“Immature.—Differs from the adult in having the middle tail-feathers with the shaft not naked and with no developed spatula, although the webs become narrower before the end; the tips of the two middle tail-feathers are blue; the lateral tail-feathers have, towards the end, less blue than in the adult bird.” (Salvadori.)
“We found this beautiful species common about the foot of Monte Arayat, in central Luzon, though we failed to meet with it in Albay or Catanduanes. In north Luzon it was abundant in the maize fields, feeding on the flower at the top of the plant. Young were obtained in the month of May in Isabella.” Whitehead, Ibis, (1899), 397.
