Catching the warmth of the early morning sun after a chilly night by perching on the top branches of the Erythrina caffra were an African Green Pigeon:
And a Cattle Egret:
We have got to know various members of the Urban Herd quite well over the years and have even named the more familiar among them. Before I return to them let me introduce you to an interesting South African breed of cattle called Bonsmara. Here are a few on a cattle farm in the Lothians area.
These reddish-looking cattle are the result of an extensive scientific breeding programme conducted by Professor Jan Bonsma from the Department of Agriculture to produce cattle that are well adapted to a sub-tropical climate; that will calve every year; and will produce good quality beef. The name is a combination of the name of the professor and ‘Mara’, the experimental farm on which they were bred. They animals have the attributes of both Bos indicus and Bos Taurus. Why this should make any difference I don’t know, but in order to conform to breed standards these cattle have to be de-horned!
Back to the Urban Herd. Look at the lovely shape of the horns on a cow we call The Master Hooter.
There are some interesting aspects about her, one of which you may have noticed is that, apart from an identifying notch in her ear, there is also a hole. Perhaps too many other cows have simple notches, although the pattern on the hide of this one is distinctive.
The other is that at some stage she lost the tuft at the end of her tail. The Urban Herd wander all over town and beyond, so who knows – it may have been grabbed by a dog or caught in a fence …
At this stage she and her companions are grazing along the road of our ‘industrial area’ on the edge of town. Behind her is a calf, sired no doubt by the Arctic Bull – who has sowed his wild oats across many of the Urban Herd cows!
Wait! Did you spot something interesting on the back of that calf? It looks equally interested and I felt ecstatic:
Red-billed Oxpeckers! How very exciting it is to spot these so close to home!
Cattle Egrets are the more usual companions of the Urban Herd, wherever they happen to wander.
Lastly, here is The Master Hooter’s Sister:
Cattle Egrets (Bubulcus ibis) are a common sight here, especially since the occasional appearance of the Urban Herd became permanent. Interestingly, Bubulcus is the Latin word for ‘herdsman’ – they certainly do appear to keep a close eye on their ‘charges’ and their relationship with cattle, buffalo, and even zebra are interesting to observe. Each animal appears to have an egret in attendance, ready to pounce on insects flushed by these large animals as they move through the grass. I have occasionally seen an egret pecking at ticks on the tip of a cow’s tail. They are also known to feed on frogs, small mammals, worms and eggs.
These are elegant looking birds, both on the ground and especially when they catch the late afternoon sun when in flight home to their communal roosting spots. I see them flying over our garden singly, in twos or threes, and sometimes many of them together. The tree in which many of them used to roost in town was cut down in an effort to get rid of them, so I am not sure where they go, although they have been recorded as flying up to 20km to their feeding areas.
These ones appear to be resting from their labours. If you look very closely, you may count more than the alliterative eleven basking in the late afternoon sun.
Does one say ‘Happy Earth Day?’ Can it be a happy Earth Day when the planet is mantled by an unseen enemy that has brought the world’s population to its knees, caused hunger, uncertainty, fear, suspicion and concern to the fore on a scale that no climate change warnings, earthquakes, tsunamis or volcanoes have managed to do? The spread of the COVID-19 virus has isolated us, caused us to look inwards, to contemplate where we are, what we do and to question our future.
There is much to celebrate and Earth Day is an opportunity to focus on those good things: biodiversity, water, clean(er) air … life, living, loving, and caring for and about others – these are aspects that the down time the virus has brought to us. Time to think about the food we eat, where it comes from, what we eat, how much food we really need, how to be innovative about making meals from food we already have at home instead making a needless trip to the local supermarket.
The internet abounds with ideas on how to cook / bake with ever fewer ingredients; how versatile other ingredients can be as substitutes for those we have run out of. Are we eating less / more healthy food / snacking less? Those with gardens appear to be appreciating them more – I certainly do – and have greater empathy for those who do not.
Earth Day this year is one of contemplation and appreciation. As we have been housebound for 27 days now I look back with a sense of nostalgia to various trips we have undertaken to game reserves in South Africa – at the time, never doubting that we could return whenever we had both the time and the resources to get there. The virus had other ideas.
We do not have to travel very far to observe Cattle Egrets as flocks of them follow the Urban Herd around all day and many fly over our garden at the end of each day on their way to perch in one of the tall trees near the centre of town.
Ostriches are always a delight to see in the various game reserves we have visited in the country. We used to see a lot more being farmed around here – South Africa provides 60% of the ostrich-meat supply market despite farmers having to battle with problems such as drought and avian influenza – which has made these birds very familiar over time. They are still wondrous to see in the wild.
Now we can only imagine and remember the joy of driving round the corner of a dirt road to meet an Elephant and her calf walking towards us.
When will I see a Waterbuck again?
Or Impala grazing in the rain?
Or a Lioness looking at me contemplatively?
These and all the other birds and animals will still be there when we are ‘free’ again. I remain thankful for that.
Enjoy Earth Day in your own way.
Symbiosis is an interesting word meaning ‘living together’ which derives from the Greek syn = together and biono = living. It is frequently used in the form of symbiotic relationships between plants / animals / birds. A very common example of a symbiotic relationship between birds and animals is the presence of Cattle Egrets that follow close in the wake of grazing cattle.
They are also often seen in the company of buffalo or zebra.
What these birds are doing is catching insects that are disturbed by the movements of the grazing animals. This is a type of commensalism whereby the birds benefit enormously from the animals, although what the latter get out of the relationship is uncertain – unless the birds act as a warning system perhaps.
I suspect this Red-winged Starling was using the bull as a convenient perch for the same reason – there were several other cattle grazing nearby.
A symbiotic relationship with more mutual benefit would be this one between the Red-billed Oxpeckers and the Nyala bull: the oxpeckers probe the skin and ears of animals in order to feed on the parasites harboured there. This benefits both them and the animal concerned.
In the case of these oxpeckers on a Cape buffalo, only one appears to be ‘working’, while the others are enjoying a free ride!
