A species typical of heavy undergrowth in mixed broad-leaf and coniferous forests, this warbler places its bulky and moss-lines nest in a dense tangle of vegetation low in a bush or coniferous tree. It feeds almost exclusively on insects found on leaves and bark in the summer. During Fall and Winter it includes a large amount of fruits and seeds in its diet.

The four-digit banding code is BTBW.
