Black-winged kite (Elanus caeruleus) photographed in flight above the Diep River at Woodbridge Island in 2024, after approaching from the Milnerton Golf Course direction. Captured with a Canon EOS 7D Mark II and EF 400mm f/5.6L USM lens.
First-hand field observation: This Black-Winged kite was photographed by Vernon Chalmers above the Diep River at Woodbridge Island in 2024 using a Canon EOS 7D Mark II with an EF 400mm f/5.6L USM lens. The observation records the bird approaching from the Milnerton Golf Course direction and continuing inland. It forms part of an ongoing personal photographic record of raptor activity around the Woodbridge Island–Diep River landscape.
Another Raptor Observation at Woodbridge Island
There are bird photographs that record a moment, and there are photographs that become part of a much larger observation record. My 2024 photograph of a Black-winged kite over the Diep River at Woodbridge Island has increasingly become the latter.
At the time, my primary interest was simply to photograph the bird successfully in flight. Looking back at the image now, however, the sighting has additional significance because it fits into an emerging pattern of raptor observations around the Woodbridge Island and Milnerton landscape.
The bird was photographed above the Diep River after I had observed it flying from the direction of the Milnerton Golf Course, on the inland side of the landscape. It was continuing inland when I managed to acquire and photograph it. The observation therefore provides more than a species identification: it records a particular bird, at a particular location, travelling in a particular direction through the landscape.
Key Sighting Details & Behavior
- Location: Often observed hunting high above the Woodbridge Island bridge / Table Bay Nature Reserve area, the lower Diep River channels, and adjacent wetlands.
- Hunting Style: This compact raptor is famously seen hovering motionlessly in mid-air on upturned wings roughly 10 to 50 meters up before dropping directly down onto small rodents or insects in the grass or reed margins.
- Appearance: Striking pale grey and white plumage with distinct black shoulder patches, bright red eyes in adults, and sharp black-and-white wing contrasts in flight.
- Context: Documented in local birding logs for the Milnerton/Table Bay area (such as records compiled via the Cape Bird Club Site Guide) alongside other raptors like the African Marsh Harrier and African Fish Eagle.
A Black-Winged Kite in Flight
The photographs shows the bird in powerful but relatively controlled flight postures, with its wings extended and the distinctive black-and-grey patterning clearly visible.
The species is Elanus caeruleus. Current BirdLife South Africa nomenclature lists it as the Black-winged kite, with the species characterised by grey upperparts, white underparts, black shoulder patches and red eyes. (BirdLife South Africa)
BirdLife South Africa's current checklist uses Black-winged kite, while older South African material and other publications have used Black-shouldered Kite. (BirdLife South Africa)
The scientific name provides the stable reference: Elanus caeruleus.

The Woodbridge Island Observation
What interests me most about this photograph today is not simply the bird itself.
The observation took place above the Diep River, within the broader Woodbridge Island landscape. I had seen the bird approaching from the direction of the Milnerton Golf Course, and it was flying inland when I photographed it.
That direction is significant because I have subsequently begun paying much closer attention to the movement of raptors through this landscape.
At the time of the original photograph, I did not regard individual raptor sightings as particularly important for building a longer-term body of content. They were relatively uncommon observations, and a single photograph could easily be treated simply as another successful bird-in-flight image.
That perspective has changed.
As more observations have accumulated, the geographical context has become increasingly interesting.
The Black-shouldered Kite is therefore not being presented here as evidence of a defined migration route. One observation cannot establish that. Nor can the direction of one flight demonstrate a regular movement pattern.
What it does establish is much simpler and more useful:
A Black-winged kite was observed travelling inland over the Diep River after approaching from the Milnerton Golf Course direction in 2024.
That is an empirical observation that can be retained and compared with future observations.

A Species Associated With Open Habitats
The ecology of the Black-winged Kite also makes the location interesting.
BirdLife South Africa describes the species as occurring widely across South Africa, particularly in open habitats. Its preferred environments include grassland, savanna, shrubland and agricultural areas, while its diet consists primarily of rodents, supplemented by small birds, reptiles and larger insects. It commonly hunts from a perch or by hovering. (BirdLife South Africa)
The broader Woodbridge Island landscape contains a mixture of habitat types that are quite different from what might initially be imagined when looking at an urban Cape Town environment. The Diep River, golf-course landscape, open areas, wetlands and surrounding built environment form a mosaic rather than a single uniform habitat.
That makes the movement of raptors through the area worth observing.
The golf course and surrounding open areas can provide opportunities for hunting, while the river and adjoining open spaces form another component of the landscape through which birds can move.
I am careful, however, not to infer why this particular kite was flying in this direction. The photograph tells me where the bird was and the direction in which it was travelling. It does not tell me whether it was hunting, commuting between areas, responding to prey availability, or simply moving through the area.
That distinction between observation and interpretation is important.

The Emerging Raptor Record
This photograph has become more significant because it is now possible to place it alongside several other raptor observations from the same general landscape.
There is the Yellow-billed Kite photographed on 26 February 2026 during my first field test of the Canon EOS R6 Mark III with the RF 800mm F11 IS STM. That bird also appeared from the Table Bay direction and followed a flight path that subsequently became interesting in relation to another observation.
There is the juvenile Black Sparrowhawk, my first recorded sighting of that species in this particular context, again associated with a similar flight corridor.
There are also the Jackal Buzzard observations from my earlier photographic archive, providing another raptor record from a different period.
And now there is this 2024 Black-shouldered Kite.
These should not be collapsed into a claim that all four species are following the same route. They are different species with different ecological requirements, and the observations were made at different times.
The more cautious and potentially more valuable interpretation is that the Woodbridge Island–Diep River–Milnerton landscape appears to be a place through which a variety of raptors can be observed moving.
That is something worth documenting over time.
From Bird Photography to Landscape Observation
This has changed the way I think about some of my older photographs.
When I photographed the Black-winged Kite in 2024, the image was primarily a bird-in-flight photograph. The technical challenge was to acquire the bird against the sky and maintain focus while it crossed the frame.
The equipment was the Canon EOS 7D Mark II with the EF 400mm f/5.6L USM.
The combination remains particularly appropriate for this kind of observational photography. The 400mm focal length provides substantial reach while retaining enough field of view to acquire a relatively fast-moving bird. The 7D Mark II's APS-C sensor also gives the lens an effective field of view equivalent to approximately 640mm on full-frame.
But the technical photograph is only one layer of the record.
The second layer is geographical: where was the bird?
The third is behavioural: what was it doing?
The fourth is directional: where was it coming from and where was it going?
And the fifth emerges only over time: does this observation connect with other observations from the same landscape?
That last question is what I am increasingly interested in.
Building the Observation Record
One of the advantages of maintaining a long-running photographic archive is that observations that seemed relatively insignificant at the time can acquire new meaning later.
A single raptor sighting may tell me very little.
Several sightings, recorded over several years, from approximately the same landscape, begin to provide something different.
They do not automatically prove a biological pattern. But they create a photographic observation dataset that can be revisited, compared and expanded.
This is particularly relevant to my developing approach to photography around Woodbridge Island.
I am increasingly interested in recording not only what I photograph, but also when, where, from which direction, and under what circumstances the subject was observed.
That transforms the photograph from an isolated image into a piece of field documentation.
The Black-shouldered Kite therefore occupies an interesting position in this developing record. It is a 2024 observation, made with an entirely different camera system from the more recent R6 Mark III observations, but the location and flight direction provide a potentially useful point of comparison.
Future sightings may add further evidence.
They may also show that the apparent pattern was simply a consequence of chance observations.
Both outcomes are valuable.
Looking Back at the Photograph
Seen today, the photograph has another quality that I appreciate more than I did when I made it.
The bird is completely separated from the background by the clear blue sky. The extended wings reveal the structure of the flight feathers, while the black shoulder and wing markings contrast strongly with the pale body. The red eye is also clearly visible.
Technically, it is a successful bird-in-flight photograph.
Documentarily, however, it is more than that.
It records a Black-shouldered Kite over the Diep River in 2024, travelling inland after approaching from the Milnerton Golf Course direction.
That is the information I want to preserve.
An Observation Worth Revisiting
My earlier approach was to regard rare raptor sightings as isolated events because they happened infrequently.
The developing Woodbridge Island record has changed that perspective.
The Black-shouldered Kite, Yellow-billed Kite, Black Sparrowhawk and Jackal Buzzard observations now provide several separate points from which to examine raptor activity in this landscape. Each species should remain documented independently, without forcing them into a pattern that the evidence cannot yet support.
But the observations can also be connected.
That is where the value lies.
Over time, repeated observation may reveal whether these sightings represent nothing more than occasional encounters or whether the geography of the Woodbridge Island and Diep River environment is contributing to a recurring movement corridor for different raptors.
For now, the appropriate response is simply to keep watching.
Observe the bird. Record the location. Note the direction. Photograph it when possible. Preserve the date and equipment information. Then compare the observation with what came before.
That is how an individual photograph can gradually become part of a much larger record of the landscape.
Source note
BirdLife South Africa's current taxonomy and checklist use Black-winged Kite (Elanus caeruleus). Its 2025 Red Data Book assessment places the species in the Near Threatened regional category and notes a significant decline in reporting probability in SABAP2 data. That conservation information is separate from my individual Woodbridge Island observation and is not being used to infer anything about the local population from this photograph.
