Welcome to Bad at Goodbyes.

On today’s show we consider the White-winged Flufftail.

The White-winged Flufftail is a critically endangered avian, a bird, native to Africa, specifically Ethiopia and South Africa. Its scientific name is Sarothrura ayresi.

The White-winged Flufftail is small bird, measuring roughly five and half inches beak tip to tailfeather with a wingspan of about nine inches and weighing roughly one ounce.

Their plumage is a warm reddish brown on their head, breast, upper back and tailfeathers. The lower back and wings are black, marked with white spots and lines. And their belly and their secondary flight feathers (revealed only when the wings are spread) are white; which gives the White-winged Flufftail part of its name. The other part, the flufftail part, describes the species’ tailfeathers which are short and have a soft, downy, fluffy appearance. This characteristic is more more pronounced in other species in their genus, like the Red-chested Flufftail or the Madagascar Flufftail but in general flufftails have a kind of cottonball poof at their rear.

So between that and their contrasting range of plumage and markings, the White-winged Flufftail has a very textured and complex appearance, a camouflage in its native habitat, that reflects its primarily ground dwelling behavior.

The White-winged Flufftail is considered terrestrial, meaning that it spends most of its time on the ground, hidden within dense vegetation, in reeds and grasses, primarily walking, slowly, stealthy, avoiding detection. When threatened it will briefly take flight but only a few feet in the air, only for a few dozen yards before diving back into the brush cover.

It is elusive, secretive, relying on stealth and avoidance as a defense from likely aerial predators like Harriers and Hawks.

Relatedly it is [Kruh-puh-sk-cure-lure] crepuscular meaning that it is active primarily during the twilight at dusk and dawn. Only forging and calling, in low light, spending the daylight and moonlit hours hidden away.

It is a solitary bird, generally observed alone, or in mating pairs, it does not flock or congregate in groups and motion sensor cameras have observed intraspecies and interspecies territorial behavior. Males will flash their white wing patches, charge and make hissing sounds at both other members of their species and at small birds of other species in defense of their territory. An individual’s or mating pair’s territory is roughly 8 acres. And all day-to-day activities (roosting, mating, feeding) take place in these relatively small densely vegetated plots.

The White-winged Flufftail is omnivorous, feeding on beetles, moths, flies, spiders, and small crustaceans, as well as grain seeds and plant shoots. The Flufftail forages from the safety of dense cover in microhabitats where its prey is likely to be concentrated; soft muds and in shallow water, plucking prey directly from the ground, from plant stems, and from the water.

In the dream,

With anticipation of the twilight, a softening of contrasts, an easing of intensities

Here in the hours between sun and moon, or moon and sun, interim, liminal.

In that time between times, to live most fully.

to celebrate in blurred light, under purpled skies,

sharing the bright stitchings beneath our dark cloak, calling to our love among the reeds.

Here in this brevity, where the veil is thin,

We feast, we sing, we stretch our wings.

In the dream.

The White-winged Flufftail forms monogamous pairs to mate, though we do not know whether these pairs persist across mating seasons. Mating season is the summer rainy season, and camera traps have captured some courtship behaviour, specifically a distinct short flight wing-flapping, performed by both males and females, in which their white secondary flight feathers are prominently displayed, a kind of attention-grabbing demonstration of their suitability as potential mates.

Once a pair bond forms and mates a nest is constructed, on the ground, in dense vegetation with a preference for areas of tall, mixed sedges in shallow water. Both parents incubate the 3-5 eggs and defend the nest for roughly 2-3 weeks and then the chicks hatch precocial, meaning they are born relatively well-developed and are quickly mobile, able to leave the nest and begin walking soon after birth. Shortly after they emerge from the nest, the parents shepherd the chicks to areas of even denser vegetation and deeper water, for protection.

We do not know how long the chicks remain in parental care, but they reach reproductive maturity in about a year. Individuals can live up to 10 years old.

We find both populations in high-altitude marshlands, in Ethiopia, in highlands near Addis Abba, and in South Africa in the provinces of the Eastern Cape, Mpumalanga, [kwaa-ZOO-loo-nuh-TAL] KwaZulu-Natal, and the Free State.

In Ethiopia, their habitat is roughly a mile above sea level and in South Africa ranges from roughly one half to one mile in elevation. In both locations, we find shallow, slow-flowing water, and peaty soils. Peat is a kind of soil formed in water-saturated environments where plant material only partially decomposes, so the soil has high organic matter content, is acidic, and holds moisture.

Within these marshlands, the White-winged Flufftail prefers specific water depths, between 1-10 inches and is not found in areas that are either too dry or too deeply flooded. And they prefer very dense vegetation coverage: sedges, tall watergrasses, and reeds, ranging from 1-3 feet in height.

In both locations, summer highs average in the mid to upper 80s°F and winter lows in the mid-50s°F. And both regions see between 25-30 inches of precipitation per year.

The White-winged Flufftail shares its habitat with:

Common Reed, African Marsh Harrier, Southern Cutgrass, Slender Knotweed, Denham's Bustard, Blue Crane, Vlei Rat, Jersey Cudweed, African Grass Owl, Southern Oribi, Black Stork, Yellow-breasted Pipit, Rudd's Lark, Pale Smartweed, Lesser Kestrel, Plain Ragwort, Southern Bald Ibis, Nepal Reedgrass, Secretarybird, Cape Vulture, Rough-haired Golden Mole, Common Crane, Spot-breasted Lapwing, Robust Golden Mole, Lesser Pond-Sedge, Orange Amber Butterfly and many many more.

Population threats

The White-winged Flufftail’s population has been dramatically reduced by anthropogenic activity, that’s human-caused. In both Ethiopia and South Africa, habitat loss and degradation is the primary threat.

In Ethiopia, this is the conversion of wetlands for agriculture, overgrazing by domesticated livestock, and mowing of wetland vegetation for livestock feed. The White-winged Flufftail is a ground-dweller that relies on dense grasses, so nest-trampling by livestock and habitat conversion is an existential risk. Currently, in Ethiopia, more than 90% of the wetland habitat suitable for the Flufftail has been completely altered or lost.

In South Africa, similarly, habitat conversion for agriculture and overgrazing threatens the species. Additionally infrastructure projects like the construction of roads and dams are changing and fragmenting the Flufftail’s home. And development by the mining industry, both degrades the landscape and pollutes waterways.

Lastly, human induced climate change is a longterm threat. In both Ethiopia and South Africa, climate models predict an increase in the frequency and severity of extreme weather, likely leading to severe drought, causing the shallow wetlands to dry out, rendering them uninhabitable. And also more flood-prone, with intense rains washing out nests and leading to water levels that are too deep for the bird to forage.

Fortunately, the White-winged Flufftail is legally protected internationally and in Ethiopia and South Africa.

In Ethiopia, sections of its small remaining habitat have been fenced off to prevent disturbance from livestock. In South Africa some portions of its habitat is on protected lands including the Middelpunt Wetland which forms part of the recently declared Greater Lakenvlei Protected Environment, and the nearby Verloren Valei Nature Reserve, which are both in the Mpumalanga Province.

There are Habitat Management and Restoration projects in place to preserve and improve remaining habitat, including wetland rehabilitation projects, and community patrols of breeding areas to prevent unsustainable grass cutting, and overgrazing.

Recent scientific research uncovered a previously unknown population in South Africa, and studies of the species and concerted conservation attention is ongoing.

I honor the lifeforce of the White-winged Flufftail. I will commit its name to my record. I am grateful to have shared time on our planet with this being. I lament the ways in which I and my species have harmed and diminished this species. I grieve.

And so, in the name of the White-winged Flufftail I pledge to reduce my consumption. And my carbon footprint. And curb my wastefulness. I pledge to acknowledge and attempt to address the costs of my actions and inactions. And I pledge to resist the harm of plant and animal kin and their habitat, by individuals, corporations, and governments.

I forever pledge my song to the witness and memory of all life, to a broad celebration of biodiversity, and to the total liberation of all beings.
