PREENING PIED CROWS

Usually one only sees the white breast of a Pied Crow (Corvus albus) as it flies overhead. In fact, I mostly see Pied Crows when they are on the wing and so it was interesting to watch this pair sitting on top of a stunted Huilboerboon (Schotia brachypetala) preening themselves despite the wind rocking them to and fro.

STONE THE CROWS

No, I do not mean that literally – that is the last kind of behaviour I would encourage! Rather, stone the crows is a phrase generally understood to be an exclamation of incredulity or annoyance. Although this is not a term widely used in South Africa, it occasionally springs to mind when crows squawk and gurgle as they fly over my garden or settle in one of the tall trees before being mobbed by some of the smaller denizens of the area.

Until about five years ago, crows of any kind were more often seen in the area known as Burnt Kraal and around the municipal dump, both on the outskirts of our town. Now I see both Cape Crows and Pied Crows daily in the suburbs – occasionally even a White-necked Raven.

The Pied Crow (Corvus albus) is the most common and widespread all over the country.

It is easily recognised by its white breast and neck, both while flying or when it is on the ground. They have been recorded as being on the increase in South Africa, partly because of the availability of nesting sites on electrical poles coupled with roadkill as an available source of food. Any traveller along our network of roads will attest to this. The Pied Crow is highly adaptable in terms of the food it eats, which includes an omnivorous diet of fruit, seeds, small mammals, birds, reptiles, amphibians and insects. They are known to raid the nests of birds for either eggs or nestlings, so it is no surprise that the Fork-tailed Drongos nesting the fig tree regularly chase one off the property. I wonder if they say stone the crows, wishing they could do this literally!

Pied Crows also remind me of a song we used to sing in primary school. It began:

Aai, aai, die Witborskraai!

Hiervandaan na Mosselbaai

–Oompie wil na Tannie vry,

maar Tannie trek haar neus opsy.

The Cape Crow (Corvus capensis) used to be called (and is still widely known as) the Black Crow – perfectly understandable as it is a glossy black all over.

It is a common resident in grasslands as well as in the drier regions of the country. They are ubiquitous in the Addo Elephant National Park, where we saw flocks of close to fifty scattered across the veld in the vicinity of Carol’s Rest and elsewhere. They too are omnivorous birds, feeding on insects, small reptiles, birds, frogs, seeds, fruit and carrion.

FRIEND OR FOE?

Farmers do not regard these wily creatures as friends, yet they are a delight to observe in their natural habitat.

Black-backed Jackals tend to mate for life and so, should you see one in the veld, you can virtually be certain there is another in the vicinity. A pair of them trotted purposefully along the edge of Ghwarrie Pan shortly after sunrise one morning. It was at Carol’s Rest though that we observed an interesting altercation between a Black-backed Jackal and a Pied Crow.

The latter had already experienced an unsuccessful attempt to share the small waterhole with an Egyptian Goose that had arrived out of the blue – with no intention of sharing the water with anyone!

Once the Egyptian Goose had drunk its fill and flown off, the Pied Crow was in no mood to be ousted from its drinking spot again and made sure the approaching Black-backed Jackal was aware of this. Doubtless, the jackal was thirsty too and so it kept trotting purposefully towards the water. The crow opted to make a pre-emptive strike.

It continued to harass the jackal until it gave up and moved away to drink from the overflow a little further down the slope.
