creeper – certhia
The creepers are very hard to spot and even harder to photograph because they constantly move. They are creeping up the tree looking for spiders and insects in the bark and then the fly down to start all over again. Their feathers are a brownish color mixture and therefor they look like a moving piece of bark.
The short-toed Tree-creeper (Certhia brachydactyla) and the Brown Creeper (Certhia familiaris) are very hard to separate. The easiest way is by their song.
I’d say that’s more hanging than creeping:
