the lower back long, but somewhat sickle-shaped and hanging over on
each side, brown or black in color, broadly streaked with white;

horn-color, the mandible more yellow; feet dark brown. Length, 173;

"Not rare in Palawan, but difficult to see, as it is shy and
protectively colored. It seems to be a very pugnacious bird, and
the males can be readily called by imitating their note. They come
apparently prepared to do battle. We found P. falcata at a height of
760 meters on Mount Pulgar.
"A male measures: Length, 203; wing, 86; tail, 70; culmen, 26; tarsus,
33; middle toe with claw, 29. Iris reddish brown; legs and feet dark
gray; upper mandible black, lower gray; breeding in January." (Bourns
and Worcester MS.)
