Occurrence, nutrition and reproduction
Salvin wood warblers occur in the mountain ranges of the Sierra Nevada de Santa Marta in northern Colombia. They inhabit moist mountain rainforests , cloud and cloud forests and bush-like forest edges at altitudes of 1500 to 3050 meters, but are mostly found above 2000 meters. At altitudes of 1500 to 2000 meters, they can often be seen together with the larval wood warbler ( Myioborus miniatus ). They feed mainly on insects . The bowl-shaped nest is placed well hidden on the ground or close to the ground. The breeding season has not been carefully studied. There is one recording in May with a clutch consisting of two eggs. A young bird that had just fledged was sighted in July.
