The Brown-headed Parrot (Poicephalus cryptoxanthus) is, I suspect, one of the more under-appreciated birds we see, mostly due to the fleeting sightings we have of them. Often seen as a flash of green darting across the sky with its characteristic call, their presence is short-lived and gone before you know it. Until the other day, on morning drive, when we came across two parrots in a dead knobthorn ahead of us, which overhung the road. The pair of them seemed unusually relaxed, and so we switched off the vehicle and watched them for some time.

But there is so much more to this bird than its modest appearance suggests — a story stretching back millions of years, written in feathers, tree cavities, and a remarkable commitment to partnership.

A Name That Hides a Secret

Let us start with the name itself, because it is a rather wonderful description of them which I have never appreciated until this day. Cryptoxanthus comes from the Greek: kryptos, meaning hidden, and xanthos, meaning yellow. The “concealed yellow” parrot. At rest, perched among the leaves, this bird looks entirely unremarkable, a medium-sized, stocky green bird with a brown-grey head, a pale hooked beak – the classic ‘parrot’.

Then it takes flight. (or in my case, was cleaning itself).

For a brief moment, you could see the yellow that is unusually concealed under their wing.

The moment the wings open, a blaze of brilliant yellow is revealed on the underwings, but soon lost when it lands or is flying at high speed past you. Due to its fast flight, it’s also hard to notice the flash of yellow as the vibrant green captures your attention more than the yellow.

Life in the Flocks — and Then Something More Intimate

For much of the year, Brown-headed Parrots are gregarious and social, moving about in small groups of around ten to twelve birds, and congregating in flocks of up to fifty where food is abundant. They are noisy and opinionated travellers, announcing themselves with loud, strident calls that rise in pitch with each note, a sound that carries far across the bushveld, unmistakable once you have learned it. Between calls, foraging flocks chatter softly to one another, an almost continuous low conversation as they work through the fig trees, acacias, cassias, marulas, and knob-thorns that form most of their diet.

But as the breeding season approaches — from around April- May — something shifts. The flocks dissolve. Pairs quietly peel away from the group, and what remains are two birds, moving and foraging closely together.

Brown-headed Parrots are, in fact, monogamous — and not only during the breeding season. Research has shown that while the large summer feeding flocks might suggest fleeting pair bonds, these birds actually maintain lasting partnerships year-round. The flock is social camouflage; the pair bond is the constant. It is a reminder that the most important relationships in the wild are often the quietest ones.

Courtship: Tenderness in the Treetops

Courtship in Brown-headed Parrots is through proximity and touch, through mutual preening, where one bird carefully tends to the feathers of its partner’s head and neck, reaching the places that cannot be reached alone. They share food. The male feeds the female, passing food from his bill to hers.

The Nest: Borrowed and Precious

When it comes to nesting, Brown-headed Parrots are known as secondary cavity nesters. They do not excavate their own holes. Instead, they inherit them — tree cavities worn open by time and weather, or the old nest holes of woodpeckers, abandoned and waiting. This dependency on existing cavities means that large, old trees are not merely scenery in their world; they are essential infrastructure. A mature marula or fig, hollow-hearted and weather-worn, can be as valuable to a parrot pair as any prime real estate.

The female parrot inspecting the hole cavity

The female selects the cavity and lays a clutch of three to four eggs at the base of the hollow without any lining. The eggs hatch not all at once, but two to four days apart, which means the eldest chick has a head start in size over its younger siblings — a common strategy in cavity-nesters, ensuring that in a good year all chicks may survive, but in a lean year, the strongest are most likely to fledge successfully.

Incubation lasts around 26-30 days, during which the female remains largely in the cavity while the male provisions her with food, that same act of feeding made practical and essential and hence why it is important during the courtship phase. (The female needs to choose a suitable mate that she can depend on to feed her during the incubation process). Once the chicks hatch, both parents share the task of foraging for food independently. But interestingly, both parents have to meet at the nest simultaneously before the male feeds the chicks. Followed by the female regurgitating food to the male, and then he once again feeds the chicks. This is a unique behaviour where, if only one adult is present, the chicks will not be fed. The chicks remain in the cavity for approximately eight to ten weeks before fledging.

A Bird Worth Pausing For

There is a tendency, I think, to let the Brown-headed Parrot slip past unexamined, but consider for a moment the unique life that these birds live. A small creature that forms enduring bonds and tends to its partner with quiet constancy to raise their clutch each year together.

The next time a flash of green catches your eye in the canopy, and you hear that rising, strident call, I hope you will pause for a moment longer. Because sometimes the most extraordinary things in the bush are the small secret lives that they endure
