Red-Throated Wryneck

The Red-throated Wryneck has a height of 20 cms and weighs around 55 gms. The head is coloured brown while the bill is coloured grey. The Jynx ruficollis has a brown coloured throat, olive legs and a brown coloured back. The eyes are brown.

This bird forages for food on the ground.  The Red-throated Wryneck is usually seen hunting for food within the tree foliage (as seen in the photo captured below while walking about in the Sibuya Game Reserve).  This bird eats insects such as butterflies, bees, wasps, locusts and ants. These invertebrates are usually hawked aerially, killed and then eaten.

Red-throated Wryneck Jynx ruficollis is an ant-eating specialist with adaptations to assist in the mopping up of large numbers of Hymenoptera (Ant) prey.  Capable of holding hundreds of ants or ant larvae in each beakful, it is impossible for these birds to control all subsequent movement of prey, resulting in ants crawling around the birds beak and head when delivering food to the chicks.

Darwin’s Bark Spider

Darwin’s bark spider (Caerostris darwini) is an orb-weaver spider – a member of the family Araneidae. Regularly seen in the Sibuya Game Reserve‘s bush. Like other spiders of the genus, they display extreme sexual dimorphism, with large females and small males. Females vary in total body length from about 18 to 22 mm (0.7 to 0.9 in), males being around one third or less of this length, at about 6 mm (0.2 in).

The spider’s silk is the toughest biological material ever studied, over ten times tougher than a similarly-sized piece of Kevlar. The average toughness of the fibres is 350 MJ/m3, and some are up to 520 MJ/m3, making the silk twice as tough as any other spider silk known.

The web of Darwin’s bark spider is remarkable in that it is not only the longest spanning web ever observed, but is among the largest orb webs ever seen, at an area of up to 2.8 square metres (30 sq ft).  Nephila komaci, discovered in 2009, and some other Nephila species also make webs that can exceed 1 m (3 ft 3 in) across.

The spider was described along with a previously undescribed species of fly, which appeared to have a kleptoparasitic relationship with it. The flies often feed on the spider’s catches before the spider wraps them. Occasionally, spiders have been observed to chase away the flies when they land on something that the spider is eating.

Update on Sibuya’s Orphan Babies

After the trauma of the last few days we have to look to the future and now start to dwell on the positives.  Binki, Sibuya’s 11 and a half month old calf has been put in a boma with another orphaned older calf. Almost immediately they joined up and started grazing together which led the vet and carers to decide that she should just be left to graze. Although milk was put in a trough for her just in case, she ignored it and so far seems to be doing well without it.

The baby started off well and took to the bottle immediately on arrival at the sanctuary which was a huge relief. However as the sedatives wore off she became very traumatised and stopped drinking. The vet and carers decided to give her more sedative and very fortunately she started drinking from the bottle again.
Fortunately now she is no longer sedated and is accepting her bottle from her surrogate “mum” naturally and without drugs.
This is great news and although not out of the woods we are all cautiously optimistic.

Sibuya Game Reserve in Mourning

Sadly the heartbreak continues for Sibuya Game Reserve as Bingo died at 6.30 pm yesterday.
The day after he was downed (Thursday), the Vet noticed a white discolouration in his right eye – something seen before in similar cases and it is thought caused by the blood pressure building up from being down for so long. Unfortunately what we didn’t know was that by Friday night he had gone blind in both eyes and during the night he stumbled down the hill and into the Estuary. When we found him he was in the water in deep mud with a sheer cliff behind him. It was obvious that he had been struggling to try and get up the steep bank but kept slipping back into the mud. We spent the entire day putting rocks and branches around him to give him a foothold in the mud and cutting away at the bank so he could hopefully walk out. Sadly, although he managed to get out of the river a couple of times, he could not see the pathway despite our coaxing, calling and even prodding. By 6 o clock, with the day fading and the tide coming in, it was achingly clear that he had run out of strength, unable to help himself any longer and was about to drown in the rising water. The terrible devastating decision was taken to put him to sleep and save him further agony, fear and suffering.

Bingo
During the day I had a call from reception to say that a man was there sobbing and asking what he could to do help and at least could he please make a donation. The Receptionist said it was so tough for them as they hadn’t seen a grown man cry before… well as Bingo drifted off, there wasn’t a dry eye from the Vet to the toughest APU member at the scene. After days of almost breaking down emotionally, the final loss of our beloved Bingo was just too much to bear.

RIP Bingo – all who have met you have been blessed by the experience. I am so sorry that there was so much pain and suffering in the end, but please know we were always only trying to do what we thought was best for you.

Your loving Sibuya family who have found joy in your majesty.
