We are getting back into our Pretoria routine after 3 months in Mossel Bay, and I decided to go out atlasing in Roodeplaat Nature Reserve one morning this week. Heading into summer the weather in Pretoria is already warm with temperatures in the low 30’s and the skies are clear – some rain has fallen but the ‘big’ summer rains accompanied by the typical highveld thunderstorms have not yet arrived – hopefully they are not far off.
It was a good morning’s atlasing with 71 species logged on the Birdlasser app, including one which put on a brief display for me (well that’s what I like to think) ….
I was out of the car listening to a Lesser Honeyguide calling near the nature reserve offices, when I saw what looked like a woodpecker fly from a tree to a bare wooden utility pole. I could not make out what it was as it seemed to be purposely hiding from me so I approached carefully until I had a partial view and took a few record photos.
It then started pecking at the pole in a rhythmic fashion creating a loud drumming sound and I immediately wondered why, as there was no hope of anything edible to be found and the pole was completely unsuitable for nesting or similar purposes.
Here’s the short clip I filmed of the woodpecker, which I later identified as a Bearded Woodpecker, in action – do excuse the shakiness of the images – I had to film it at a distance on full zoom so as not to scare it away and the wind blowing didn’t help matters.

A read through of the species habits on the Roberts app on my phone provided the following insights into this behaviour – nothing to do with food or nesting it seems –
Presence often given away by loud, distinctive call, or by loud tapping (while foraging), or drumming.
Moves out of sight behind a branch in response to danger.
Both sexes drum frequently, mostly early morning; used in territorial advertisement and to establish contact with partner.
Drums in bursts of ca 1 sec at ca 12 strikes/sec, beginning fast, then slowing; usually on a high dead branch (same branch often reused); audible to 1 km.

It flew off after a while and I continued with my atlasing, pleased at having witnessed this behaviour and at having everything one wants to know about birds available on my iphone.
