Resources, nutrition and reproduction
Brown Cap Warbler inhabit forest edges, clearings and mountain forests at altitudes of 1400-3200 meters. In Argentina, they are usually to be found at altitudes from 1400 to 1700 meters. In Cochabamba, in Bolivia they sometimes also occur in 3800 meters height and pull in the south of Bolivia outside the breeding season to a height of 400 meters.
Your consisting of insect food they are looking for in the lower and middle regions of the vegetation mostly at altitudes of 2-8 meters. In their wanderings they are usually in pairs or in small groups - often with other species of birds - to watch. However, they can also occur as individual animals.
About nesting and hatching and fledging times, there are no studies. Just fledged young birds were seen in January and February in the department of Tarija in Bolivia.
System
The Tepuiwaldsänger ( Myioborus castaneocapillus ) was combined with the earlier Brown Cap Warbler to one species. By disjunct distribution and because of different vocal sounds of Tepuiwaldsänger was recognized as a distinct species, although both species are related undoubtedly close and might be sister species.
