"Comparatively rare and usually frequents the loftiest trees. For a long time we mistook its deep booming note for the hoot of some great owl. Occasionally it comes down into low second-growth where it is easily shot, being very stupid about making its escape. "Iris with outer red and inner yellow or brown ring; legs and feet red; nails dark brown; bill black; eyelids red. Length 400." (Bourns and Worcester MS.) 41. ZONOPHAPS MINDORENSIS (Whitehead). MINDORO ZONE-TAILED PIGEON. Carpophaga mindorensis Whitehead, Ann. & Mag. Nat. Hist. (1896), ser. 6, 18, 189; Ibis (1899), 488; Grant, Ibis (1896), 476, pl. 11. Zonophaps mindorensis Sharpe, Hand-List (1899), 1, 65; McGregor and Worcester, Hand-List (1906), 12. Mindoro (Whitehead). "Adult male.--Most nearly allied to Carpophaga radiata (Quoy and Gaimard) but much larger. Top of head, neck, breast, and rest of under parts bluish slate-gray, darkest on belly and under tail-coverts, the latter indistinctly edged with rufous; forehead, cheeks, and throat pale whitish pink; feathers surrounding eye and forming a patch above ear-coverts, blackish gray; hind neck gradually shading into sooty black on the mantle and interscapulary region; scapulars and inner wing-coverts bronze-lake, changing to bronze-green on the rest of the wings, rump, and upper tail-coverts; primary quills blackish gray, the inner ones glossed on the outer web and toward the extremity with metallic green; tail-feathers black, glossed with purple and green, and with a wide gray band across the middle; under wing-coverts and axillars slightly glossed with bronze. Length, 482; exposed culmen, 23; wing, 234; tail, 178; tarsus, 35; middle toe with claw, 51. "Adult female.--Similar to the male but rather smaller, and the under tail-coverts distinctly margined with chestnut. Length, 445; exposed culmen, 23; wing, 223; tail, 159; tarsus, 33; middle toe with claw, 46." (Whitehead.) This species is much larger than Zonophaps poliocephala from which it differs also in the following points: A large black patch on ear-coverts and surrounding eye; forehead, cheeks, and chin fawn-color; occiput, neck, crop, breast, abdomen, and under tail-coverts gray. "Male.--Iris bright yellow, with an outer ring of red; orbital skin lake-red, with a grayish yellow space between the rings; bill black; feet coral-pink. Female: Iris straw-yellow, with an outer ring of golden brown; orbital skin orange-yellow, bill olive-brown, black at tip; feet salmon-red; nails black. "This species is more often met with singly or in pairs, but sometimes as many as four birds were seen together; they were feeding on some large purple colored fruits as big as a pigeon's egg. C. mindorensis, like the last species (Zonophaps poliocephala), has a conspicuous fleshy ring outside the eyelid. * * * During dull misty weather, especially just after daybreak, the penetrating booming note is more often heard than on clear days."
