Black Velvet Spider

If you want to live and thrive, let the spider run alive.
~American Quaker Saying

This black Velvet Spider has lived in the bark of an old log in my garden for approximately 2 years now and she lets me coax her out for a photographic session every now and then. These spiders are robust and deliberate in the way that they walk and she even allows me to gently stroke her abdomen and thorax, which is covered in thick, smooth, velvety hairs.

The velvet spiders (family Eresidae) are a small group (about 100 species in 10 genera) of almost totally Old World spiders (exception: a few species are known from Brazil).

Velvet spiders are found under rocks or bark resting in a sheet of dense white silk and are often confused with baboon spiders. They can live up to 5 years. Free living but rarely leave the safety of their webs.

Description:

12mm to 15mm in length. These robust spiders colouration may be from black, grey or a rich red. Body covered with hairs which give them a velvety appearance, hence their name. The abdomen is often lighter in colour than the rest of the spider. Abdomen may have 4 dimples on the top. The eyes are close together and the mouthparts are very robust looking for a spider that size. Legs are short and strong and they are widespread throughout Southern Africa.

Web:

These spiders build their webs under rocks, under loose bark. Their retreats consist of flat candy floss like dry sheets of silk. The silk is tough and has interwoven prey remains. Their nest-like webs are attached to the ground using silken anchor lines. Silken lines radiate from the entrance to their shelters. These lines are used to detect prey.

Venom:

Even though these spiders can be large in size they very rarely bite. Not much is known about the affects of their venom. It is highly unlikely that this spider’s venom is of importance to humans.

Notes:

Females seldom leave their webs in order to hunt. Instead, they prefer to wait for prey to wander into their webs and radiating silken lines. They prey upon tough skinned insects and other large prey items.

Southern Red Bishop

The Southern Red Bishop Male

The Southern Red Bishop ( Euplectes orix ) is common within Southern Africa, found in marshy grasslands and wetlands, with a height of around 13 cm’s and weighing in at around 23 Grams. The Bird feeds on Seeds and insects. These birds normally build their nest over a water body and are slightly different to the Black-Winged Bishop on their Face.

Every spring they return to my garden, the male's buzzing song alerting the female to the nest he's building for her. It also has various twittering calls and a nasal contact call.

It is 10-11 centimetres long and has a thick conical bill. Breeding males are brightly-coloured with red (occasionally orange) and black plumage. The forehead, face and throat are black and the rest of the head is red. The upperparts are red apart from the brown wings and tail. The upper breast and under tail-coverts are red while the lower breast and belly are black. The non-breeding male and female have streaky brown plumage, paler below. Females are smaller than the males.

Oryx

The GEMSBOK or gemsbuck (Oryx gazella) is a large African antelope, of the Oryx genus. The name is derived from the Dutch name of the male chamois, Gemsbok. Although there are some superficial similarities in appearance (especially in the colour of the face area), the chamois and the Oryx are not closely related.

Gemsbok are light brownish-grey to tan in colour, with lighter patches to the bottom rear of the rump. Their tails are long and black in colour. A dark brown stripe extends from the chin down the bottom edge of the neck through the join of the shoulder and leg along the lower flank of each side to the brown section of the rear leg. They have muscular necks and shoulders and their legs have white 'socks' with a black patch on the front of both the front legs and both genders have long straight horns.



Gemsbok generally live in herds of up to 40 individuals, often in association with other species of antelope or with zebras. The males are often solitary animals, however. Active from dawn through nightfall, it feeds on grass and leaves, and can survive long periods without drinking any water. The horns are effective weapons. When fighting, the head is lowered between the forelegs in order to impale the enemy.

Introduction to North America

In 1969 the New Mexico State Department of Game and Fish decided to introduce Gemsbok to the Tularosa Basin in the United States. The introduction was a compromise between those who wanted to preserve nature and those who wanted to use it for profit and promotion. 93 were released from 1969 to 1977. The current population is estimated to be 3,000. The reason the Gemsbok thrived is because their natural predators, including the Lion, are not present.


They are also to be found in the Kalahari Gemsbok National Park, which is located between the borders of Namibia and Botswana. The park covers an area of a little less than 10,000 square kilometers. The Kalahari Gemsbok National Park and the adjacent Gemsbok National Park of Botswana together occupy as much as 36,000 square kilometers. Since there is no barrier separating the two parks, the animals move freely from park to park.

Safe & Sound

THE HEDGEHOG'S NEST



Unlike most mammals, hedgehogs lack the insulation of a warm fur coat. And keeping the body warm requires a lot of energy, so as it goes into winter and it gets ready for hibernation, the hedgehog's temperature drops from the normal 35ºC to that of its surroundings: 10ºC or less.

The hedgehog's winter nest, known as a 'hibernaculum', is made of grass and especially of leaves, which are weatherproof and long-lasting. The hedgehog brings leaves to the nesting site in its mouth, a few at a time. It makes a pile, adding new leaves to the centre; they are held in place by the surrounding support of twigs, brambles, brushwood, etc. It then burrows inside and turns round and round, packing the leaves flat and ending up with a warm chamber with walls up to 10cm thick.

Next winter, the hedgehog will make a new nest, even if the old one is still usable.
