Red-Billed Quelea – Captive Care of the World’s Most Numerous Bird

Red billed QueleaAlthough attracting less attention than European Starlings and other common birds, Red-Billed Queleas (Quelea quelea) outnumber them all.  Yet despite being dubbed the “Locust Bird” for its habit of moving in flocks containing millions of individuals, this attractive African weaver is surprisingly difficult to breed in captivity.


Population size is not the Red-Billed Quelea’s sole unique characteristic. It is also the only bird in which males exhibit highly variable color patterns that are not designed to advertise their value as mates.  In all other colorful, sexually-dimorphic species (those where males and females differ in appearance), color is used to express desirability to females (please see this Gouldian Finch article).

Some male Red-Billed Queleas vary so much from others that they appear to be of different species. The black or white facial mask is surrounded by feathers that may be colored red, orange, pink or various shades of each; the breast is often splashed with similar colors. Please see the article below for photos of several males…the effect of all this variation in a huge flock must be spectacular!

Ornithologists theorize that this characteristic may aid in individual recognition, but studies have not been conclusive; please see the article below for details.

Natural History

Queleas are classified the Family Ploceidae, which contains 4 sub-families – the True Weavers (Queleas), Buffalo Weavers, Parasitic Whydahs and Sparrows.  Weavers are the avian world’s most accomplished nest-builders.  Largely confined to Africa, weavers use complex knots to create enclosed nests that can only be entered from below. Positioned at the tips of tree branches, these unique nests discourage many predators.

The total Red-Billed Quelea population may approach 10 billion, with some flocks taking 5 hours to pass a single point! Amazingly, these huge aggregations move in a highly-synchronized fashion. Slow motion photography has revealed that the flock feeds in a rolling motion, and in doing so can deplete an area of seeds in short order (the video below pictures the largest gathering of birds ever caught on film).

Queleas prefer wild to cultivated plants, but are still considered to Africa’s leading grain-crop pest. The highly mobile flocks are tracked by agricultural authorities in South Africa and other countries.


The Red-Billed Quelea is found throughout much of Sub-Saharan Africa, but is absent from heavily-forested and extremely arid regions. They are common in several popular wildlife reserves, including Kruger, Amboseli and Selous.


Red billed QueleaQueleas roam widely in search of grass seeds, their primary food, and also remain within flying distance of a water source. They may be found in savannas, thorn scrub, agricultural areas and wooded and marshy grasslands.

Captive Housing

Queleas are always on the move, and, being extremely gregarious, are not at ease unless kept in groups. Consequently, despite being a mere 5 inches in length, they are best suited to life in outdoor aviaries or indoor bird rooms.

Pampas and other stout grasses and shrubs planted in their aviary will make them feel at home and provide foraging opportunities.  Those originating in the southern part of the range (3 subspecies have been identified) adapt well to cool temperatures, but they need shelter from damp and drafty conditions.


A high quality finch seed mix should form the basis of their diet.

Small crickets, mealworms, waxworms and canned and wild-caught insects should be offered year-round, and are a must for pairs with chicks.  In outdoor aviaries, live plants can be used to attract caterpillars, grasshoppers and other tasty treats.

Fresh sprouts and egg food should also be a regular part of your Queleas’ diet.


Weavers construct the most elaborately-woven nests of any bird…watching the construction process was one of the great delights of my time working with birds at the Bronx Zoo. Like most of their relatives, Queleas will use only long blades of green grass as a nesting material. Furthermore, they much prefer stripping these from living plants over picking them off the floor. Taveta Golden Weavers, Red Bishops and others I have kept exploded into action when I placed freshly-dug clumps of beach grass before them, but disdained grass clippings.

Flock of Red billed QueleaRed-Billed Quelea pairs seem to exhibit mate fidelity (although I imagine it’s difficult for researchers – and perhaps the birds themselves – to keep track when 6,000 pairs are utilizing a single nesting tree!). They are stimulated to breed by rain, but also apparently need the company of others if they are to reproduce successfully.

Many other birds also refuse to reproduce unless surrounded by similarly-minded cohorts, a fact that has long thwarted captive breeding efforts.  Some, such as the spectacular Cock-of-the-Rock, are known as “lek-breeders”…several males display together before a female. Spruce Grouse and others battle before waiting females to establish mating rights. Others, such as Queleas and flamingos, seem not to compete, yet will not breed in pairs or, sometimes, even small groups.  I recall West Indian and Chilean Flamingos as being especially “fussy” during the breeding season. Even though I kept them in good-sixed flocks, I and my co-workers had to construct numerous mud nests before they “gave in” and began nesting themselves!

Unfortunately, aviculturists seem not to have hit on the right formula to induce regular breeding in the Red-Billed Quelea…ironic for a species whose flocks are often mistaken for smoke from massive grass fires!

    Amazing. That video was incredible. Of course the passenger pigeon had many billions of birds, including one flock of an estimated 3.5 billion that took 14 hours to pass, and yet in a matter of decades we managed to exterminate them all. It boggles the mind.

    Hello Amy

    Nice to hear from you again…thanks. Yes, both numbers and the extinction re hard to believe!

    Good luck, enjoy and please keep me posted.

    Best regards, Frank Indiviglio.

I believe that I was born with an intense interest in animals, as neither I nor any of my family can recall a time when I was not fascinated by creatures large and small. One might imagine this to be an unfortunate set of circumstances for a person born and raised in the Bronx, but, in actuality, quite the opposite was true. Most importantly, my family encouraged both my interest and the extensive menagerie that sprung from it. My mother and grandmother somehow found ways to cope with the skunks, flying squirrels, octopus, caimans and countless other odd creatures that routinely arrived un-announced at our front door. Assisting in hand-feeding hatchling praying mantises and in eradicating hoards of mosquitoes (I once thought I had discovered “fresh-water brine shrimp” and stocked my tanks with thousands of mosquito larvae!) became second nature to them. My mother went on to become a serious naturalist, and has helped thousands learn about wildlife in her 16 years as a volunteer at the Bronx Zoo. My grandfather actively conspired in my zoo-buildings efforts, regularly appearing with chipmunks, boa constrictors, turtles rescued from the Fulton Fish Market and, especially, unusual marine creatures. It was his passion for seahorses that led me to write a book about them years later. Thank you very much, for a complete biography of my experience click here.
