🐾 Maybe the reason I love animals so much, is because the only time they have broken my heart is when theirs has stopped beating.

Under the charm of Chameleons

I haven't seen a Chameleon in my garden for about 10 years now. In fact, I can't remember when last I even saw one in the wild.Two decades ago I used to encounter them on virtually a daily basis and I can still remember the thrill every time I watched them change colour or catch a fly. Progress, loss of habitat, veld fires and the illegal trade in Chameleons all play a big factor in their plummeting numbers. I don't even have any photographs of one, except a very old one from about 15 years ago, taken in my garden, as he was scuttling for cover. So I've resorted to sketching and painting them.


There are about 200 species of chameleon with 19 recognised species in South Africa. They are found all over Africa and Madagascar, with a very few occurring in Europe or the Arabian Peninsula. There are no true chameleons in America except, interestingly, a species of chameleon that was imported into Hawaii and has now established a flourishing population there.


Having chameleons in the garden is very beneficial. They eat all the goggas and pests that gardeners don’t like and not only that, they are wonderful little animals, perfectly adapted to their lifestyle of camouflage and ambush. And there are some things we can do to help preserve this species, like refusing to buy them from street hawkers and creating a chameleon-friendly garden. I came upon this interesting article by Kay Montgomery published on IOL Lifestyle in 2014, and thought I would publish some of it here to help spread the word and save these wonderful little creatures.

The most important fact about chameleons is they need a fairly large area in which to roam. In Johannesburg, gardeners are being encouraged to link up chameleon-friendly gardens in a single neighbourhood. It is hoped that these gardens will merge to create corridors of chameleon habitat which will make it possible for populations of chameleon to flourish.

Here are some tips for developing a chameleon-friendly garden:
  • Reduce your lawn. To a chameleon, a large lawn is a giant desert. It contains no food, has no perches and no protective cover.
  • Thin out your trees. A garden filled with trees with low-hanging branches is a nightmare for chameleons. The branches of trees (pines and oaks in particular) are too thick for the chameleons to move along. They attract little insect life and offer no nectar.
  • Plant large thin-stemmed shrubs. Heaven for chameleons is a garden filled with a dense under-storey of shrubs with a range of perch sizes for juveniles and adults.
  • Provide food. Chameleons eat small insects such as moths, butterflies, flies, fruit flies, aphids, woodlice, beetles, spiders and small grasshoppers. 
  • Develop a compost heap in a quiet corner of the garden with the precise purpose of breeding insects. Baby chameleons will relish the tiny flies, grubs, beetles and gnats that thrive around a compost heap.
  • Build an insect hotel. Very fashionable in Europe, insect hotels are artistic columns or cubes of plant material that are glued or wired together. The common theme is that each material must be considered a suitable home by respectable insects and spiders. A hotel could include a mishmash of pinecones, hollow bamboo stems, lotus pods or even old pieces of wood with holes of different sizes drilled into the stem.
  • Plant flowering shrubs. Chameleons thrive in a garden that has a complete ecosystem of small, medium and large flowering shrubs which are constantly attracting insect activity. Smaller flowering shrubs covered in flowers are particularly loved by insects and are regarded as food table bridges between large twiggy shrubs. Many of the honeybee-friendly plants, such as euryops daisies, ribbon bushes, sage, fireball lilies, gazania and vygies will attract a variety of insects.
  • Plant large shrub trees: Adult chameleons thrive in the higher perches found in large shrubs or small trees such as the dune crowberry, pompon trees, sweet thorn acacias and wild olive.
  • Remove predators: Cats are one of the biggest threats to chameleons, birds and microfauna in the garden.
  • Avoid using pesticides that kill flies, crickets, ants and micro-insect life that chameleons rely on for their food.
  • Avoid illegal traders. If you see indigenous chameleons for sale, they are not legal. You are urged not to buy them.
What to plant

A chameleon-friendly garden is as much about the structure of the vegetation as it is about the plants. This notwithstanding, here is a list of chameleon-friendly plants:
  • Low-growing groundcovers: Try the lilac carpet geranium (Geranium multisectum), gazanias, bulbine, dwarf agapanthus or kingfisher daisy.
  • Shade-loving shrubs under trees: Try the spurflower (Plectranthus spp.), asparagus fern (Asparagus densiflorus), ribbon bush, arum and fireball lily.
  • Low-growing shrubs with thin branches: Confetti bush, euryops daisy, tea bush or azaleas.
  • Larger shrubs with thin branches: sage bush (Buddleja salviifolia), hop bush, mahonia, lion’s ear, polygala or dune crowberry (Searsia crenata).
Chamaeleo dilepis (Flap-neck chameleon) - The Flap-neck is the most common chameleon found in Gauteng (South Africa). The colouring here indicates that it is not feeling threatened but the change of spots is getting ready, just in case!

 Image credit - Here it is quite clear that he is very upset and not impressed at all!

It is very difficult to tell the different species apart. At first glance, they all look quite the same - all small, greenish-brown, with rolling eyes. But on closer inspection, it appears that there is a large amount of colour and scale variation, even within the same species. Luckily, with the help of genetic tests, it is now possible to make a better distinction between species, because each one has its own specific DNA code.
This makes further work on the morphological differences between species possible.

Any animal that can change colours and look in two directions at once is worth learning more about. Armed with a tongue you have to see to believe, the chameleon may be one of the coolest reptiles on the planet. I can only pray that in generations to come, chameleons can still be found roaming the trees of South Africa freely.

Together we can make a difference.

Winter - Fire and Ice


Mid-winter (July) in South Africa and the Aloes flower fiery-red against the white of frost. I've been dreading the frost, as some years it has killed all the flowers in the bud. I do have one aloe (the largest of the three, pictured below, which started flowering last) which doesn't seem to be doing so well, the flowers don't seem to have much colour, but hopefully the flowers will still reach maturity, as long as we don't have any more stints of heavy frost.


My chooks have left large, bare patches all over the garden, scrounging for any available greenery as the lawn is all but non-existent.


Lots of mist this morning, a sign that, albeit cold, the day is going to be bright and sunny!


Early morning caught all the birds patiently waiting in the bare peach tree for the first rays of the sun and the feeding tables to be filled, a daily winter’s morning occurrence. This morning there weren’t as many, some mornings I’ve counted up to 50 before losing track. They mostly consist of Weavers, Laughing Doves, Bishops and Sparrows with the odd Bulbul.

Some say the world will end in fire;
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
~ One of Robert Frost’s most popular poems, published in December 1920 in Harper’s Magazine

Winter, Bonsai and other ramblings


It took a while for summer to admit to defeat, pummelling us with heat wave after heat wave even well into autumn and autumn was decidedly short-lived, dumping us straight into icy weather with lots of snow all over the country, Here in Tarlton (Gauteng, South Africa), we suffered low temps of only 11C during the day, with the nights and early mornings well below freezing point. And to make matters worse, we even had some rain. Rain in winter is not in the scheme of things here in Gauteng, we're a summer rainfall area. I was worried about my succulents, but I needn't have been, they didn't seem to mind the rain, it's frost that's deadly to them. And luckily we've not seen much of that yet. We just have to get through July and then the worst is over. Even my Chooks aren't particularly impressed with the cold - Kiep comes in every day for a stint in from of my gas heater, laying down, spreading her legs and wings, soaking up the heat and looking a lot like road kill!


And much to Jacko's chagrin, she commandeered his blanket in front of the heater, spending most of the morning until it was time to go outside for a snack.


Don't get me wrong, I much prefer the cold to the heat-waves we've been having, and I am extremely grateful to have a warm roof over my head, something many people don't have. Situated barely 100 miles (160km) south of the Tropic of Capricorn, you might expect Johannesburg, South Africa's commercial capital, to be bathed in tropical heat all the year round. But this city of 4m inhabitants lies 5,500 feet (1,700 metres) above sea level and it is now mid-winter. So although the middle of the day is generally warm, with clear blue skies and a sun too hot to sit out in comfortably, the nights can be bitterly cold, with temperatures dropping below freezing. But apart from the fancier hotels and some upmarket office blocks and homes, almost no one has central heating—or adequate heating of any form for that matter. South Africa’s several million strong homeless population was particularly hard hit as temperatures plunged to record lows in many parts of the country and in May 2007, at least 17 people died from exposure, highlighting the country’s chronic housing shortage.


But winter is also the time when all my Aloes start flowering and when nature provides extra sustenance to her wildlife through nectar in these beautiful flowers. Every winter my garden is flooded with Sunbirds and nectar-loving insects, bringing great joy to my heart. Winter is also when nature gets rid of the old and weak, preparing the landscape for new life in spring.


Last spring I did the unthinkable - I planted my 1983 Natal Fig bonsai in the garden. I got him as a 3-year old in 1982 and for 33 years I've been tending him, neglecting him, tending him again, pruning him wrong, taking him to an expert to be fixed, pruning him wrong again, putting him outside every spring and carrying him into the house every late-Autumn for the winter. A symptom of the neglect is that he got very big. He has been in the same pot for years without me taking him out and trimming his roots to maintain a reasonable size. Getting heavier and heavier, it became a major job for two men to move him inside every winter and spring. His trunk is beautiful, thick and gnarled, with aerial roots hanging down the one side, anchoring him more firmly to the ground.


But as time went by, he started showing real signs of neglect. When I looked at this photo of him (above) which I took last July 2015 (winter) inside my flower room, it was clear to me that he was at the end of his tether and beyond saving. My heart broke. But now I've got this short-coming that I can't kill anything, not even an un-saveable plant, so in September last year (Spring), I chose a protected spot in the garden and plonked him in a well-prepared hole and said to myself, "que se ra, se ra". Deep in my heart I'm suffering because I've got this suspicion that this winter might kill him, being an Eastern Coastal Belt Forest resident of South Africa.

After a month in the garden, there was already a vast improvement, as can be seen in the pic of him in the garden. Most of the branches had already filled up with new leaves and he was looking bright green and much healthier. In the meantime I've read up a bit more about about this tree and it turns out that the versatile Ficus natalensis (also known as "Mutuba" to locals) is wind and drought resistant and tolerates temperatures from -5C – 30+C. It occurs naturally in both moist woodland and dry open areas of the country and is evergreen, which did not seem evident when I had him in the pot, as he lost a lot of his leaves every winter. With a height of 5m-20m and a spread of 4m-8m, I might just have to change my garden when he gets bigger, if he survives our severe Tarlton frost.

My "gardening skills " ego has been dealt a great blow with the "loss" of my Bonsai, as Ficus natalensis is one of the most widely used species by Bonsai enthusiasts. The fat stem and intricately gnarled roots are perfect for achieving a variety of popular Bonsai styles. This species grows ’banyan’ roots naturally which can be showcased as dramatic air-root or root over rock styles. The Natal Fig grows fast and is quite forgiving if incorrect watering methods are applied, making this the ideal choice for the novice enthusiast. So how "novice" am I ........?

Lichens and mosses

A leafy foliose lichen (Xanthoparmelia substrigosa) on the trunk of my Acacia karroo tree

After heavy rains we had in early April, many of my trees, and rocks, sported lichens and mosses, totally fascinating! And now, two months later, they are still there, but have turned pale grey. But understanding lichens is complex (to me at least!), so I've had to resort to an internet search to explain them.

Worldwide, over 20,000 species are known. A lichen is not a single organism. Rather, it is a symbiosis between different organisms - a fungus and an alga or cyanobacterium. Cyanobacteria are sometimes still referred to as 'blue-green algae', though they are quite distinct from the algae. The non-fungal partner contains chlorophyll and is called the photobiont. The fungal partner may be referred to as the mycobiont. While most lichen partnerships consist of one mycobiont and one photobiont, that's not universal for there are lichens with more than one photobiont partner. When looked at microscopically, the fungal partner is seen to be composed of filamentous cells and each such filament is called a hypha. These hyphae grow by extension and may branch but keep a constant diameter. Amongst the photobionts there are those that are also filamentous in structure while others are composed of chains or clusters of more-or-less globose cells.


Given that they contain chlorophyll, algae and cyanobacteria can manufacture carbohydrates with the help of light via the process of photosynthesis. By contrast, fungi do not make their own carbohydrates. Every fungus needs existing organic matter from which to obtain carbon. In a lichen some of the carbohydrate produced by the photobiont is of course used by the photobiont but some is 'harvested' by the mycobiont.



Lichens are classified with the fungi (being sometimes referred to as lichenized fungi) and can be found growing in almost all parts of the terrestrial world, from the ice-free polar areas to the tropics, from tropical rainforests to those desert areas free of mobile sand dunes.

Foliose lichens could be thought of as halfway between crustose (two dimensional) and fruticose (erect). Though obviously three dimensional, they grow in a more-or-less sheet-like form, but often with a lobed appearance. They are not attached by their entire lower surfaces to their substrates. Indeed, some foliose lichens are just centrally attached.


Another part of the same tree trunk, lower down, was covered in moss. Now Wikipedia says, "Mosses are small flowerless plants that typically grow in dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple, one-cell thick leaves, attached to a stem that may be branched or un-branched and has only a limited role in conducting water and nutrients."



The same thick mat of moss also formed on a rock on my patio, but both of them never quite got to the thick stage and have now all but disappeared. The moss life-cycle starts with a haploid spore that germinates to produce a protonema (pl. protonemata), which is either a mass of thread-like filaments or thalloid (flat and thallus-like). Massed moss protonemata typically look like a thin green felt, and may grow on damp soil, tree bark, rocks, concrete, or almost any other reasonably stable surface. This is a transitory stage in the life of a moss, but from the protonema grows the gametophore ("gamete-bearer") that is structurally differentiated into stems and leaves. A single mat of protonemata may develop several gametophore shoots, resulting in a clump of moss. But they do need a lot of damp to continue surviving.

Most mosses rely on the wind to disperse the spores, but It has recently been found that microarthropods, such as springtails and mites, can effect moss fertilization.


It seems that, given enough moisture, moss might still take over the world! lol!

Black-headed Heron (Ardea melanocephala)


I had an awesome visitor this morning, a Black-headed Heron (Ardea melanocephala). We don't often see them, mostly just after a veld fire, when they will snack on some unfortunate crispy tit-bits left in the wake of the fire. But this morning he was close to my garden fence and, as previously, didn't seem that perturbed about me taking some photos.

They mostly hunt near water, but will also hunt well away from water, taking large insects, small mammals, and birds. It will wait motionless for its prey, or slowly stalk its victim. It's fascinating to watch, but his patience long outlives mine, as he can stand motionless for longer than 10 minutes and by that time I think he's fallen asleep! Both sexes are alike, so I have no idea whether this is a male or a female.


Monogamous and usually colonial, they breed in small, mixed-species heronries. The male calls from a perch to attract a mate, raising its head and giving a loud yelp, sometimes extending its bill vertically as it does so. I've only heard that sound once, and I was totally thrilled!

African Striped Skink (Trachylepsis striata)


This Striped Skink was enjoying the sun on the wall of my bathroom court-yard garden and she was heavily pregnant (pic taken last October). Mating occurs between October and November, with a gestation period are 90 to 100 days, so I presume she was to give birth within a month or two, usually a single litter of 3 – 9 babies. Growth is relatively fast, sexual maturity is reached in 15 – 18 months. Last summer, my Skinks had several litters in my bathroom court-yard garden, much to my delight.

The African Striped Skink (Trachylepsis striata), commonly called the Striped Skink, is a lizard in the skink family (Scincidae). The species is widespread in Southern Africa, including extreme southern Angola and Zambia, Namibia, Botswana, Zimbabwe, Mozambique, and parts of central and eastern South Africa.


Skinks typically seek out sheltered environments out of the elements, such as thick foliage, underneath man-made structures, and ground-level buildings such as garages and first-floor apartments. When two or more skinks are seen in a small area, it is typical to find a nest nearby. Skinks are considered to be territorial and often are seen standing in front of or "guarding" their nest area.

Two males squaring it off, ready to defend their territory

This skink is brown or bronze coloured with two yellowish stripes that run lengthwise on either side of the spine. Both sexes grow to a length of 25 cm.1 Their tails are often missing due to predators.

To bless this kind earth... and yourself


Now that we're over the worst of summer (and it really was the pits, with extreme heat-waves, temps in the 40℃'s and drought) and had some lovely rain to break the heat and drought, I'm enjoying time outside in my garden again. I just get absolutely cranky, and listless, when it gets that hot, and can't seem to get around to doing anything outside. But as we all know, we NEED to get outside, we need to spend time in nature, otherwise life becomes unbearable. Well, for me anyway. My plants and the birds in my garden are part of my family, and I feel as though I've lost track of what's going on in their lives. I just did the bare necessities during that heat, filling the water bowls and feed tables and the rest, like watering the garden, was left up to my trusty garden manger, Chrissie. I even thought of telling her to chat to the birds, because I wasn't getting round to it!


But my garden doesn't seem to have minded my absence. It's like a jungle out there after all the rain. Nature's revenge to neglect is that, when left undisturbed and given time, she will reclaim anything built by humanity. So basically, no need to feel guilty here, life finds a way.


 There's a pathway somewhere in there, totally covered now by Bulbine and Sword ferns.


Even the birds don't seem to have noticed my absence. No excitement or fluttering or welcoming twittering when I started spending time in the garden again. Maybe they were even pleased about not being constantly stalked by my camera. Eating and bathing and nesting carried on as usual, making me feel a bit unwanted...

Hedgehog lore and legends - Snakes alive!

Are hedgehogs in danger from snakes?


It's not surprising that such a strange-looking little animal as a hedgehog should be the subject of some extraordinary legends and beliefs. Strange hedgehog activities such as running in circles and 'self-anointing' (smearing their spines with their own frothy saliva), are definitely fact, not fiction, through we don't know why they do these things.

But there are also a number of intriguing legends about hedgehogs, most of them dating back to the distant past.

The myth, particularly prevalent in South Africa, that snakes have been found with hedgehogs in their stomaches, is a long stretch of the imagination. It would be quite impossible for a snake, no matter how big, to swallow a rolled-up hedgehog.

A hedgehog under attack from a snake would immediate roll up and protect itself with its bristling spines. If the snake persists, it is likely to damage itself severely on the spines, and the hedgehog may seize the opportunity to sink its teeth into the snake and roll up again. In the end, the hedgehog often makes a meal of its former enemy!

Have we evolved for the better?


The animal kingdom is filled with almost an infinite variety of creatures. Scientists discover new species and sub species every year. Each one is a wonder onto itself and one could labour for years to uncover its secrets. It is an unfortunate fact that the closest that most of us get to wildlife is through bars at the zoo. Our urban lifestyle has the effect of cutting us off from the glorious world of the animal kingdom.

Every animal has a lesson to teach us that we are not hearing. We may think that we have evolved, the question is, at what cost?

A Butterfly Life
As the caterpillar sleeps inside its cocoon

Like a baby wrapped in her blanket 

She waits and waits until she blooms 
Into a beautiful new life 

With wings of deep sapphire blue

She takes her first flight, soaring high
Into the clear cornflower sky

She flutters over to perch on the pink flowers 

To sip the sweet nectar of pure gold 

But this butterfly is daintier than a ballerina

Like a leaf in the wind, but controlled

So delicate and fragile

But so free, so free this butterfly will always be.

BULLFROG at my pond - 1am 10 Nov 2015

Image from Milan Zygmunt 500px

The most wonderful sound to wake up to - the call of a Bullfrog (Pyxicephalus adspersus) at my pond! I haven’t heard one for years, so I immediately jumped out of bed (at 1am!), grabbed the torch and rushed to the pond. It took me quite a while to find him - first of all he heard me, so kept quiet for a while, but then continued - and secondly the torch light was rather dim. But eventually I found him. There he was! Cleverly hidden under a large rock in the shallows. I did have my camera with me, but the pics showed nothing in the darkness. So I looked for him the next morning and did find him (I in fact found two), but he was not nearby the size of the pics below - a youngster, about 10cm (4”) long and the minute he saw me, he left the safety of the rock he was hiding under and swam to deeper waters. So once again, no pic. It’s hard to believe that such a small chap can have such a booming voice!

The large rock (top right) under which he was hiding

Their loud booming calls (to attract a female) can be heard for miles and the first time you hear it (for me it was in the early 80’s at my previous wildlife pond), you’re not sure whether to investigate or to flee!

This species occurs widely in South Africa, Swaziland, Namibia, Botswana, and Zimbabwe, extending north to southern Angola, Zambia, Malawi, Mozambique, Tanzania, and Kenya. One of the most adaptable amphibians on earth, Pyxicephalus can tolerate some of the harshest environments in Africa. Certain areas of their range can be completely dry for years at a time, and can reach surface temperatures over 100 degrees F, and drop to below freezing during the winter. Protected in an underground estivation chamber, the frogs wait it out until more suitable conditions occur. When the rainy season begins (usually November), they come out of their chamber, occupy temporary floodplains and rapidly drying puddles scattered around the African countryside, just for a few short days or a couple of weeks.

I am totally thrilled that they have taken up residence in my garden!

It is the largest amphibian found in southern Africa. Males can reach a snout-vent length of 24,5 cm and a mass of 1.4 kg

It is common in many of the southern parts of its range, it has apparently declined in South Africa, especially in Gauteng Province, but it is still locally common in some places. Boycott (2001) declared the species to be extinct in Swaziland. It seems to be very uncommon in the northern parts of its range, with very few confirmed records from Zambia, Malawi, Tanzania and Kenya (though this might in part be due to identification problems)..
.


Photo African bullfrog SA Reptiles
.
It is a species of drier savannahs. It is fossorial for most of the year, remaining buried in cocoons. They emerge at the start of the rains, and breed in shallow, temporary waters in pools, pans and ditches. They are active by day during the breeding season. They can tolerate habitat alteration, but not urbanization.

Male Pyxicephalus adspersus can reach lengths of more than 9 inches and weigh over 2 pounds. Females are much smaller. Males are olive in colour, with yellow to orange on the throat region. Females are olive to light brown with cream to white throat areas. Both sexes have ridges running laterally on the dorsal surface. Juveniles are much more colourful than adults. Several white to yellow lines run down the animal's dorsal area on an overall mottled background. Both these dorsal lines, and mottling disappear with age. Adults have a spade like metatarsal tubercle on each hind foot to aid in digging. The front toes are thick and blunt with no webbing, the rear toes are slightly webbed. These frogs have massive skeletons with extremely large, heavy skulls. The bottom jaw has three odontodes which act as huge teeth, and are used in restraining struggling prey.

During the breeding season, males will congregate in large groups. Much aggression occurs in these groups with larger males pushing, pursuing, biting, even consuming smaller males. The large males will push their way to the centre of the group, establish and defend a small area and begin calling. The call lasts about a second and can be described as a deep low-pitched whoop. The females will hear this call and swim underwater to the centre of the group, to avoid the smaller males and surface in the defended area of a larger male. As they surface, they are persuaded until finally being seized by a male. Amplexus occurs in shallow water to allow the pair to stand on the bottom. Eggs are fertilized above the water's surface. As many as 4000 eggs may be released. The males exhibit parental care. Males will watch over and defend the eggs which hatch in two days. After hatching, the tadpoles will feed on each other, as well as on small fish and invertebrates. Defending males will continue to watch over the tadpoles which will metamorphose within three weeks.

Behavior
These frogs have a short active period depending on the rainy season. The majority of their lives are spent estivating underground. Adults will burrow underground using the metatarsal tubercle on their powerful hind legs. Juveniles lack this tubercle and must resort to utilising an existing burrow made by some other animal. They slough off several layers of their skin's epidermal cells which form a tough cocoon. Most of their bodily functions slow or shut down all together. This period of dormancy may last a year or more. During the rainy season frogs will sit partially buried with the nose exposed, taking advantage of any smaller animal unfortunate enough to pass by

Food Habits
Pyxicephalus adspersus is carnivorous and will consume nearly any animal that can be overpowered and can fit in their huge mouths. Cannibalism is a common occurrence beginning the moment they metamorphose. Many of their first meals will be a member of the same egg mass. Other prey items may include invertebrates, other species of frogs, reptiles, small mammals, and even small birds. The tongue is folded over inside the mouth. To capture a potential meal, it will drop its lower jaw with considerable force, causing the tongue to flip over and out of the animal's mouth, seizing the prey

Did you know?
Certain areas of their range can be completely dry for years at a time, and can reach surface temperatures over 38 degrees C, and drop to below freezing during the winter. Protected in an underground estivation chamber, the frogs wait it out until more suitable conditions occur. In fact, the majority of their lives are spent estivating underground. They slough off several layers of their skin's epidermal cells which form a tough cocoon, which prevents the evaporation of body fluids. Most of their bodily functions slow or shut down all together. They absorb water stored in their bladder. This period of dormancy may last a year or more. When the rainy season begins, they occupy temporary floodplains and rapidly drying puddles scattered around the African countryside.Males have two breeding strategies, depending on their age: Younger males congregate in a small area, perhaps only 1 or 2 square meters of shallow water. The larger males occupy the centre of these breeding arenas or leks and attempt to chase off other males. In fact they fight, causing injury and even killing one another. The dominant male attempt to prevent other males from participating in breeding. A female approaches the group of males by swimming along at the surface until she is within a few meters of the group. Then the female dives to avoid the smaller males and surfaces in the defended area of a larger male in the middle of the group. She is soon grasped by one of the larger males, and mating ensures. Most of the females are mated by the dominant male in his territory.

The major threat through most of its range is harvesting of frogs for local consumption, which is believed to be responsible for some population declines. In South Africa, breeding habitat has been lost due to urbanisation. This species is sometimes found in the international pet trade but at levels that do not currently constitute a major threat.

Economic Importance for Humans: Positive
African bullfrogs are eaten by humans, and have been collected for the commercial pet trade.

Economic Importance for Humans: Negative
Because these frogs are such resilient animals, they might potentially have negative effects on the surrounding ecosystem if introduced by humans beyond their natural range.

Listed as Least Concern because, although it is losing breeding habitat in places due to urbanisation, and it is also eaten in parts of its range, it has a wide distribution, is tolerant of a broad range of habitats and has a presumed large population.
(Much of this info from Animal Diversity Web)

Giant Bullfrog (Pyxicephalus adspersus). This fascinating frog species can be viewed by the general public at The National Zoological Gardens of South Africa (NZG). NZG has decided that, in addition to having several amphibian species on display, it will also want to play a role in the conservation of frog species in situ (in the wild). A starting point for the NZG will be to install an on-line weather station on the site in order to correlate amphibian behaviour with environmental conditions.

Hedgehog Lore and Legends - Morning milk

Do hedgehogs suck cows' udders?


It's not surprising that such a strange-looking little animal as a hedgehog should be the subject of some extraordinary legends and beliefs. Strange hedgehog activities such as running in circles and 'self-anointing' (smearing their spines with their own frothy saliva), are definitely fact, not fiction, through we don't know why they do these things.

But there are also a number of intriguing legends about hedgehogs, most of them dating back to the distant past.

It is possible that hedgehogs occasionally attempt to suck milk direct from recumbent cows. And there's another way they obtain milk in the wild - early on a summer morning, cows sit quietly chewing the cud and waiting to be taken for milking. Their full udders often ooze drops of warm, sweet-smelling milk onto the grass, attracting any passing hedgehogs.

But nobody really knows!

Hedgehog lore and legends - Fruit picking

Why should Hedgehogs collect apples?


It's not surprising that such a strange-looking little animal as a hedgehog should be the subject of some extraordinary legends and beliefs. Strange hedgehog activities such as running in circles and 'self-anointing' - smearing their spines with their own frothy saliva - are definitely a fact, not fiction, though we don't know why they do these things. But there are also a number of intriguing legends about hedgehogs, most of them dating back to the distant past.

Some people claim to have seen apples punctured as though by spines around a hedgehog nest. Others tell of a hedgehog picking up apples in its mouth, assembling them in a group, then turning over on its back and rocking to and fro on top of them. Others say they have seen a hedgehog waling away from a tree, carrying apples impaled on its spines.

But even if hedgehogs are physically able to carry apples, there's no point in doing so. They eat hardly any fruit and can easily take what they find lying on the ground. Nor do they hoard food for the winter; they store their energy supplies in the form of fat.

So don't believe everything you hear! A dose of good common sense goes a long way in protecting these beautiful little creatures from any misunderstandings.

Mother Nature's blessings and her fury

After months of drought, the Sabie River in full flood in the Kruger National Park, South Africa

After some weeks of suffering a terrible heat wave leading to loss of life, coupled with serious drought in parts of our country (South Africa), Mother Nature blessed us with lots of rain but also some of her worst-ever fury, dumping days of rain and hail bigger than golf balls, causing extensive flooding and damage to properties in Krugersdorp in the second week of January.

KeyWest Shopping Mall roof collapses under the weight of the hail

The roof of our local shopping mall in Krugersdorp, KeyWest, collapsed from the weight of the hail, causing makor damage to most of the shops in the mall, with flooding and ceilings falling in, resulting in the closure of the mall until repairs could be done.

It's been raining almost every day ever since and this morning I woke up to dark skies and with the rising sun beautifully highlighting the foliage on the trees with a light drizzle to boot. My garden is smiling in leaps and bounds!

Yesterday's rain


Solly's chooks were by no means intimidated by the black skies or the rain and kept on having their early 6am breakfast (this drive-way is in dire need of renovation! It's on my list ...!)

Extreme weather is occurring all over the globe at the moment, and it's easy to consider an apocalypse could be on the horizon. While we hope this is far from true, it's impossible to ignore the droughts, fires, storms and heat waves we've experienced lately, with Pretoria (Gauteng, South Africa), experiencing temperatures in the 40℃'s, the hottest it's ever been since 1865. And here at home, our temps hit 39℃, something I've never experienced in my 40 years of living in Tarlton.
