Ploceus megarhynchus Hume, Ibis, 1869, p. 406 (Kaladingee, Kumaon Terai) ; Blanf. & Oates, ii, p. 177 (part).
Vernacular names. None recorded.
Description. - Adult male in Summer. " General colour bright yellow (brightest on head and dull and impure on rump), with the following exceptions: - lores, round the eyes below, and ear-coverts dark brown; upper back, wings and tail blackish brown, each feather edged, entirely or externally, with light brown, on the uppermost part of the back with yellow; under wing-coverts dirty white" (Finn).
Colours of soft parts. " Iris bright light brown; bill black, fleshy-white at base; feet dark brownish fleshy, claws blackish horny " (Finn).
Measurements. A decidedly larger bird than P. philippinus. Wing 76 to 82 mm.; culmen 18 to 19 mm.; tarsus about 23 mm.
Winter plumage. Similar to the preceding bird but richer and more rufous above and deeper rufous-fulvous below.
Female in the breeding season has the head less streaked than the preceding bird and tinged with rufous-yellow; below, the chin, throat, breast and flanks are tinged with yellow. In Winter they seem to differ but little from P. philippinus except in their larger size and bigger bills.
Distribution. Hume's birds were obtained in the Kuman Terai but since then nothing more has been learnt about this Baya's habitat until Mr. H. V. O'Donel discovered them breeding in the Buxar Duars and obtained a series of skins which he presented to the Bombay N"at. Hist. Society. It seems therefore that this species is a form inhabiting the lower Terai from the Plains up to some 3,000 or 4,000 feet.
Nidification, The nest is described by O'Donel as a round untidy structure quite unlike the nests of P. philippinus, which is a common breeding bird in the same district.
