🔍 Identification: Male vs Female King Parrots
This is one of the most striking cases of sexual dimorphism in Australian birds.
| Feature | Male King Parrot | Female King Parrot |
|---|---|---|
| Head & Chest | Vivid, deep scarlet-red covering the entire head, neck, and chest. | Head and chest are a distinct, lush green. |
| Beak | Bright orange-red upper beak, black lower beak. | Uniformly grey-black beak. |
| Body | Brilliant green back, rump, and wings. | Green back and wings, but a duller shade than the male. |
| Belly | Red lower belly with a green undertail. | Red lower belly (the primary red on their body). |
Juveniles: Young birds of both sexes resemble the female (green head) until the male begins to moult into his red plumage at around 12-16 months.
🌰 The King Parrot Diet: Seed and Fruit Specialists
Their feeding habits are less destructive than cockatoos and less aggressive than lorikeets.
Natural Foraging

In the wild, they feed primarily on seeds from eucalypts, acacias, and casuarinas, as well as berries, fruits, and nuts. They often forage in the canopy or on the ground in clearings.
Backyard Feeding (What They Love)
King parrots readily adapt to backyard feeding. Their preferred offerings include:
-
Sunflower Seeds (especially in the shell or hearts)
-
Unsalted Peanuts (in the shell or pieces)
-
Commercial Large Parrot Seed Mixes
-
Fresh Corn on the cob
-
Apple slices and other soft fruits
Feeding Tip: They are ground and platform feeders. A sturdy, open tray or platform feeder is ideal. They are cautious and appreciate feeders placed near cover.
🗺️ Seasonal Movements & Behaviour
King parrots are known for their altitudinal migration in some regions.
-
Warmer Months (Spring/Summer): They often move to higher, cooler elevations in forested mountain ranges to breed.
-
Cooler Months (Autumn/Winter): They descend to lower elevations, including suburban gardens, parks, and farmlands, where food is more accessible. This is when backyard sightings are most common.
They are typically seen in pairs or small family groups, and are known for their calm, almost deliberate movements.
🏡 Attracting King Parrots to Your Garden
To attract king parrots, you need to provide safety, the right food, and patience.
-

Female King Parrot Offer Their Favourite Foods: Provide sunflower seeds and peanuts on a large, open platform feeder or directly on a cleared ground area.
-
Ensure a Sense of Security: Place feeders close to tree cover or dense shrubs so they can retreat quickly. They are wary of open, exposed areas.
-
Be Patient and Consistent: They are cautious. It may take weeks of regular, quiet feeding for them to become regular visitors. Avoid sudden movements.
-
Provide Water: A large, clean birdbath can be a major attractant, especially in drier months.
🆚 King Parrot vs. Other Backyard Parrots
Understanding their niche helps explain their behaviour.
| Comparison | Key Difference |
|---|---|
| King Parrot vs. Lorikeet | Diet clash. Lorikeets want nectar; king parrots want seeds. Lorikeets are far more aggressive and will dominate shared spaces. |
| King Parrot vs. Cockatoo | Size vs. Temperament. Cockatoos are more powerful and will dominate a food source, but king parrots are less destructive and much quieter. |
| King Parrot vs. Rosella | Size and Shyness. Both are seed-eaters, but king parrots are larger and can be bolder over time. Rosellas are more consistently shy. |
Gentle Giants: King parrots are often the “polite guests” at a feeder, less likely to engage in squabbles than other parrots.
🦜 Unique King Parrot Facts
1️⃣ Male and female colours are strikingly different
-
Male: bright red head and chest with green wings and back
-
Female: entirely green head and chest with red belly
-
Why it’s unique: Most other parrots (except lorikeets to some degree) have minimal sexual dimorphism. King parrots are textbook example of clear male vs female colouring.
2️⃣ They are more shy and elusive than most backyard parrots
-
Unlike lorikeets and galahs, they don’t swarm feeders
-
Often stay on the edge of trees, watching
-
Fun fact: People can go years without seeing them in urban gardens unless food is provided
3️⃣ Gentle giants of the parrot world
-
Calm and dignified compared to noisy cockatoos
-
Rarely destructive
-
Can become trusting and hand-fed with patience
-
Contrast: Lorikeets are hyper, cockatoos are destructive, rosellas shy and ground-focused
4️⃣ Nests high in tall eucalyptus trees
-
Prefer dense, tall forests or large suburban trees
-
Usually lay 2 eggs in a hollow
-
Female does most of the incubation while male feeds her
-
This behaviour is shared only partially with king parrot relatives — unique in urban-adapted parrots
5️⃣ They are not seed crushers
-
Mainly eat fruit, seeds, and some blossoms
-
Unlike cockatoos, they don’t have strong beaks for cracking hard nuts
-
Can survive well on a mixed diet of native fruit without damaging property
6️⃣ Can live very long lives
-
Wild: ~25 years
-
Captivity: up to 30+ years
-
Rare among backyard parrots — many rosellas and lorikeets live 15–20 years
7️⃣ Courtship is quiet but fascinating
-
Male often feeds female at the nest
-
Displays subtle head bobbing and wing flicks
-
Unlike lorikeets or cockatoos, which use loud displays, king parrots are understated romantics
8️⃣ Urban adaptation without chaos
-
They thrive in suburbs with large trees and native fruiting plants
-
Unlike lorikeets, they rarely dominate feeders
-
Makes them ideal for quiet backyard birdwatching
🤝 The Unique Trust of King Parrots
With consistent, quiet presence, king parrots can become remarkably trusting. It is not uncommon for them to:
-
Feed from a platform while a person stands motionless a few metres away.
-
Eventually take seed from a open hand (a process requiring immense patience and no sudden moves).
-
Become regular, predictable visitors who announce their arrival with soft whistles.
This trust is a privilege and should never be exploited or forced.

❓ Frequently Asked Questions
Q: Are king parrots endangered?
A: No. They are listed as Least Concern. However, habitat loss in some areas can put pressure on local populations. They are protected under Australian law.
Q: Can king parrots be kept as pets?
A: No. Like all native Australian parrots, they are protected wildlife. It is illegal to catch or keep them without a specific wildlife carer or exhibition license, which is not granted for pet purposes.
Q: Why do I only see king parrots in winter?
A: You likely live in a lower-altitude area. Their seasonal movement means they come down from forested highlands to suburban areas in autumn and winter, making them more visible in gardens during these cooler months.
Q: What should I do if I find an injured king parrot?
A: Contact a licensed wildlife rescuer immediately. Keep the bird in a dark, quiet, and ventilated box. Do not offer food or water unless instructed by the rescuer, especially if the bird is weak.
Q: Are they aggressive to other birds?
A: Generally, no. They are one of the least aggressive large parrots. They may hold their ground but are more likely to yield to dominant species like cockatoos or lorikeets.
Q: Are king parrots aggressive?
A: No. King parrots are known for their cautious and gentle temperament, often described as the “gentle giants” of backyard parrots. They are far less likely to squabble at feeders compared to lorikeets or cockatoos, typically preferring to observe and wait their turn.
Q: Can king parrots bite?
A: Yes, they can, but they are generally not prone to biting. A king parrot’s bite is a defensive reaction if it feels threatened or cornered, not an act of aggression. Their powerful beak can deliver a painful nip, which is why you should never attempt to handle a wild bird. I have never been bitten by a king parrot and I HAVE handfed them in the past.
📏 King Parrot Size: Measurements & Comparisons
Here is a breakdown of the Australian King Parrot’s size, how it compares to other common parrots, and the differences between ages and sexes.

Male and female king parrots are very similar in size and weight; the primary difference is their stunning colouration, not their dimensions.

| Stage | Size | Key Identifying Features |
|---|---|---|
| Juvenile (Fledgling) | Near adult size by the time they leave the nest. | Both sexes look like the adult female (green head). Beak is dark grey. |
| Immature Male | Adult size. | Begins to show patches of red feathers mixed with green on the head and chest over 12-18 months. Beak starts to turn red. |
