White says that in Salta "this bird frequents the gardens in the
vicinity of the houses, where it vigorously pursues the ants amongst the
branches of the trees." Mr. Barrows says that near Concepcion it had the
general motions and appearance of a Titmouse, thus differing widely from
the other members of the genus.
