Article Preview; New Nikkor 70-200mm F4 for Macro Photography

-->
Post and photos by Denni Raubenheimer
       
Its been quite the busy week and I have been unable to write my intended article on Nikon’s great new 70-200mm lens, the AF-S Nikkor 70-200mm 1:4G ED, for use in macro and semi-macro photography. What I am able to do is post this pseudo-preview. The lens boosts top-end optical performance, record-breaking vibration reduction and small minimum focus distance. Here follow two samples taken with the lens on a Nikon D800, though only one of these fall into macro classification.

        Last week I was fortunate to have an early weekday morning open to do some wildlife photography. I had planned to visit Roodeplaat Dam Nature Reserve for a mix of photography and bird-watching. However, with economic crunches and an income that fluctuates from month-to-month I decided to rather opt for Fearie Glen Nature Reserve, which is much closer to our home. My disappointment at not being able to visit Roodeplaat would luckily be replaced by thankfulness.

        I reckon that as I got my gear ready the night prior to going I started leaning towards focusing on photography, in stead of combining it with a bird atlas list at the reserve. After all, together with my wife I had already made multiple bird atlas lists at the reserve, but never before gone solely for bird photography. I knew a good spot in the reserve for morning photography of nest-building weavers. Here, two less common species (for Pretoria) actively breed and nest during spring and summer, with nest-building starting in late winter.

        So I found myself at the reserve at roughly 07h00 and slowly started towards the weaver colony before the sun had started to peek over the Bronberg range. Nevertheless, with the Nikon D800’s great low-light performance I kept my eyes and fingers ready for any nice photo-ops. About a hundred metres from the colony there is a cluster of reeds right next to the trail where Southern Red Bishops are always active during early summer. Here I got one decent photo of a common Southern Masked-Weaver female in very early sunlight. Even though bird-photography on-foot is arguably not ideal, the birds in the reserve are relatively trusting of people walking by – especially where trails pass closely by natural bird hotspots. 
        When I reached the weaver nests I didn’t spent time looking for the best spot, but went with memory and settled in a spot close to newly weaved nests that were desirably located. I noticed the birds were slightly agitated by my presence, so I got out a very high-tech piece of camouflage - a brownish-yellow table cloth. Deciding to give the birds time to accept my presence, I waited and checked my settings, making initial adjustments to exposure after some test shots. The first species that I noticed and which gave me some nice displays was the Cape Weaver – which has a lot of attitude. After the first territorial displays at a nest, the other weavers started to ignore me and thinking (on some instinctual level) of preserving good chances of procreating. It turned out that two Cape Weavers had nests within good photo-range and –angle and these two were constantly in battle through song and display. After some time one or two Village Weavers also mounted the stage. These seemed to have started their nests later than the larger Cape Weavers and were not only bullied by the latter, but sometimes robbed of weaving material. During all the above I was often at a loss to decide between settings for flight and others more suited for perched birds. Both these extremes, and some in-between, produced nice photos, though I obviously missed many shots.

        At about 08h30, shortly before the light started to get slightly harsh, I was electrified with excitement as a Black-shouldered Kite (probably the resident kite that I had seen many times prior) flew in behind the weaver’s willow trees and landed a short stone’s throw away from me. It seemed to not have noticed me and was initially slightly hidden behind a willow. Wearing the table-cloth as a hood/cape slowly and trying to keep my posture more like that of a four-legged creature I slowly moved towards the raptor (luckily no-one was about to see all of this!). As I neared it was looking away from me and just before getting out from behind the last small tree that lay between us I made my final adjustments to settings – expecting it to take flight once it had seen me. It was probably only one or two seconds after having my focus points on it that it jumped into flight – my heart speeding elatedly as I clicked away. Its flight path had been quite desirable and I quickly looked at my play-back, and smiled.

        I stayed close to the spot where I had photographed the kite, focusing on other weaver nests. There were a few nice opportunities at the new nests and then the Kite came back – choosing roughly the same perch! I missed it coming in and the perched and second take-off photos all came out with too many undesirable elements (mainly twigs and branches being inconsiderate :P). Nevertheless, I might have found a favourite perch and will be aiming for the spot when I can go again.

        All-in-all, for all the bird-watching that I have done at Fearie Glen, the reserve surprised me with its photographic potential. If you look for the seasonal hotspots, are willing to put some effort into optimizing your chances at good photos and are mindful not to take your camera gear into remote sections of the reserve where mugging might be a potential occurrence, then this popular municipal reserve can be a great patch for bird photography.

General Info:
         For those of you who are not familiar with Fearie Glen Nature Reserve here is some basic info. As its name suggests this Pretoria municipal nature reserve lies in the suburb of Fearie Glen. It is spread along a section of the Moreleta River and includes portions of the Bronberg range of quartzitic hills. The reserve covers and area of 128 ha and has an extensive network of hiking trails. It can be regarded as reasonably safe. Criminal elements have from time-to-time been flushed out of the reserve by police, and at most times a good number of hikers are about. I would however not recommend that women hike through the remote portions of the reserve alone and neither would I recommend taking valuables into these sections if you are not part of a group. Nevertheless, over the past few years the reserve has probably been safer than most undeveloped places in Pretoria. Entrance to the reserve is dirt cheap (R5 per adult at the time of writing) and there is a large guarded parking area at the reserve entrance. At the entrance/office there are toilets and a drinks-and-snacks vending machine. Dogs on leashes are allowed inside the reserve (watch your step – Pretoria residents tend not to remove their dogs’ landmines from parks and trails), but apart from these the only facilities are the hiking trails, benches and a wooden platform along the river that is wrongly called a bird-hide. Gate times are from 6AM to 6PM. The amount of visitors that the reserve gets on a daily basis is a witness to its natural beauty that stands in the midst of our capital city’s eastern suburbs.

Wildlife:
        Fearie Glen Nature Reserve probably has most to offer bird watchers in terms of wildlife. It has a nice variety of typical resident species which is augmented through the seasons by nomadic and migratory species. Some of the common species in the reserve that I am quite found of are Red-throated Wryneck, Rock Martin, Chestnut-vented Tit-Babbler, Red-headed Finch, Cape Grassbird and African Black Duck. Look out for Giant Kingfisher and Black-shouldered Kite. In summer a host of weavers and allied species put on their summer displays, including White-winged and Red-collared widowbirds, Thick-billed Weaver and Southern Red Bishops. Smaller seedeaters abound – Yellow-fronted, Streaky-headed, and Black-throated canaries, Common Waxbill, Jameson’s Firefinch (uncommon) and Cut-throat Finch to name a few. When up on the hills keep your eyes open for Cinnamon-breasted Bunting (nomadic), Striped Pipit, Dark-capped Yellow-Warbler (summer), Amur Falcon (summer) and Fairy Flycatcher (winter). Other species that might be encountered in the reserve are Common Scimitarbill (uncommon), Spotted Eagle-Owl (not uncommon), Verreaux’s Eagle (uncommon), Brown-backed Honeybird and Lesser Honeyguide (common).  
       The reserve's once-abundant larger mammals, or rather small game, have at times suffered poaching, nevertheless interesting species persist under the radar. Rock hyrax are common on the highest hills, Vleirats occur in along the river, Bushpig have been encountered and Small spotted genet, Porcupine and Hedgehog are present, to name a few. I believe that Caracal are present in the reserve, as they are often seen on the nearby and quite developed CSIR kopje. Plans are currently in place to re-introduce some small game into the reserve. This will hopefully make the reserve’s ecosystem more balanced.
