The Swartkops Estuary in Port Elizabeth is well-known as one of South Africa’s 112 Important Bird & Biodiversity Areas (IBAs) and while the river and mudflats have the greatest density of birds and hog the limelight as the most natural areas, my sunset visit on December 30 was to the salt pans and threw up a special that is often difficult to find elsewhere.

The Chatty River flows from the west into the Swartkops River and alongside it, next to the R367 main road, there are commercial saltpans which can provide quality foraging opportunities for many birds, especially when the salinity and water level are just right for a host of invertebrates to be crawling around in the benthos.

The elegant flamingos – both Greater and Lesser – immediately catch the eye and I was also drawn to the Pied Avocets, one of my favourite birds, sweeping and scything around in the water.

But dotted around the pan were smaller birds – the Blacknecked Grebe.

The Chatty Saltpans hold globally significant numbers of this uncommon nomad, which has the propensity to suddenly colonise a flooded area and start breeding. There are usually good numbers of this cute little diving bird at Swartkops though, and I did not notice any birds in breeding plumage, so perhaps they were moulting, with the widely-distributed Blacknecked Grebe known to utilise saline lakes overseas for this purpose.

Another special that can be picked up at the Swartkops Estuary is the Hartlaub’s Gull, which has a recently-established breeding colony in the area. It was previously considered a bird of the Western Cape, its distribution tied to that of Kelp, with only vagrant birds moving east of Cape Agulhas, and it interbreeds with Greyheaded Gulls in this river valley. Being omnivorous, it seems to have adapted to new foraging opportunities around human settlements.

Nicely built-up embankments between the pans allow one to approach the vulnerable Flamingos and their friends reasonably closely as they continue their search for invertebrates, and other birds that have adapted well to man-made wetlands were also busy foraging for their dinner in the gathering gloom – Blackwinged Stilt, African Spoonbill, Cape Cormorant, Kelp Gull, Egyptian Goose, Blacksmith Plover, Cape Wagtail and Sacred Ibis.

The Marievale Bird Sanctuary is a Ramsar-site whose vast reedbeds and multitude of open pools are home to thousands of waterbirds.

Perhaps the most regal of its denizens is the African Marsh Harrier, an uncommon raptor that spends most of the day gliding over the pools and reedbeds on the hunt for rodents and other tidbits.

The African Marsh Harrier spends half of its day in the air and it likes to get an early start, so there it was as the sun was rising on Human Rights Day setting off on the breakfast run as it quartered low over the reedbeds.

My wife and I had a fine view of this long-winged beauty as we sat with our morning tea on the balcony of our little chalet overlooking the wetland. Blackcrowned Night Heron, Grey Heron, Greyheaded Gull, Redknobbed Coot, Cape Shoveler, Whitewinged Tern, Whitebreasted Cormorant, Cattle Egret, Spurwinged Goose, Greater Flamingo and Glossy Ibis were all easily spotted from our chalet on the edge of the water.

Soon we were on our way, heading for the causeway over the Blesbokspruit. This tarred section is a wonderful spot because there are pools of water close-by on both sides of the road, as well as vegetation right up to the causeway.

On the way there, Redshouldered and Longtailed Widows were busy in the grasslands, Southern Masked Weavers were almost ubiquitous and the sexually dimorphic Amur Falcons were dotted along the power and telephone lines along the road.

A lone Swainson’s Francolin was out and about in the brisk morning air – 15° was the temperature for most of the day – and popping into the Hadeda Hide en route produced Little Egret and Reed Cormorant.

Both Yellow and Blackthroated Canary were enjoying the seeds of the many Docks (Rumex spp) along the road, before we turned west on to the causeway and the waterbirds came thick and fast.

Common Moorhen were swimming around the pools, Pied Kingfisher were hovering and diving for breakfast, Cape Reed Warblers were singing merrily as they worked their way through the reeds, African Jacana were standing stately on the lilypads and Whitethroated Swallow, along with Brownthroated Martin, were zooming about.

Purple Gallinule and Malachite Kingfisher were also around and, as we exited the car and walked towards the Otter Hide, a sleek, sinuous dark head rose from the water – it could have been considered reptilian except it had whiskers, and a little black nose and eyes – a Spottednecked Otter just where it should be!

A handsome Hottentot Teal was also swimming around and Black Crake and African Darter were spotted too.

The open waters between the causeway and the picnic site also produced Redbilled Teal and Dabchick.

The northern section of Marievale takes you through productive wetlands on your left and open grassland on your right. Here Blackshouldered Kite and Hadeda Ibis were on one side of the car, while Squacco Heron, Little Bittern and Whiskered Tern flew around on the other.

Great Crested Grebe were swimming on the large expanse of water in front of the Duiker Hide, while the Flamingo Hide, back by the picnic site, also has a wide vista of open water and reedbeds in front of it. Large flocks of European Swallow are found here, but there were also Blackwinged Stilt and a rather tame African Reed Warbler, who was at much closer quarters.

Popping into the Hadeda Hide again on our way back to our chalet yielded the archetypal wetland Cisticola, the Levaillant’s. From regal raptors to skulking little LBJs, Marievale Bird Sanctuary has it all.
