mimics, capable of imitating other bird calls, frog croaks, and even human speech or mechanical sounds.

The typical call is a harsh, descending whistle that sounds like 'tseer'. Starlings often call to signal aggression, maintain contact with other starlings, and alert other birds to sources of danger.

Nesting & Breeding

Breeding season for Starlings typically begins in spring. Males attract females by singing and displaying at potential nest sites, often returning to the same location each year.

Nests are built in cavities, including tree holes, buildings, and nest boxes. The nest is a loose collection of grass, leaves, and other plant material. Females lay 4-6 pale blue eggs. Some eggs may appear more greenish or whitish than blue, however.

Incubation lasts about 12 days, and both parents share duties. Nestlings fledge after 21-23 days but continue to be fed by their parents for 1-2 weeks after leaving the nest.

Conservation and Status

Global Conservation Status

Least Concern ^[1]

While the Common Starling is listed as Least Concern globally, populations have declined in parts of Europe and North America.

In the UK, it is on the Red List of conservation concern due to breeding population declines. Conservation efforts focus on maintaining suitable habitats and nesting sites.

Population Data

Global Population Estimate

250,000,000 mature individuals ^[2]

Global Population Trend

Trend data may be uncertain or fluctuating

Birdwatching Tips

Look for starlings in open areas like parks, fields, and urban settings
Listen for their varied vocalisations, including mimicry of other birds and sounds
Observe large flocks performing murmurations at dusk, especially in autumn and winter
In the UK and US, starlings are common year-round, making them easy to spot in urban and suburban areas

Predators

Common Starlings face predation from various birds of prey, including hawks, falcons, and owls. In urban areas, domestic cats are also significant predators, especially of fledglings and juveniles.

Did You Know?

Starlings can open their bills while they're closed in something solid, using a special adaptation in their skull.
A group of starlings is called a 'murmuration', which can contain up to 100,000 birds.
Starlings were introduced to North America in 1890 by a group that wanted to bring all birds mentioned in Shakespeare's works to the New World.
Winter roosts of starlings can hold up to several million birds.

FAQs

Why starlings are a problem

Starlings are considered a pest in the United States agricultural sector because they cause millions of dollars in damage to fruit crops and consume large amounts of animal feed.

They are also a nuisance in urban and suburban areas because of the mess they leave around roost sites and their habit of nesting in buildings. Starlings frequently outcompete native species for nest sites and food resources.
