Río San Miguel, Ayacucho, Peru.
Until recently considered a race of H. cantator (which see). Is partly sympatric with H. peruviana and differs from this and all other species formerly grouped under H. cantator in its plain pale yellow throat to belly (3); very weak rufous flanks (2); pale olive-grey vs rufous-toned rump (2); and unique “common call” of two raspy notes (4); also appears to lack “chirr” calls of other species. Validity of race collinsi may require reappraisal. Two subspecies recognized.
