The Santa Marta Warbler (Myiothlypis basilica) is a species of bird in the Parulidae family. They are extremely quick-moving, this was the only photo I got that was less blurry.
They are endemic to the Santa Marta mountains and your only chance to see them is on the excursion with the El Dorado Reserve Lodge.

I could only find one and it was taken by a Colombian birding guide. Notice how quickly the bird keeps moving?
