Atlasing Tales – East of Delmas

Atlasing?  Simply put, it is the regular mapping of bird species in a specific area  called a “pentad”. Each pentad has a unique number based on its geographical position according to a 5 minute x 5 minute grid of co-ordinates of latitude and longitude, which translates into a square of our planet roughly 8 x 8 kms in extent.

As a registered observer / Citizen scientist under the SABAP2 program (SA Bird Atlas Project 2), most of my birding includes recording the species I see or hear, for submission to the project database at the ADU (Animal Demography Unit) based in Cape Town. These tales record some of the more memorable experiences while atlasing.

Delmas is a busy town, known for many years as a centre of large farming operations and now also on the fringe of the coal mining belt that stretches across a large part of the Mpumulanga province and feeds the several large coal-fired power stations in the area. The habitat varies between stretches of prime grassland – lush and long after the good summer rains, large farming operations with tall green mielies (corn) bordering the gravel road for kilometres at a time and, sadly for the environment, areas that have been substantially altered (even devastated) by extensive strip coal-mining activities. The latter is cause for concern as you can’t help wondering if the mine-owners will go to the expense of properly rehabilitating the landscape, once they have stripped out all the available coal. Yes, there are regulations and laws that oblige them to do so, but as with so many things in our beloved country, these laws are often ignored by unscrupulous people who, it is rumoured, buy their way out of their obligations.

The atlasing

The atlasing reminded me once again why atlasing is such a joy (despite my comments about coal-mining) – this outing had all the elements that make atlasing memorable – interesting birding, a handful of “wow” birds seen, pleasant weather conditions, mostly quiet roads and an unexpected surprise sighting.

As usual I was on my way before sunrise and made Delmas in good time before traffic had built up too much. At one spot the low mist combined with the soft light of dawn made for a magic scene which I just had to stop and snap with my iPhone.

Right on 6.30 am I was into pentad 2605_2850 and my list grew apace with all the usual grassland species on view. Orange River Francolin and Swainson’s Spurfowl were particularly vocal, as they often are early morning.

The long grass, stretching as far as the eye could see in places, was dotted with Widowbirds – Long-tailed Widowbirds displaying in their trademark undulating fashion with long tails floating behind them, White-winged Widowbirds fluttering about and Fantailed Widowbirds perched elegantly on longer stalks. Here and there Yellow-crowned Bishops provided a splash of colour in the waving grass.

The road itself was full of action – Doves and Sparrows in abundance and numbers of Red-capped Larks foraging for goodness knows what in the middle of the gravel road (I always wonder why they spend so much time in the road – there can’t be much for them to feed on).

A Marsh Owl over the grassland was cause for the first “wow” of the day, followed shortly after by a Pipit which caught my eye at the roadside – after much deliberation at home and consultation of the wonderful LBJ’s book of Faansie Peacock, I decided it was a Buffy Pipit.

A stop at the Wilgespruit (stream) added African Reed Warbler calling vigorously and out of the many Swallows overhead I could ID White-throated and SA Cliff Swallows. A long stretch of mielies followed, the stalks higher than my Prado – so pleasing to the eye and soul, but not particularly good for birding.

Shortly after I was into coal-mining area where a Black-chested Snake-Eagle surveyed the altered landscape with what I imagined was disdain, but a group of a hundred or so Brown-throated Martins didn’t seem to mind as they were foraging actively amongst the spoil heaps.

With my total on a pleasing 55 species, I turned around and drove back along the same road towards Delmas and the second target pentad for the day.

This turned out to be a rather trying pentad, as it largely covered landscape seriously altered by extensive coal-mining activities and I struggled to find an accessible side road to escape from the incessant string of coal trucks rumbling by every time I stopped.

After 40 minutes of less than happy birding, I abandoned the pentad – nevertheless with 21 species logged, including one “wow” bird in the form of a soaring Booted Eagle, for which I received an ORF (Out of Range form to be completed and submitted whenever a species outside of its normal known range is recorded).

With some time in hand and wanting to make the most of the morning’s atlasing I took the longer way home via the R42 to Bronkhorstspruit.  As I passed the signpost indicating the entrance to Bronkhorstspruit Dam, I decided to explore it and turned off onto a pleasantly quiet stretch of road through grassland. Not far down the road was a bridge over a stream which was just the spot I was hoping for to enjoy some refreshments and view the bird life.

And the birds were plentiful – several Amur Falcons perched on the fence, White-throated Swallows and Brown-throated Martins swooping under and over the bridge, Calling African Reed and Lesser Swamp Warblers, a Giant Kingfisher and a Common Sandpiper bobbing its head on a brick retaining wall while it watched the rushing water below.

Bird of the day was a Half-collared Kingfisher which unfortunately did not hang around long enough for me to get a photo. But a very pleasant conclusion to a mixed day of atlasing.

Surprise Sighting

The surprise of the day was not a bird – travelling along a stretch of gravel road, I spotted a mongoose in the middle of the road, not too unusual when birding in the country areas, but as I got closer I realised it was tackling a snake. The metre-long Mole Snake had coiled itself up for protection, while the Slender Mongoose looked for a vulnerable spot to attack.

My approach disturbed it enough to abandon the snake, which uncoiled itself and headed towards my vehicle.

I reversed out of the way and as luck would have it, at  that moment a car approached from the opposite direction, forcing me to move away to avoid having the snake run over. However the other driver did not appear to see the snake and probably just caught it with a wheel – immediately after the car had passed, the mongoose dashed from its cover, grabbed the injured snake and dragged it into the roadside bush, where it eyed me for a moment before disappearing. A real natural drama on a small scale! Now I believe those stories of Mongoose taking on snakes larger than themselves!

  1. Very interesting, Donald! You are so lucky to live so near the area! Not long until Sheila arrives; you’re going to have lots of fun and see lots of animals – I envy you! I am going to the Serengeti in October, by way of a small inheritance from a dear friend! Can’t wait!
