This bird inhabited regions similar to those in which its northern
representative, inexicanus, is found in the southwestern United
States, namely, open thickets and groves of low trees, often in the
vicinity of dry watercourses, where it chose low perches, frequently
where a network of small limbs protected it from the sudden on-
slaught of bird-eating hawks. The young males carry the streaked,
immature plumage until late winter following the season in whicii
they were hatched, as is shown by three males from the Territory of
Formosa, killed in August, which are in transition from this streaked
phase to the brilliant plumage of the adult. The period from Sep-
tember, when they had attained full feather, until December consti-
tuted the mating season during which their beautiful display, in
which they flew out with head erect and crest raised, and supported
themselves in air with rapid beats of the wings, vivid burning spots
of red that instantly attracted the eye, was seen frequently. At a
distance of a few yards, during this action, a thin, steely note tsit-
tsur-ee-ee was faintly audible. Occasionally one gave a low, crackling
note like the sound made by breaking dry twigs. An immature
specimen secured December 28 had only recently left the nest.
In some localities the brilliant display of the male had given this
species the name of hrazita de fuego; elsewhere it was called chur-
rinche.
