THE BLACK-NAPED INDIAN ORIOLE.
Length, 10; wing, 6 ; tail, 3.5 ; tarsus, 0.87 ; bill at front, 1.12.
Bill pinky-red ; irides rich blood-red ; legs plumbeous.
Bright yellow, greenish on the back and coverts; a black horseshoe mark extending from the base of the bill through the eyes to the nape ; tail black ; the central feathers barely tipped yellow, the others tipped broadly, the outermost feathers for 1 1/2 inches or so; wings black, the secondaries broadly margined with pale yellow, the tertiaries with the whole outer web, and part of the inner webs, greenish yellow; primaries also tipped with the same ; a bright yellow wing-spot formed by the tips of the coverts of the primaries.
Females differ in being slightly greenish above, and in the yellow generally being not quite so vivid.
The young are yellowish-green above, with little or no trace of the occipital crescent; whitish beneath, with dark central lines ; bill infuscated.
In a further stage the under-parts are a weaker yellow, with black shafts to the breast-feathers more or less developed.
The Black-naped Indian Oriole is very rare. It has only been procured at Savantvadi and Ratnagiri. Colonel Swinhoe saw it at Manpore, Central India.
