366. Aegithina nigrolutea

(366) AEgithina nigrolutea.


Iora nigrolutea Marshall, S. F., iv, p. 410 (1876) (Meerut). AEgithina nigrolutea. Blanf. & Oates, i, p. 232.

Vernacular names. The same as for AEgithina t. tiphia.

Description.— Male breeding. Upper back bright golden yellow, delicately fringed or stippled with black; remaining upper parts black, the yellow showing through more or less on the lower back; tail broadly tipped with white; scapulars, lesser coverts and greater coverts black, the latter tipped with white and the median coverts wholly white; quills black, narrowly margined with greenish, the outer secondaries tipped with white and the inner tipped, and margined with white; sides of head and neck and whole lower plumage bright yellow; under wing-coverts white.

Male in non-breeding plumage loses all or nearly all the black on the upper parts which become dull greenish yellow.

Colours of soft parts. Iris dark brown ; bill horny plumbeous, the culmen darker; legs and feet light plumbeous.

Measurements. Total length about 130 to 140 mm.; wing 60 to 66 mm.; tail about 44 to 50 mm.; tarsus about 17 to 18 mm.; culmen 10 to 11 mm.
Female. Whole upper plumage greenish yellow; the upper tail-coverts black, fringed with green; tail ashy-green, the central pair of rectrices nearly all white and the remainder broadly edged with white, yellowish-white or greyish-white; rest of plumage like that of the male but the black of the wings replaced by blackish brown.

Distribution. Takes the place of AE. t. tiphia and AE. t. humei to the north-west of India. It is found in Cutch, Rajputana where it overlaps the range of AE. t. humei for some distance, Southern and South-Western Punjab, North-West Provinces; occasional in the north of the Central Provinces and north of the Ganges as far as Behar and the Santal Parganas, much overlapping the range of AE. t. tiphia. Some authors consider both this bird and the last to be merely geographical races of AEgithina tiphia, but their actual breeding ranges overlap so constantly without a corresponding intergrading of form that it seems imperative to give them the status of full species.

Nidification. Exactly like that of AEgithina tiphia. Twenty-four eggs taken by Barnes, Kemp and General Betham measure 17.1 x 13.1 mm.

Habits. Those of all the rest of the genus.
