As most other individuals in the Woodcreeper family, this bird is difficult to identify to species level. The reason is that they move rapidly within the dark forest, where light is scarce, and their plumage differences are pretty subtle, not to mention their body shape and size. I met this bird for the first time at Refugio Los Cusingos, during a Birdwatching Trip with Fundación Rapaces de Costa Rica. At least three individuals along with eight Gray-headed Tanagers were catching insects near to an Army Ant swarm, pretty close to the trail. We were able to see all the action for about half an hour, and got very close to the birds, without them showing the minimum sign of stress. They just kept on hunting.
