The scientific name has changed from andicola to albicauda because andicola was unavailable for this taxon; as a result, the subspecies was also changed, andicola to pollens.


Two subspecies are recognized[1]:

  • A. a. pollens:
  • Andes of Ecuador (north to Imbabura)
  • A. a. albicauda:


High-altitude shrub and grassland, farmed arable and pasture, semi-arid bushy country, open areas with sparse vegetation and scattered rocks.



They use a conspicuous perch to hunt for their prey, which consists mostly of large insects, small mammals, lizards, frogs, eggs or nestlings of other birds.
