Across the vast landscapes of Etosha National Park and neighbouring Onguma Nature Reserve, wildlife sightings tend to focus on the obvious. Elephants striding across the pan, lions sleeping beneath camel thorn trees, or a distant rhino moving through the dust. Yet some of the most absorbing wildlife encounters happen much closer to eye level, in the branches of the thorn trees where masked weavers go quietly about their work.
The Masked Weavers of Etosha
Among the most frequently seen species in this part of Namibia are the southern masked weaver (Ploceus velatus) and the lesser masked weaver (Ploceus intermedius). During the summer rainfall season, often referred to as the Green Season, the males take on their striking breeding colours: bright golden-yellow plumage set off by a sharply defined black mask. It is nature’s signal that nesting season has begun. Often choosing thorny bushes and the branches of trees scattered across the reserve as nesting sites, these soon become a hive of activity.
When is the best time to see masked weavers in Etosha?
The peak nesting season runs from December to February during the summer Green Season, when rainfall, grass growth and insect abundance all align. This is when colonies are most active and easiest to observe on game drives.
What do masked weavers eat?
Adult masked weavers feed primarily on seeds and insects. During the breeding season, insects become especially important as a protein source for growing chicks, and parents make repeated trips to the nest to deliver food.
How long does it take a weaver to build a nest?
A male southern masked weaver can complete a nest in as little as one to two days, weaving hundreds of individual grass strands into a tightly structured chamber. If the nest is rejected by a female, he will dismantle it and begin again.
How do I tell a southern masked weaver from a lesser masked weaver?
The most reliable field mark is the eye. The southern masked weaver has a distinctive red eye, while the lesser masked weaver’s eye is pale or yellowish. The lesser masked weaver’s black mask also tends to be slightly less extensive. Both species are found at Onguma, often in the same areas.
Are masked weavers found only in Etosha?
No. Both species have a wide distribution across southern and eastern Africa. However, Etosha and the surrounding reserves such as Onguma offer particularly good conditions for observing them due to the abundance of seasonal grasses, water sources and open woodland.
Southern Masked Weaver vs Lesser Masked Weaver: Key Differences
While both species are common in and around Etosha, there are a few reliable ways to tell them apart in the field. The southern masked weaver (Ploceus velatus) is the more widespread of the two and is distinguished by its red eye, which contrasts sharply with the black mask. The lesser masked weaver (Ploceus intermedius) tends to have a pale or yellowish eye and a slightly less extensive black mask that does not reach as far down the throat. In terms of habitat, the lesser masked weaver often favours areas with slightly denser vegetation and reliable access to water, while the southern masked weaver is more adaptable and can be found across a wider range of habitats. Both species are colonial nesters, but lesser masked weaver colonies can become especially active after good summer rains, when grasses grow tall and insect life flourishes.
Nature’s Master Nest Builders
For travellers on early morning game drives through Etosha National Park and Onguma Nature Reserve, the evidence is easy to spot. Hanging from the outermost branches of trees are dozens of neatly woven nests, each shaped like a small lantern swaying gently in the breeze. These structures are crafted from strips of fresh green grass, woven with remarkable precision into tight, rounded chambers with a downward-facing entrance. The design helps deter predators while also protecting eggs and chicks from the harsh Namibian sun.
The southern masked weaver is particularly industrious. A single male may construct several nests during the breeding season, weaving strand after strand of grass with astonishing speed. Once a nest is complete, he hangs beneath it, wings fluttering, calling loudly to attract a passing female. If she approves, the focus shifts from display to quiet, methodical care. If she does not approve, the nest will likely be destroyed and the male will begin the entire process again.
Once a nest has been accepted, the female lines the interior with softer grasses and plant fibres, creating a secure chamber for the eggs. A typical clutch consists of two to four pale eggs, incubated primarily by the female over a period of around 12 to 14 days. During this time, the male may remain nearby, maintaining his territory and continuing to display at neighbouring nests. Once hatched, the chicks are fed a protein-rich diet of insects, an essential resource during the growing season, delivered in a constant shuttle of movement between branch and nest. The enclosed structure offers protection from predators and the elements, but the nest remains a busy, vulnerable space, with both parents alert to threats. Within a few weeks, the chicks are ready to leave the nest, making their first uncertain flights into the surrounding thornveld, while the colony carries on around them, as busy as ever.
With over 20 years of guiding experience, a decade of it spent at Onguma, Viktor has an easy familiarity with these moments that many guests overlook entirely. On a drive he will point out the vivid green of a newly woven nest beside the faded, weathered tones of an older one, or draw attention to the tell-tale movement of a female inspecting a potential home. These are the quieter moments of a game drive, easily overshadowed by larger wildlife sightings, yet no less compelling when you know where to look.
The lesser masked weaver, while similar in appearance, often favours areas with slightly denser vegetation and access to water. As Viktor explains, after good summer rains the air carries a constant soundtrack of chirps and calls as birds arrive with nesting material, defend territories and tend to their young. It is a whole world of quiet activity playing out just above eye level, one that rewards the patient observer.
Small Birds with a Big Role in the Ecosystem
Beyond their visual charm, masked weavers offer valuable insight into the health of the ecosystem. Their breeding success depends on healthy grasslands for nest-building material and a steady supply of insects to feed their chicks. Where the habitat is thriving, the colonies are busy, offering a visual clue to the importance of conservation.
For those who take the time to look, the masked weavers add another dimension to the Etosha experience. In a landscape defined by extremes of heat, drought and sudden rain, these small birds continue to weave homes from grass and instinct, quietly stitching new life into the branches around them and reminding visitors that the wilderness is sustained as much by its smallest architects as by the larger animals that call the region home.
When Is the Best Time to See Masked Weavers at Onguma?
The best time to observe masked weavers at Onguma is during the Green Season, which typically runs from November through to April. This is when the summer rains arrive, grasses grow tall, and insect populations peak, providing everything the birds need to breed successfully. Nesting activity is at its height between December and February, when colonies are at their most vocal and the sight of dozens of males simultaneously weaving, displaying and competing for female attention is one of the more extraordinary spectacles the reserve has to offer. Game drives during this period frequently pass active weaver colonies, and guides like Viktor are well-versed in explaining what you are seeing and why it matters.
