The White-browed Spinetail was the only species of Spinetails we ever saw in Colombia. It inhabits the paramo at Nevado del Ruiz, at an altitude of 4,200 meters above sea level. Its body coloration is composed of brown back and head, gray belly, chest and throat, and a gray supercilliary on top of the black eye. With this colors, it might look very dull and uninteresting, however it is an amazing fact for this little bird to withstand the lack of oxygen and low temperatures of this elevation, specially during the night.
