“The differences between A. guillemardi and A. mindorensis are very slight. Sharpe, Ibis (1894), 254, states that the latter is lighter gray in color than the former. On comparing specimens of these two species we are unable to perceive the slightest difference so far as the general color of the body is concerned. The feathers of the throat and crown in the male of A. mindorensis are, however, lighter gray than in the male A. guillemardi, so that the black markings on the side of the head stand out more sharply.
“We have a large series of birds from Tablas. In nearly all of them the under wing-coverts are barred with black and white. This we consider to be a sign of immaturity, however, and we do not regard them as specifically distinct from the Mindoro birds, though their general color is slightly darker, and the black head-marking less distinct.” (Bourns and Worcester MS.)
A nest and one egg were taken in Mindoro on April 26, 1905. The nest is composed of mosses, small leaves, lichens, and fine rootlets; the outside is covered with cobwebs which serve to hold the materials together and to fasten the nest to the fork in which it was built. The nest is about 115 mm. across the top and its outside depth is about 50. The ground-color of the egg is light gray with a slightly greenish tinge; a heavy and continuous wreath of spots and blotches encircles the shell near the plane of its short diameter; a few small spots are scattered about over the entire surface; the deep shell-markings vary from pale to dark lavender; the surface spots and blotches are reddish brown; measurements, 30.7 by 21 mm.
