An odd, warbler-like bird found near treeline in the Andes of northern and central Peru. Pardusco means “brownish” in Spanish, and that fits the bird very well. It is best identified by its lack of field marks, its small and pointy bill, and its specialized habitat. Behavior is also a good clue, as it is typically found in little flocks that chatter and squeak as they move through elfin forest, often accompanied by other species.
