A couple of weeks ago I posted about a selection of Waders (Shorebirds) and other water birds that I had encountered during an atlasing trip to Bronkhorstspruit Dam Nature Reserve not far from Pretoria.
Well, I wasn’t expecting to visit this nature reserve so soon again, but an alert received this past Saturday from SA Rare Bird News run by Trevor Hardaker (the second item in his alert below) had me reconsidering fairly quickly – a Baird’s Sandpiper would be a lifer for me and, having been spotted just 45 minutes drive from my home in Pretoria, it was an irresistible twitch.
I was not keen to join what I expected to be a twitcher scramble on the Sunday so I waited for Monday morning, when I picked up Koos Pauw at 6.30 am and we headed east along the N4 highway, then took the R25 and R42 turnoffs to take us to the nature reserve access road.
The many twitchers making their way to the dam the previous day combined with heavy overnight rain had turned the gravel access road and the nature reserve tracks into a muddy jumble in places – no problem for my Prado but we felt for the hardy twitchers in small sedans who we saw later in the reserve – no one got stuck while we were there but the road was worse on our way out, so those drivers would have had to use all their skills to get out without a problem.
We couldn’t help chuckling when we saw two Yellow-billed Ducks swimming in one of the larger puddles in the bumpy nature reserve track – how opportunistic, but it left us wondering why they chose a muddy puddle instead of the vast expanse of dam just 50 metres away.
From previous experience of twitches at popular, accessible birding spots such as this, I knew the best way of finding the target rare bird after an alert is to drive to the area where you expect to find it, then look for parked cars – this was my strategy and it worked, but only just!
As we approached the approximate position along the dam edge given in the alert, a vehicle was heading towards us – we stopped to chat and the friendly driver offered to show us “the Baird’s” as they had just come from its location, with no one else around at the time. We accepted with alacrity and a couple of minutes later we were at the right spot and watching the Baird’s Sandpiper ourselves – success! (cue the Beatles “With a little help from my friends”)
We had nevertheless armed ourselves with some knowledge of the species and its main identifying features, in case we were faced with finding and identifying it ourselves – but our newfound friend quickly informed us that we only had to look out for the ‘small wader with a limp’ as it seems it had injured its leg, so the task of picking it out among the other small waders was very simple. The video clip below shows just how pronounced its limp was
Baird’s Sandpiper Calidris bairdii (Bairdse strandloper)
The Baird’s Sandpiper falls into the wader family known as the Calidrids, breeding at Arctic latitudes of Alaska and Canada and usually migrating to South America during the austral summer.
Occasionally, as with this one in all probability, a single bird is blown off course by adverse weather conditions, or its ingrained directional instinct goes slightly awry and they end up in southern Africa instead. Not without an almost unfathomable effort of course, for its journey would have taken it across the Atlantic Ocean at some stage.
Less than 20 records exist of sightings of this species in the southern African region, since 1984 – prior to that there is just one record from 1863! So its status is rightly given as a very rare vagrant
Waders without clear features which set them obviously apart from other similar sized waders can present a real challenge to birders and the Baird’s Sandpiper falls into that category. If it hadn’t had the distinct limp we would have had to resort to looking for the features given in the illustration below from the Roberts app
So that’s how I added the latest lifer to my Southern African list – simple really …….
As with my previous visit we spent the next couple of hours driving slowly as close to the dam shoreline as we could, scanning every metre of it as we went. This paid off with several more good sightings of waders and other birds, many of them the same species as I had recorded before, but with some exciting new additions – more about these in a follow up post
Finally, just a mention of the two outstanding sources that I have used for the information in this post :
Firstly, Roberts VII Multimedia Birds of Southern Africa – the go-to guide for detailed information on all of Southern Africa’s birds
Secondly, the more focused Chamberlain’s Waders – The Definitive Guide to Southern Africa’s Shorebirds by Faansie Peacock (No, that’s not a made up name!)

Your tale gives me gooseflesh! I am not a twitcher by any means, but can understand the excitement and thrill of actually seeing such a very rare bird yourself. What a wonderful opportunity! I hope its leg will heal before long so that it can – perhaps – be on its way once more. Your photographs and video are good to see.
It is easy to become addicted to twitching and rush across the country every time a rarity pops up as many birders do, but I have resisted it so far and only go for those that are reasonably accessible to me wherever we are at the time. Nevertheless it remains a thrill to find and identify birds which unexpectedly arrive in our region
