Species Spotlight: Wallcreeper

January 2, 2026 by Kai Pflug 1 Comment

In Chinese, words are often composed of two characters, and the pattern is frequently the same. Take this example, “meili”:

  • Mei means beautiful
  • Li means beautiful
  • And to nobody’s surprise, the combination of both characters again means beautiful.

The scientific name of the Wallcreeper, Tichodroma muraria, follows a similar pattern. Tichodroma comes from Greek teikhos, meaning wall, while dromos -also in Greek – means runner. And the muraria then is Latin for “of the wall”.  

Much like my cats are obligatory carnivores (I sometimes tell them when they try to eat something else), wallcreepers are obligatory insectivores. And indeed, getting the photos shown in this post at Laojunshan, Yunnan, China, I was lucky to encounter a wallcreeper struggling to deal with a rather large insect and thus mostly ignoring the insistent photographer.

The HBW untypically and somewhat surprisingly gushes about the species: “Despite its very large but discontinuous range … the long-billed, rock-climbing Wallcreeper is arguably one of the most visually stunning, and sought-after, birds in Eurasia.”

Why there is a perceived contradiction between the range and the fact that the bird is stunning and sought-after is a bit of a mystery to me, though.

Apparently, in the past, the wallcreeper was given its own family (yes, I know that this is not the correct way to say it, but it sounds fun), while nowadays, it is regarded as a subfamily within the nuthatches.

Given what an exciting bird this is, the scientific literature on it is surprisingly sparse and – frankly speaking – quite boring. Mostly of the type of “Review of the status in Iran”, “Distribution in Catalonia”, or “New Record in Mongolia”. Not the kind of papers I can extract vaguely interesting semifacts from.

So, just a few more photos …

As far as I can tell, my photos show a bird of undefined sex in non-breeding plumage, consistent with the time the photo was taken (second half of October). A breeding male would have a wholly black throat, while the throat of a breeding female would have a black spot at the throat surrounded by white.

One interesting behavioral aspect is the frequent wing-flicking of the bird (which I did not see much of as the bird was very focused on dealing with its insect prey). Apparently (according to the HBW), this serves to display the red and white wing markings, signaling the presence of the bird to conspecifics and substituting for the rather weak contact calls of the species.

After the bird I photographed had swallowed the edible parts of its insect prey, it went back to its day job of searching for insects on the rock walls, not afraid to venture into some of the deeper fissures in the rocks. This got me what I think was the best photo of the whole trip to Yunnan this time.

Kai has lived in Shanghai for 22 years. He only started birding after moving to China, so he is far more familiar with Chinese birds than the ones back in his native Germany. As a birder, he considers himself strictly average and tries to make up for it with photography, which he shares on a separate website. Alas, most of the photos are pretty average as well. He hopes that few clients of his consulting firm—focused on China’s chemical industry—ever find this blog, as it might raise questions about his professional priorities. Much of his time is spent either editing posts for 10,000 Birds or cleaning the litter boxes of his numerous indoor cats. He occasionally considers writing a piece comparing the two activities.
