Deconychura longicauda pallida

Hitherto considered conspecific with D. longicauda and then usually also with D. typica, but differs from latter in characters given under that species and from former in its shorter tail (in male 92–105 mm, n=4, vs 107–109; at least 1); whitish vs strong buffish chin and streaks on throat to breast (1); and distinctive song, a series of c. 8 flat whistles vs a series of 6–10 long upslurred whistles (both gradually descending in pitch), hence having much shorter notes (3) with pitch of first note much higher (3) and note shape different (ns[2])#R. Populations in Andean foothills of E Ecuador apparently belong to connectens, but adjacent lowland birds may be of race pallida; in these foothills, either connectens or an undescribed taxon sings a very different song, a series of c. 10–14 double notes, slightly descending in pitch, suggesting a species-rank difference; undescribed taxon, perhaps same, reported from foothills of NE & NC Peru#R. Recent analysis of whole genus using voice, morphology and genetics#R proposed promotion to full species status of the three races currently included herein, as well the undescribed taxon from Andean foothills; however, differences appear slight, and vocal analysis based on very small samples, some of which may be unrepresentative. Names pallida and connectens published simultaneously; former awarded priority by First Reviser#R. Three subspecies recognized.
