It wasn’t just a discrete little tap, tap, tap on the window frame, it was a very loud and insistent hammering. The first time I heard it early in the morning I thought what an inconsiderate visitor this is. It must be an emergency.
It was a visitor, but not an emergency. Clinging to the outside of the window was one very busy Olive Woodpecker. In the past we’ve had sunbirds at the windows, and wood hoopoes admiring their reflections, even Cape Robins taking a short cut through the house, in the window and out the door, picking up a bite to eat from the cat’s food on the way, but never woodpeckers.
Initially we thought this is nice, nature at our window while we drink our coffee, close up of woodpeckers at work, and stood admiring the beautiful plumage and the way the little head moved so fast it was a blur. The strength and the ability of such a small bird to absorb the shock and unrelenting percussion of the jack hammer beak was amazing to watch.

But how do woodpeckers hold vertically onto a tree, or in this case a window, and avoid banging themselves silly? As explained at ornithology.com, unlike most birds which have three forward toes and one hind toe, most woodpeckers have two toes in front and two at the back. This toe arrangement, along with stiffened tail feathers, allows the birds to lean back and pound away. In addition, a special muscle and tendon mechanism at the back of the jaw acts as a shock absorber. And if that’s not enough specialized equipment, the bird even has little hairs growing over its nostrils so it doesn’t inhale wood dust.
But after the second day, we thought perhaps we should go and check on what was happening on the outside. The damage to the window frame was quite a surprise. These holes weren’t little beak marks denting the timber, they were deep tearing gouges penetrating the Meranti window frames right through to the other side, with some even enlarged to almost three centimetres across. There must’ve been five or six holes, all at varying stages of completion. The reason for all this activity was hard to understand.

That old tongue twister comes to mind: How much wood would a woodpecker peck if a woodpecker could peck wood? The answer would seem to be an endless amount. On doing a little research it became apparent that there are three reasons for the woodpeckers’ pecking. The first is to catch insects and their larvae living under the bark of trees; then there’s making holes for a nesting cavity; and thirdly, to communicate. It would seem our woodpecker was using our windows to communicate. The message being sent out could either have been about territory or to attract a mate. This form of hammering, called drumming by ornithologists, is usually performed on something with sufficient resonance and echo to make a noise loud enough to carry as far as possible. Such as a window frame.
Olive Woodpeckers are monogamous and are usually found in pairs. The male is easily identified by his red cap
Although woodpecker damage is a very common problem in America and Canada, it doesn’t seem to be as much of a problem here. Our situation, with damage to window frames seems to have been unusual. So, sadly, we had to persuade our bird to move on to other drumming venues. The holes were filled and quite an elegant solution found as a discourager. Spirals of silver aluminium, turning and flashing in the sun were hung over the windows and the woodpecker can now be heard high in the oak tree beating out its message.

Olive! I’m so used to seeing B&W. Certain woodpeckers here like to drum on metal flashing or stovepipes and it can get quite annoying if it is your house, but it always makes me smile at the male’s earnest quest to attract a mate. 🙂

The olive is unusual as most other species here are heavily barred.I was not aware till now of woodpeckers drumming on buildings. Drumming on stovepipes must make quite a din, but all in a good cause 🙂

How fascinating. I love woodpeckers and when living in Massachusetts became very accustomed to them drumming on the wood siding of the house. In Britain and here in France they tend to stick to the trees – my favourites are the jet black variety with it’s flashy red beret the same as your olives.

I love watching woodpeckers. We mainly attract downy woodpeckers to our
suet feeders.

Hmmm, yes, I imagine there must be other places for him to knock. At first I was afraid that you’d found out that you had insects living in your door!

This drumming behaviour from woodpeckers in the breeding season (courtship phase) on resonant surfaces, including gutters, window frames, wooden walls, and even street signs, seems to be more common in North America than in South Africa where it seems to more unusual – possibly because wood is generally less often used as a building material here? There are lots of websites explaining how to deter woodpeckers from drumming on parts of houses. Unlike Barb, who wrote this post and had the interesting and easily solved incident with the Olive Woodpecker in her Western Cape garden, we have not had any similar incidents at our (metal-framed) windows.

What an astonishing tale. I guess this was the kind of vandalism you felt able to tolerate, though. For a while.

I would think it is unusual. Judging from what Barb says in her post, they only tolerated it a few days before creating their “discourager”.
