How to Identify Starling

How to Identify Starling?

Identifying a starling might seem challenging at first glance due to its seemingly plain appearance, but with a closer look and attention to detail, you can distinguish this bird from others. 

Starlings belong to the family Sturnidae and are known for their gregarious behavior and remarkable vocal abilities. Here are some of the key points to help you identify a starling:

Size and Shape

Starlings are small to medium-sized birds, measuring 8 to 9 inches (20 to 23 cm) in length. They have a stocky build, short, triangular wings, and a relatively short tail. Their bodies appear somewhat rounded when perched.


While starlings may appear black from a distance, a closer look reveals a glossy iridescence to their plumage. 

Their feathers shimmer with shades of green, purple, and bronze, particularly during the breeding season. However, in non-breeding plumage, they may appear duller, with more muted colors.


Starlings have a slender, pointed bill that is slightly yellowish during the breeding season. Outside of the breeding season, their bills may appear darker. The bill is relatively long compared to the size of their head.


The eyes of a starling are dark and relatively small in proportion to the size of their head. They often appear shiny and give the bird a keen, intelligent expression.


Starlings are highly social birds and often congregate in large flocks, especially during the non-breeding season. Their flight patterns are swift and agile, with rapid wingbeats and sudden changes in direction.


One of the most distinctive features of starlings is their impressive vocal repertoire. 

They are proficient mimics and can imitate the calls of other birds and various sounds, including human-made noises. Their songs are often complex and harmonious.


Starlings are adaptable birds found in various habitats, including urban areas, farmland, woodlands, and grasslands.

They are commonly seen foraging for food in open fields or on lawns, probing the ground with their bills for insects and other invertebrates.


Regarding geographical distribution, starlings are native to Europe, Asia, and North Africa. 

However, they have been introduced to many other parts of the world, including North America, Australia, and New Zealand, where they are often considered invasive due to their aggressive behavior and negative impact on native bird species.

By paying attention to these key characteristics, you can confidently identify a starling and appreciate its unique beauty and behavior.

Behavior and Social Structure of Starling

Behavior and Social Structure of Starling

The common starling (Sturnus vulgaris) is renowned for its complex social behavior and remarkable adaptability, contributing to its success as a species. Here’s an overview of the behavior and social structure of starlings:

Gregarious Nature

Starlings are highly social birds that often gather in large flocks, particularly outside the breeding season. 

These flocks can consist of hundreds or even thousands of individuals and serve various purposes, including foraging, roosting, and protection from predators.

Roosting Behavior

At dusk, starlings congregate in communal roosts, often in dense vegetation or urban structures such as buildings and bridges. 

These roosts can be huge, with thousands of birds coming together in a synchronized display called a murmuration. 

During murmurations, starlings perform intricate aerial maneuvers, creating mesmerizing patterns in the sky.

Breeding Behavior

While starlings are gregarious outside the breeding season, they become more territorial and solitary during the breeding season. 

Males establish territories and engage in courtship displays to attract females. These displays often involve singing and aerial acrobatics.


Starlings typically nest in cavities, including tree hollows, buildings, and nest boxes. They are known to be opportunistic nesters, readily adopting artificial structures for nesting purposes. 

The female constructs the nest using grasses, twigs, and other plant materials, often lining it with feathers or other soft materials.

Parental Care

Both parents participate in incubating the eggs and feeding the nestlings. 

Starlings provide their young with a diverse diet, including insects, fruits, seeds, and even scraps of human food scavenged from urban areas.


Starlings are accomplished vocal mimics and can imitate a wide range of sounds, including the calls of other bird species and human-made noises such as car alarms and cell phone ringtones. 

They use vocalizations to communicate within the flock, during courtship, and defend territories.

Feeding Behavior

Starling Feeding Behavior

Starlings are omnivorous birds with a varied diet. They primarily feed on insects and other invertebrates during the breeding season but switch to a more plant-based diet outside the breeding season, including fruits and seeds. 

They are often seen foraging on the ground, probing the soil with their bills in search of food.


While some populations of starlings are sedentary, others undertake seasonal migrations, particularly in regions with harsh winter conditions. 

These migrations can involve long-distance movements, with some birds traveling thousands of kilometers to reach their wintering grounds.

Starlings’ behavior and social structure reflect their adaptability and resilience as a species, allowing them to thrive in a wide range of habitats and environmental conditions.

Reproduction and Life Cycle of Starling

The reproduction and life cycle of the common starling (Sturnus vulgaris) follow a typical pattern for passerine birds, characterized by seasonal breeding, nest-building, incubation, and parental care. 

Here’s an overview of the reproduction and life cycle of starlings:

Breeding Season

The breeding season for starlings typically begins in late winter or early spring, but it varies somewhat depending on geographical location and local climate conditions. 

Migratory populations may begin breeding later upon reaching their breeding grounds.

Courtship and Pair Formation

During breeding, male starlings establish territories and engage in elaborate courtship displays to attract females. These displays often involve singing, puffing up of feathers, and aerial acrobatics. 

Once a pair bond is formed, the male and female select a suitable nesting site.

Nest Building

Starlings are cavity nesters and will utilize a variety of natural and artificial structures for nesting, including tree hollows, buildings, and nest boxes. 

The female is primarily responsible for constructing the nest, typically made of grasses, twigs, and other plant materials, lined with softer materials such as feathers and moss.

Egg Laying and Incubation

Starling Egg Laying and Incubation

The female starling typically lays a clutch of 4 to 6 eggs, although sizes vary. She incubates the eggs for about 12 to 14 days, during which time the male may assist with incubation duties by bringing food to the female.

Hatching and Nestling Stage

Once the eggs hatch, both parents actively feed and care for the nestlings. The nestlings are initially altricial, meaning they are born naked and helpless, requiring constant care and feeding from the parents. 

The parents feed the nestlings a diet of insects and other small invertebrates.


The nestlings remain in the nest for about 18 to 22 days before they fledge or leave. During this time, they rapidly develop their flight feathers in preparation for independent flight. 

After fledging, the young birds are temporarily dependent on their parents for food and protection.

Post-Fledging Care

After fledging, the young starlings gradually become more independent but continue to rely on their parents for food and protection. 

The parents continue to feed and care for the fledglings until they can fend for themselves and join the adult flock.

Subsequent Breeding Attempts

In favorable conditions, starlings may raise multiple broods in a single breeding season, with pairs often reusing the same nest site for subsequent clutches.

The life cycle of starlings is closely tied to seasonal changes in food availability and environmental conditions, with breeding activities timed to coincide with periods of abundance and favorable weather. 

This reproductive strategy allows starlings to maximize their reproductive success and ensure the survival of their offspring.

Conservation Status and Threats for Starling

Conservation Status and Threats for Starling

The common starling (Sturnus vulgaris) is listed as a species of “Least Concern” on the International Union for Conservation of Nature (IUCN) Red List. 

However, despite this relatively stable conservation status, several threats and conservation concerns warrant attention:

Habitat Loss

Habitat loss and degradation due to urbanization, agricultural intensification, and deforestation are significant threats to starling populations. 

Loss of nesting sites, such as old trees and natural cavities, can negatively impact breeding success.

Pesticides and Pollution

Starlings are vulnerable to the effects of pesticides and pollutants, particularly those used in agricultural areas. 

Exposure to pesticides can lead to direct mortality or sublethal effects such as reduced reproductive success and compromised immune function.

Competition with Invasive Species

In some regions, starlings face competition for nesting sites and food resources from invasive species such as house sparrows (Passer domesticus) and European starlings (Sturnus vulgaris), which can negatively impact their populations.

Climate Change

Climate change threatens starlings through its effects on weather patterns, habitat suitability, and food availability. 

Changes in temperature and precipitation regimes can disrupt breeding and migration patterns, affecting nesting timing and insect prey availability.


Starling nests and nestlings are vulnerable to predation by various predators, including birds of prey, mammals, and introduced species such as rats and cats. 

Predation pressure can increase where natural predators are scarce, or nest sites are easily accessible.

Disease and Parasites

Starlings are susceptible to various diseases and parasites, including avian pox, avian influenza, and parasitic infestations. 

Disease outbreaks can significantly impact local populations, particularly in areas where birds congregate in high densities.

Collision with Structures

Collisions with buildings, communication towers, and other structures threaten starlings, especially during nocturnal migrations or dense flocking behavior. 

These collisions can result in injury or mortality, particularly for birds flying at high speeds.

Overhunting and Poaching

While not a significant threat in many regions, overhunting and poaching for food, sport, or pest control purposes can impact local starling populations, particularly in areas where hunting regulations are not adequately enforced.

Conservation efforts to address these threats include habitat conservation and restoration, pesticide regulation and mitigation measures, monitoring and research on population trends and ecology, and public education and awareness campaigns. 

Addressing these threats and implementing targeted conservation actions can ensure the long-term survival of starling populations and maintain their critical ecological roles.

Wrapping Up

The common starling (Sturnus vulgaris) is a resilient and adaptable bird species, known for its complex social behavior, impressive vocal abilities, and remarkable adaptability to various habitats. 

Despite facing threats such as habitat loss, pesticides, and competition with invasive species, concerted conservation efforts can help ensure the continued survival of starling populations. 

By addressing these challenges and promoting habitat conservation, we can safeguard the future of this iconic bird species’ future and maintain their ecosystems’ ecological balance. Thank you so much.
