Straight-billed woodcreeper, Inírida river, Colombia
We found wood creepers to be omnipresent in the Colombian Amazon, but they are a tricky category to identify. I identified this one based on the bill (short and dagger-like, not curved), and the streaks on the head yet not the mantle, which is deep red overall. Almost identical reference here:
