Industrial biodiversity 3 : an hour spent replacing tyres in Maitland

Birds succeed in making a living in pretty hard circumstances. This includes the jungles of tar, concrete, wires with assorted purposes strung between poles, with a few palm trees in the mix. Here’s an example of industrial biodiversity in Maitland, a suburb of Cape Town

These tyres had given me 50,000 km, and had more than reached the legal limit. With a bird ringing course, 700 km away, looming next week, it was time for decisive action. So, at 08h00 today, the magnetic triangle showing that this vehicle was number one in the queue was put on the bonnet. Replacing four tyres, wheel alignment, etc, takes about an hour. You can use that hour or lose it. I had taken my camera, and in the hope that I could wander around outside, instead of reading old magazines about irrelevant topics in the waiting lounge, however comfortable that is. The hour produced enough of interest to generate this little blog. A camera trap would probably have produced some nightlife, in the form of rats, but the focus here is only on birds.

Birds and steel

We seldom look up when we are on pavements and crossing roads. That makes sense, because we should avoid bumping into other pedestrians, and getting knocked over by vehicles. But the birds have endless opportunities to inspect the infrastructure above us.

Laughing Dove : Industrial biodiversity in Maitland
The Laughing Dove is amused by the Heath Robinson-ness of the wiring. But it is quite neatly done. One wonders when it was done, probably measured in decades, and how many kilowatts of electricity have flown safely along those wires. The pole is a bit rusty, and could use a coat of paint to prolong its life. BirdPix 291957

Birds and tar and concrete

Rock Dove : Industrial biodiversity in Maitland
The winter storms of 2024 have played havoc with Cape Town’s road, and and water has exploited every little weakness, enlarging cracks and turning them into potholes. The texture provides a modest degree of camouflage for the Rock Doves. BirdPix 291963

House Sparrow : Industrial biodiversity in Maitland
It is 5 September, so it is spring and its breeding season for the House Sparrows. This down feather, possibly from a dove, is destined to become lining for a nest. In the meantime it has been manipulated into a scruffy horseshoe moustache which an ancient cowboy would be proud of. BirdPix 291961

Birds and air

Birds and green

This part of Maitland generally lacks much in the way of green …

Common Starling
… but this palm tree is precious, not only for the nesting Common Starlings, but especially because it provides a landmark to find the tyre shop, and gives its name to the business …. BirdPix 291958
Palm Tyres

While I was still engrossed in photography, my tyres were fitted and the wheels aligned! Now I feel more comfortable setting off for the bird ringing course at New Holme, starting next Monday.

The industrial biodiversity of Maitland doesn’t have much variety, but the antics of the birds filled an hour with interest and amusement. The BirdPix section of the Virtual Museum benefitted too!

Although citizen science in biology is Les’s passion, his academic background is in mathematical statistics. He was awarded his PhD in abstract multivariate analyses in 1973 at UCT and what he likes to say about his PhD is that he solved a problem that no one has ever had. He soon grasped that this was not the field to which he wanted to devote his life, so he retrained himself as an applied statistician, solving real-world problems.
