Bird of the Day: ​Violet-backed Starling

Violet-backed Starling: The Flying Amethyst You Need to See to Believe

If you close your eyes and picture a starling, your brain probably defaults to the European Starling—a glossy, speckled bird that, while undeniably clever, usually carries the reputation of an unwelcome backyard bully raiding your seed feeders. But today, I am going to ask you to forget everything you think you know about the family Sturnidae.

Meet the Violet-backed Starling (Cinnyricinclus leucogaster), also lovingly known as the plum-coloured starling or amethyst starling. If nature ever had a moment of pure, unadulterated luxury design, this is it. Looking at a male Violet-backed Starling under direct sunlight feels less like birdwatching and more like accidentally stumbling into a high-end jewelry store display that suddenly decided to sprout wings and fly away.

Grab your coffee, settle into your favorite reading chair (preferably near a window where you can glare lovingly at the local sparrows), and let’s dive into the fascinating biology, dramatic sexual dimorphism, and nomadic life of Africa’s most sensational songbird.

The Microscopic Magic Behind the Magenta: How to Identify One

If you stumble upon a flock of Violet-backed Starlings, your first reaction might be that you are looking at two entirely different bird species hanging out together. This species exhibits some of the most dramatic sexual dimorphism in the avian kingdom.

Quick Field Specs: Violet-Backed Starling

• Scientific Name: Cinnyricinclus leucogaster
• Length: 17–18 cm (approx. 7 inches, or roughly house-sparrow to bluebird sized)
• Weight: 35–56 grams (1.2–2.0 oz)
• Diet: Frugivorous & Insectivorous (wild figs, berries, swarming termites)
• IUCN Status: Least Concern

The Male: The adult male is nothing short of breathtaking. His head, nape, back, throat, and tail are wrapped in a cloak of deep, electric, iridescent violet-plum. This rich purple terminates abruptly at the upper breast in a sharp, clean line, yielding to an immaculate, snow-white belly and underside. He features a dark bill, dark legs, and a striking golden-yellow iris that pops against his purple crown.

Here’s the fun science bit: that purple color isn't caused by a violet pigment at all. Bird feathers generally don't produce purple dye. Instead, this jaw-dropping hue is the result of structural coloration. According to research published on avian iridescence, the barbules of their feathers contain tiny, microscopic stacks of hollow melanosomes. These structures refract and scatter light like millions of tiny glass prisms. In cloudy weather or deep shade, the male can look surprisingly dark or dull brown-purple—but the moment a ray of sunshine hits his back, BOOM! It ignites into liquid amethyst.

The Female: If the male is a disco ball, the female is a master of understated classic camouflage. She looks remarkably like a small thrush or a pipit. Her upperparts are a streaked, dusky brown, while her underparts are cream-white, heavily patterned with dark brown vertical teardrop streaks. Like the male, she shares that sharp yellow eye and neat black bill. While she lacks the high-fashion purple cloak, her camouflage allows her to incubate eggs inside tree cavities without turning the nest into a neon beacon for local hawks.

Juveniles: Young birds closely resemble the adult female, sporting brown streaked plumage until young males undergo their first full molt to reveal their regal purple feathers.

Home in the Canopy: Habitat & Geographic Range

The Violet-backed Starling is widely distributed across sub-Saharan Africa, ranging from Senegal in the west across to Ethiopia, and sweeping south down into South Africa. However, you won't find them everywhere on the continent—they explicitly avoid the dense, continuous interior rainforests of the Congo Basin and the bone-dry deserts of southwestern Africa.

They are tree-dwellers through and through. Unlike European Starlings, which spend hours strutting around suburban lawns probing the dirt for leatherjackets, Violet-backed Starlings rarely touch the ground. They prefer elevated perches within:

• Open miombo and acacia woodlands
• Riverine and gallery forests
• Savanna woodland edges and clearings
• Fruiting fig orchards and suburban botanical gardens

Because they are intra-African migrants, their presence in any given location is heavily tied to the seasonal rains and the fruiting cycles of trees. During the dry winter months, populations shift northward or toward coastal river valleys, returning south to breed when the summer rains trigger a explosion of wild fruit and insects. For instance, in southern wildlife havens like Sabi Sabi Private Game Reserve, these birds are celebrated heralds of summer, arriving in small, buzzing flocks just before breeding season kicks off.

Field Notes: Termite Banquets, Dung Architecture, & Canopy Antics

If you manage to sit under a fruiting tree occupied by a flock of these starlings, prepare for a show. Their behavior is fast-paced, social, and constantly acrobatic.

The Ultimate Fruit Snob: Figs are the absolute holy grail for a Violet-backed Starling. They will hang upside down from slender branches like tiny purple parrots to pluck wild figs, mistletoe berries, and mulberries. They ingest the fruit whole, digesting the fleshy pulp and regurgitating or passing the seeds, making them critical seed dispersers for native African trees.

Flycatcher Aspirations: While fruit makes up the bulk of their daily diet, these birds turn into elite aerial combatants when insects emerge. When heavy rains cause alates (winged termites) to swarm by the millions, Violet-backed Starlings drop everything to throw a party. They launch off high dead branches, hawking insects straight out of the air with agile loops and swoops before returning to their perch to swallow their prey whole.

"Watching a flock of twenty male Violet-backed Starlings dive-bomb a flying termite swarm against a storm-grey African sky looks less like foraging and more like a shower of falling sapphires and rubies."

Bizarre Nesting Material: When it comes to real estate, they are secondary cavity nesters. They find old woodpecker holes or natural hollows high up in trees and line them with green leaves, grass, and… fresh animal dung! Yes, really. Researchers believe the inclusion of animal manure in the nest cup serves as an insulating thermal layer and may help deter parasites or mask the scent of the eggs from predators like tree snakes and small raptors. Both parents work together to raise the young, bringing a relentless stream of insects to feed the chicks until they fledge after about three weeks.

How to See One in the Wild (Avery’s Pro Tips)

Planning a trip to sub-Saharan Africa and hoping to tick this jewel off your life list? Don't just scan the grasslands—you need to train your eyes upward. Here is my field strategy for tracking down Cinnyricinclus leucogaster:

1. Follow the Figs: Your single highest probability of seeing a Violet-backed Starling is finding a fruiting wild fig tree (Ficus species) between October and March. If you find a tree heavy with ripe fruit in an open woodland or park, park yourself nearby with your binoculars and wait.
2. Scan the Highest Dead Branches: When males aren't feeding, they love to display from the absolute topmost, leaf-free twigs of tall canopy trees. They do this to maximize sunlight exposure on their iridescent feathers, making themselves as visible as possible to passing females. Look for a small bird silhouette against the sky; if the light catches it and flashes brilliant purple, you've hit the jackpot.
3. Listen for the Whispering Whistle: Unlike their loud, chattering noisy starling cousins, Violet-backed Starlings are relatively soft-spoken. Their song is a pleasant, musical series of warbles, slurs, and soft whistles that often gets lost in the noisy morning choir of the savanna. Check audio databases on Xeno-Canto before your trip to familiarize yourself with their soft calls.
4. Watch for Termite Swarms: If a sudden summer rainstorm hits during late afternoon, keep an eye on the air above tree lines. Starlings, rollers, and bee-eaters will gather en masse to snatch flying termites, offering magnificent low-altitude views.

Whether you're lucky enough to spot one flashing across a South African game reserve or you're just marveling at the sheer physics of their structural purple feathers from your desk, the Violet-backed Starling stands as proof that the bird kingdom holds endless surprises.

Stay curious, stay kind—and if a bird poops on you today, take it as a sign of good luck!
