Visual Identification

Appearance

The Metallic Starling is a small, glossy black bird with red eyes and a striking iridescent sheen that reflects green and purple hues in sunlight. Its body is sleek and compact, with a short tail and pointed wings, giving it an aerodynamic profile.

Both males and females share similar plumage, with adults displaying the characteristic metallic sheen. Juveniles have a duller, sooty-brown appearance before developing their adult plumage.

Distribution

Metallic Starlings inhabit tropical and subtropical rainforests, woodlands, and mangroves across northern Australia, New Guinea, and nearby islands. They prefer dense forest canopies but can also be found in forest edges and clearings.

In Australia, they are common in the coastal and near-coastal areas of northern Queensland, particularly in the wet tropics region. Their distribution remains relatively stable throughout the year, with no significant seasonal variations.

Distribution Map

This map gives you a rough idea of where you might spot a Metallic 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:

  • More detailed maps for bigger countries, including state and region
  • How birds move around during different seasons

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.

Highly agile flyer capable of acrobatic manoeuvres and tight formations in dense forest canopies. Their sleek, aerodynamic build and pointed wings enable exceptional manoeuvrability, particularly useful for navigating through complex rainforest environments.

Strength 45

Strength

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

Whilst not particularly strong for their size, these small birds possess sufficient strength to carry nesting materials and construct substantial globular nests. Their modest 60-80g weight suggests moderate strength relative to similar-sized passerines.

Adaptability 78

Adaptability

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

Shows strong adaptability through their ability to thrive in various tropical and subtropical environments, from rainforests to mangroves. Their communal living strategies and varied diet of fruits and insects demonstrate good ecological flexibility.

Aggressiveness 60

Aggressiveness

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

Displays moderate aggression, primarily in defence of colonial nesting sites. Whilst not typically aggressive towards other species, their large colonial breeding habits suggest a reasonable degree of territorial behaviour during nesting season.

Endurance 70

Endurance

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

Demonstrates good endurance through sustained flight during foraging and flock movements. Their ability to maintain energetic social activities and regular foraging whilst caring for young indicates solid stamina, though they're not known for long-distance migration.

Diet

Metallic Starlings are primarily frugivorous, feeding on a variety of fruits, especially figs. They supplement their diet with insects, particularly during breeding season.

These birds play a crucial role in seed dispersal within their forest habitats, contributing to ecosystem health.

Behaviour

Metallic Starlings are highly social birds, often seen in large, noisy flocks. They exhibit acrobatic flight patterns, swooping and wheeling in tight formations.

These birds are known for their communal nesting habits, with multiple pairs building nests in close proximity, sometimes forming large breeding colonies.

Vocalisation

Metallic Starlings are vocal birds with a diverse repertoire. Their calls include a variety of chattering, whistling, and warbling sounds. In large flocks, they create a cacophony of metallic 'tink-tink' notes and high-pitched whistles.

During the breeding season, males produce more melodious warbling songs to attract mates.

Nesting & Breeding

Breeding occurs during the wet season, typically from October to March. Metallic Starlings form monogamous pairs within their larger colonies. They construct large, globular nests made of twigs, leaves, and vines, often suspended from the outer branches of tall trees.

Females typically lay 2-3 pale blue eggs with brown speckles. Both parents share incubation duties, which last about 14 days. The eggs are oval-shaped and have a smooth, slightly glossy surface.

Nestlings are altricial and remain in the nest for approximately 18-21 days before fledging. Parents continue to feed and care for the young for several weeks after they leave the nest.

Conservation and Status

Global Conservation Status

Least Concern [1]

While the Metallic Starling is currently listed as Least Concern, it faces localised threats from habitat loss due to deforestation.

Conservation efforts focus on protecting rainforest habitats and monitoring population trends, particularly in areas where their range overlaps with human development.

Birdwatching Tips

  • Look for large, noisy flocks in rainforest canopies
  • Listen for their distinctive chattering and whistling calls
  • Observe their acrobatic flight patterns during dawn and dusk
  • Search for their communal nesting sites in tall trees
  • In Australia, check mangrove areas and coastal forests

Did You Know?

  1. Metallic Starlings can form breeding colonies of up to 1,000 individuals.
  2. Their iridescent plumage is caused by the structure of their feathers, not pigments.
  3. These birds play a crucial role in rainforest regeneration through seed dispersal.
