“Very common throughout the Islands. Builds edible nests. Nests always in caves, and composed chiefly or entirely of secretion from the mouths of the birds. When the birds are persistently robbed, however, they seem to become discouraged, and mix in grass, stems of small plants, moss, etc. Two or three white eggs are deposited. They measure: 15.2 to 17.7 by 10.1 to 10.9. Fourteen males from Siquijor average, 92 in length; wing, 92; tail, 41; culmen, 4; tarsus, 8; middle toe with claw, 9. Bill, legs, and feet black.” (Bourns and Worcester MS.)
